Hello everyone,
I recorded very important lectures manytimes unfortunately some of these videos playing with only sound and the video streaming freezes on one image and not continues as a video i.e. I can only hear the sound without seeing anything.
These lectures are very important and thus I am asking whether I'm able to recover them? Furthermore, what is wrong with the recording as I take the standard settings. What are the best setting to make OBS reliable. two out of 7 videos are corrupted and not recorded properly.
Advice please.
Log file of the corrupted video is attached

You're using QSV for encoding, but your GPU is being entirely overwhelmed and cannot keep up.
If you're using ffmpeg for output, recommend switching back to Simple mode with QSV hardware.
If you're already using Simple-QSV, you may need to switch to Software (low-CPU) encoding.

I see!
FerretBomb many thaks for your reply. If I use the suggested settings will this help to record problemless videos?
Is there any way to recover the corrupted videos?

If you go to Tools, Auto-Configuration Wizard, it SHOULD give you safe recording settings for your hardware. The ones I recommended will be most likely to work on weaker hardware, but you should absolutely do test recordings to make sure.

No, there is no way to recover the corrupted videos, because the video was never actually recorded due to the encoder overwhelm. The data simply isn't there.
