Calculating length and speed
on Sep 5, 2014 at 10:32:15 am

Is there a way to somehow determine mask path's length? I'm working on write-on alphabet and to control the dynamics I would need all letters to be revealed in the same speed.

For example path for letter "i" is obviously much shorter than for "S" or "W". I could easily set that both - "i" and "w" is revealed in equally long time - say 15frames, but in that case the revealing animation would be really fast for "w" and fairly slow for "i". I want speed to be constant - meaning it would take 15frames to reveal i, but to reveal "w" it would take ~40frames as the shape of "w" is roughly 2.5 times longer than the shape of "i".

Is there a way to somehow calculate this using expressions or at least measure the speed visually to get the roughly identical speed?

just found this post. Did you ever find a solution for this?

Not particularly automatic, but the first thing that comes to mind is splitting each letter onto its own layer at which point you can automate the trim paths to be the same length on each.
