Is it possible to create animation that would be similar to "page turn / curl" effect in FFmpeg between two videos? The basic idea: the first video is playing and after some time the second video is replacing the first video with this effect. On images below, blue color means the first video, black color means the second video and yellow color means the transition color between two videos.
You'll need (to compile) a ffmpeg build with a custom filter: https://github.com/transitive-bullshit/ffmpeg-gl-transition, or use node.js script here: https://github.com/transitive-bullshit/ffmpeg-concat
The transition is at https://gl-transitions.com/editor/InvertedPageCurl
