    Moving background chromakey

    Posted by Anandabrata Ghosh on July 17, 2007 at 7:10 pm

    Hi,

    How do I make a moving clip a background matte for bluescreen. If I add one it becomes the predominant one since it’s opacity is 100%. Incase i reduce that is a simple overlay of all portions of the screen. but i want to use it as only the chroma matte.

    Please help.

    Regards,
    Anand

    Hi Dave,

    Thanks for your inputs. I meant just a moving image background, mentioned the matte by mistake.

    I got the problem. I was placing the simple clip on top of the bluscreen clip and hence the problem.
