Garry's Mod Ragdoll/NPC Posing for films

Is there tutorial or anything about how to make your ragdoll/npc mouth move when it speaks, How to make the fingers move or make some bodypart move. Like key framing. How to make good looking First Person fights etc. These questions might be bit weird

Thanks

Most of them are doing stop motion as far as I know.

along with other techniques though, there’s probably a few tutorials, you could also use SFM

There’s a tutorial on a part of that video.
