NTSC vs. PC monitor?

Not related to the DVX in particular, but...

Anyone know precisely what the difference color-wise is between a PC monitor (and/or a Mac monitor while we're at it) and NTSC?

Obviously the DVX and video cameras in general are calibrated to output to NTSC (in U.S.). What saturation/gamma/gain/whatever settings get the footage to precisely match original NTSC colors when played back on PC monitor (both CRT)?

In other words: I've been working on a project, and doing color correction off a NTSC reference monitor and I've gotten everything to look the way I want it on there. But then to author an .avi for net release that will have the same look as the stuff going out NTSC.... i should....?

I can kinda fudge around with the footage by eye and get it close, But it seems like there must be some quantifiable scientific numbers out there that I could just plug in and voila.
 
Re: NTSC vs. PC monitor?

Hey David, is that preset in Vegas 4 or Vegas 5? I don't remember seeing it, but I don't remember looking (I haven't looked under the hood of probably 90% of what Vegas can do!) But that would be a very interesting filter/color correction/whatever...
 
Re: NTSC vs. PC monitor?

I believe it's "Studio to Computer RGB" or something very similar. It's in 4. I assume it's in 5, though I haven't looked for it specifically.

Brilliant! I found it in the Video Event FX/Color Corrector. They do have a preset there, one for converting video so it looks on your monitor like it would look on your television. It is, as you said, called "Studio RGB to Computer RGB" and it's in Vegas 4. Awesome!
 
Re: NTSC vs. PC monitor?

And for those of us NOT using Vegas (I'm a Premiere fellow myself) does anyone know the math that's going on there so I can do it manually?

Although Barry seems rather excited about the filter in Vegas, so maybe I'll just send him a DVD of every project I ever do from now until the end of time and let him convert them for me. :)
 
Re: NTSC vs. PC monitor?

I don't have it in front of me, but I suppose I could look later and tell you what the color wheel/gain/black balance settings are, if it would help.
 
Re: NTSC vs. PC monitor?

To do what the Vegas preset does, increase saturation by 16.4%; increase gain by 16.4%, lower the black offset to -18.6.
 
Re: NTSC vs. PC monitor?

Anyone have an idea what Vegas' "black offset" control actually is? Sounds like a black pedestal control? But I don't know, there's no control by the same name in Premiere. It's probably just a different name for a similar thing.

Seems strange that every editing app doesn't have exactly the Vegas filter David pointed out. It's just such a common occurence-- exporting something both NTSC and for web. What is everyone else doing when they export for web? Just leaving it NTSC colors? Eyeballing it? Seems strange that every editing app on the planet doesn't just have a "compensate NTSC colors" button built in.

Thanks much for the help David. I'm almost there. :)
