Create and sell movie, intro, trailer? legal?

Hey Folks, can i create a Movie and publish it (e.g. Youtube with advertising) or just sell it to a client (typical commercial use)?

  1. Do I need to pay this 5% afer 1,000,000 USD?
  2. The revenues from all videos together?
  3. How to calculate revenue?

I’m realy confused.

Workflow:

  • create a scene with the unreal engine and quixel (unreal unlimited)
  • rendering out cinematic movie
  • export to after effects
  • sell this movie to a customer
