Need help with Green screen keying
I’ve filmed a little video on a green screen, when I add the green screen key the green disapears and the background becomes black.
I have the video in the video 2 spot, I created a white matte and brought it in on video 1 – it comes in grey – not white.
I’ve tried everything to make it white but it won’t go white – it just stays grey!
please help!

It sounds like your key wasn’t good enough to get rid of the green completely so its leaving some spill which would leave a gray spot. I usually key in after effects so I dont have any suggestions to help you clean it up any. Normally though its only gray on shadows and that sort of thing. Hope that helps some.

I haven’t got around to playing with the parameter on chroma key other than “precise” but it looks as if there is scope for a range of colours to be keyed – the problem then is if it pulls-in part of the wanted image and puts holes in the “person/object”
I do mostly still clips at present with chroma key but if it was video I would look at the lighting of the “screen” – shadows from the “object” will make it harder to work with if there is not enough strong light on the screen itself – say from both sides pointing behind the object (off screen of course).
