I have the same question, but regarding video. I see upload video as an option, but it does not seem to be working.

I spent most of my reddit time on video art subreddits.
Like r/stablediffusion r/curcitbending r/mediasynthesis and most of all r/videosynthesis

m/videosyntesis has been made, but is only me and the mod for now. Hopefully we can get people to migrate in time.
