profile bitdepth color sampling confusion

Open Selur opened this issue 5 years ago • 1 comments

According to https://en.wikipedia.org/wiki/AV1#Profiles High profile (--profile 1) supports 4:2:0, but when I use 8bit with profile 1 I get:

Profile 1 requires 4:4:4 color format

High profile (--profile 1) supports 4:2:0, but when I use 8bit with profile 1 I get:

Profile 1 requires 4:4:4 color format

Professional profile (--profile 2) supports 4:2:0, but when I use 8bit with profile 2 I get:

Profile 2 bit-depth < 10 requires 4:2:2 color format

-> would be nice if someone could clear up which profile bit depth combinations support which color samplings (in AV1 and aomenc in case they differ)
