Time filters manipulate layers temporally. Time filters are most often used to modify moving footage.
There are five Time filters:
Echo leaves a streaking trail behind the moving areas of an image.
Scrub allows you to change the timing of the clip without moving it in the Timeline, via a virtual playhead.
Strobe strobes the image, resulting in moving images that appear to skip frames as they play.
Trails draws light or dark trails following a moving image.
WideTime stretches the image’s motion out in time.
