298 Chapter 15 Geometry

Â Using a tracker: You can also use motion tracking to automatically animate a Pan &

Scan effect, for example, to move to follow a character who is walking across the

screen.

Once you create a tracker and analyze the shot (in the Tracking tab), you simply

specify the number of the tracker you want to use in the Use Tracker field, and the

Position X and Y parameters are automatically animated. If Use Tracker is set to 0, no

trackers are applied. For more information, see “Tracking Tab” on page 306.

Copying and Resetting Pan & Scan Settings

Three buttons at the bottom of the Pan & Scan tab let you copy and reset the

adjustments you make with these controls.

Â “Copy to Selected” button: Select one or more shots in the Timeline, and click this

button to copy the current Pan & Scan settings to all the selected shots.

Â “Copy to All” button: Copies the Pan & Scan settings to all the shots in the program.

This is useful if you’re making a global adjustment when changing the format of a

program.

Â Reset Geometry button: Resets all the Pan & Scan parameters to the default scale for

your project.

Shapes Tab

The Shapes tab lets you draw custom shapes to use as vignettes in the Secondaries

room for feature isolation, vignetting, or digital relighting. The Shapes tab is not meant

to be used by itself, nor are you meant to begin operations in the Shapes tab. Instead,

shapes are initially created by choosing the User Shape option from the Shape pop-up

menu of the Vignette controls in the Secondaries room.

When you choose this option, you are immediately taken to the Shapes tab of the

Geometry room, which provides the controls for drawing and editing your own custom

shapes. For a more thorough explanation of this workflow, see “Using a User Shape for

Vignetting” on page 225.

Note: User Shapes can only be used with secondary operations in the Secondaries

room. They cannot be used in the Color FX room.
