recently got a 4070 and testing out some NVENC AV1 rendering. I noticed that with the SVT there is a CFR rating that can be set., which i believe auto adjusts bitrate to keep the quality consistent while saving space? I have mine set for 40 for my needs
On the nvenc av1 encoder, i do not see the CRF, but i see the constant quantizer, so i set it to 40 as they show up as qp=40 in both of the encoders.
However, after rendering with the 2 different encoders, the SVT file size is 373MB, while the nvence is 1,64 GB in file size. Can someone explain the difference in the 2 encoders as both show the settings as qp for the settings.
