Re: Gamma shift in Log RGB 444 Export
by Martin B. Wehding on Mar 21, 2008 at 12:07:22 pm

Hi jim
I Have the same problem, using AJA 10 bit RGB full range.
I wrote to AJA's support and it is finaly confirmed by aja that there is a gamma shift in color.

There are gamma issues with Color and we are working with Apple on
getting
them resolved.


I have now moved my project to DPX files...

BTW. Another problem was that color somehow "assumed" that the material was smtpe (probably because it was QT) so the result was that 0 was mapped below o IRE on the scope and 1023 over 100 IRE. After i moved to DPX it's all shown correctly 0-100. (I could'nt overide the header in color, guess that function only works on DPX files)

my 2 cent
martin
