Problems solved by technology

[0002] When splicing multiple video clips, transition processing is required at the junction of the videos; the current self-media transition processing in the video splicing process is relatively simple, mostly simple splicing or inserting videos, pictures, etc. It often leads to blunt, unnatural, and unsmooth connection of the pictures. At the same time, in order to ensure the integrity of the video content, some fragments that do not involve substantive content are often intercepted at the beginning and end of the editing process, thereby increasing redundant information and making the video smooth. The artistic expression is reduced and the viewing effect is affected; in addition, the operation of inserting clips also significantly increases the workload and time cost of video production; thus significantly affecting the efficiency of video processing

Embodiment 1

[0044] Such as figure 1 As shown, Embodiment 1 of the present invention provides a method for video transition special effects, comprising the following steps:

[0045] S1: Obtain at least two edited video clips as original clips, and sort the original clips;

[0046] The source of the original clip can be at least one of local video, network video, live video, and web page screen recording, and clips after any form of video editing can be used for transition processing;

[0047] S2: Select a transition position at the junction of two adjacent original segments, where the transition position is a stable frame sequence at the end of the previous original segment or the beginning of the next original segment;

[0048]The picture stability of the frame sequence indicates that the content of the picture in the frame sequence has not changed significantly. Therefore, a frame sequence with a stable picture is selected as the transition position at the connection of adjacent origina...

Embodiment 2

[0053] Such as figure 2 As shown, embodiment 2 discloses a kind of video transition special effect method on the basis of embodiment 1, and this embodiment 2 further defines the concrete method of step S2 as follows:

[0054] S2.1: Set the maximum duration t of the transition position 0 , and look for t at the end of the previous original segment or at the beginning of the next original segment 0 The group of video frames in the time, the total number of video frames in the group of video frames is n;

[0055] S2.2: Find at least one element in the video frame as a reference object, and randomly intercept a frame sequence of m consecutive video frames in the video frame group, where m is a natural number less than n and greater than 1; the comparison element is in the frame sequence group When the movement range is smaller than the preset threshold, the frame sequence is considered to be stable, and the frame sequence is set as the transition position.

[0056] The specifi...

Embodiment 3

[0065] Embodiment 3 discloses a kind of video transition special effect method on the basis of embodiment 1, and this embodiment 3 further limits the specific method of step S3 as follows:

[0066] S3.1: Set the transition effect mode for the transition position;

[0067] Transition effects include general transition effects such as dissolve, flash black, blur and dissolve, etc. You can also manually introduce or design other types of special effects;

[0068] S3.2: When the transition position is at the end of the previous original video, use the end frame of the transition position as the end frame of the previous original segment, and connect it with the start frame of the next original segment to obtain a spliced ​​segment; When the transition position is at the start of the next original segment, the start frame of the transition position is used as the start frame of the next original segment, and is connected with the end frame of the previous original segment to obtain...

Abstract

The present invention provides a video transition special effect method and a corresponding engine. Firstly, at least two original video clips are acquired and sorted, and a frame sequence with a stable picture is selected at the connection of adjacent original videos as the transition position to set the transition position. Field mode, and connect the adjacent original video through the transition position, so the original clips can be spliced ​​into a complete video without additional images, video clips and other patch content; and due to the content of the stable frame sequence There is no obvious change, and the transition setting here will not affect the key content in the original clip, so that the adjacent original video can transition more naturally and smoothly.
