Why nvenc did not support yuv422?

Hello @Lemon33 and welcome to the NVIDIA developer forums!

Sadly there is always a limit on how many circuits we can put onto our chips, which also limits the number of features we can support. I can understand if this might not be the answer you are hoping for, but which features to prioritize is based on internal decisions of our HW and SW teams.

Thanks,
Markus
