as for the resourse, on the top of op, here are some:
(this one likely in the future, since the guy promised in his youtube channel to post those)
This one is official I think, so I wouldn't expect too much slip would be shown in their video
Pinkart3 is very decent, but they will cut out the best part.
snow cine is really really good compare to the rest of the source (once you check out his video you know what I mean), and his subscription is cheap af, so pls go join and support that guy.
I have no idea about nadurmok and video fantasy (memberme.net), I really want to join the later one but is too fking expensive, can someone please let me know the quality of their video? Do they show slip?
