Hi Pete, can you explain your problem a bit more, for example what nodes are you using, were you simply given a Transform / CornerPin node that has an animated matrix? There may be an easier way to achieve what you want.
The following is the "hard way". First go to your new reference frame 'f' and get that matrix, let's call it M. Now for every frame, get the matrix A, and post-multiply it by the inverse of M, and set that as your new A, e.g. A = A * M^-1. This is effectively warping everything by the opposite of whatever existed at 'f', making 'f' your new reference frame. For practical reasons, it might make more sense to save your matrix into a new Transform node so that you still have the original if you want. Hope that makes sense, Dan.
