And I don't just mean GIFs but full on videos w/ audio. Where is it, mods?

That’s both a good and bad idea. Aside from the note that it’s probably only going to be able to be accessed by imgflip Pro users, it’s likely going to end up like YouTube Shorts or even TikTok. Besides, I don’t think we want this site becoming either of the two, but it would be nice to be able to upload a 5 minute video or something.
