Media Composer 7.0Color Management (LUTs)
Igor Riđanović
Some new features in Media Composer 7.0
LUT and CDL support
FrameFlex AMA media management Background transcoding
Technology
MXF, MOV are wrappers carrying encoded essence and metadata
DNxHD, Prores are codecs
RAW are camera manufacturer proprietary files
Technology
AMA (Avid Media Access)
LUT (Lookup Table)
CDL (Color Decision List)
Rec. 709 color space
Terminology
Color model—an abstract primary color mixing principle
Color space—specific values for the primaries Color gamut—unambiguous color set defined by the primaries Gamma—nonlinear encoding
PAR
Color gamut
linear light intensity
Gamma
