Thanks for pointing me out the wiggle expression. I haven’t used it yet, but it will certainly come handy in future projects. However, in this particular project I ended up spending hours with tracking the background on the close-ups where needed, and then I applied all tracking info to a single null tracker, which I used as a parent for every background layer. The only trick I had to do is to reset the null tracker’s position with a keyfream each time the camera moved back to the static (tripod-shot) objects. I think this did the trick, however I still have to wait a night to see the end result in full resolution (it’s rendering right now). Anyways, thanks for the handy advice.
