There are multi-clip video effects, such as creating a cutaway, using a green/blue screen to cut out a subject and replace the background with a different clip, creating a split-screen, and picture-in-picture effect. IMovie includes options to modify and enhance video color settings, crop and rotate of a video clip, stabilize shaky videos, add video transitions (such as fade), and changing the speed (speed up or slow down) of clips. iMovie transcodes (‘optimizes’) HD video upon ingestion (‘import’) using this codec and stores it in the QuickTime file format (.movie).
