I though it might be useful to start a thread dedicated to the way Vegas 9 (first build) reads the .r3d information and the way it outputs it to a monitor for proper color timing.

Nicholas posted this on his thread which shows a stark difference between what Red Cine and Vegas look like:

The difference in pics can be found here...

My hope is that those who understand better may figure out the proper settings or combination of settings to make Vegas display like Red Cine does. Or that maybe Sony will be taking a look at out concern and fix this in the upcoming updates.

Change the color settings in the project to "32-bit, full-range" (I think that is what its called) and the color should match much, much more closely. I haven't done a comparison, but reviewing old footage (that I spend a lot of time looking at), it looked to be pretty close.

I found some settings which seemed to work reasonably well, see this post:

I used color temp. and tint to get the greyscale patches right but the rest of the colorchecker is not a good match to proper colors.
EDIT: Wow, using 32-bit full mode, it certainly looks different- colors much less saturated, and probably more accurate. My first try with the saturated, super-yellow version was the 8-bit default mode.

UPDATE: getting closer with these settings:
Color temp: 6200 (note: color temp. of actual light was 5150 K)
Tint: +8.0
Saturation: 1.50
Contrast: 0.35
Gamma curve: Rec. 709
Color Space: Camera RGB
ISO: 320
Vegas Project: 32-bit, full range

Vegas 9 file attached in ZIP format. The original R3D is here (small enough to download easily):

I see. Thanks for sharing! I use 32-bit full to finish, but 8-bit does seem great to cut in my slower computer. I don't have a color critical monitor right now though, just a decent consumer LCD but maybe I'll plug your numbers in and see what they look like once I burn a DVD and play in my TV...?

However I think it isn't in the processing that Vegas is messed up but in the way it displays the colors... so maybe it is best to leave it alone until Sony fixes it? If we tried to compensate to make it look right on our displays we would be actually throwing it in the opposite direction when it didn't need it and something that looked to have a Magenta bias would end up looking Green in your renders, so on so forth... Right?

By all means, I'd advise that you test on your system, your footage and your final output format and display method and determine what works for you. What I posted is a starting point for what works for me.
