Color correcting for Chroma Keying.

[Amadou]

I have chroma keyed a badly lit blue screen scene. Because the blue was not even, I chroma keyed sepate parts of the screen on different layers. So now the head of teh character is one one layer, masked out, and the body is on another layer masked out, and the two layers are on top of a third layer wich chroma keys everything else. The last layer is the background. By viewing all three layers at once, they give me a perfect key for the entire scene.

Now here comes the hard part:

How do I color correct all three layers in one common setting? In other words, is there a way to color correct the foreground composed of three layers without having to copy paste the same color correct setting on each layer? The reason I'm asking is because the copy-paste approach is a nightmare if I every want to make changes.

Thank you. rogar-BlackEye(DBG

Pre-compose those three layers.

You mean render against blue background? But if I render, I have to chroma kay again.

Go to the LAYER menu in the toolbar. At the bottom you'll see an item called "pre-compose". Click it.

Now you can work on the precomposed comp adding color correction, which will effect all layers included.

How do I undo a precomp?

Double click on it and it opens. If you then want to do away with precomp Copy those clicked on files and copy them into the comp. Then CTRL+X on the precomposed piece.
