I am shooting in front of a green wall and I have a blue background window frame. When I choose green/blue screen, iMovie defaults to the green wall. However, I only want to screen out the blue in the window frame. Is there a way to only select the blue?
Thanks!
Hi,
The following quote from Apple’s online help menu might be of help to you.
“In the viewer, the clip shot against the green or blue backdrop has the green or blue removed, and the clip below shows through the areas that were green or blue, creating a composite image.
The color that iMovie removes is based on the dominant color in the frame at the position of the playhead when you choose Green/Blue Screen from the pop-up menu. If the frame below the playhead isn’t representative of the rest of the clip, you may need to reposition the playhead and reapply the effect.
To reposition the green-screen or blue-screen clip, drag it to a different spot within the clip, or to a different clip. You can also drag the ends to lengthen or shorten it.”

To Add to Rich's reply, you might have to put in a short section of just the window, then reframe like you want. Position the playhead to the zoomed window and do your bluescreen. Then you can trim the portion with the zoomed window.
imovie, change blue screen colour
