clicking on its thumbnail. This highlights the clip with a yellow selection box and displays it in the Viewer. A
series of vertical film sprockets, running along the left side of the image in the Viewer, represents the first frame
of a clip (Figure 4.8). The same is true of a clip's last frame, which has sprocket holes displayed on the right
Figure 4.8 The first frame of a clip in the Viewer.
• To play a clip, use the Viewer's playback controls or press the Spacebar to start and stop the clip.
• To play a clip backward, press Shift+Spacebar.
• To play a clip from the beginning, press Control+Shift+I.
As the clip plays, a white vertical line in the clip's thumbnail represents the playhead position. This is independ-
ent from the skimmer's vertical line, and the two can be used in conjunction with each other.
• To move both the playhead and the skimmer to the start of a clip or selection, press Shift+I.
• To move the playhead and the skimmer to the end of a clip or selection, press Shift+O.
An even better way to play a selected clip is to use the J, K, and L keys. As mentioned in Chapter 2, the L key
plays forward, the J key plays backward, and the K key stops playback. But these keys don't stop there. Here
are some other useful actions that you can perform with these keys:
• Pressing the L key twice doubles the speed at which the clip plays.
• Pressing the L key multiple times increases the playback speed exponentially by the number of key
presses. The same is true of pressing the J key multiple times, except the playback is in reverse.
• Pressing the K and L keys together plays the clip forward in slow motion.
• Pressing the J and K keys together plays the clip backward in slow motion.
