At present, the video recording function can make various kinds of videos, such as making slow-motion videos or fast-motion videos, etc. However, making various kinds of videos is based on that a section of the captured video is imported into a video editing software or a corresponding slow playback process or a corresponding fast playback process is performed on an editing page, and then making a video is completed, thereby achieving a slow-motion video playback or a fast-motion video playback. In addition, in the prior art, there are platforms with fast and slow speed capturing functions, but the fast and slow speed herein is only processed and presented to a user in real time during capturing, and the requirements for real-time processing are difficult and the recording time is short, usually 1s. Therefore, the video speed change recording mode in the prior art has complicated operating steps and complicated processing procedures, and cannot provide convenient operation for a user, thus affecting the user experience.
In order to solve the above problems, the technical concept of the present disclosure is that a speed change triggering operation can be configured, i.e., by recognizing the speed change triggering operation and an acquired second speed change mode for speed change recording, firstly, based on the second speed change mode, a first speed change mode matching the second speed change mode (i.e., a speed change direction of the first speed change mode is opposite from a speed change direction of the second speed change mode and a speed change speed of the first speed change mode is the same as a speed change speed of the second speed change mode) is acquired, then the video image captured after the target object recognized in the captured video image presents a target state is played at a changing speed according to the second speed change mode, which is used to prompt a user to start a speed change processing, and then a part of the video image in the target video generated by the video image and the audio is played at a constant speed and a part of the video image is played at the second speed change mode, while ensuring that the audio in the target video is played at a constant speed, thereby completing the speed change processing for the video. The processing procedure is simple and the operation steps are simplified, causing the user to realize speed change recording through convenient operations, thereby improving the user experience.
The technical solutions of the present disclosure will be explained in detail in the following specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.
In practical applications, the execution subjects of the embodiments of the present disclosure may be a terminal device, such as a mobile terminal, a computer device (e.g., a desktop computer, a notebook computer, an all-in-one computer, etc.), and the mobile terminal may include a mobile device with a playing function, such as a smart phone, a handheld computer, a tablet computer, a wearable device with a display screen, etc. In practical applications, a displayed user interface, such as a capturing interface, can be used to capture or record a target object, where the target object can be a person, a scene, etc., and the playing interface can be used to play a target video, and the target video can be an audio and video processed by speed change recording, which is not specifically limited by the present disclosure.
In a scenario, referring to
The video processing method according to the embodiments of the present disclosure can be applied to capturing or recording scenarios, which are specifically video speed change recording scenarios, for example, triggering any configured special effect editing effect is supported, where the special effect editing effect is used to support the function of controlling video speed change recording; and can recognize whether the target state is presented in the captured video image, if the target state is recognized during the capturing or recording procedure, i.e., the triggering operation for controlling video speed change recording is detected during the capturing or recording procedure, speed change processing, such as speed change processing for a video image or speed change playing for an audio during capturing, can be realized, , without complicated operating steps. The present disclosure does not limit application scenarios.
The technical solutions of the present disclosure will be explained in detail in the following specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The terminal device can display a plurality of functions in the function display area in the capturing interface 10, such as a flip, a filter, a beautification, a countdown, a special effect editing effect, an album, selecting music, a capturing duration, etc., where the special effect editing effect herein can include a special effect editing effect used to support the control of video speed change recording function, such as a predefined sticker, in which the special effect can include the required speed change processing rate, recording at the required rate can realize speed change recording, and then the speed change mode (including speed change direction and speed change speed) configured by the special effect editing effect can be obtained by recognizing that the target object presents the target state; and selectable speed and speed change direction (fast or slow speed) for speed change processing can also be provided to a user through the capturing interface, and then the target state presented by the target object is recognized through the recognizable speed change trigger mode configured based on the speed change mode selected by the user in combination with the special effect in the special effect editing effect.
