When a user wants to merge two videos, the terminal can be operated to start a video clip application program, the two videos are spliced in the video clip application program, and the effect of video transition is added between the two videos, so that the merged video is obtained. In the process of video merging, a user can preview a video transition effect in an interface of a video clip application program, and a player installed in a terminal judges whether to make a transition or not according to a current timestamp of a video in a playing time period in the transition preview process, wherein the current timestamp is a time point corresponding to the current time when the video is played in the playing time period. Fig. 3 is a flowchart of a video transition method according to an embodiment of the present application. The terminal and the server may both be referred to as a computer device, and this embodiment is described with the computer device as an execution subject, referring to fig. 3, and this embodiment includes:

in step 301, a computer device obtains a first transition period for a first video trailer and a second transition period for a second video trailer.

In this embodiment of the application, the first video and the second video are videos to be merged, the first video may be a video with a previous playing sequence set by the user, and the second video may be a video with a next playing sequence set by the user. The first transition time period is a time period for video transition of the first video, and the second transition time period is a time period for video transition of the second video. The first video and the second video are two videos in adjacent playing sequence, and no other video exists between the first video and the second video.

In a possible implementation manner, the process of the computer device acquiring the first transition time period includes: after the computer equipment acquires the preset transition time period between the videos, acquiring the time period occupied by the preset transition time period at the end of the first video according to the playing sequence of the first video and the second video, and taking the time period as the first transition time period. The process of acquiring the second transition time period by the computer device includes: after the computer equipment acquires the preset transition time period between the videos, the time period occupied by the preset transition time period at the leader of the second video is acquired as the second transition time period according to the playing sequence of the first video and the second video.

Specifically, when a user wants to add a transition effect between two videos, the computer device may be operated to start the video clip application, and then the video clip application has tags such as a video tag, an audio tag, a transition special effect, and an overlay material displayed in an interface thereof. The user can click the transition special effect label, the added video label and the video time axis are displayed in the interface of the video clip application program, the user can operate the computer equipment to import the first video, the first video is displayed in the interface and imported to the video time axis, then the second video is imported, and the second video is located at the position, behind the first video, on the video time axis. The user can operate the computer device to click the transition time tag, manually set the total duration of the transition time period, or select the total duration of the default transition time period. After a user sets the transition time period duration, a transition time period is displayed on a video time axis in the interface, and the transition time period covers a part of time period of the first video title and covers a part of time period of the second video title. The computer device may use a time period occupied by the transition time period at the end of the first video as a first transition time period of the first video, and use a time period occupied by the transition time period at the head of the second video as a second transition time period of the second video.

For example, assuming that the duration of the first video is 2s and the duration of the second video is 3s, after the user imports the first video and the second video, a transition time period with a total duration of 300ms may be preset, and then the duration of the transition time period in the time period occupied by the first video end is 150ms, and then the first transition time period of the first video is 1.850s to 2 s. The duration of the transition time period in the time period occupied by the second video leader is 150ms, and then the second transition time period of the second video is 2s to 2.150 s.

In one possible implementation, the process of the computer device acquiring the first video and the second video may be: the computer device may select two videos from the locally stored historical videos, with one video being a first video and the other video being a second video. Or, the computer device may also use the camera to shoot two videos on site, and use one of the shot videos as a first video and another video as a second video, which is not limited in how to obtain the videos in this embodiment of the present application, and it should be noted that, in this embodiment of the present application, only transition between two videos that are adjacent in the playing sequence is taken as an example for description, in some embodiments, transition between multiple videos may also be set at the same time, so that transition between multiple videos can be previewed during previewing, and a transition processing process between every two videos that are adjacent in the playing sequence may use the flow of this embodiment of the present application, which is not described herein again.

In step 302, the computer device determines at least one first image for a first transition period of the first video based on at least one original image for the first transition period, and determines at least one second image for a second transition period of the second video based on at least one original image for the second transition period.

In the embodiment of the application, at least one first image is obtained by stretching at least one original image in a first transition time period based on the first video. The at least one second image is stretched based on the at least one original image during a second transition period of the second video.

In one possible implementation, the process of the computer device determining the first image may include: the computer device can acquire at least one original image in a first transition time period of the first video, and stretch the height and the width of the at least one original image by a target multiple to obtain at least one first image in the first transition time period. The process of the computer device determining the second image may include: the computer device may acquire at least one original image in a second transition time period of the second video, and stretch the height and the width of the at least one original image by a target multiple to obtain at least one second image in the second transition time period. The target multiple is an adjustable parameter, and represents that one image needs to be completely displayed through several video frames in the transition time period.

Specifically, when the computer device determines the first image, after the computer device acquires the first transition time period of the first video, the computer device may acquire at least one original image in the first transition time period of the first video, stretch each original image by the target multiple with the original image having the same height and the same width, obtain an image with the target multiple stretched, use the image as the first image of the first video, and further obtain at least one first image in the first transition time period. When the computer device determines the second image, after the computer device acquires the second transition time period of the second video, the computer device may acquire at least one original image in the second transition time period of the second video, stretch the height and the width of each original image by the target multiple to obtain an image with the target multiple stretched, and use the image as the second image of the second video to further obtain at least one second image in the second transition time period.

