Hi, I’m having an issue with OBS recordings becoming corrupted after long sessions.
I recorded a video that was about 1 hour 47 minutes long at 1080p60. The recording starts normally, but later in the video the image freezes while the audio continues playing normally. After that point, the video is basically just the same frame repeated until the end.
Details:
I have now switched to MKV + auto-remux to MP4 to prevent corruption in future recordings

Details:
- Resolution: 1920x1080
- FPS: 60
- Recording length: ~1h47m
- Encoder: (NVENC / x264 – replace with yours if known)
- Bitrate / Rate Control: (if you know it)
- Recording format when the issue happened: MP4
- Repairing the file using FFmpeg (<span>-err_detect ignore_err -c copy</span>)
- Re-encoding the video with FFmpeg to rebuild timestamps
- Playing the video in VLC and other players

My questions:
- What could cause the video frames to stop encoding while audio continues?
- Is this typically caused by encoder overload or dropped frames?
- Are there recommended OBS recording settings for long recordings to avoid this?
