Chapter 7: Playing and Editing the Movie Track 47

Sync Points

Sync points are used when a point within a re-

gion must be aligned to the Grid or to a particu-

lar SMPTE or bar and beat location. This capabil-

ity is important editing music and sound effects

for video and film work.

Once you have a sync point identified, you can

spot edit the clip based on that sync point. For

more information on moving video clips, see

“Moving the Movie Track or Video Clips” on

page 45.

To identify a sync point:

1 Set the Edit mode to Spot mode.

2 With the Selector, click in the region at the

point where you want to deﬁne the sync point.

3 Choose Edit > Identify Sync Point. A small

down arrow appears at the bottom of the region,

indicating the location of the sync point.

To remove a sync point, select the entire region

with the sync point and choose Edit > Remove

Sync Point.

For more information on sync points, see the

Pro Tools Reference Guide.

Locking the Movie Track

Ifyou want to permanently associate your video

clips with a certain location on your Movie

track, you can lock it in place so it will not be

moved accidentally.

To lock the Movie track:

1 With the Grabber, select the Movie track.

2 Choose Edit > Lock Region/Unlock Region.

When the Movie track is locked, a small lock

icon appears in the track, indicating that the

Movie track has been locked and cannot be

moved. If you attempt to move a locked region,

you will receive an error message.

Once a Movie track is locked, you cannot Add

video clips to it (without first unlocking it).

Locking the Movie track only prevents it from

being moved. Recording still affects the clips in

the Movie track.

You can also lock the Movie track by triple-

clicking in the Movie track (to select all

clips) and pressing Command+L.
