Keyframe Reset
button — used to control when images are frozen, only avail-
able when the Keyframe mode button is selected as the Strobe Type.

has the
Keyframe Reset
button on.
•

— does not change the frozen image at each keyframe
Force Strobe
— When an effect passes over or stops on a keyframe, a single
strobe event is triggered. While the effect sits on a keyframe with keyframe-
strobe on, no additional events are triggered. The "history" of the prior
single event is discarded, and a single strobe is triggered again.
•
ON
— accumulates a field/frame of video within the Output Recursive
loop.
•
OFF
— No action is taken.
