Animate based on duration

[Duane Walters]

This has to be a terribly simple thing, but this is day two looking for anything of value and I’ve come up short.

Manually: slider control and you set a keyframe of zero at the beginning and at the end set it to 24 (but this number changes).

Expression: no matter what you set the end goal of that slider to, it always finishes at the end of the comp.

I came up with this, I just feel like there’s probably a more simple way of doing this?

linear(time, inPoint + 1, outPoint – 1, 1, effect(“Time”)(“Slider”));
