hi signet
sorry for my late reply.. pretty busy
here's how i'm doing these shots with moving camera and moving objects:
i'm spliiting it up into one matchmove per moving group: first i'm tracking the camera and export it, then i'm tracking my object and export it seperately. now you just have to combine it in your 3d tool of choice (i'm using cinema 4d) and you're done
btw, there's a new shot in the gallery
hope to help,
basti
