Fig. 1 is a flowchart of a video editing method according to an embodiment of the present application, as shown in fig. 1, the method including:
step 101, a video editing request is obtained, wherein the editing request includes first video data to be edited.
The first video data to be edited may be shot by the user in real time, or may be selected by the user from the shot videos, or downloaded by the video platform.
it should be noted that, in different application scenarios, the manner of obtaining the video editing request is different, and the following example is illustrated:
The first example:
In this example, the video editing request is sent in a voice manner.
specifically, after a user selects first video data, voice data of the user is collected through pickup equipment, and when keywords such as "edit video" are recognized in the collected voice data of the user, a video editing request for the selected first video data is acquired.
the second example is:
In this example, the user sends the video editing request in the form of an action.
specifically, after the user selects the first video data, a gesture action or a facial expression action of the user is collected through a camera or a touch screen, and the like, the collected action is matched with a preset action, and if the matching is successful, an editing request of the user for the first video data is obtained.
Of course, in this example, the manner in which the user selects the first video data may also be determined according to the motion, and is not described herein again.
The third example:
In this example, as shown in fig. 2, a selection control, an editing menu, and the like are provided on the video interface, and the user may trigger the selection control of the first video data to select the first video data, and further, the sending of the video editing request is realized by triggering the editing menu.
And 102, playing first video data in a first layer of a preset canvas.
It should be appreciated that in the present embodiment, a visual editing interface for video editing is provided that provides a preset canvas on which visual editing of video occurs.
specifically, in order to facilitate the user to edit the first video data, the first video data is played in the first layer of the preset canvas, so that the user can perform corresponding personalized editing according to the content of the first video data.
step 103, acquiring a video editing instruction, wherein the editing instruction comprises a target editing mode.
And 104, generating an editing picture in a second layer of the preset canvas according to the target editing mode, wherein the second layer is positioned on the upper layer of the first layer, and the second layer is a transparent layer.
Specifically, when the first video data is played, a video editing instruction is obtained, where the video editing instruction includes a target editing mode, and the target editing mode corresponds to specific editing contents of the video, such as text addition (format of text, and the like), animation addition, special effect addition (addition of particle effect such as fireworks, and the like), color change, filter addition energy, and the like, where different target editing modes may be combined, such as the text addition and animation addition modes, and an effect of continuously turning text left and right may be achieved.
Furthermore, according to the target editing mode, an editing picture is generated in a second layer of the preset canvas, where the second layer is located on an upper layer of the first layer, the second layer is a transparent layer, and a transparency of the second layer may be set according to a display requirement of a user, and if the user wants to display an effect that a picture content included in the first layer is relatively blurred, that is, the transparency may be relatively low, otherwise, the transparency may be relatively high, so that, in the preset canvas, the video picture in the first layer and the editing picture in the second layer may be displayed, for example, as shown in fig. 3, when the editing picture in the second layer is a character, the character and the video picture may be displayed together.
It should be noted that, in different application scenarios, the manner of triggering the video editing instruction by the user is different, and the following example is illustrated:
The first example:
In the present example, the video editing instruction is triggered in a voice manner, and a corresponding video editing instruction is determined based on the voice data of the user through keyword or semantic recognition.
the second example is:
In this example, an editing tool, such as a character editing tool, a special effect editing tool, and the like, is displayed in a preset canvas, and an editing frame corresponding to a selected target tool is generated in the second layer according to a selection instruction of a user for an editing work, for example, when the user selects the character editing tool, the corresponding character editing frame may be displayed in the second layer, a specific editing operation instruction manually input by a user may be received in the editing frame, the editing frame may also include a plurality of editing operation controls, and based on the selection of the operation controls by the user, the specific editing operation instruction may be determined, so that a target editing mode is determined according to the obtained editing frame operation instruction.
in actual execution, there may be a plurality of editing operation instructions of a user, for example, the user has an editing operation instruction for adding a plurality of animation special effects, so as to avoid that editing effects corresponding to different editing operation instructions conflict with each other and are difficult to display comprehensively, target editing modes corresponding to different editing operation instructions may be displayed in different layers, and conflict of editing effects corresponding to editing operations is avoided between different layers according to the distinction of the transparency.
Specifically, the preset canvas includes N editing tools, and N editing frames of the N editing tools correspond to M layers, where M is a positive integer less than or equal to N, transparency of the M layers is set to be different, and division of transparency of different layers may be determined according to an order of the layers, for example, transparency of a layer above the layer is higher, and division may also be performed according to priority of a corresponding editing operation instruction in the layer, for example, transparency of a layer corresponding to an editing operation instruction with higher priority is lower.
And 105, intercepting a picture displayed in a preset canvas according to a first preset time interval.
It can be understood that, in this embodiment, the picture displayed in the preset canvas is periodically captured according to the first preset time interval, so that the edited picture can be obtained in time.
