Dear all,
I have a color encoding problem with my standalone DVD recorder.
I recorded many films(200) with it using a RGB scart from my sat receiver.
But all my films are looking very green.
I used DVE essential played from a DVD player and the results are that looking to Red, green, blue, magenta, cyan and yellow patterns, I know now for sure that the problem doesn't come, only, from the A/D converter of the DVD recorder.
It means that RGBAdjust can't correct the problem itself : the correction is not a linear combination for R, G and B independantly from each other. In another words:
R(corrected)=a+b.R(initial), G(corrected)=d+e.G(initial), .... is not the solution..
The problem comes from the color encoder matrix in the DVD recorder:
(YUV) = M. (RGB) during the encoding process!
Of course, I can compute manually the coeff of the corrected matrix M (with the help of the DVE color patterns),
but how can I enter the computed matrix in an avisynth script after?
Thanks
Francois
