Problems solved by technology

If the quality of the source video sequence is not high (the frame rate is low or the rhythm is not smooth), the superimposed special effects will not be smooth
[0003] In the prior art, special effects are usually added in the following two ways. One is to directly superimpose according to the frame number. In this way, if the frame rate of the special effect series is greater than the frame rate of the source video, the superimposed special effects will play slower. The effect is not good; the other is to remove some video frames of the special effect sequence, so that the frame rate is the same as that of the source video. This method makes the superimposed special effects appear stuck when playing.

Abstract

The embodiment of the invention discloses a video special effect adding method, device, equipment and storage medium. The method includes: obtaining a source video sequence and at least one special effect video sequence; the number of special effect video sequences is two or more, and the frame rate of each special effect video sequence is the same, then interpolating frames and combining with the source video sequence Superimposition of special effect video sequences; the number of special effect video sequences is two or more, and the frame rate of each special effect video sequence is different, then according to the preset rules, determine the target frame rate from the frame rate of the special effect video sequence, and The source video sequence is interpolated according to the target frame rate and superimposed on the special effect video sequence. The video special effect adding method provided by the embodiment of the present invention determines the frame insertion and superimposition method according to the number and frame rate of the special effect video sequence, and improves the playback efficiency of the special effect video sequence after being added to the source video by inserting frames to the source video sequence fluency.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of video processing, and in particular, to a method, device, device and storage medium for adding video special effects. Background technique [0002] In the process of video production, there is often the operation of superimposing dynamic special effects. The video sequence of the special effects part usually has a stable frame rate, but the quality of the source video may vary. If the quality of the source video sequence is not high (the frame rate is low or the rhythm is not smooth), the superimposed special effects will not be smooth. [0003] In the prior art, special effects are usually added in the following two ways. One is to directly superimpose according to the frame number. In this way, if the frame rate of the special effect series is greater than the frame rate of the source video, the superimposed special effects will play slower. The effect is not good; the other is to...
