What is the difference in
Main
Main10
Main12
Main422-8
Main422-8
Main422-10
Main444-10

[jagabo]

Main		 8 bit per channel, 4:2:0 subsampled chroma
Main10		10 bit per channel, 4:2:0 subsampled chroma
Main12		12 bit per channel, 4:2:0 subsampled chroma
Main422-8	 8 bit per channel, 4:2:2 subsampled chroma
Main422-10	10 bit per channel, 4:2:2 subsampled chroma
Main444-10 	10 bit per channel, full 4:4:4 chroma

@jagabo does it same goes with baseline and high and other profiles?

https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding#Profiles + https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding#Tiers_and_levels should help

Wikipedia has too long and confusing information..
Do high and baseline profiles also has options like 4:2:0, 4:2:2, 4:4:4 and 8/10/12?

[Selur]

https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding#Profiles
-> HEVC has no baseline profiles,....

[Anonymous543]

So basically for other codecs documentation if there written
High444-10

Then they mean to say
Profile - pixformat - colordepth <<This is the syntax? Right?

[Selur]

yes, if you choose to write it that way the usual interpretation would be: <Profile><max supported color sampling>-<max supported bit depth>
