Multiple Vignettes - One Secondary

Hi,
I am working on a music video grade, where i will need to use multiple vignettes on one secondary as i will be selecting areas of the frame and grading inside and fully desaturating everything else to black and white. Once i have done this on one secondary, as i will have pulled all the color out of the rest of the frame, i can't use another secondary to pull up other areas, so i really need to select multiple shapes (vignettes) on one secondary.
Does anyone know if this is possible, or if there might be a workaround.

its one shape per secondary... however if you create a user shape instead of circles and squares, you should be able to assign the same shape to multiple secondaries.... I'm not in front of a machine right now, but nearly sure you can do this....

Ok, Thanks,
Applying the same shape to multiple secondaries wont help. I need to apply multiple different shapes to mask off areas of color in an otherwise desaturated image. It looks like i may have to use after effects i guess, unless anyone knows how this may be possible.

Yep, you can do that.

Are you sure you can't pull the color back up? If you completely remove color in one Secondary you should be able to bring it right back up using the Saturation controls in the next Secondary.
I've never taken anything to complete black and white in a grade so I'm not entirely sure this will work, but I have done some major desaturation in areas of the frame, and then push the saturation back up in other areas on the next Secondary Room.
As far as I know you can only apply 1 Vignette or User Shape to each room, keeping in mind that you control the Inside and Outside of each vignette so you do have a lot of control.
I'll have to play with this when I have some time and see what works and doesn't.

Then I guess grab all the color areas in multiple Secondaries and then grab your black and white areas in succeeding rooms.
Be sure to fill out a Color Feedback request for multiple masks in a single Secondary. Not sure if that's even possible, but you can always request it.

Hey,
This workaround seems to work:
1. Desaturate your entire image in primary in room to .1 (very desaturated, but not totally desaturated.)
2. In your secondary rooms, make your vignettes and boost the saturation inside. Note - using the slider you can only boost the saturation to 4. However you can type in numbers into the field much higher - way past where you will need to go. Do your corrections in your vignette.
3. In the primary out room, bring the overall saturation down a bit - so that the section that you almost entirely brought down in step one goes down more. This will also bring down the saturation in all your image, so you'll have to play around with saturation levels in your vignettes relative to primary in and primary out settings.
The key that will make this work is to type in higher levels of saturation in the secondary rooms than using the slider will allow. (try typing in 20 for example, and the saturation will be boosted by a large amount.

This has the feel of a rotoscope visual effect and is outside the application's intended scope as a colourgrade platform.
The secondaries room is somewhat limited with the one-vignette/one tab design -- you could have multiple windows in daVinci EDWin -- but it was the same (one only applied to all) correction inside all the windows.
Try building a node tree in the COLOR-FX room, so that you can keep pulling up a new instance of the original, qualify it in some way (although user shapes are not accessible in this room, you might discover some other way -- HSL?) and then alpha or blend it somehow back together.
If you insist on using COLOR to do something that I probably would do in Shake.
