y Position move with hold keyframe

[Dan Ebberts]

Try this. Add sliders named “amount” and “delay” to your layer (be sure to set them to something other than zero) and apply this position expression:

amount = effect(“amount”)(“Slider”);
delay = effect(“delay”)(“Slider”);
t = inPoint;
y = 0;
while (t < time){ y += amount.valueAtTime(t); t += delay.valueAtTime(t); } value - [0,y]

Another thought regards this really good expression, if I may…

Can the delay slider work in frames per second? I am having trouble trying to accurately control it over time when its on a 0 – 100 increment.

This should make your delay slider work in frames rather than seconds:

amount = effect(“amount”)(“Slider”);
delay = effect(“delay”)(“Slider”);
t = inPoint;
y = 0;
while (t < time){ y += amount.valueAtTime(t); t += framesToTime(delay.valueAtTime(t)); } value - [0,y] Dan

I thought my head might explode trying to work that one out!

Thank you very much

Hi All, I have similar question?
I would like to do a stop motion animation.
My idea is skip frames using Hold keyframes.
Is it possible to do with expression?
I would like to apply this expression for rotation and position.
Regards, Fernando.

I’d start with posterizeTime(). You supply the desired fps. So, if you wanted 12 frames per second, it would be like this:

posterizeTime(12)

You’d apply it to each property you wanted to affect.

Hi Dan, I try insert your expression in rotation property but a warning massage appear.
I have 2 key frames start rotation and end rotation.
When I press Rotation stopwatch with option(alt) a small code appear.
I remove it and insert your code, but not worked.
Look the image.

transform.rotation

posterizeTime(12)

[Dan Ebberts]

Ah yes, sorry. Try this:

posterizeTime(12);
valueAtTime(time)

It works!
Thank you very much!
Time is money 😉
