Program Monitor on the next loop. Continue to adjust and review the edit until you are satisfied with the trim.
Move on to trimming the next edit point by using the Go to Next Edit Point or Go to Previous Edit Point shortcuts (the Up Arrow, and Down Arrow
keys), or stop playback, if you have finished.
Use the following techniques to refine your trim:
Use the Trim Forward and Trim Backward buttons to trim by one frame at a time. The keyboard shortcuts for trimming forward or backward
by one frame at a time are as follows:
Press Ctrl+Left to trim backward. Press Ctrl+Right to trim forward (Windows).
Press Option+Left, to trim backward. Press Option+Right to trim forward (Mac OS).
Use the Trim Forward Many and Trim Backward Many buttons to trim by multiple frames at a time. The keyboard shortcuts for trimming
forward or backward by multiple frames at a time are as follows:
Press Ctrl+Shift+Left to trim backward. Press Ctrl+Shift+Right to trim forward (Windows).
Press Option+Shift+Left, to trim backward. Press Option+Shift+Right to trim forward (Mac OS).
Use the numeric keypad "+" or "-" offset entry to trim by the specified numeric offset.
Use the Apply Default Transitions to Selection button to add the default audio and video transitions to the edit point.
Use the Edit > Undo and Redo menu commands or shortcuts to change the trims during playback.
A typical editing workflow would be to first assemble the sequence using insert and overwrite edits. Then, refine your trims by moving from one
edit to the next in trim mode, using shortcuts.
Trim tools in trim mode
Within the trim mode interface, and when playback is paused, use any trim tool, including the Selection tool, to drag across a clip to trim. If you
drag over either clip, a ripple trim is performed. If you drag between the two clips, a rolling trim is performed. If you drag the Selection tool with the
Ctrl key (Windows), or Command key (Mac OS) held down on the outgoing clip, a regular trim is performed on that side of the edit. If you drag with
the same modifier key held down on the incoming clip, a regular trim is performed on that side of the edit.
The behavior of dragging across clips in trim mode on the edit point is the same as it is with the trim tools in the Timeline. Dragging to the left
trims backwards, and dragging to the right trims forward.
Exit trim mode
Trim mode requires that at least one edit point is selected and that the playhead is positioned at one of the selected edit points. Any action that
clears the edit point selection or moves the playhead away from an edit point exits trim mode.
To exit trim mode, do one of the following:
Click the Timeline.
Use the Sequence > Trim Edit menu command, or press the T key.
Close the Program Monitor with a menu item, keyboard shortcut, or workspace panel operation.
Scrub the playhead, or use any other Timeline or Program Monitor navigation command that moves off a selected edit point such as Step
Forward or Step Backward.
Select or drag clips, or select or change any other object in the Timeline.
Switch focus to another sequence.
Keyboard shortcuts for trim mode
The Play/Stop Toggle keyboard shortcut starts or stops the playback. It is available when you are in trim mode, and defaults to the Spacebar
key.
Use the Trim Forward and Trim Backward shortcuts to trim by one frame at a time.
Use the Trim Forward Many and Trim Backward Many shortcuts to trim by the Large Trim Offset frames at a time (the default is set to five
frames). The Large Trim Offset value can be changed in Edit > Preferences > Trim (Windows) or Premiere Pro > Preferences > Trim (Mac
OS).
