For something like this, I don’t think AE’s simple motion tracking will easily give the results you want. Here’s my thoughts ,but if you still want to use AE’s motion tracking, simple hold the ALT key and drag to a new object that’s in frame. AE will keep the offset tracking correctly.
1. virtualdub’s free deshaker is super easy to use and gives great results. It uses vectors to control the camera smoothing by filling in edges, and adaptive zooms. Really good programming.
2. Use Ae’s timewarp with pixel motion then precomp it and timestretch that to the same timewarp amount in the same fps. It will maintain the same fps but will smooth out any jerky movements.
