The pixels that make up your footage have information about Luma, or brightness, and chroma, or color. If the subject is placed too close to the wall, or a rim light isn't used, it can create some difficult issues in post.Ĭhroma sub-sampling of your footage can also contribute to the issue.

One reason this can occur is due to bad lighting.

After doing the initial work to pull a key, the subject is often left with a green outline, or jagged edges. When you see the sheer amount of work that goes into big-budget film green screen work, it's no wonder that sometimes our own results may not match up to our expectations. Using chroma key in premiere pro, ultra key in premiere pro, and keylight in after effects, we'll fine tune those edges to get a great looking key. In this segment, we talk about fixing those rough and discolored edges that are often left after pulling an initial key. Green Screen work is complex, even under ideal circumstances, and working with footage that hasn't been shot properly can be pretty tough.
