Abstract

The present invention provides a video special effect processing method and device, wherein the method comprises the following steps: acquiring beats per minute BPM corresponding to a background musicin a video to be processed; acquiring a selected special effect, and a video segment to be subjected to special effect processing in the video; determining a rendering period of the special effect according to the BPM; for each frame image in the video segment, determining the special effect segment to be rendered according to the time point of the frame image and the rendering cycle of the special effect; rendering the frame image according to the special effect segment to be rendered, and obtaining a special effect frame image; combining the special effect frame image corresponding to eachframe image to obtain a special effect video segment, thereby achieving the consistency between the special effect and the beats of the background music, ensuring the harmony between the special effect and the background music, and improving the special effect processing effect of the video.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a video special effect processing method and device. Background technique [0002] At present, in short video applications, such as Douyin short video, when special effects are processed on short videos, the frequency of special effects is fixed and cycles at a fixed frequency, such as shaking, soul out of body, etc. When the soundtrack is added to the short video, the fixed-frequency special effects are likely to be inconsistent with the beat of the soundtrack, resulting in disharmony between the special effects and the soundtrack, and affecting the special effects processing effect of the short video. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, the first object of the present invention is to propose a video special effect processing method for...
