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?
