Common 2D Effect Parameters
477
Grid
Grid defines the Effect Grid associated with an effect. Grid parameters set in the Effect Editor
override settings in the Grid Settings dialog box for that effect only. This parameter is not
keyframeable, and is not available in all project types.
Reverse
Animation
Reverses the entire effect, including the direction of movement as well as the incoming and
outgoing sources.
This maintains the shot continuity while reversing the movement. This option effectively
creates a mirror image of the sequence of keyframes for the effect as they appear in the Effect
Preview monitor’s position bar.
The Reverse Animation parameter is only available for certain effects that do not use advanced
keyframes. To reverse an effect that uses advanced keyframes, for example an edge wipe, use
the Reverse Keyframes shortcut menu command in the Effect Editor. For more information, see
“Reversing Advanced Keyframes” on page 110.
Invert Key Reverses the key as follows:
With a Chroma Key effect, displays the key color regions while showing the background
image source through the foreground image area.
With a Luma Key effect, displays the background image source through the darker areas
rather than the lighter areas of the foreground image source.
With a Matte Key effect, effectively reverses the black and white areas of the alpha channel
so that foreground and background are reversed.
Show Alpha Displays the grayscale alpha channel used to apply the key effect to the foreground and
background source. This lets you examine problem areas of the key while making adjustments.
