I shot the following footage of an osprey nest last summer (1080 60P) with a Panasonic FZ200 handheld at a 600mm focal length (full zoom). First, the original footage. Second, stabilization with Mercalli 2.0 with the rolling shutter compensation box ticked. Third, stabilization using Mercalli 4.0 with CMOS correction. And fourth, stabilization using the Rock Steady camera model. The CMOS correction seemed to work surprisingly well, although it's really slow. While the Rock Steady model works, it requires quite a bit of zoom. I would suggest using 4.0 only for such "problem" clips.
