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

[adrian hauser]

Hi,

I am having some confusion regarding Dual link Monitoring 
setups for the grading of films in a DI domain.

I have two workflow paths that I am looking to verify.

#1 Log Scans in - grade in Linear HD color space and output
Linear HD DPX sequence for input into the ArriLaser HDCMS software
for Filmout. No Monitoring Luts used. The HDCMS software
assumes a REC 709 HD source.

#2 Log Scans in - Grade with calibrated Monitoring 3DLUT and Output Log
DPX sequence for filmout.

In Both cases the DI grading system will be producing the 
master DPX image sequences that will be sent to the Film Record 
Facility. In both cases I believe the rendered files are always 
encoded "Full Range" RGB.

I am working with a Conform/grading system 'Scratch' where monitoring
variables are set in NVidias SDI output GUI, not within the program
itself. 

So given the above variables when does one select 444YUV 
or 444RGB for dual link monitoring. Aslo when working in
YUV I have the options to work in full range 0 - 1023 or
'video range' 64 - 940.

Thanking you in advance for your input.
