Question / Help Set minimum file size for replay buffer clips?

[SmakSupreme]

I need to use advanced output mode, and I only see a setting for the file size in simple output mode. I set it to 5 minute clips, but it only saves about 2 minutes. How do I get it to save more?

That duration implies you're using CBR for recording instead of CRF or CQP (depending on the encoder)

Thanks for the answer. Can you quickly explain to me what the difference is, and what CQP settings I should use if I want to record in 4k caliber quality?

What happens if you set x264 encoder (CRF), then set limit to 1024MB, apply changes and revert encoder back to NVIDIA?

CBR is constant bitrate
CRF and CQP are quality based bitrate targets.

Using CBR for recording, especially with nvenc, can cause the problem you describe.

Ideal quality comes in the 14-23 range for CRF/CQP values.
