  1. Media Composer 7.0 Color Management (LUTs) Igor Riđanović

  2. Some new features in Media Composer 7.0 • LUT and CDL support • FrameFlex • AMA media management • Background transcoding

  3. Technology • MXF, MOV are wrappers carrying encoded essence and metadata • DNxHD, Prores are codecs • RAW are camera manufacturer proprietary files

  4. Technology • AMA (Avid Media Access) • LUT (Lookup Table) • CDL (Color Decision List) • Rec. 709 color space

  5. 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

  6. Color gamut PAR

  7. Gamma perceived brightness recorded intensity Wolphram|Alpha linear light intensity

  8. Device dependent color—numerical representation Values are intrinsically tied to the device R 255 G 255 B 000 R 255 G 255 B 000 sRGB color space (computer monitor) mystery color space (some handheld device)

  9. Device dependent color R 205 G 012 B 005 R 205 G 012 B 005 device 1 source device R 205 G 012 B 005 device 2

  10. Device dependent color R 205 G 012 B 005 source device R ? G ? B ? device 2

  11. Device dependent color CMS R 205 G 012 B 005 source device R 212 G 008 B 010 device 2

  12. Project setup • Y'CbCr—4:2:2 chroma subsampling • R'G'B' – 4:4:4 sampling • Both use 2.2 gamma

  13. AMA plugins • Plugins are provided by third party manufacturers • Open console window: CTRL+6 or Command+6 • Execute AMA_ListPlugins

  14. Camera files link/import

  15. Built-in scope and histogram operation

  16. CDL (color decision list) TITLE: ONE EVENT CDL 001 Reel01 V C 10:05:29:14 10:05:43:08 01:00:00:00 01:00:13:18 *ASC_SOP (1.000000 1.000000 1.000000)(0.000000 0.000000 0.000000)(1.000000 1.000000 1.000000) *ASC_SAT 1.000000 Slope Offset Power p out = (i x s+o)

  17. Legacy files import • Correct level settings • New color options for AMA linked files • FrameFlex

  18. Legacy files import