The special effect editing effect configured by the embodiments of the present disclosure can control speed change recording by recognizing trigger actions or specific objects. Take a sticker as an example, the sticker can be configured as follows: the sticker starts capturing and resets; for the sticker, recording is capable of being valid, but the preview is invalid; the corresponding speed change rate of the sticker is configured in the resource package; the speed change playing event and speed change rate should be transmitted to a video expression (VE) software development kit (SDK) and the client in real time; a speed change recording message interface is added, which requires the slowest control within 10 frames; upon making a sticker, speed up and add a frame properly, and slow down after entering the editing page to become normal speed, and if a slow down effect following the image is required, the normal speed of the sticker is feasible, and afterwards, particle effect, physical effect (cloth, feather, etc.) can only be slowed down; the speed change playing event and the speed change rate are transmitted to the VE and the client in real time, a new interface may be needed herein; where this sticker is forbidden to be duetted; the sticker does not record the original sound; and the sticker needs to disable a function of adjusting the rate, which are not limited by the present disclosure.
Specifically, for example, a captured object is taken as a character, and the special effect editing effect itself is configured with a speed change trigger special effect and a speed change mode (it can be that one special effect editing effect corresponds to one speed change trigger special effect, and one special effect corresponds to one speed change mode; it can also be that one special effect editing effect corresponds to a plurality of speed change trigger special effects, and one special effect corresponds to one speed change mode; it can also be that one special effect editing effect corresponds to a plurality of speed change trigger special effects, and a plurality of special effects correspond to one speed change mode; and it can also be that a plurality of special effect editing effects correspond to one speed change trigger special effect, one special effect corresponds to one speed change mode, etc., and there is a mapping relationship between a special effect and a speed change mode, which is not specifically limited herein), the character is displayed on the capturing interface 10. On the capturing interface 10, the user can select a capturing duration, such as 15 s shown in
It should be noted that the operation sequence shown in (b) of
Take a special effect of the special effect editing effect as a smile as an example, if a smile action is detected in the capturing procedure, the operation for controlling video speed change recording is triggered, and the required speed change recording rate of the smile special effect (for example, 2x slow) is obtained, and at the same time, the audio triggered by the special effect will be processed and played in the background (here referred to as an audio and video terminal) at 2x fast. At this time, in order to ensure that the audio played during playing after recording is not interfered by the original sound played and/or randomly appeared before the speed change recording, captured original sound, such as ambient sound and played music original sound, is not recorded during the audio processing. It should be noted that, during the recording procedure, the speed change recording can be imperceptible to the user, and the video image and audio can be played at a normal speed, or in order to satisfy the user experience, for the speed change recording, the captured video image is played at a constant speed during the capturing procedure, and the unplayed part of the audio after the trigger speed change operation is turned on is played according to the second speed change mode that matches the first speed change mode required by the special effect. After the capturing is ended, the audio and video recorded before the special effect appears is played at a normal speed, and after the special effect triggering operation (i.e., speed change triggering operation) is detected, the video is played at a required rate of the special effect and the audio is played at a normal speed, so that the video speed change recording processing is realized, convenient operation is provided for a user, the processing procedure is simple, thus the user requirements are satisfied, and the operation experience of the user is improved.
The constant speed of video herein refers to the capturing speed, and the constant speed of audio refers to its own speed. Application scenarios are not limited by the present disclosure.
In addition, it should be understood by those skilled in the art that the “trigger” operation can include (but is not limited to): a click trigger, i.e., the user clicks the corresponding button or any position in the interface to realize the trigger; a gesture trigger, i.e., the user realizes a trigger operation by making a corresponding gesture; a voice trigger, i.e., the user realizes a triggering operation by issuing a corresponding voice instruction; an expression trigger, i.e., the user realizes a triggering operation by making a corresponding expression, etc., the present disclosure does not limit the triggering operation.
In an embodiment, the video processing method can be implemented in the following ways.
Referring to
S101: play an audio in a process of capturing a video.
