[Feature]Add HLG Gamma for HDR metadata #163
Description
Add HLG Gamma for HDR metadata
NotEnoughAV1Encodes is a very good software to encode some videos that take a large aomunt of space.
Could the HLG Gamma be added to HDR metadata?
Because I want to use NotEnoughAV1Encodes to compress the video materials form my camera.
And could some professional gamma(like sony slog,BMD Film log) or gamut(like ACES,BMD Film Gen5) be added in the encoding workflows?
