Chapter 5. The QuickTime Standard Controllers > Varying a Movie’s Playback Rate

Varying a Movie’s Playback Rate

You can play a QuickTime movie in fast or slow motion, forward or backward, by using a hidden interface element. (This is something you can’t do in QuickTime Player.)

To vary a movie’s playback rate:

1.
Hold down the Control key (Mac OS) or Alt key (Windows) while you click either step button.

The step buttons disappear, and you’ll find your pointer atop a tiny white indicator in a tiny slider (Figure 5.6).

Figure 5.6. If you hold down the Control key (Mac) or Alt key (Windows) while clicking either step button, a tiny indicator and sliding area appear. Move the indicator all the way to the right to play the movie at 2 1/2 times normal playback speed.


2.
Move the pointer right or left.

The indicator moves, and the movie plays at different rates:

  • When the indicator is moved all the way to the right, the movie plays at 2 1/2 times normal playback speed.

  • When the indicator is three-quarters of the way to the right, the movie plays at normal speed.

  • When the indicator is slightly to the right of center (Figure 5.7), the movie plays in slow motion.

    Figure 5.7. Move the indicator slightly to the right of center for slow-motion playback.


  • When the indicator is in the middle, the movie pauses.

  • When the indicator is slightly to the left of center, the movie plays backward in slow motion.

  • When the indicator is all the way to the left (Figure 5.8), the movie plays backward at 2 1/2 times normal speed.

    Figure 5.8. Move the indicator to the left of center for backward play.