S102: play a first part of the audio at a changing speed according to a first speed change mode in response to recognizing that a target object presents a target state in a captured video image; where the first part of the audio represents an unplayed part of the audio when it is recognized that the target object presents the target state in the captured video image.
The first speed change mode can be matched with the recognized target state. For example, if a smile triggers a speed change processing operation and the speed change mode is a 2x slow playback, the first speed change mode is 2x fast; and it can also be selected and input by the user before capturing the video, which is not specifically limited herein.
The method of the embodiments of the present disclosure can be applied to a terminal device, and the terminal device can display a capturing interface, which is a user interface for capturing a target object. The capturing interface includes a capturing area, a function display area and a capturing button, and a special effect editing effect module can be displayed in the function display area. By clicking the special effect editing button corresponding to the special effect editing module, a plurality of special effect editing effects can be displayed to the user in the capturing interface, where the plurality of special effect editing effects can include special effect editing effects for supporting video speed change recording function. Where the display modes of the plurality of special effect editing effects are not specifically limited.
Specifically, the user can start the capturing function by clicking the capturing button through the terminal device, and play a default audio or a special effect editing effect self-audio or an audio selected by the user in the process of capturing a video. In the capturing procedure, the terminal device detects whether there is an operation for controlling the video speed change processing in real time, i.e., recognizes whether the target object presents a target state, and if so, responds to the recognized target state. Firstly, when it is recognized that a target object presents a target state in a captured video image, a speed change mode of speed change playback required for the unplayed part of the audio, i.e., a first speed change mode, is obtained, where the first speed change mode can be a mode matched with a recording mode required by a special effect, for example, if the recording and playing mode required by the special effect is 2x slow playback, then the first speed change mode is 2x fast playback; and it can also be the mode of user input. The target state may include an interactive action and/or a preset object contained in the captured video, where the interactive action may include face and limb actions, such as smiling, blinking, raising a hand, lifting a leg, etc., and the recognized target objects are preset objects such as clothes, cars, buildings, etc., which are not limited by the present disclosure.
In practical applications, before the speed change trigger, the capturing interface needs to be displayed and the capturing function is turned on, before this, the user is required to select the special effect corresponding to a speed change recording, such as a special effect editing effect. Specifically, the terminal device can display the capturing interface and turn on the capturing function through the following steps:
Step a1: display the capturing interface for capturing the target object, where the capturing interface includes a special effect editing button for supporting and controlling video speed change recording.
Step a2: in response to a first triggering operation acting on the special effect editing button, upon receiving an instruction for instructing to perform a capturing operation on the capturing interface, perform a first capturing operation, and detect whether the target object presents the target state while capturing the target object in the capturing interface, where the target state includes a state in which the target object presents a target action and/or a preset object is presented in the target object.
Step a3: if it is recognized that the target object presents the target state in the video capturing procedure, execute an operation of controlling video speed change recording.
In the embodiments of the present disclosure, when a user capturing/recording a video (hereinafter referred to as the user) opens an application program, the terminal device can display a plurality of switching interfaces, and the user can click a switching button matching with the capturing interface to jump and display the capturing interface 10. Where the capturing interface can include a special effect editing button for supporting and controlling video speed change recording, which can specifically be a sticker, or it can also be that one sticker corresponds to turning on a recording function with one speed; it can also be that one sticker corresponds to recording functions with multiple speeds. Therefore, the recording function of the corresponding speed can be triggered according to the action of the target object or what the target object is. For example, smiling corresponds to 2x slow recording, waving corresponds to 2x fast recording, etc., or a special effect in a sticker can be used to trigger the speed change processing operation, and through selecting other special effect editing effects (such as a speed change mode special effect editing effect) before the video is captured, a user may perform a corresponding speed change processing in accordance with the acquired speed change mode input by the user upon recognizing the present target state during capturing, which is not limited by the present disclosure.
