So vimeo now supports “Dolby Vision” Or apples special sauce variant that works with relative luminance levels and is HLG based but has dynamic metadata - Now I am not opposed to HLG , I actually preffer relative luminace mapping for many usecases (like mobile viewing) Absolute luminance mapping like what PQ is doing is great in theiry but only really works in proper home cinemas , you will not watch a Dolby PQ movie in the middle of the day in your living room unless your TV adjusts the lumiance and then whats the point.
So but back to the dolby thing - how do I make a HLG/Dolby master file with proper metadata is this just with fcpX? Is it just a auto button, if so why cant the player just analyze maxfall and maxCLL and then apply “dolby curves” during playback - no idea anyone has more insights compared to the tech docs of vimeo?
We further support the upload of encoded Dolby Vision files. Dolby Vision for Vimeo uses an HLG base layer with Rec. 2020 primaries and Dolby Vision dynamic metadata. Using Dolby Vision for Vimeo, the metadata is automatically included inside the file. There’s no additional metadata required for upload. The HLG transfer function enables backward compatibility with a range of non-Dolby Vision devices that support HLG playback.
