The lesson

Chroma keying removes a green or blue background. Good results need even lighting on the screen and distance between the subject and screen.

Clean up spill (green reflected on the subject) and edges, and match the new background's light and colour.

Tracking makes a graphic follow movement in a shot.

Step by step

  1. Key the provided green screen clip.
  2. Remove spill.
  3. Add a background and match colour.
  4. Track a label to a moving object.

Practice activity

Create the green screen composite.

Expected result: A clean composite with matched colour.
