I want to write a script that would convert velocity from vegas to time remapping after effects. To do this, I need the value of the velocity on each frame. I'm interested in what formula the graph of the velocity is transformed by, with the envelop modes fast, slow, smooth. Using this formula, I would find out what value the velocity between two points has (screenshot 1).
(screenshot 1 - What is the velocity here?)
I'm weak in math, so I thought "what if I add a velocity point myself." But here's the problem: to add a velocity point, you need to specify the value of the velocity point in the constructor.
What are your thoughts on this. Maybe you know how to define the formula, or have ideas on how to add a velocity point without value yourself. I will be glad for any help.
