by clicking and dragging. When you've finished, click the Done button, and
then close the file to bring up a Save dialog box.
Note that, prior to merging movie files, you should ensure they're the same
resolution (that is, both are 720p, for example). If you merge two or more
movie files of differing resolutions, the smaller file(s) will be proportionally
upscaled to fit the resolution and frame size of the larger movie.
Saving an Edited Movie
When you've finished trimming or merging movie files, click File→Close. This
will bring up a prompt asking whether you want to save the file. Unfortunately,
it's not usually possible to simply save the file in its original format. Instead,
it must be exported in an Apple-compatible format. The safest bet to retain
as much of the movie's quality as possible is to select the highest-resolution
output choice you're offered in the Format drop-down list: 1080p, 720p, or
480p, unless you know the movie has a smaller frame size.
