The Sequence Presets Window
Audio/Video Settings, Sequence Presets Window
This window allows you to select an editing timebase for the current sequence.
Once you add a clip to the sequence this cannot be changed. By clicking in the
leftmost column (see the checkmark in the sample screen above), you select a new
Sequence Preset for use. The checkmark tells which Preset is in use—highlighting a
choice alone does not select it.
If you select an editing timebase you can then edit it (click the Edit button) or copy
and rename it as another (click Duplicate). When editing a timebase you can
change the following:
•
Select video processing properties (how to render)
•
Frame size and aspect ratio
•
Pixel aspect ratio
•
Field dominance (none, upper, or lower)
•
Editing timebase
•
Set QuickTime video codec settings (quality and type)
•
Select audio sample rate
