I FOUND IT!
I ACTUALLY FOUND IT
For no reason at all I went to furbooru, did a search for FoE art, found the comic, whose comment had a link to the YT vid!
Transferring and embedding subtitles using YT-dl & ffmpeg is ... complicated, but it seems to have worked. Or just review the comic that's translated a bit better while you watch the animation.
