Ah! The old eval function! This is covered in some depth here:

But blink and you’ll miss the expression itself, so here’s a post with one that should work:

> [@3D Camera track retime expression](https://forum.logik.tv/t/3d-camera-track-retime-expression/772/4):
>
> Paste this expression into you new camera; eval (Camera, TW.Timing) Where “Camera” is your original tracked camera and “TW.Timing” is the Timewarp used to retime your tracked plate.

Good luck! It’s quite satisfying once you get it to work!
