Not really, one day it just started working. For the Rockstar Editor to work properly in a FiveM server, you need a highly optimized server—no custom clothing or too many poorly made MLOs.
I suggest (high success rate):
- Clip the footage on the server,
- Press F8 and type
quit
, - Reopen FiveM and go to the Replay Editor,
- Create a project and start editing,
- Save the project, then press F8 and type
quit
, - Open FiveM again, go to the Replay Editor, and select the project you worked on (DON’T EDIT IT—JUST SELECT IT!),
- Start exporting it and hope it doesn’t crash. (This works for me.)
