Keyframe with value offset
Hello, hope everyone doing great!
I have 3 animated position keyframes (or maybe more) that have to be linked with 3 different sliders as an offset for the position,
1. keyframe 1 -> Offset position 1
2. keyframe 2 -> Offset position 2
2. keyframe 3 -> Offset position 3Is there any way to do this?
Thanks,

With linear keyframes, a position expression like this should work:
n = nearestKey(time).index;
if (time < key(n).time)n--;
if (n < 1){
key(1).value + effect("Position 1 Offset")("Point").value;
}else if (n == numKeys){
key(numKeys).value + effect("Position " + numKeys + " Offset")("Point").value;
}else{
offset1 = effect("Position " + n + " Offset")("Point").value;
offset2 = effect("Position " + (n+1) + " Offset")("Point").value;
linear(time,key(n).time,key(n+1).time,key(n).value + offset1 ,key(n+1).value + offset2);

How about when I have ease in the keyframe? that’s also different?

If the ease is AE’s standard easy ease, and you use it on all keyframes, you can probably just replace linear with ease in the expression. If it’s custom easing, that’s a different story.

Alright I got it, thank you so much Dan, as always!
