Uh so maybe you want to make cringe videos out of an mp3.
Well I got you.
Here is my current go-to for creating a 4k60 output that uses every ffmpeg visualizer I could find. Even includes a bouncing DVD logo aesthetic with the cover art (second input file).
Output is mpeg2video since I used to do this on a 4th gen Intel Haswell system that would cry encoding 4k at h264. You'll want 1:1 scaling at high bitrate for the vectorscope to look cool.
Have fun!
