OT: Mercalli 4.0 Rolling Shutter Compensation

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.

The third example is not rock steady (as with a tripod), but seems free from interrnal wobble. What happens if you try to stabilize it so that it is rock steady?

I re-stabilized using rock steady and have included that clip in the YT video in my original post. It works, but requires quite a bit of zoom.

Amongst Prodad's list of the NEW for Merc4 is the detail for the CMOS correction and the actual approach what they've used. Along with the lens manufactors, proprietary Lens Fisheye correction list, made me want to make use of the then upgrade offer. Also Prodad's refreshing willingness to deal with new capture technologies.

Here's ProDad's list for Mercalli 4

"What is new in Mercalli V4 SAL? The latest additions to Mercalli V4 SAL at a glance:
• Unique and completely automatic CMOS correction for skew, wobble and jello
• Greatly improved video stabilization, faster and more efficient than ever!
• Improved stabilization, optimal perspectives (3D X, Y, and Z-axis stabilization)
• Optical-Warp-Image-Stabilize-Function (Fisheye-Distortions have no negative effect anymore
on stabilization process
• Because the Fisheye-Effect doesn ́t need to be removed before stabilization rendering is faster overall and less zoom is needed
• Numerous cameras are supported. Universal profiles included as well.
• Dynamic Zoom Reduction (significantly reduces the need to zoom-in)
• Improved border-boundary adjustments, which also reduces the need to zoom-in.
• Increase in focus can be selected easily DURING editing
• Enhancement of adjustability in handling of camera movement
• Straight forward storyboard function makes arranging clips and exporting into a single file
effortless
• Super fast full screen preview with new comparison modes, original/optimized, and Forensic
View makes evaluation of corrected video a snap
• Export in AVC/H264 mp4/mov und Apple ProRes
• Import von mov, mpg, mpeg, mp4, mts, m2t, m2ts, m2v, avi, mxf, vob, vcd, 3gp, jpg, tif"

Looking at their OWN samples also convinced me.

Grazie

When importing into mercalli, does it make sense to convert original h264 footage into cineform or similar "almost lossless" codec first, to avoid having Mercalli render h264 again into a new h264? Or do you think the difference would be negligible?

I will definitely try first and see if I notice anything, just wanted someone else's take on it. Thanks. M
