Stretching Tween Tracks
Opacity
Volume
Position
When changing the length of a cue using its duration drag bar, you have the
option of either leaving its tween points at their current time positions or
making them expand and contract with the cue, as if the cue was a rubber
band. Press the Alt key during the drag to get the rubber band effect.
Use an opacity tween track to fade objects in and out, or to make objects semitransparent.
To cross-fade from one image to another, you only need to fade
the opacity of the front-most image. You don’t need to do anything to the
image behind it, as this will be obscured by the front image.
There is one exception to the above rule. If the image contains transparent or
semi-transparent areas, the back image will show through (see “Transparency”
on page 61). In this case, you may also need to fade out the image below to
perform a smooth cross-fade.
An opacity tween track can be applied to still and moving images.
Use a volume tween track to control the volume of sound files and movie files
containing embedded sound. You can play several sound files simultaneously,
and cross fade between them by fading up one while fading out the other.
Use a position tween track to make an image move along a path on stage. To
make the image move to a specific stage location, first go to the desired time
position, then drag the image in the Stage window to that location.
◆ NOTE: To change the initial location of the image for the cue, make sure
the timeline is positioned at the very beginning of the cue before dragging
the image in the Stage window. If not, a new tween point will be added instead.
To ensure that the timeline is positioned at the beginning of the cue,
first de-select all cues by clicking in an empty track area, then click the cue.
