Suppress greenscreen reflection on metalic surface
on Jul 26, 2013 at 8:33:11 am

Hi there everyone.

First, sorry for my English. It is not my mothertongue.

Secondly. I have a little problem and and i'm getting desperate. I've got clip shot in front of green. There are only hands holding a gun (like in 1st person shooter games). Gun is made from metal and whole green screen is reflected in it.







The question is, how can i get rid of the reflection on gun and key out the green screen?

Please, give me an advice.

Many thanks :)

Those answers work for keying. For suppression I recommend this:

The 50/50 split on Red/Blue in the Channel Mixer is a good starting place. You can adjust as you see fit but try to keep the sum as close to 100 as possible.

Note: you'll need to key and then suppress the green in that order :)
