Lesson 13. Warping > Compositing Outside Keylight

Compositing Outside Keylight

When the foreground item within the green screen requires color adjustments or transformations, it’s best to break the compositing out of the keying operations and use an Over node instead. To accomplish this, set the output to Unpremult (unpremultiplied). When selected, the key is knocked out of the foreground but then divided by its mask. This allows you to apply color corrections before compositing with an Over node.

Note

If you are applying only filters or transforms, you can set the output parameter to On Black.
