202 Chapter 11 Inputs and Outputs

Controlling Tween Tracks Inputs can be used to control parameters of cues, similar to the way tween

tracks are used. This provides external control over most parameters. To use

this capability, add the desired type of tween track to the cue, then click the

formula button located in the header area of the tween track. You may need to

click the triangle in the tween track header to reveal the formula button. Some

tween tracks have multiple controllable parameters.

Clicking the formula button brings up a dialog box allowing you to enter the

control formula. By default, the formula consists only of the TweenValue item.

◆ NOTE: In order to access the formula of some tween tracks, such as Position,

Scale and Rotation, you must first enable this in the cue’s settings (see

“External Control of Position, Rotation and Scale” on page 178). For still

images, you must also select “More Effects and Capabilities” in the media’s

specification (see “Optimize For...” on page 36).

Some tween tracks, such as Position, contain multiple values, one for each

dimension controlled by the tween track (such as X, Y and X position).

The formula button allows you

to control a parameter using

an input. The button turns

ellow to indicate that such

control is in effect.

A red tween track

curve indicates that

the parameter is over-

ridden by a formula.
