Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

The video character adding method and apparatus of the embodiments of the present application are described below with reference to the accompanying drawings.

The execution main body of the video character adding method in the embodiment of the application can be equipment with an image processor, such as a mobile phone, a tablet computer, a personal digital assistant and wearable equipment, and the wearable equipment can be an intelligent bracelet, an intelligent watch and intelligent glasses.

Fig. 1 is a flowchart of a video character adding method according to an embodiment of the present application, as shown in fig. 1, the method including:

step 101, a video character adding request is obtained, wherein the adding request comprises a first video to be processed.

The first video to be processed may be shot by the user in real time, or may be selected by the user from among already shot videos, or downloaded by the video platform.

It should be noted that, in different application scenarios, the manner of obtaining the video character adding request is different, and the following example is illustrated:

the first example:

in this example, the user sends a video character addition request in speech.

Specifically, after a user selects a first video, voice data of the user is collected through the sound pickup device, and when keywords such as "video character addition" are recognized in the collected voice data of the user, a video character addition request for the selected first video is acquired.

The second example is:

in this example, the user sends a video character addition request in the form of an action.

Specifically, after a user selects a first video, a gesture action or a facial expression action of the user is collected through a camera or a touch screen, the collected action is matched with a preset action, and if the matching is successful, a video character adding request of the user for the first video is obtained.

Of course, in this example, the manner in which the user selects the first video may also be determined according to the motion, and is not described here again.

In this example, as shown in fig. 2, a selection control, a video character adding menu, and the like are provided on the video interface, and the user may trigger the selection control of the first video to select the first video, and further, the video character adding menu is triggered to implement sending of the video character adding request.

And 102, playing a first video in a first layer of a preset canvas playing area.

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, the first video is played in the first layer of the preset canvas, so that the user can perform corresponding personalized character addition editing according to the content of the first video.

Step 103, when the character input instruction is obtained, displaying a target character corresponding to the input instruction in a second layer of a preset canvas playing area, wherein the second layer is located on the upper layer of the first layer, and the second layer is a transparent layer.

Specifically, when a first video is played, a character input instruction is obtained, where the character input instruction includes a character, a size of the character, a color of the character, a dynamic effect of the character, and the like, and then a target character corresponding to the input instruction is displayed in a second layer of a preset canvas playing area, where the second layer is located on an upper layer of the first layer, and the second layer is a transparent layer, where 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, and thus, in a visual effect of the preset canvas, as shown in fig. 3-1, a video picture in the first layer and a character in the second layer may be displayed.

It should be noted that, in different application scenarios, the manner of the user triggering the character input instruction is different, and the following example is illustrated:

the first example:

in the present example, the user triggers the character input instruction in a voice manner, and the corresponding character input instruction is determined based on the voice data of the user through keyword or semantic recognition.

The second example is:

in this example, a character frame is displayed in the second layer of the preset canvas play area, and the focus of the display interface is moved into the character frame, so that a user may input a corresponding character input instruction in the character frame, for example, inputting characters such as "beautiful" and the like, or may also display character controls in a non-play area of the preset canvas, each character input control corresponds to a target character corresponding to a specific character input instruction, at this time, a style of the target character and the like are already defined in the character input controls, and based on a trigger operation on the corresponding displayed character control, the character input instruction is triggered, and the corresponding target character is determined.

Certainly, in order to further improve flexibility of character addition in the embodiment of the present application, a user may customize an added character, and after a target character corresponding to an input instruction is displayed in a second layer of a preset canvas play area, a character adjustment instruction may also be obtained, where the character adjustment instruction may be triggered by voice or triggered by a corresponding adjustment control triggered by the user, where the character adjustment instruction corresponds to adjustment of a position, a color, an animation special effect, and the like of the character, and after the character adjustment instruction is obtained, a display style of the target character may be adjusted according to the adjustment instruction, where the display style corresponds to the character adjustment instruction and includes adjustment of the position, the color, the animation special effect, and the like of the character.

For example, referring to fig. 3-2, after clicking the target character in the second layer, a text edit box appears, and at this time, the text that has been added may be enlarged, reduced, rotated, dragged, etc., or the character may be removed by clicking the "x" number.

And 104, intercepting the picture displayed in the preset canvas playing area according to a first preset time interval.

It should be emphasized that, in this embodiment, the displayed picture in the preset canvas playing area is intercepted, so that even if the first video is not full of the preset canvas, no irrelevant picture, such as other display elements in the canvas, is intercepted.

It can be understood that, in this embodiment, according to a first preset time interval, a picture displayed in a preset canvas play area is periodically captured, so that an 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 image 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.

Wherein the first predetermined time interval may be calibrated according to experimental data,

the calibration is fixed, 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, when 24 frames of images are displayed every 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 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, that is, when the editing frame is derived, 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 the screenshot operation of the editing frame. And then, pictures displayed in the playing area 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 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 application, a time at which 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 a video picture to which a user has no character addition is avoided. Further meeting the personalized requirements of users.

And 105, sequentially synthesizing the pictures according to the intercepting sequence of the pictures to generate a second video added with characters, wherein the playing time of each picture in the second video 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, to generate an edited second video, wherein the playing time of each picture in the second video data is the first preset time interval, so that whether the playing rate of the first video and the target character is slowed down or not in the deriving of the picture or not, the original playing rate is still played in the second video, and the playing effect is not affected.

For example, assuming that the first preset time interval is x, and the first preset time interval is the same as the original playing speed, 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 editing screen 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 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 a first video, 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 application, a region is divided in a preset canvas to crop the picture by the distribution of the region, specifically,

in this embodiment, the preset canvas includes a first area and a second area, where the number of the first area and the second area may 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, after a 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, after a target character corresponding to an input instruction is displayed in a second layer of a play area of the preset canvas, if a clipping instruction is obtained, a distribution manner of the first area and the second area in the preset canvas is adjusted according to the clipping area in the clipping instruction, that is, an area outside the clipping area in the first area is covered by the second area, so that, in a subsequent screenshot, a picture displayed in the first area is clipped, 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 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 of the first 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, character addition editing of the video is realized according to the visualization operation in the preset canvas, the synthesized second video 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 code learning and integration any more.
