Trimming with the Timeline Palette
You can perform trim edits by using the trim tools on the Timeline palette. This lets you create
trims quickly in your sequence which you can later fine-tune by using the advanced functionality
of trimming.
You can make the following basic kinds of trim edits using the Timeline palette:
• Overwrite trim — single-roller trims which either add black or overwrite frames while
trimming
• Ripple trim — single-roller trims with no sync lock
• Dual-roller trim — edits that move the transition boundary between segments without
affecting the duration of the sequence
Some trims, such as overwrite trim edits, maintain sync between video and audio clips. Other
trims, such as ripple trims, might break sync. For more information on keeping video and audio
clips in sync, see “Maintaining Sync While Trimming” on page 751.
The following limitations apply to trim edits:
• You cannot trim a clip so that its duration equals zero frames.
• You can only trim until you encounter another segment in the same track. If you trim
multiple clips, you can trim until any of the transitions encounters a segment in the same
track or until the reach the duration of the shortest clip in the group.
• You cannot perform an overwrite trim beyond the duration of the selected clip.
Understanding Trim Displays
Different trim displays provide unique sets of controls for fine-tuning edits with various trim
procedures. You can perform many of the same functions from any of these trim displays, such
as removing and adding frames or slipping and sliding segments. For information about
accessing these modes, see “Trim Settings Overview” on page 736.

You can render transition effects while trimming, but you cannot render segment effects once you
select a transition for trimming. If the position indicator is on a segment effect or if the marked
portion of your sequence includes a segment effect, you cannot access Render menu commands
and buttons.
Small Trim Display
Small Trim display leaves the monitor display intact and has smaller displays of outgoing and
incoming frames.
