Editing Video
Maintaining the original aspect ratio of a clip
A project can contain clips that have varying aspect ratios (proportions of height to width).
The aspect ratio of a project is determined by the frame size you specify in the Project Settings
or Export Settings dialog boxes. When a clip in the Timeline uses an aspect ratio that is different
than the project aspect ratio, Premiere stretches the clip to match the aspect ratio of your
project. However, this distorts the picture, so Premiere also lets you maintain the clip’s original
aspect ratio. When you maintain the aspect ratio of a clip with a different aspect ratio than the
frame, two sides touch the edge of the frame and empty space appears outside the other two
sides, similar to how letterboxed wide-screen videos appear on a television. Premiere lets you
specify the color for the empty areas. For more information, see “Aspect ratio” on page 344.
To maintain the original aspect ratio of a clip:
Select a clip in the Timeline, and choose Clip > Video > Maintain Aspect Ratio.
To set the color for frame areas outside a clip with a maintained aspect ratio:
1 Select a clip in the Timeline.
2
Choose Clip > Video > Aspect Color, specify a color (see “Using the Color Picker”
on page 253), and click OK.
Enabling and disabling clips
You can disable a clip in the Timeline. This is useful if you want to suppress a clip while you
try out a different editing idea, to shorten processing time when working on a complex
project, or to exclude a clip from an EDL you export. A disabled clip does not appear in the
Monitor Program view and will not appear in a preview or video file you export. If you have
not locked a disabled clip, you can still make changes to it. If you want to disable all clips
on the same track, you can exclude the entire track instead; see “Customizing track views”
on page 141.
