Blue Screen Effect

I've created some clips with a blue screen, and can't figure out how to chroma key the blue out on catalyst, what am I missing?

Thanks

V 4 are you using ?

if yes use colours Fx 06 Transparent color , then play with the 3 channels .

thanks

keying isnt as easy as it looks.

there are many pitfalls - and im talking about the postproduction side of these things.

Did you ever try in editing program?
