Now, follow the steps outlined below to restore the foreground with a holdout mask.

1. The diagram below is a foreground camera view consisting of a teacher presenting the slides

using a TV.

2. As shown in the diagram below, the green components in the pictures and the title of the slide

shown against a green rectangle at the bottom left corner of the TV are incorrectly removed

after chromakey is applied. If left uncorrected, the background image will show through the TV

in these areas.

3. In these cases, you can mask the part of the subject that is incorrectly keyed with a holdout

mask to restore the original image. On the UI, open the Holdout Mask page, and adjust the

mask edges to cover the TV area.
