How do they work with video material in Hollywood?

Question

Video processing

I'm interested in what kind of hardware video processing and computer graphics rendering takes place on, what software is used to create blockbusters and, in general, the whole process of post-processing the footage. Maybe links where you can read or watch.
Maybe I formulate queries in Yandex incorrectly, but I didn’t find anything sensible, so I ask you not to send me there;)

Answer 1

Mac's, some final cut pro or something like that.. this is editing.. and the effects themselves, I won't be surprised if they are still made on sgi computers with their software.

Answer 2

Pixar's RenderMan . List of films made with it
