Large recordings failing. Could not recover this time. Need help with root issue too

[SaveMeJebu5]

Like the title says. I performed multiple test recordings because I lost a large file before - and realized that short clips seem to work fine, but not the larger (more important) ones. This has been quite a pain in the buttocks. I dug around and found the recordings were not being saved out properly because it failed during the "Stopping recording" part. I only realized this because I was forced to close OBS after it spent longer being stuck on "Stopping recording" than it did actually recording. Then I would find the app still running.

I would get freaked out, then find the recording (I record in .MKV). Until yesterday!!! - and now it seems I lost an entire hour of video I definitely cannot record again, and desperately needed (five way video interview). I was watching, ensuring the video was going, and after trying to save it out I just quit the thing. Then I checked the OBS videos folder, and saw no file this time! where else might it be and what do these logs reveal about the issue? because this is NOT working

Additional info: This occurred again the other night. When I checked the logs I noticed this. The log above is having the same issue:

Input Queue is full, encoder is overloaded! No output Packet, encoder is overloaded!

Will attach the logs as well

This happens if the encoder is overloaded. Some overload situations result in skipped frames only, but more serious overload situation result in the encoder completely ceasing operation. In this state, it essentially stopped writing to the video file - the video is lost from this moment till the end.
To fix this, use the usual measures to reduce the load on the encoder: reduce GPU load from the app you're recording, reduce resolution, reduce fps.

That actually makes a lot of sense given my system config. Okay, I will try fiddling with the encoder settings to see if the result improves - then report back. Thanks!
