Posterize Time effect
The Posterize Time effect locks a layer
to a specific frame rate. It’s useful on its own as a special effect,
but it also has more subtle uses. For example, 60-field-per-second
video footage can be locked to 24 frames per second (and then field rendered
at 60 fields per second) to give a filmlike look. Also, nested compositions
can be locked to a given frame rate. This effect is sometimes called Strobe in
hardware devices.
