I have used the Roblox Player’s built-in video recorder for recording Roblox experiences, and I have to say, it doesn’t record in the greatest quality, just see the below examples:
It’s grainy, stuttery and laggy. Anything I can do about it?
Roblox’s recorder is known to be bad. Don’t use it. Yes, OBS is the best you got
Roblox’s recorder sucks, Just use OBS (I use Xbox recorder but it’s bad because it only works in one app)
Okay, assuming this behavior is not intended, I have gone ahead and filed a bug report: Built-In Video Recorder Producing Low Quality Results - Bug Reports / Engine Bugs - Developer Forum | Roblox.
