!idiotsincars@lemmy.world was always a slower sub on Reddit, but I've yet to find a good way to directly link to mp4s without shelling out $50 a month or relying on community supported sites. Even then I just found out Inline videos aren't supported on all instances (lemmy.world | it works on lemm.ee), and even still, not every app is doing in-app playback.
Posts do get decent traction, but I don't think we're going anywhere until this video thing gets sorted out.
I have seen someone use https://toobnix.org for videos, which is in the Fediverse.
Part of me wants to upload videos to Fediverse places and link there, part of me wants to stick them on YouTube and link to that because I feel bad using Fediverse resources, all the space my video takes up, but have no guilt using up YouTube's resources.
