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. WebMar 2, 2024 · For recording, my personal favorite is CRF rate control on X264 (or if you can hack obs to have it, X265). CRF provides the best compression for the best quality.
