Hasta La Motion!

Hi there, I’m kind of new to nuke, but learning very quickly and really enjoying using the software, but I have a question about a certain production technique.

I was watching the following tutorials, and this one seems great for unwrapping an environment painting changes in photoshop and the re-wrapping onto a sphere within nuke, but the camera is in a fixed position only allowed to pan and not track:

This one seems great for painting out issues if the camera is a simple track (i.e. rig removal):

So my question finally is, how would you unwrap an environment from footage where the camera is both panning and tracking, so that changes can be painted and then re-projected, or am I totally going about this with the wrong method?

Thanks in advance

Arvind!
