Animate Resize Settings
Animate the position of the crop box to pan and scan a 16:9 composition to
a 4:3 format. Pan and scan is a technique widely used for resizing 16:9
compositions to a 4:3 resolution when the area of interest in the shots is to
one side of the 16:9 frame. You can follow the area of interest in the shot by
animating the crop box along the X-axis.
To pan and scan a 16:9 composition to a 4:3 composition:
1 Drag the Resize tool from the Tools tab to the dependency graph in the
Schematic view, and connect it to the composition.
2 From the Destination settings area, select the 4:3 resolution to which you
want to resize the source.
3 Select a filter from Filtering.
4 Select the Crop Edges fit method.
5 Select Center and Keep Aspect buttons.
6 Select the Fit To Source button (in the Reference area) to make the crop
box the same size as the source frame.
7 Go to the first frame.
8 Make sure Autokey is selected so you can create position keyframes for
the crop box automatically.
9 Scrub through the clip to identify areas where the area of interest includes
the left and right edges of the clip outside the crop box.
10 Animate the position of the crop box accordingly by dragging the crop
box. You may also type the values into the respective X, Y, Width, and
Height attribute value fields—see
Setting Keyframes Automatically on
page 680.
11 Play the resized composition.
