Question about color space

I work mostly with hdv and dv , and for what I was reading the other day ( think it was an article by Glen Chang ), the preview window seems to need "studio rgb to computer rgb" preset in order to show an acurate picture for color correction.
My question is , is it posible to achieve the same ,changing the settings in the envidia control pannel.Like moving the gamma slider, so that the preview window shows a color closer to what it would be on an external monitor.Thanks.

The preview window and the vegas video scopes are "calibrated". Both should be set to match either computer RGB or studio RGB, in sync with each other. CC MUST be made with the vegas FX. Changing the color settings in your video card control panel will change only your display. It won't change the files being rendered. So, while your preview window will look right, rendered files will be wrong.

Thank you, I understand. I guess my idea was that if I can make my computer monitor
look like an external tv (connected through firewire) , then I could semi accurately work with the preview window only.

I think the first post was asking if there is a way to match the Vegas preview window to an NTSC color space (or other color space) in order to do visual adjustments without needing an external monitor.

Something similar to the "simulate device aspect ratio" except for color rendering.


edit: oops I guess I was to slow in posting.

Yes. I just discovered yesterday playing with the controls of my video card and having Vegas opened, that the video in the preview window changed as I moved the envidia controls. So I figured may be I could aproximate the "studio rgb to computer rgb" color without using an fx plugin ,(The fx slows my real time frames per second in the previe window).

Another way to work is this:
A- Leave the video card settings alone. This will make it easier to check other work. e.g. if you render a WMV out of Vegas, you can open that clip and see the colors as they should be (without distortions from changing your video card settings to something non-standard).

Plus, you may not get the values correct when changing the video card settings (depending on how you do it; it might be possible though I haven't bothered figuring it out).

B- As your preview device, use a Windows secondary display.

In the preferences for preview device, check color management. Check the studio RGB box.

C- Sometimes B will be inappropriate, depending on what codecs and mode your project is in.
