contrast shift when exporting at 10 bit
Posted: Thu Jul 26, 2018 11:17 pmHi,
I have Davinci Resolve 14, and an Imac 5k retina computer. (I also have a 1080p Eizo monitor, but I think the types of screens are irrelevant to this problem. Though the mac hardware might be relevant.) In Resolve, when I deliver as an xml by exporting the video files at 8 bit uncompressed RGB (full color spectrum), all the colors in Adobe Premiere look exactly as they do in Resolve. (I am unable to tell you what they look like if I export directly to a file, because the codec used by Resolve for an 8 bit uncompressed RGB export is unreadable by quicktime.) In Resolve, when I deliver as an xml by exporting the video files at 10 bit uncompressed RGB (full color spectrum), the video file has very noticeable increased contrast (lights much brighter, darks a little darker) in Premiere. When I export the video from Resolve directly to a file using the Prores 4444 or 4444 xq codecs (full color spectrum), the same thing happens: the video file has the exact time amount of increased contrast (lights much brighter, darks a little darker). As the original files are RED R3D files, I'm assuming the Prores 4444 and 4444xq exported files are either 10 or 12 bit files.
My question: why is it that when delivering/exporting from resolve at 10 bit (either as a quicktime file or as an xml to be opened in Premiere) do I get this increased contrast? But when delivering/exporting at 8 bit, the colors and tones match perfectly.
Regards,
Wylie