Taking the special effect in the special effect editing effect being configured with speed change mode as an example, where, in the capturing interface, before capturing is turned on, the user can click the special effect editing button to select the special effect editing effect used to support and control video speed change recording from the display area of the special effect editing effect, where, if there are multiple special effect editing effects used to support and control video speed change recording, the target special effect editing effect corresponding to the desired capturing speed can be selected from the special effect editing effect, and then the corresponding target triggering operation can be made based on the special effect in the special effect editing effect; and if the special effect editing effect used to support and control video speed change recording is one, the corresponding target triggering operation can be made based on the recognizable special effect in the special effect editing effect.
Specifically, after the user selects the special effect editing effect, the terminal device displays the background environment of the special effect editing effect on the capturing interface in response that the triggering operation acting on the special effect editing button, i.e., the first triggering operation. When the user clicks the capturing button to start capturing, an instruction for instructing to perform the capturing operation on the capturing interface is generated, and the terminal device receives the instruction and starts the capturing operation, i.e., the first capturing operation. In the capturing procedure, it is detected whether a target triggering operation (for example, an interactive action and/or a target object such as smiling, waving or a target building) exists in the captured video in real time. If existing, the client in the terminal device will send a speed change recording message corresponding to the target triggering operation to an audio and video terminal in the terminal device for speed change recording and saving of the current music.
S103: obtain a target video according to the captured video image and the audio.
S104: play, in the target video, a video image captured before the target object presents the target state at a constant speed, and play, in the target video, a video image captured after the target object presents the target state at a changing speed according to a second speed change mode, where the audio is played at a constant speed; where a speed change direction of the first speed change mode is opposite from a speed change direction of the second speed change mode and a changing speed of the first speed change mode is the same as a changing speed of the second speed change mode.
In this embodiment, the captured video image and audio are synthesized to obtain the audio and video to be played, i.e., the target video. Then, after the capturing is complete, the terminal device plays the target video. In the process of playing the target video, the video image captured before the target object presents the target state is played at a constant speed and the video image captured after the target object presents the target state is played at a changing speed according to the second speed change mode, while the audio is played at a constant speed.
The constant speed of the video herein refers to the capturing speed, and the constant speed of the audio refers to its own speed. Here, the speed change direction the second speed change mode is opposite to the speed change direction of the first speed change mode. For example, if the first speed change mode is 2x slow, the second speed change mode is 2x fast. The purpose may be to play the music at a normal speed when the target video is played after the capturing is complete, so as to improve the user’s viewing experience. In order to ensure that the audio played during playing after the capturing is complete is not interfered by the original sound played/or appeared randomly before the speed change recording, the captured original sound is not recorded during the audio processing.
In a possible design, the target state has a mapping relationship with the first speed change mode; or, the second speed change mode is determined in response to a setting operation of a user, and the first speed change mode is determined based on the second speed change mode.
In this embodiment, in view of the mapping relationship between the target state and the first speed change mode, it may be that the special effect editing effect itself defaults to the type and/or the speed of the speed change, therefore, the target state recognized by the special effect editing effect can determine its corresponding speed change type and/or speed. It is also possible to recognize a special effect through the special effect editing effect, and different actions in special effects trigger different types of speed changes, or even different speed changes, so as to determine the type and/or the speed of the speed change by the target state.
How to play an unplayed part of the audio at a changing speed according to a first speed change mode in response to recognizing that a target object presents a target state in a captured video image can be realized by the following steps.
Step b1: determine the first speed change mode having the mapping relationship with the target state in response to recognizing that the target object presents the target state in the captured video image.
Step b2: play the first part of the audio at a changing speed according to the first speed change mode.
In this embodiment, in response the recognized target state, the first speed change mode matching the target state is obtained through the mapping relationship, and then the first part of the audio is played at a changing speed based on the first speed change mode.
Since the second speed change mode is determined in response to a setting operation of a user, and the first speed change mode is determined based on the second speed change mode, the first speed change mode may be determined through the user by pushing a slider to set different speeds and selecting different types of speed changes through buttons. Here, there is no specific limitation on that how the user selects or sets different speed change modes, and the speed change mode includes a type of the speed change and/or a speed of the speed change.
