add additional frames to tracked footage

So the brilliant editor I work with and his wonderful client decided that they wanted to add an additional 2 seconds to a shot I already tracked and composited for them. So I went and exported the new 48frames and tried to tack them onto the end of the footage already in my motion tracker (no need to add new point right?).

However, nothing is lining up correctly. I can’t seem to re-import the image sequence with the new frames.

Does anybody have any ideas of how to do this so I don’t need to re-track the whole scene?


I think you will have better luck getting an answer here…
