Experimenting with "shorts". Basically I am just making a 1:1 less than standard-def version if the bit is too short to merit a full video. I think this works alright.
PeerTube still gets the original 4:3 version, but I have to take some minimal effort to reduce the black-boxes for people scrolling through YouTube shorts.

In this case there are still black-boxes on the 1:1 version except when the logo zooms out. So hopefully it was worth it in this case. I'll try to remove any builtin black-boxes from the source video in the future if I can help it (and it isn't an intentional bit).
