It is all quite confusing....
I just want to be sure that I'm using best available settings for my hardware.
Thanks

(shutter encoder is based on ffmpeg)
NVIDIA says about "...ultra-high quality (UHQ) mode to AV1..." but TBH I don't know what it means.....
Video Codec SDK | NVIDIA Developer
Quote:NVIDIA GPUs contain an on-chip hardware-accelerated video encoder (NVENC), which provides video encoding for H.264, HEVC (H.265) and AV1 codecs.
The software enhancements in SDK v13.0 enable extending ultra-high quality (UHQ) mode to AV1 encoding.. This makes AV1 encoding on Blackwell NVENC comparable to software AV1 encoding with ~3X throughput. The UHQ HEVC mode was introduced in the SDK v12.2 in the Ada generation.
