Using Property and Tracking Controls (PB only)
6 Define the feature region, search region, and track point, as described in “Defining
tracking regions” on page 396.
7 Click Options to define other tracking settings, as described in “Tracking a moving
region or object” on page 404.
8 In the Motion Stabilizer panel, click Analyze. Watch the tracking to make sure it is
accurate. If not, press any key to stop tracking, adjust the settings, and begin again.
Keyframes are not generated until you click Apply.
9 When you are satisfied with the track, click Apply to copy keyframes to the layer.
10 To stabilize one or more additional time ranges in the layer, follow the steps for
tracking multiple areas, as described in “Tracking a moving region or object” on page 404.
You can stabilize as many ranges as you need.
If the image creeps in from the margins of the action-safe zone, increase the scale just
enough to extend past the margins. Find the frame that creeps in the most, and then
nudge the scale (in the Composition window) using the Alt + + (plus) and Alt + – (minus)
keys on the numeric keypad (Windows), or the Option + + (plus) and Option + – (minus)
keys on the numeric keypad (Mac OS). This technique adjusts the scale for the duration of the
footage.
