Trimming
About trimming
You can
trim
(hide) footage at the beginning or end of a layer, changing which frames are first or last in the compo-
sition. The first frame to appear is called the
In point
, and the last frame is called the
Out point
.

point reference
When you use a footage item as a source for different layers, you can trim it differently in each layer. Trimming does
not alter the original source file.
Note:
Trimming a still image layer changes the length of time the image appears in the composition; it does not crop the
image (affect what portion of the image appears).
To trim layer footage
You can trim by changing the In and Out points in the Layer panel or the Timeline panel, depending on what you
want to change.
In the Layer panel, In and Out points relate to time positions within source files, not the time at which the layer
appears in the composition. For example, if you want to show only specific frames of a movie, trim the movie footage
in the Layer panel. However, if you want to begin the movie at the first frame in the source file and then cut it at some
point in the play time, trim the Out point in either the Layer panel or the Timeline panel.
The numbers below the layer image indicate the In point
and Out point
relative to running the source file, and
the duration (the difference between the In point and the Out point).
In the Timeline panel, the In and Out columns tell you at what points in the composition the footage appears. For
example, if you want a still image to appear at a specific point in the composition and then disappear again, trim the
image In and Out points in the Timeline panel.
Note:
If the In and Out columns do not appear in the Timeline panel, click the Expand/Collapse icon at the bottom of
the Timeline panel.
