Not sure quite how to describe this, but is there a plugin/ script that I would use to make a graphic of a person, and then an exponentially increasing number of people, 'pop-up', until they filled the screen, getting faster and faster.
It's a common effect that I'm sure you're familiar with, for showing a large/ increasing number of people through a graphic.
Many thanks for your help.
You could use the Card Dance effect or any other particle system that allows custom textures. Other than that it's merely a matter of animating a prototype or creating a pre-comp and duplicating it often enough with different timing, e.g. by enabling time-remapping.
