Locking Clips

You can lock a clip so that it can’t be accidentally modified or deleted. You can lock the clip’s position and/or its data.

To lock or unlock a clip’s position and/or data

In the Clip Properties Inspector, select the Properties section, click the Lock field and choose what clip attributes you want to lock:

Position and Data. This choice locks position and data, and causes a lock icon to appear on the clip .

Position Only. This choice locks position only, and causes a yellow lock icon with the clasp unlocked to appear on the clip .

Data Only. This choice locks data only, and causes a blue lock icon with the clasp unlocked to appear on the clip .

Figure 157. The Clip Properties Inspector.

Or

1.	Right-click a clip.

2.	From the pop-up menu, choose one of the following commands:

Clip Lock > Lock Position. In lock mode, this choice locks position only, and causes a yellow lock icon with the clasp unlocked to appear on the clip. If data is already locked, then both position and data become locked, and a “locked” lock icon appears on the clip. In unlock mode, if both position and data are locked, and you unlock position, then the blue “unlocked” lock icon appears on the clip, meaning that only data is locked.

Clip Lock > Lock Data. In lock mode, this choice locks data only, and causes a blue lock icon with the clasp unlocked to appear on the clip. If position is already locked, then both position and data become locked, and a “locked” lock icon appears on the clip. In unlock mode, if both position and data are locked, and you unlock data, then the yellow “unlocked” lock icon appears on the clip, meaning that only position is locked.

Note: If a clip’s position is locked, and you change tempo, what happens to the clip’s position depends on what option the Clip Properties Time Base field is set to: Musical (M:B:T), or Absolute (SMPTE). If the clip is set to the Musical time base, the clip’s M:B:T position stays constant, and its Absolute position shifts. If the clip is set to the Absolute time base, its Absolute position does not move, but its M:B:T position shifts.
