====== Fun music visualizer with FFMPEG ======

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!
