That logs shows numerous recordings, and encoder overload in many (all?) of them
no, there is no recovery of what wasn't recorded
especially the hour long
15:13:34.513: Video stopped, number of skipped frames due to encoding lag: 202401/202797 (99.8%)
ie - almost nothing actually recorded
Always test first. at this point, your settings, with what you are running, combined with your hardware, doesn't seem to be a match
- Make sure Operating System is optimized
- Adjust OBS settings, leaving some headroom, for recording (start with auto selected settings, adjust from there). At a minimum, I'd start by dropping to 30fps
