OBS Recordings "freezing" midway through the recording session with no apparent crashes.

[Erick Smith]

I started using two instances of OBS now. One instance, which acts as a server, has two scenes: One scene for capturing from Elgato for consoles and the second scene for capturing the desktop. Then I can select a source from the OBS Virtual Camera. Once I click Start Virtual Camera in the first instance, I use the second instance of OBS to broadcast. On the second instance, added a Video Capture Device and select OBS Virtual Camera from the first instance.

The perks: This way, I don't need to use any projections, which will slow down capturing and gaming. I don't need two monitors for capturing the desktop. I can set the first instance of OBS to a higher or lower FPS; the OBS Virtual Camera will use the FPS of the first instance. I can now observe logs to get detailed info on what is causing freezing or slowdowns. I also don't need two computers.

What I would like to try next is: Run the first instance over Fat32, ReFS, change the cluster sizes, try different hard drives, maybe physical drives work better, like a Western Digital Purple drive?

After some testing and the ability to "get between" things, I found that the Multipass Mode's default two pass Quarter Resolution is causing some hiccups because its analyzing a quarter of the resolution on the first pass, then optimizes on the second pass as it encodes. I set it to Single Pass. Stutter be gone.

Wow. I'd never think to do that. That's pretty clever. Though I'm only recording the console. And so far I believe it only seems to happen if i take OBS out of focus. Not sure; maybe something to do with what is currently using my graphics card? But that doesn't make too much sense. Anyway, if I just leave my pc alone while recording it doesn't seem to freeze. Actually now that I think about it it might be the cable connection. Maybe. :/

That's where my gears were turning too.....cable issues. Bandwidth....or something. Maybe try different encoders? Maybe observe the logs after a finished recording and observe file latencies?

[Edit]
It might be a Windows Multiplane issue, or happens when you hide it. That's when I thought about switching to the Windows Game Capture, or the selection that states, Windows 10 and up and enabling HDR, because that will make the bandwidth increase. I think you are on the right trail there.
