Chapter 3 Making and Editing QuickTime Movies With QuickTime Pro 21

Saving a Still Image From a Movie

If you have QuickTime Pro, you can export a single frame from a movie as an image file.

To save a still image from a movie:

1 Move the playback head to the frame you want to export.

2 Choose File > Export.

3 In the Export pop-up menu, choose “Movie to Picture” to save the image as a PICT file.

To export every frame from the movie as a series of images, choose “Movie to Image

Sequence.” Exporting every frame can generate a very large number of files; you may

want to export to a folder rather than to the desktop.

Working With Movie Tracks

A QuickTime movie is made up of one or more “tracks.” Each track stores a particular

kind of data. For example, a QuickTime movie could have a video track, music tracks,

and sound effects tracks.

If you have QuickTime Pro, you can use QuickTime Player to edit tracks individually. You

can move tracks from one movie to another, turn a track on or off, delete tracks, or

modify the information contained in a track.

Viewing QuickTime Movie Tracks

With QuickTime Pro, you can see the tracks in a QuickTime movie.

To see the tracks in a movie:

1 In QuickTime Player, choose Movie > Get Movie Properties.

The movie’s tracks appear in the left pop-up menu.

2 To extract or remove a track, or to turn a track on or off, use the track commands in the

Edit menu.
