Yes, but I think the latest codec that canon uses in their newest cameras for 10 bit 8k raw are now supported. I'm not sure if it's hvac265 or something else
FWIW, the name is HEVC or H.265. AVC is H.264.
This yes, but it still gave me a chuckle to read HVAC, because I often see HEVC and think HVAC.
I do need a significant amount of cooling when doing GPU-heavy things.
