WebCRF != CQP. The former may have variable QP but tries to maintain quality. CQP is a cruder form of rate-control. For nvenc, use -rc vbr_hq -qmin 0 and add -cq X where X sets a quality level; range is 0-51. Smaller is better. Share. Improve this answer.

WebJan 14, 2024 · CQP and CRF are quality targets, so this sort of thing could easily result in bitrate spikes of 100mb/s+ or so (and when youtube re-encodes most of this is getting thrown away). VBR keeps this sane, and is probably better for longer recordings. Also given that esports broadcasts aren't post-edited, this also makes VBR a suitable choice for them.
