[Tig] When to use 444RGB or 444YUV for Dual link monitoring in a DI

[adrian hauser]

Thanks Tim,
My confusion is actually encountered only in the Lin "HD Video space" output translation to film at the moment.
Log out is fine....as it can be.WYSIPMWYG . What you see is pretty much what you get:> ....except unexpectedly better.

This from Arri:
>When you watch and grade a RGB image on a ITU709 monitor the resulting file will be an ITU709 RGB file. By >definition. 
>And that is what the ARRILASER CMS is expecting. 
I find this confusing because Im monitoring RGB on a HD709 Monitor but my rendered files 
are only RGB. Do you know of a RGB to 709 translation 3DLut? Unfortunatelty the program cannot use a 3x3 matrix 
so I think I may need such a LUT as an ASCII 3DLUT to imbed in the render.
Regards,


Adrian Hauser

  ...with RGB monitoring is the only thing I'd consider appropriate for a film project. As important: are you going to work in log, or in float linear? If the latter, I'd strongly advise actually QA'ing the entire log output as log, no preview LUT.
