Learn how to use QuickTime Pro to edit movies, manipulate movie tracks, and much more.

Simple Editing

With QuickTime Pro, you can perform movie-editing tasks.

Selecting and Playing Part of a Movie

To perform editing functions such as Copy and Delete, in most cases you need to first select the desired portion of a movie. (If you don’t select anything, the edit commands work on the current frame.)

To select a portion of a movie, move the In and Out selection markers. The darkened area between the two markers indicates the selected portion. To fine-tune the selection, select a marker and move it with the arrow keys. You can also move the playhead and press I (for In) or O (for Out) to set the start or end point of the selection, even while the movie is playing.

Tip: To move the In or Out marker to a different position, drag the playhead to the desired position (or use the arrow keys), then press I or O.

To play the selection, choose View > Play Selection Only (so that the checkmark appears), then click Play. To play the whole movie, choose View > Play Selection again (to remove the checkmark).

With QuickTime Pro, you can save the movie (choose File > Save) so that the next time it is opened, only the part you selected plays.
