Chroma Key Environments

Overview:

Chroma keys can be recorded indoors or outdoors.

Indoor Environments:

Local and national weather television shows, TV commercial and industrial video production houses, and “A” and “B” movie productions use indoor chroma keys every day.

(1) Indoor keys are most commonly used by local and national news facilities to present their weather segments. The weather anchor usually stands within six to twelve inches of the green or blue screen (chroma key), while looking at a monitor directly left or right of the key screen, as well as a monitor that feeds into the teleprompter. The anchor will touch the screen at points that line up with cities, states, countries, or bodies of water that match the maps or radar being feed into the key.

(2) Indoor chroma keys are often times used to create complete television commercials and industrial productions. Here, the actors are placed in front of chroma key screens that are maybe 3’ x 4’ and up to the size of one or two airplane hanger walls.

(3) Indoor chroma keys are very popular in the movie industry. It’s probably safe to say that nearly all action, science fiction, or fantasy movies are shot using chroma key for several scenes. Just like #2 above, their chroma keys range in size.

Outdoor Environments:

A good number of documentary video production facilities shot chroma keys outdoors. Outdoor chroma key shooting can prove challenging, but doing so might save a good deal of time and money if it works. A portable chroma key screen is used to provide the instant background.
