Hello,

I am shooting a pair of shorts on a green screen for a video I am making and am keying out the green using AE CS5 Keylight 1.2.

The problem is I am getting a lot of noise on the shorts. I have messed around with clipping the blacks and have even creating a garbage mask as an alternative but am still getting a good amount of noise on the shorts.

What is causing this? Any ideas?

Thanks!

Here's the image. I know it is not anywhere near perfect.

Oooh, that's going to be tough -- there is a LOT of green in those various hues of blue. I hope Kevin's suggestion works out for you.

This could be made even tougher if that image is shot on HDV as well.

it would be best if you could post an image that points out the noise, but if you're talking about what i think you're talking about, in the screen matte settings, set the replace method from soft color to hard color.

Kevin,

It it is hard to see the noise in an image you can really only see it when I play back the video but your suggestions worked and the noise is gone. Thank You!