As a possible implementation manner, a screenshot instruction may be sent to the graphics processor at a first preset time interval, the specified sending mode may be a voice trigger or a screenshot control trigger, and the like, and after receiving the screenshot instruction, the graphics processor captures a picture from a preset canvas at the first preset time interval and returns the captured picture to a corresponding picture. It should be noted that, in the present embodiment, the editing picture is generated according to the image processor, so that the problem of frame dropping of the first video playing data can be avoided.
The first preset time interval may be fixedly calibrated according to experimental data, and in order to ensure the integrity of captured images, the first preset time interval may also be set according to the play speed of the first video data, for example, if 24 frames of images are displayed per second, the corresponding first preset time interval is 1/24 s. When the playing speed of the first video data changes in real time, the first preset time interval may also change in real time.
However, when the screenshot is derived, the speed of storing the video frame is usually slower than the screenshot speed, and if the screenshot speed is not slowed down, the cached screenshot frames may be more and more, and finally, the memory may be overflowed.
Therefore, in an embodiment of the present application, the editing frame and the first video data may also be controlled to play at a preset rate, where the preset rate is smaller than an original playing rate of the first video data, that is, when the editing frame is exported, the playing rates of the video and the corresponding video editing frame are synchronously slowed down, for example, the preset rate is changed to one third of the original playing rate, thereby facilitating a screenshot operation of the editing frame. And then, pictures displayed in the preset canvas are intercepted according to a second preset time interval, wherein the second preset time interval is longer than the first preset time interval, the second preset time interval can be determined according to the storage speed, and every frame of picture is deleted in the cache, so that the memory overflow is avoided.
as a possible implementation manner, the original playing rate of the first video data is V1, the preset rate is V2, and the first preset time interval is t1, and the second preset time interval may be calculated according to the following formula (1). Thereby, it is ensured that the second predetermined time interval is obviously longer than the first predetermined time interval.
Of course, in an embodiment of the present invention, the time when the user edits the screen may also be determined, and the screenshot operation is performed only within the playing time corresponding to the editing screen at the time. Interception of video frames where the user does not edit the frame is avoided. Further meeting the personalized requirements of users.
And 106, sequentially synthesizing the pictures according to the capturing sequence of the pictures to generate edited second video data, wherein the playing time of each image in the second video data is a first preset time.
specifically, according to the capturing sequence of each picture, the pictures are sequentially subjected to synthesis processing, such as splicing processing, and the like, and edited second video data is generated, wherein the playing time of each image in the second video data is a first preset time, so that whether the playing rate of the first video data and the edited picture is slowed down in the process of exporting the picture or not, the original playing rate is still played in the second video data, and the playing effect is not affected.
For example, if the first preset time interval is x, and the first preset time interval is the same as the original playing speed (the switching time interval of each frame of picture), the playing speed of the first original video data may be changed to x/3 when the video is derived, wherein the playing speed of the edited picture is also displayed according to x/3, and further, the screenshot is performed according to the x/3 time interval, but finally the second video data is synthesized according to the time interval of x, although the playing and synthesizing time is slow. But the composite video is played at normal speed, so that the playing speed of the finally derived video is normal.
Considering that in some application scenarios, a user has a cropping requirement for a corresponding picture when editing the first video data, for example, the user only wants to keep a part of a character image in the picture, etc., in order to meet the personalized requirement of the user, in one embodiment of the present invention, the cropping instruction of the user is responded.
In this embodiment, the preset canvas includes a first area and a second area, wherein the number of the first area and the second area can be arbitrarily set, the first area is a transparent area, the second area is a non-transparent area, and the display priority of the second area is higher than that of the first area, that is, when the picture in the canvas moves from the first area to the second area, the non-transparent picture of the second area is displayed instead of the corresponding picture, before the picture displayed in the preset canvas is intercepted, if the cutting instruction is obtained, the distribution mode of the first area and the second area in the preset canvas is adjusted according to the cutting area in the cutting instruction, i.e. the area outside the cropped area in the first area is covered by the second area, so that, on subsequent screenshots, the picture in the second area is not displayed any more, and the cutting operation of the related picture is realized.
The triggering mode of the cutting instruction can be implemented through a touch screen action track or through a selection operation of transferring a cutting area selection tool. The cutting area may be any shape such as a circle, a square, etc., which is not exemplified herein.
In addition, in different application scenes, the distribution modes of the first area and the second area in the preset canvas are adjusted to be different according to the clipping area in the clipping instruction, as a possible implementation mode, when the number and the distribution modes of the second area and the first area are as shown in fig. 4, the moving operation of a user on the picture in the first area can be received, when the user moves the display picture lower than the area left and right, the display picture can be clipped, and all the display pictures shielded by the second area are equal to the clipped display pictures.
As another possible implementation manner, when the number and the distribution manner of the second areas and the first areas are as shown in fig. 5, the second areas can be covered in the corresponding screens of the first areas through a drag operation on the second areas, and all the display screens blocked by the second areas are equivalently cropped.
Therefore, according to the embodiment, the video is edited according to the visualization operation in the preset canvas, the synthesized second video data can be used for recording life fragments, dynamically publishing in social software, applying dynamic wallpaper and the like, and the video editing operation does not depend on the learning and integration of codes any more.
