I'm trying to create a composition that freezes the input movie-stream
a certain number of times over a given time-period (creating the
effect of a reduced frame-rate). The Accumulator node does the job of
freezing the image just fine, but I need to be able to set a minimum
time so that the Accumulator's 'Accumulate' parameter is always turned
on for a minimum of 1 frame. I'm currently finding that the
Accumulator is sometimes not switched on for long enough to 'catch' a
frame. This varies according to the frame-rate the composition is
running at and can lead to unpredicatable behaviour.
