Locked Tracks
Trim operations with the Ripple tool will only affect clip items on unlocked tracks. If
there are clip items on certain tracks you don’t want to change inadvertently while
trimming, you can lock these tracks in your sequence to prevent unwanted changes.
Linked items on locked tracks aren’t affected when you move other linked clip items. For
example, if you select a video item to trim that’s linked to an audio item in a locked track,
moving the video item does not move the audio item, so they become out of sync.
For more information, see “
Locking Tracks to Prevent Edits or Changes
” on page 314. For
information about synchronizing clip items, see Chapter 29, “
Tips for Edits Made With the Ripple Tool
Using the Command Key to “Gear Down”
The Command key is useful if you want to make very small changes to edit points or
clips in your sequence. When you drag clips or edit points to perform trimming
operations, the ratio between the motion of your mouse and the motion of the item
you’re changing is determined by the zoom level of the Viewer, Canvas, or Timeline. If
you have trouble trimming to a specific frame because you’re zoomed out too far, you
can force this motion to be a more precise 1-to-1 ratio (regardless of your zoom level)
by pressing the Command key after you start dragging.
For example, holding down the Command key after you start dragging an edit point
with the Roll tool makes the edit point move much more slowly as you drag.
Selecting Edits and Clips to Trim
Regardless of where you actually trim your clips, you almost always select the edit
points in the Timeline. Selecting an edit point is a lot like selecting an entire clip, except
that you are only selecting a clip’s In point or Out point, or the Out point and In point
of two adjacent clips. If linked selection is turned on, any edit points or clips that are
linked to the one you select are selected as well.
