The invention provides a video special effect processing method and device, electronic equipment and a computer readable storage medium. The method comprises the following steps: acquiring a video special effect file, and extracting time length scaling logic from the video special effect file; obtaining a target playing duration required to be realized by the video special effect file, the targetplaying duration being different from an original playing duration of the video special effect file; determining a special effect frame corresponding to a target time axis in the video special effectfile according to the duration scaling logic, wherein the length of the target time axis is consistent with the target playing duration; and performing rendering according to the special effect framecorresponding to the target time axis to form a video special effect playing process conforming to the target playing duration. According to the invention, the duration of the video special effect canbe automatically expanded and contracted as required.
Description
technical field [0001] The invention relates to digital multimedia technology, in particular to a video special effect processing method, device, electronic equipment and computer-readable storage medium. Background technique [0002] The development of the Internet, especially the mobile Internet, has enabled unprecedented use of video as a medium of information dissemination. In order to enhance the expressiveness of the information carried by the video and increase attention, related technologies usually add video special effects to the video. [0003] For example, in related technologies, special effects animations can be designed based on professional video editing and design software such as AE (Adobe AfterEffect), and Airbnb's open source hot animation library solution and Portable Animated Graphics (PAG, Portable Animated Graphics) solution can be used in AE. [0004] However, the duration of video special effects designed by video editing and design software is fix...
