Question / Help New Versions "Stopping Recording" Error

E

FIRST OF ALL, I record at 240 FPS. This is because in premiere pro I can use frame blending to create a motion blur effect on my gameplay.
I would like to keep recording at this frame rate, so changing it isn't a solution.

THE ISSUE:

So I noticed newer versions of OBS (approximately ones above 20.0.0) produce a "Stopping Recording" error when I record at 240 FPS with them.
I've been using version 20.0.0 for a while now as a fix but I felt like posting it here may help bring a proper fix to light.

The OBS log produced after the issue happens is posted here too, in case that helps.

It does not give me the "encoding overload" message when this happens either, and recordings from v20.0.0 don't come out choppy at all.

LASTLY, yes I know I'm using a beta build. I was just trying it in case it fixed the issue, but it didn't. If anyone could help me find the source of the problem I would greatly appreciate it!

You're using an experimental module of an experimental OBS version. I propose you work out issues directly with the developers. This will help development. Here in the forum no support can be given for this, because nobody knows how stable this experimental module is and what issues are still open with it.

would you like me to recreate the issue on a stable build and post that log instead? the issue is the same.
 
If you record to MKV you won't lose your recorded video to corruption due to not stopping recording.
While it doesn't solve your issue, you won't lose everything like you will by recording to MP4.

With MKV it doesn't matter, OBS can straight up crash and the file will still work. If you need MP4 then after recording goto File>Re-mux Recordings and turn it into a MP4 file.

There is a reason why there is a massive warning message when you have MP4 selected

How long does it usually take to convert mkv to mp4 (I know this would change depending on PC specs, but in the past I've seen mkv to mp4 coversions take a REALLY long time)?

File sizes can be quite big, but not as insanely large as you'd think.

UPDATE:
Using .mkv still doesn't fix the issue. It doesn't even create a file in place when I start recording, and the bug still occurs. I'm gonna post a log of the issue while using the latest released version of OBS instead of the beta here, maybe it will help.

And out of nowhere... it worked? Time to experiment.

Set B-Frames to 0... Issue happens again.

Set B-Frames to 2... ISSUE HAPPENS AGAIN.

I don't quite understand this, but thank you so much?

4 B-Frames is the answer I suppose!

Haha I guess I did find a solution- but now let me try it in game and with mp4 etc.

mp4: worked

VBR: didn't work

Guess I'll be using these settings haha, thank you again!

EDIT: I guess sometimes it still has the issue? Strange. Works usually though.

Don't record with VBR, CQP is better.

My setting of 16 though might be overkill, you can test from 23 and work your way down until you get the level of quality you need. If you don't care about space, then 16 or 15 (Lower is "better"/less compression/higher bitrate)

I'm aware, I usually use 18. I'll do some more testing.
 
Also don't record directly to .mp4 unless you really like doing a recording for hours and then getting nothing, because there is always a chance that will happen.

Yeah keep hearing stuff like that. I wonder why Premiere Pro doesn't just support mkv natively, probably some reason for it.
 
Remuxing is fast, easy, reliable, and built-in to OBS. It is not worth recording in mp4 and risking losing hours of footage to avoid seconds of remuxing.
