Hi Tomas, thanks for the reply!

Correct, I’d like to set the initial keyframes and have a loop that essentially extrapolates from there. In this case, each time the keyframes go from A to B, I want to make B = A/3, rather than the same numerical difference of A – B every time.

I’d like this to happen because I am creating a swipe-by style animation of photos. Every 40 frames, a photo “swipes off” to the left, yanking in a new photo from the right at a faster speed (crossing over the old photo fading off). Rather than animate every photo, I’ve set each photo’s X value to 3 times that of the preceding one, daisy-chaining them all to the first photo. However, this means I’m still manually keyframing each instance of X-axis movement on that first photo. Because each photo’s position is compounded on the previous one’s, the keyframes have to offset the change in X to 1/3 of the initial X value every loop.

Hopefully this gives a clearer picture of what I’m looking for; I’d be happy to post a screenshot of what’s going on in my timeline too, if that would help.
