Using an 8 bit codec with HDR content may affect video quality
I am trying to export HDR for YouTube in Compressor from FCPX 10.4 and I keep getting this warning. "Using an 8 bit codec with HDR content may affect video quality". But it is was shot on Panasonic VLogL at 10bit and was setup in FCPX as wide gamut. Can anyone tell me why I am getting this warning and how to fix it?
