Abstract

The invention provides a method and a device for adding a special effect into a video. The method comprises the steps of acquiring a video file and an animation file used for adding at least one special effect to the video file ; decoding the video file to obtain frame data of a plurality of video frames of the video file, and decoding the animation file to obtain frame data of a plurality of animation frames of the animation file, wherein the video frames and the animation frames have a one-to-one correspondence relationship; simulating a graphics processor, and operating the simulated graphics processor; according to the frame data of each video frame and the frame data of the corresponding animation frame, performing animation rendering through the simulated graphics processor to obtaina plurality of target video frames; and performing video synthesis based on the plurality of target video frames to obtain a target video file added with the at least one special effect. According tothe method and the device, the problem that a low-end mobile phone is stuck in animation rendering can be solved, and batch production of special effect videos is realized.

Description

technical field [0001] The invention relates to video processing technology, in particular to a method and device for adding special effects to video. Background technique [0002] With the vigorous development of the short video industry, the demand for batch and large-scale production of special effects videos has become more and more intense. [0003] In related technologies, Airbnb's open-source Lottie solution can realize the workflow from animation design to terminal presentation, that is, designers design animations through graphics and video processing software, such as designing animations through AE (Adobe After Effects), and the designed animations are exported through export plug-ins. And load the rendering on the terminal through the software development kit (SDK, Software DevelopmentKit). However, due to the relatively weak performance of the mobile phones used by some users, if the animation rendering of the video, that is, the operation of adding special effe...
