System information
1. From the Tools menu, choose Video, and choose Video Event Pan/Crop (or click the Pan/Crop
button on the video event). The Pan/Crop plug-in is displayed in the Video Event FX window.
2. Adjust the selection area to change the viewable portion of the event.
n To resize the selection box, drag the handles located around the perimeter of the box. To
type specific dimensions for the selection box, expand the Position heading on the left side
of the window and type new values in the Width and Height boxes.
Select the Lock Aspect Ratio button if you want the selection box to retain its aspect ratio
during resizing. When the button is not selected, the height and width can be resized
independently.
Select the Size About Center button if you want the selection box to retain its center
point when you resize the box by dragging its edges. When the button is not selected, the
opposite side of the selection box will remain anchored when you drag the edges to resize it.
n To reposition the selection box, click in the middle of the selection area and drag to a new
position. To type a specific location, expand the Position heading on the left side of the
window and type new values in the X Center and Y Center boxes.
When Move Freely is selected, you can move the selection box along the X or Y axis.
When Move in X Only is selected, you can only move the selection box horizontally.
When Move in Y Only is selected, you can only move the selection box vertically.
n To zoom in on the selection so the selection fills the output frame, expand the Source
heading on the left side of the window and choose Yes from the Stretch to fill frame drop-
down list. When No is selected, the media retains its original size, and the area outside the
selection box is cropped.
Right-click the workspace to display a shortcut menu that displays commands to restore,
center, or flip the selection box. You can also force the box to match the source media's aspect
ratio or your project's output aspect ratio. Matching the output aspect ratio can prevent black
bars from appearing when you use source media (such as photographs) that does not match
your project's aspect ratio.
3. The cropping or zooming occurs instantly and the results are updated in the Video Preview window.
4. If you want to create an animated crop or zoom, use the keyframe controller at the bottom of the
Video Event FX window to establish distinct zoom settings throughout the duration of the event.
During playback, intermediate frames are interpolated to create smooth motion. Expand the
Keyframe interpolation heading on the left side of the window and drag the Smoothness slider to
adjust the interpolation. For more information, see "Keyframe Animation" on page 294.
Use the Default Pan/Crop smoothness control on the External Control & Automation tab of the
Preferences dialog to set the default Smoothness value for new keyframes.
Creating a Bézier mask
Select the Mask check box in the keyframe controller at the bottom of the Video Event FXwindow and use
the controls in the Path heading on the left side of the Pan/Crop plug-in to create masks using Bézier
curves.
