CHroma Key Green Screen Pixelation

[richflorida]

I have been trying to insert an overlay of an instructor talking into a video. I have a green screen background and when I apply the chromakey option the background goes transparent as expected.

The overlay appears OK on dark backgrounds (white guy with black shirt on). On white backgrounds there is tons of noise on the subject. I have tried adjusting the color and it still looks weak and noisy.

Any ideas?

Thanks in advance. Rich

Lighting is key. However this might help http://youtu.be/XmnlCHowg_k

Thanks. The video did help clear up the image when I have a dark background but I still have too much noise with the white background. I am going to try blue screen. I think I have enough light on my subject (approx 800 watts of 5500K light).