Specifically, the second speed change mode can be a speed change mode required by the special effect, for example, if the speed change mode required by the special effect is 2x slow playback, the first speed change mode is 2x fast playback, and the second speed change mode is 2x slow playback; and can also be a mode input by the user. Specifically, after the capturing is complete, it jumps to display the playing interface, the video after speed change processing (i.e., the target video) is played through the playing interface, where the target video here includes a video image captured before the target object presents the target state and speed changing is performed, the video image captured after the target object presents the target state and played according to the second speed change mode and the audio played at a constant speed. Where the video image played according to the second speed change mode can be processed by adding or subtracting a frame.
In addition, when the capturing function is turned on, the terminal device starts capturing the target object and plays the currently captured video, where the played content here includes the video image upon capturing the target object and the music played in the capturing procedure. Until the speed change is triggered, the speed change processing starts, and the first part of the audio is played at a changing speed according to the first speed change mode, where the first part of the audio here represents an unplayed part of the audio when it is recognized that the target object presents the target state in the captured video image. Where the starting time of the first part of the audio is a time when the capturing interface captures the target object (i.e., a time when the speed change processing is started) in response to recognizing that the target object presents the target state in the captured video image; and the termination time of the first part of the audio is a time in response that the capturing is complete, which can be triggered by the user or a time of arrival of the capturing time. For example, when the start time of the first part of the audio is the capturing start time, it means that the target state is immediately detected when the capturing function is started, therefore, the video image played after the capturing is complete is a video image with speed change at the beginning.
Please refer to
In the embodiments of the present disclosure, in the capturing procedure, the user can click an ending capturing button 107 (see (a) of
Taking the smile action as the target triggering operation (i.e. the target state), and the smiling action to represent a 2x slow recording triggering action as an example, the special effect editing effect corresponding to the smile action is first added, and the music can also be selected or the background music of the special effect editing effect corresponding to the smile action can be taken as the captured music, and the terminal device starts to detect the target triggering operation. Specifically, it is determined whether there is a smile action, if there is a smile action, it is determined whether the current smile action occurs in the capturing, if the current smile action occurs in the capturing, it is determined whether the speed change state is triggered, if so, a message corresponding to the rate required by the smile action, i.e., the message recorded at 2x slow speed, is sent to the audio and video terminal VE, and the VE perform a fast recording and saving on the default music (the music currently played on the capturing interface), the fast recording here can be recorded at 2x fast speed. At the same time, the original sound is not recorded, and then the recorded target audio is sent to the client, and the client plays the target audio at a 2x slow speed, which shortens the total time, and ends the recording and playing.
According to the present disclosure, the capturing speed can be controlled only by smiling at the camera without the user operating the screen. At the same time, there is no need to import the captured video into other editing pages or software, the processing procedure is simple, and the user experience is improved. It should be noted that smile recognition is taken as an example to clearly explain the triggering and processing procedure of speed change recording, but the present disclosure does not limit interactive behavior, including raising a hand, gagging, shaking one’s head, etc.