For example, according to the above example, the first transition time period of the first video may be 1.850s to 2s, and when the target multiple is 2, the computer device may acquire at least one original image of the first video for the time period of 1.850s to 2 s. And stretching the at least one original image by 2 times with the same height to obtain an image stretched by 2 times, and taking the image as a first image of the first video to further obtain at least one first image of the first video in the range from 1.850s to 2 s. The second transition period of the second video may be 2s to 2.150s, and when the target multiple is 2, the computer device may acquire at least one original image of the second video for a period of 1.850s to 2 s. And stretching the at least one original image by 2 times with the same height to obtain an image stretched by 2 times, and taking the image as a second image of the second video to further obtain at least one second image of the second video in the range of 1.850s to 2 s.

In step 303, when the first video is played to the first transition time period, the computer device sequentially displays, according to the first playing progress of the first video, image portions corresponding to the first playing progress in the at least one first image.

In this embodiment of the application, the first playing progress refers to a playing progress of a first image corresponding to a current time of a first video in a first transition time period. The value range of the progress (progress, upload progress bar) is [0,1], the first transition time period of the first video is 1.850s to 2s in the above example, the corresponding progress is 0 when the current timestamp is 1.850s, and the corresponding progress is 1 when the current timestamp is 2 s.

In one possible implementation, the process of displaying at least one first image of the first video by the computer device may be: the computer equipment acquires at least one first image in a first transition time period, and when the first video is played to the first transition time period, image parts corresponding to a first playing progress in the at least one first image in the first transition time period are sequentially displayed according to the first playing progress of the first video.

Specifically, when the first video is played to the first transition time period, the first playing progress of the first video may be determined according to the current time value of the first video in the first transition time period, the initial time value of the first transition time period, the total duration of the first transition time period, and the progress formula (1).

Wherein K is progress, T₂For the current time value, T₁Is the initial time value, and T is the total time length. According to the first playing progress, an image part corresponding to the first playing progress in the at least one first image can be determined, and in the first transition time period, the image part corresponding to the first playing progress in the at least one first image is sequentially displayed according to the first playing progress.

For example, when the first transition time period of the first video is 1.850s to 2s and the current timestamp is 1.850s, the first playing progress is 0, the first image corresponding to the initial time value of the first transition time period of the first video starts to be displayed, and the image portions corresponding to the first playing progress in the at least one first image are sequentially displayed from left to right according to the first playing progress. When the current timestamp is 2s, the first playing progress is 1, and the display of each first image of the first video in the first transition time period is completed, so that the transition effect of moving from right to left is simulated.

In step 304, after the first video is played, the computer device sequentially displays image portions corresponding to the second playing progress in the at least one second image according to the second playing progress of the second video.

In this embodiment of the application, the second playing progress refers to a playing progress of a second image corresponding to a current time of a second video in a second transition time period.

In one possible implementation, the process of displaying at least one second image of the second video by the computer device may be: after the first video is played, the computer device may acquire at least one second image in a second transition time period, and sequentially display an image portion corresponding to a second playing progress in the at least one second image in the second transition time period according to the second playing progress of the second video.

Specifically, after the first video is played, the second playing progress of the second video may be determined according to the current time value of the second video in the second transition time period, the initial time value of the second transition time period, the total duration of the second transition time period, and the progress formula (1). And according to the second playing progress, determining an image part corresponding to the second playing progress in the at least one second image, and sequentially displaying the image part corresponding to the second playing progress in the at least one second image according to the second playing progress in the second transition time period.

For example, when the second transition time period of the second video is 2s to 2.150s and the current timestamp is 2s, the second playing progress is 0, the second image corresponding to the initial time value starts to be displayed, and the image portions corresponding to the second playing progress in the at least one second image are sequentially displayed from left to right according to the second playing progress. When the current timestamp is 2.150s, the second playing progress is 1, and the display of each second image of the second video in the second transition time period is completed, so that the transition effect of the second video entering the screen from the right side is simulated.

In a specific example, fig. 8 is a schematic diagram of image stretching according to an embodiment of the present application, and as shown in fig. 8, an original image of a first video may be a letter a, an original image of a second video may be a letter B, a height of the original image is unchanged, a width of the original image is stretched by 2 times, an image with a width enlarged by 2 times is obtained, and widths of the letters a and B are both enlarged by 2 times. When the total duration of the transition time period is 4 frames, the duration of the first transition time period of the first video is 2 frames, the progress of the first frame is 0.5, the left half of the letter a of the first video is displayed, the progress of the second frame is 1, the right half of the letter a of the first video is displayed, and the progress from 0 to 1 is just right for completely displaying the first video, that is, completely displaying the letter a. The duration of the second transition time period of the second video is also 2 frames, and the display process of the second video is the same as that of the first video, and is not repeated.

All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present application, and are not described herein again.

In the above steps 301 to 305, taking an example that at least one first image in the first transition time period is obtained first, and when the first video is played to the first transition time period, the at least one first image is directly used for explanation, in this embodiment of the application, the computer device may further determine at least one first image in the first transition time period when the first video is played to the first transition time period, so as to perform a subsequent display process. Fig. 4 is a flowchart of a video transition method according to an embodiment of the present application. Referring to fig. 4, the embodiment includes:

in step 401, the computer device obtains a first transition period of a first video trailer and a second transition period of a second video trailer.

Step 401 is similar to step 301, and will not be described herein again.
