• Fields dominance of the format
• Aspect ratio to determine the pixel ratio for the specified file
• Key to determine how the alpha information in the image is used. If you select No
Alpha, then the movie’s alpha channel is ignored making the image 100% opaque.
If your movie file's alpha channel is premultiplied with a color other than white or
black, set the alpha channel to Straight Alpha and use the Premultiplied Alpha Key
filter to remove colored edges after the file is imported. See “About Keying” on
page 273.

movie respectively.

Importing Audio Files
As with movie files, you can import audio from the timeline or the Project window and then
drag to the timeline. Once on the timeline, you can scrub through and synchronize your
effect with the audio. You can also animate volume and balance information using unlimited
keyframes.
