System information
If you want to adjust temporal interpolation how motion occurs over time change a keyframe type by
right-clicking a keyframe and choosing a new interpolation curve type (linear, fast, slow, smooth,
sharp, or hold).
During playback, intermediate frames are interpolated to create smooth motion. For more information, see
"Keyframe Animation" on page 294.
Use the Default Pan/Crop smoothness control on the Editing tab of the Preferences dialog to set the
default Smoothness value for new keyframes.
Editing source media aspect ratio and stretching
Use the controls in the Source heading on the left side of the Pan/Crop plug-in to indicate how your video
will be stretched or cropped.
Item Description
Maintain aspect ratio Choose Yes from the drop-down list (or select the button) to
prevent distortion of the source media file.
When you choose No, the source media's ratio of height to width is
not preserved when video is stretched in the output frame.
Stretch to fill frame Choose Yes from the drop-down list if you want the media in the
selection box to fill the output frame.
When you choose No, the media retains its original size, and the area
outside the selection box is cropped.
Editing workspace display settings
Use the controls in the Workspace heading on the left side of the Pan/Crop plug-in to change the display.
