Shuttling the Video Track
Shuttle Lock mode lets you use the numeric keypad to shuttle a video track and one or two audio tracks forward or backwards at specific speeds. Numbers 0 through 9 provide progressively faster speeds, as follows:

To increase the speed progressively towards normal speed, press numbers 1 through 4.
*   
*   
To increase the speed progressively faster than normal speed, press numbers 6 through 9.
Only the main video track is shuttled. When multiple audio tracks are selected, only the first two tracks are shuttled.
To play the video track with the shuttle lock:
1 With Pro Tools HD, make sure the Operation preference for Numeric Keypad mode is not set to Shuttle (see Operation Preferences).
2 Make sure the Video Online button in the video track you want to scrub is set to an online (blue) status.
3 With the Selector tool, click in the audio track where you want playback to begin. To shuttle on two tracks, Shift-click in a second audio track.
4 Press the Start key (Windows) or Control (Mac) and a number on the numeric keypad: 0–9 (9 is fastest, 5 is normal speed, and 0 stops shuttling).
Once Shuttle Lock mode is initiated, Fast Forward and Rewind become highlighted in the Transport window.
5 Press additional keys to change the playback speed, or press Plus (+) or Minus (–) to switch the playback direction (plus for forward, minus for backward).
