I shot the following footage of an osprey nest (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. And third, stabilization using Mercalli 4.0 with Cmos correction. It seemed to work surprisingly well, although it's really slow. I would suggest using 4.0 only for such "problem" clips.
