Removing red from a portion of the frame...

[blando3]

I have a Final Cut Studio question regarding color correction. I have an interview that was shot with too much red on the background. The subject, to the right of frame, is just right, but the wall to the left needs some red pulled out.
Is there a way to select a portion of the frame and draw some color from only that? I know Photoshop has some tools like that...what about FCS?
Thanks,
Andrew

Use the 3 way color corrector in FCP. At the bottom of the effects controls there's a drop drown section for Limit Effect. Use the eyedropper in this section and sample the red portion you want to remove. You can adjust the selection with the chroma, luma and saturation sliders and also view the matte (e.g. what's being selected and what's not) by click the button with the trapezoid until it's a black and white icon.

Once you get the selection you want just adjust your normal color correction settings to pull out the specific red areas in your frame.

Yes, it s called 'garbage matte' located under: Effects--->Video Filters--->Matte--->Garbage Matte (there are 4-point & 8-point variations depending on how much framing control you want) Simply
1-duplicate your clip on a upper video track, (say the clip is on V1 track, duplicate it on V2)
2-add the garbage matte filter on the V2 clip and choose the area you want to color correct.(Bring the opacity of the clip on the V1 track to zero, so you can see what s going on the V2 clip)
3-add the color corrector filter to the clip on V2 and pull your saturation down
4- Put the opacity on the V1 clip back to 100 percent.
5-Fine tune.

Use the 3 way color corrector in FCP. At the bottom of the effects controls there's a drop drown section for Limit Effect.

Yes it is a good solution too, however if the person and the background share similar color features (like same shade, saturation etc) 'Limit Effect' will be expanded to those areas you are trying to protect.
Best solution would be to combine the garbage matte(and keying if there is any movement) & 'limit effect' options depending on the problem.

It's much easier to do it in Color - create a mask in Secondaries, then key the red and pull the saturation down. I don't like using the selection tools in the FCP 3-Way Color Corrector, you would have to create a garbage matte to isolate a portion of the frame and the process just gets too kludgy for my tastes. Grading suites were built for this sort of thing.
