Hi everyone,

I have a camera with about fifty frames of baked animation from a 3D program. I need to find a way to take those baked keyframes and retime them. I know in Cinema 4D, there's something called the time track that allows you to retime pre-animated elements in a given scene. Is there anything similar in AE?

Thanks a bunch!

Create an expression control that lets you control the retime.

Create a duplicate camera, with no animation

Hook it up to the animated camera with an expression that references the position of the original camera, from the frame specified by the expression control.

Keyframe the expression control to do the retime.

The new camera will be able to get values from in between whole frames from the original camera based on the animation curve.

I don't have After Effects in front of me and haven't used expression in it for a while so can't give you an example but this is how I would set it up.
