  1. Thanks Andy for your tutorial on Imovie greenscreen!!

    I have imovie 11, on a macbook pro. I’ve created title art in photoshop- type
    with a free-form black background following the contours of type, in order
    to isolate the type from any background behind the title art. In this image,
    I have made all the background behind the type-black contour shape greensceen green.
    Question: can I use the greenscreen effect in imovie 11 using a still, as I described it above?
    if so, what do I save the title file as, to import it into imovie? I’ve tried everything that I could think of, with no success. I want the title art to show the movie running behind it,
    depending on the greenscreen mask to allow background moving behind the type, etc.

    Thanks for your good work!!

  2. Peter, your green screen “footage” can be a still image like you describe. Anywhere that the image is green, the video in the background will show through (after you apply the green/blue screen effect). A PNG file works as should a JPG image.
