When music makes the video, discuss and recommend soundtracks for specific themes/subjects.
by Ron Hunter » Sun Nov 22, 2015 9:00 pm
The music director at my church has asked me to do some green screen filming to simulate people being in the Holy Land.
I have a 10'x10' bright green fabric but I'll never get all of the wrinkles out of it.
Do any of you have recommendations for green screen material?
The actors' costumes will be khaki colored. Does this mean blue screen is a better choice?
Any other tips?

Blue might be a better choice, but khaki is distinct enough that you can probably use green also.
Wrinkles are a major problem. You'll go nuts trying to work around the wrinkles in post-production. Also make sure you've got good, even lighting on the screen (and separate lighting for your actors). A hot spot or shadow can also make it difficult to get a good, clean chroma key.
In short, the smoother and richer that green backdrop, the easier time you'll have making the effect work.

Either blue or green will do fine. Try to light the backdrop evenly. Separate the actors from the background as much as you can to minimize color spill and shadows. Lighting the actors separately is a good idea and will also help to avoid color spill. Use a garbage matte on the clip to remove extraneous parts of the image to improve keying.

Thanks! Any suggestions for material type? My current green material is a large sheet of felt.

I recommend spending $20-40 on a real green screen. The material is non-reflective and it's a bright green color. http://www.amazon.com/6x9-Chromakey-Bac ... B001PCQTDOYou'll still have to iron it though.

Regarding the material, you might try throwing the green screen in the dryer that will help remove wrinkles. I also use some tablecloth weights on the bottom of my green screen to help keep the material tight and remove wrinkles.

In the link Steve provided there are pics of background holders. I used to use two light stands I already had, some really cheap, round curtain rods extended across the tops that I clipped to the stands with large, metal clothespin type clamps (think Lowes, Home Depot) and regular, wooden clothespins to hold the background in place.
Good luck with your project.

I agree with with Steve about possibly using blue. The more contrast not only in color, but also in value from your subject, the better off your separation will be. Another good deciding factor of your chroma key color can be based on what you know you'll be compositing on top of. If you're putting your subject in front a daytime scene, green is good because the lightness of daytime can hide the light color of green if it becomes visible around the edges of your subject, where as blue tends to be hidden better with darker backgrounds.