The video processing method provided by the embodiments of the present disclosure allow for: playing an audio in a process of capturing a video, then playing a first part of the audio at a changing speed according to a first speed change mode in response to recognizing that a target object presents a target state in a captured video image, where the first part here represents an unplayed part of the audio when it is recognized that the target object presents the target state in the captured video image; then obtaining a target video according to the captured video image and the audio, playing, in the target video, a video image captured before the target object presents the target state at a constant speed, and playing, in the target video, a video image captured after the target object presents the target state at a changing speed according to a second speed change mode, where the audio is played at a constant speed, and where a speed change direction of the first speed change mode is opposite from a speed change direction of the second speed change mode and a changing speed of the first speed change mode is the same as a changing speed of the second speed change mode. Therefore, it is ensured that the audio is played at a constant speed in the target video, while a part of the video image is played at a constant speed and another part of the video image is played at a changing speed, thereby realizing the speed change recording and playing of the captured video. The present application can start the operation of controlling the video speed change recording directly by recognizing the target state presented by the target object, without the need to import the captured video into the video editing software or the editing page for a corresponding slow playback process or a fast playback process. In order to improve the user experience and make a user have a strong perception for the speed change recording, after the speed change recording is triggered in the video capturing process, the played audio is played at a changing speed according to the first speed change mode, while in the process of playing the target video generated after capturing, for the video captured after the speed change is triggered, the video image is played at a changing speed according to the second speed change mode, while the audio is played at a constant speed. Thus, the personalized needs of users are satisfied, and the processing procedure is simple and the operation steps are simplified, causing the user to realize the speed change processing of the video through convenient operation, thereby improving the user experience.
In an embodiment of the present disclosure, on the basis of the above embodiments, the target video can be obtained at least by the following two modes.
Mode 1: synthesize the video image after performing a speed change processing and the audio played at a constant speed as a target video.
Step c1: record the captured video image at a constant speed to obtain a first video.
Step c2: divide the first video into a first video segment and a second video segment; the first video segment represents a segment of the first video before the target object presents the target state; and the second video segment represents a segment of the second video after the target object presents the target state.
Step c3: perform speed change processing on the second video segment according to the second speed change mode to obtain a third video segment.
Step c4: synthesize the audio in a spliced video of the first video segment and the third video segment to obtain the target video.
In this embodiment, firstly, the captured video image is recorded at a constant speed to obtain the first video, and then the first video is divided into a segment (i.e., the first video segment) before the target object presents the target state and a segment (i.e., the second video segment) after the target object presents the target state. The first video segment is saved unchanged, and for the second video segment, the second video segment is processed by adding or subtracting a frame according to a second speed change mode, to obtain a third video segment, where the third video segment is a video image after speed change processing. Then the saved first video segment is spliced with the third video segment obtained by speed change processing to obtain a spliced video, and the audio recorded and saved at a normal speed is synthesized with the spliced video to obtain a target video. Since it is background processing, rather than real-time processing, the speed change processing that differs from speed change processing with the duration in prior art can be supported and the operation is simple without importing other editing software, thus improving the user experience.
Mode 2: splice the video image after speed change processing with the audio after speed change processing to generate the target video.
Step d1: record a played video image and a played audio to obtain a second video in the process of capturing a video; and in the second video, play the audio before the target object presents the target state at a constant speed, and play the audio after the target object presents the target state at a changing speed according to a first speed change mode, where the captured video image is played at a constant speed.
Step d2: divide the second video into a third video segment and a fourth video segment; where the third video segment represents a segment of the second video before the target object presents the target state; and the fourth video segment represents a segment of the second video after the target object presents the target state.
Step d3: perform speed change processing on the fourth video segment according to the second speed change mode to obtain a fifth video segment; and splice the third video segment and the fifth video segment to obtain the target video.
In this embodiment, in the process of capturing a video, the played video image and audio are recorded to obtain the second video, and the recorded audio before the target object presents the target state is played at a constant speed, the recorded audio after the target object presents the target state is played at a changing speed according to the first speed change mode, and the recorded video image is played at a constant speed. Where the second video is divided into a segment (i.e., the third video segment) before the target object presents the target state and a segment (i.e., the fourth video segment) after the target object presents the target state.
Specifically, the third video segment is saved, and speed change processing is performed on the fourth video segment according to second speed change mode, i.e., the image video in the fourth video segment is processed by adding or subtracting a frame, and the audio in the fourth video segment (i.e., the audio played at a changing speed based on first speed change mode and recorded) is played in a second speed change mode, such that the audio is played at a constant speed. Splice the saved third video segment with the speed change processed fifth video segment to obtain the target video. Since it is background processing, rather than real-time processing, the speed change processing that differs from speed change processing with the duration in prior art can be supported and the operation is simple without importing other editing software, thus improving the user experience.
