Here is the reason why I changed back. This Fence test is a good example. best seen in full frame monitor
HC-VXF1
HC-X1500
as you can see now the difference and why I changed back. I can pan faster with the 1500 without any jitters the VXF1 would at that speed be unusuable

To be honest I couldn’t see the difference, I put them both full screen, I thought the first one had better colour and was sharper. The framing and light were different so it was hard to tell
just a question of getting the settings correct Bruce
Did you use a 27inch monitor in 4K or bigger viewing in full screen? The jittering shows up well
As a rather late post I think this jittering is a fault in your computer set up because I watched both videos on my 55" 4K TV and apart from the differences I noted above I can’t see any difference.
Perhaps you should avoid videos of fences? 
There is always the rolling shutter effect but an object has to be moving pretty fast to bring that up (eg windscreen wipers close up)
my monitor is the problem I think. it is factory set @ 60Htz . I could lower it but happy with the way it is. therefore my cameras/camcorder I now have matched to this
