Building a Composition
The QuickTime and Video for Windows Footage windows do not display the effect of
settings made in the Interpret Footage dialog box, such as the alpha channel interpretation.
However, for any footage item that includes audio, the QuickTime and Video for Windows
Footage windows play the audio, while the After Effects Footage window does not.
To view the footage with more controls and information but without audio, view it in an
After Effects Footage window, where you can trim the footage and insert it into the
Timeline window. For more information about playing back, magnifying or reducing,
viewing the alpha channel of a footage item, and trimming video, see “Composition,
Layer, and Footage window controls” on page 53 and “Trimming layer footage” on
page 140.
To open a movie in the default Footage window:
Double-click a movie in the Project window.
To open a movie in an After Effects Footage window:
Press Alt (Windows) or Option (Mac OS) as you double-click a movie in the Project
window.
In the After Effects Footage window, you can trim the footage
and insert it into the Timeline window.
