I have two objects moving in a simple way. They are two squares. They move from one place to another, and also change scale from 0 to 100. The start and end points for this position/scale animation, for each object, are synced.
THEN, after a few seconds, each object does a reverse move, back from the position it ended on in the first move, to it's first position of the composition. From 100 to 0 scale.
The first move works. Second move, one of the objects does a little dosie-doh, a little jerky jerky, before it starts it's move. The other object acts as it should.
I have made sure that the keyframes for each move are set to linear. For each move, the first position is set as Ease-out, and the second position is Ease-in. I have double checked that each animation has the keyframes set the same for each object. Like I said, both objects animate the way they should on the first move, then the second on, which is a reverse of the first one, just one of the objects moves in error before continuing the path it should.
This problem has plagued me in After Effects for a decade, and I've never had someone be able to explain why it actually happens. I guess they think it would go over my head, but if it is indeed not a bug, I would like to know why this is happening with this piece of software.
