Defining the Play Range
Ordinarily, clicking the Play button plays your project from the first frame until the last.
However, you can change the area of your project Motion plays by modifying the In
and Out points in the Timeline ruler. You might do this to focus on a particular section
as you fine-tune your project or make other changes to it. Once you’re done focusing
on that section, you can reset the In and Out points to the beginning and end of your
project.
To customize the playback In point, do one of the following:
m
In the ruler, drag the In point marker from the left edge of the ruler to the frame where
you want to set the In point. As you drag, the playhead also moves with your pointer.
When you release the mouse button, the playhead snaps back to its previous position.
m
Choose Mark > Mark Play Range In in the menu bar.
m
Press Command+Option+I.
Note: Before you choose the menu item or keyboard shortcut, be sure that no objects
are selected in the Timeline. If an object is selected, any command modifies the objects
instead of changing the playback markers.
