Green Screen


The green screen in the Media Studio can be used when you want to replace your background in post-production. This article will go over the best way to light the green screen and ensure your post-production background looks its best.

Basic Recommended Setup

  1. The overhead lights are a different color temperature than the studio lights, and you cannot adjust their placement or brightness. You should turn them off before recording to achieve the best possible lighting for your shot.  
  2. The left and right front lights (LF and RF) light the green screen background. Turn on all three switches of the LF Light and RF Light.
  3. The left and right rear lights (LR and RR) light your subject. Turn on three switches on the RR Light and two switches on LR Light. The RR Light acts as the key light, or main  source of light on your subject, while the LR Light acts as the fill  light, which is a supplementary light used to lighten shadows.
  4. Position  the subject at or in front of Subject Line, centered in the shot. This  will reduce the amount of shadow created on the green screen. The more  shadow, the harder it is to key out the background when editing.
  5. Record your subject.

You may adjust the lights' placement, height, and brightness as you see fit. This is just a recommended setup for those unfamiliar with video production.
