Hey @avrahams_nose! Post-production editing would be, as an example–taking the Sequencer export into Premiere, After Effects, or Davinci Resolve, etc. to edit, change, improve or correct the video in any way. The only permitted used of post-production editing is if someone is using Movie Render Queue, and wishes to add audio. There are ways to do this with MRQ within UE. However, it requires further documentation improvements, which is why this is allowed. We reserve the right to ask you to provide a screen recording of running the render from Movie Render Queue.
I hope this also answers your question @jsabbott