In order to ensure the normal speed of the audio played through the first speed change mode, the second speed change mode with the opposite speed change direction and the same speed as those of the first speed change mode can be recorded first to obtain the audio processed by the first speed change mode. For example, if the first speed change is a 2x slow speed, the second speed change is a 2x fast speed. Then the audio processed by the first speed change mode is subjected to speed change processing according to the second speed change mode to obtain the audio played at normal speed, i.e., the audio played in the target video.
Specifically, the terminal device acquires the currently played target music when the speed change recording is triggered in the capturing process, and then performs speed change recording on the audio after presenting the target state according to the determined second speed change mode, so as to generate the speed change audio which does not contain the original sound upon capturing in the capturing interface.
The starting time of the audio recorded by the first speed change mode is a time when the target state is presented in response to the recognition (i.e., a time when the target state is presented in response to the recognized target object); and the ending time of the audio recorded by the first speed change mode is a time corresponding to the progress of playing music when the capturing interface captures the target object at the end of capturing (i.e., a time when the speed change recording is complete).
The rate of the speed change includes slow speed, fast speed and normal speed, and the speed is any value between 0.333-3, and the speed change can be represented by speed multiplying power. Exemplarily, taking the first speed change as 2x slow speed as an example, for example, the video image recorded at the normal speed is 30 frames/s, according to the rate of the 2x slow speed, the corresponding subtracted frame operation is carried out on the video image, for example, the recorded video image is recorded at 2 s for 30 frames, so that the playing rate of each frame of video image becomes slower upon playing.
In an embodiment of the present disclosure, based on the above embodiments, after the capturing function is turned on, the video processing method may further include:
In the embodiments of the present disclosure, the user can click an ending button used to indicate the end of capturing in the capturing interface. When the terminal device detects the triggering operation acting on the end button, i.e., the second triggering operation, in response to the second triggering operation, the terminal device sends a message of resetting the recording speed, controls the VE to reset state and the client to reset state, and then updates the capturing state. Specifically, the first speed change mode and/or the second speed change mode and/or the state of the special effect editing effect and/or the state of the capturing interface are reset.
Specifically, the specific procedure of the user clicking start capturing/stop special effect editing effect is as follows: the terminal device first judges whether the capturing is started, if the capturing is started, updates the capturing state and end the started capturing state; and if the capturing is not started, judges whether the capturing is ended. If the capturing is ended, a message resetting the recording speed is sent to control the VE to reset state and the client to reset state, so as to update the capturing state and end the capturing state.
In an embodiment of the present disclosure, based on the above embodiments, the video processing method is explained in detail. After jumping to display the playing interface, the video processing method can also be realized by the following steps.
Step e1: control the playing interface to return to the capturing interface containing a captured target object in response to a first return triggering operation.
Step e2: if an instruction to indicate a recapture is received, reset the content of the capturing interface containing the captured target object and exit the capturing interface according to the instructions for indicating a recapture.
In the embodiments of the present disclosure, after jumping to display the playing interface, the recorded video, i.e., the target video, is played on the display interface. When the user wants to return to the capturing interface for re-editing, re-capturing or continuous capturing, the user can click the first return button on the display interface, in response to the first return triggering operation acting on the first return button, the terminal device controls the playing interface to return to the capturing interface containing the captured target object, i.e., jumps to display the capturing interface in a pause capturing state. The user can choose to cancel the current capturing content in the current capturing interface, i.e., the user can click the second back button on the current capturing interface, generate an instruction for re-capturing, and send the instruction to the terminal device, the terminal device receives the instruction, resets the content of the capturing interface and exits the current capturing interface according to the instruction. It is convenient for the user to re-capture, and the interactive operation is simple.
In an embodiment of the present disclosure, based on the above embodiments, the video processing method is explained in detail. The video processing method may further include the following steps.
