Old Fusion user here who's done lots of successful trackings but something's weirdo this time:
I've got a quick pan shot of a car. I need to replace the license plate with a different one. I tracked the scene fine, but, when I take my replacement license plate graphic and try to connect it to my tracker, it seems no matter what I choose from the "Connect to Tracker: ___" list, the replacement license plate just doesn't move correctly with the tracker path-- it just "kinda moves". Also, I'm used to the thing connecting to the track jumping to a new start position as soon as the connection is selected (where I then simply make a single reposition adjustment with my Merge XY), but it's not doing it. Just sits there.
Anything come to mind as to what I'm doing wrong?
