Haha I have no idea what you just said but I'm sure AI will give me a crash course, thanks for pointing me in the right direction! Will I be able to upload 2-3GB videos?
Sorry. I tend to make short videos. Peertube is better for larger videos. It's easy to host on Yunohost because you don't need to know DNS.

I think so, assuming you have the hard drive space.
Jellyfin will also work, but it requires a login. It's geared for motion pictures.