Step f1: after controlling the playing interface to return to the capturing interface containing a captured target object or when the capturing interface receives an instruction to suspend capturing upon capturing the target object in the capturing interface, detect whether to the progress bar of capturing time on the current capturing interface reaches the ending position.
Step f2: if the ending position is not reached, when an instruction for instructing to perform the capturing operation on the capturing interface is received, control to continue performing the capturing operation on the capturing interface.
In the embodiments of the present disclosure, if the capturing time in the capturing interface is not over yet, the user can continue capturing in the current capturing interface immediately after the original capturing content. It can be realized by at least two scenarios as follows.
Scenario 1: the current interface is in the playing interface, and the user can click the first return button in the playing interface to make the terminal device to return the playing interface to the capturing interface in the pause capturing state. In this state, the progress bar of the capturing time is displayed on the capturing interface, and whether capturing can be continued is determined by detecting whether the progress bar of the capturing time on the capturing interface reaches the ending position. If the ending position is not reached, the user can click the capturing button on the capturing interface in this state, and the terminal device receives an instruction for instructing to perform capturing operation on the capturing interface, and continues performing the capturing operation on the capturing interface according to the instruction.
Scenario 2: the current interface is in the capturing interface, and the capturing interface is in the capturing pause state in response to the instruction input by the user to indicate a capturing pause. In this state, the progress bar of the capturing time is displayed on the capturing interface, and whether capturing can be continued is determined by detecting whether the progress bar of the capturing time on the capturing interface, in this state, reaches the ending position. If the ending position is not reached, the user can click the capturing button on the capturing interface in this state, and the terminal device receives an instruction for instructing to perform capturing operation on the capturing interface, and continues performing capturing operation on the capturing interface according to the instruction.
Thus, the present disclosure aims to reduce the threshold for the user to capture a “slow-motion transformation” class of video, to cause the user to record the slow-motion video more than 1 s or record fast motion through special effect editing effect, and solve the problem of a music and image mismatch, meanwhile in a special effect package, a logic to “recognize a certain triggering condition, and allow the recording to change a speed” is added, and the speed change playing event is passed to the audio and video terminal and the client in real time by the special effect to perform speed change recording in the audio and video terminal, enabling the user to more simply produce a higher quality slow-motion video or a higher quality fast-motion video, thus improving the user experience.
The capturing module 701, the processing module 702, and the playing module 703 provided by the embodiments of the present disclosure play the video in the process of capturing a video, then play a first part of the audio at a changing speed according to a first speed change mode in response to recognizing that a target object presents a target state in a captured video image, where the first part here represents an unplayed part of the audio when it is recognized that the target object presents the target state in the captured video image; then obtain a target video according to the captured video image and the audio, play, in the target video, a video image captured before the target object presents the target state at a constant speed, and play, in the target video, a video image captured after the target object presents the target state at a changing speed according to a second speed change mode, where the audio is played at a constant speed, and where a speed change direction of the first speed change mode is opposite from a speed change direction of the second speed change mode and a changing speed of the first speed change mode is the same as a changing speed of the second speed change mode. Therefore, it is ensured that the audio is played at a constant speed in the target video, while a part of the video image is played at a constant speed and another part of the video image is played at a changing speed, thereby realizing the speed change recording and playing of the captured video. The present application can start the operation of controlling the video speed change recording directly by recognizing the target state presented by the target object, without the need to import the captured video into the video editing software or the editing page for a corresponding slow playback process or a fast playback process. In order to improve the user experience and make a user have a strong perception for the speed change recording, after the speed change recording is triggered in the video capturing process, the played audio is played at a changing speed according to the first speed change mode, while in the process of playing the target video generated after capturing, for the video captured after the speed change is triggered, the video image is played at a changing speed according to the second speed change mode, while the audio is played at a constant speed. Thus, the personalized needs of users are satisfied, and the processing procedure is simple and the operation steps are simplified, causing the user to realize the speed change processing of the video through convenient operation, thereby improving the user experience.
