Computer RGB from Studio RGB

When does one need to color correct a whole project from Studio RGB to Computer RGB?

I'm used to working in the pure video side, such as DV/HDV/XDCAM, where everything I do is Studio RGB in Vegas. And the only corrections I need are going the other way, such as taking scanned pictures and correcting them from Computer RGB to Studio RGB to mix with this footage.

So when I render back to these normal video formats, I'm fine. But what about when I render from Vegas to say WMV or QT or H.264, or take the video outside Vegas to render a Flash FLV. Do the renders, at least direct from Vegas, account for any Studio to Computer RGB changes, or do I need to manually do this to the project first?

Thanks.

No.

You can nest your project and slap a studio RGB->computer RGB color corrector preset on that.

Now it's possible to stick that FX on your current project and avoid nesting, but that's dangerous if you start using render to new track.

2- I assume that you are using an 8-bit project.

Yes, 8-bit. OK, so I should color correct them to Computer RGB.

I should do this when going to ANY computer or internet format like WMV, QT, H.264 or FLV, correct?

Thanks.

For the most part yes. It comes down to what the codec does. The MPEG-4 codec that comes with Vegas for example has an oddball behaviour (it's studio RGB in 8-bit projects).

I'd just look it up in this table:

Ignore the 32-bit column since you aren't dealing with that.
