What do need to learn to get into virtual production?

Hello, ive been browsing unreal engines channel for a while now and their content on virtual production interests me and is something I would like to learn seeing their cinematics and motion capture shorts looks rewarding its finished. After diving and playing around with the engine for a bit I still have no clue where to “actually” start to learn virtual production. I wanna make motions capture shorts like they do in tech demos. Does anyone know where i can find the information for a beginner?

What do i have to learn?
Rule 1/3?
