Trim Settings Overview
You can customize how trimming works from the Trim Settings dialog box. The Trim Settings
dialog box has two tabs: Features and Play Loop. The Play Loop feature continuously replays the
last trim you performed for review purposes.
You can learn about specific Trim settings as follows:
• For setting some default behavior for trimming, see “Dual-Roller Trimming” on page 744.
• For information on transition playback loop parameters, see “Trimming During a Playback
Loop” on page 748.
• For information on dual-image playback during trims, see “Using Dual-Image Playback
During Trims” on page 748.
• For more information about the Play Loop feature, see “Reviewing Trim Edits” on page 746.
For information about all Trim settings, see “Trim Settings” on page 1440. For general
information on accessing and working with settings, see “Working with Settings” on page 1339.
You can also do the following:
• Map trim-related buttons onto palettes or the keyboard, as described in “Understanding
Button Mapping” on page 110.
• Configure a Trim-mode-specific Timeline view, as described in “Customizing Timeline
Views” on page 668.
Timeline Trim States
When you trim using the Timeline palette, the kind of edit you can perform depends on which
trim tools you select and the position of the mouse pointer relative to the transition you want to
trim. If you enable both the Overwrite Trim and Ripple Trim tools and then hover the pointer
over the upper half of your clip, you can perform an overwrite trim edit on either the outgoing
frames (A-side) or the incoming frames (B-side). When you hover the pointer over the lower half
of your clip, you can perform a ripple trim. Positioning the pointer over the transition between
clips lets you perform a dual-roller trim.
When you select one of the trim tools on the Timeline palette, you can perform only that type of
trim on your sequence.
The trim edit buttons also appear on the Smart Tool tab of the Command palette, so you can map
them to the keyboard, a toolbar, or the Tool palette. For more information on mapping buttons,
see “Mapping User-Selectable Buttons” on page 112.
