Clarification on maximum brightness in nits #8

Closed zmarty closed 6 years ago

zmarty commented 7 years ago

We would like to upload some HDR video that goes above 1000 nits. The official documentation recommends outputting content as ST.2084 1000 nits. Is this just a recommendation or an actual limitation?

Will uploading content at 4,000 or 10,000 nits work fine?

That is just a recommendation given current status of TV. HDR bits are essentially pass through. The SDR downconverted version may be poor if the color grade is too high key.
