Apple Final Cut Pro 7 - Manual (Page 1032)

Logarithmic sliders are useful for parameters that have a huge range of possible values,
with a particular range at the top or at the bottom being more useful than the others.
Point Control
Point controls are used to specify locations in the Canvas.
To define a new location with x and y coordinates
1 In the Filters tab of the Viewer, click the point control.
Point control X and y coordinates
2 Move the pointer to the Canvas.
The pointer changes to the crosshair pointer in the Canvas.
3 Click anywhere in the Canvas to position a coordinate at that location.
Tip: You can also drag in the Canvas and then release the mouse button when the pointer
is at the appropriate location. If you drag instead of clicking, the values update as the
crosshair moves.
For more information about positioning clips in the Canvas, see “Using Cartesian Geometry
to Position Clips.”
Angle Control

the angle. The smaller, red hand indicates how many total rotations forward or backward
are specified.
Angle control
To constrain the dial to 45-degree increments
