I've been trying to make custom load screens for the game but I only get a black screen.

I use the RAD Video Tools program and since I don't have a license for it, I change the file type to .bk2 when saving the converted video. I even mixed it down removed the sound from it and changed the title to "BG_LoginVideo_01" Is that the only thing I need to do? Or could it be the length of the videos I've been trying to use?

You have to use the Bink tool from the unreal engine as that version is 2.8 fully licenced and files made from the free license which is version 1.0 isn't compatible with the game https://docs.unrealengine.com/4.27/en-US/WorkingWithMedia/IntegratingMedia/BinkVideo/
Thanks!
