Using the Trim Tools
Trim tools provide region, note, and data trim-
ming functions. The following Trim tools are
available:
• Trim tool; also called Standard Trim tool
• Time Compression/Expansion Trim tool;
also called TC/E Trim tool
• Scrub Trim tool (Pro Tools HD only)
• Loop Trim tool
The Trim tools are constrained by boundary re-
gions, regardless of the current Edit mode, as fol-
lows:
• Trimming towards the left is constrained
by the next region’s left-most boundary (re-
gion start).
• Trimming towards the right is constrained
by the region’s right-most boundary (re-
gion end).
• The Trim tool provides special functions
when used on looped regions and region
groups. For more information, see “Region
Groups” on page 452 and “Region Loop-
ing” on page 461.
Trim Tool
With the Trim tool, you can quickly shorten or
expand a region (up to the entire length of the
source audio file). The first time you trim a re-
gion, Pro Tools automatically adds it to the Re-
gion List as a new region (with a name derived
from the original) in order to differentiate it
from the original.
The Trim tool is a nondestructive tool and does
not actually modify the original audio or MIDI
data (when working on regions). To return to
the length of the original region, drag it from
the Region List, or resize the edited region with
the Trim tool to its original length.
