RedCine Project Color Space

[RedWolfe]

I did a Log & Transfer to ProRes 2k for editing in FCP. now that I have picture lock I need to output 1920x1080 uncompressed 422 QuickTime files for final color at a post house. I understand all of the project/output settings in RedCine except for the project format color space. should I use Camera RGB or REC 709?

can anyone help here? I just need to know what color space to choose so that my uncompressed 10 bit 422 quicktime 1080p files have as much latitude as possible. this is for 4k to 1080p export from RedCine.

I suspect you want to be in REC 709 color space...

I would consult with your post house to find out exactly what they want, because it can differ depending on many things (colorist, grading system, final output, etc.). When working with a post house, good communication about work-flow and specifications is key to saving time and money.

I believe Rec. 709 - http://en.wikipedia.org/wiki/Rec._709

Here is an article about the differences between the two color spaces

If you want your files to have as much latitude as possible then Camera RGB is probably far better than REC 709. I don't know how the new REDspace compares with Camera RGB latitude wise, but it is more "accurate" and "natural" without any color correction applied. Since your footage is going to a post-house for grading, it may not matter as much.

You may want to consider using the REDlog gamma curve, as, according to Gramme, it is optimized to fit as much of the RAW image data as possible into 10 bits.

This is all assuming that the post house is equipped/expecting to do a serious color grade of your footage, and not anticipating that you'll be delivering something which looks like it was shot on Varicam to them.
