I was not able to get out to find a row of trees as a firmware update popped up and by that time the light was getting dim. Even so I tried Razor's suggestions (start with 2.7 and 4 in manual mode, try 24 fps at 50 shutter speed, then 30 fps at 60 shutter speed. I didn't have a row of trees for reference but I do have a very large oak tree off the end of the deck. So in the recording modes above and holding the Mavic I did a slow panning body rotation covering the tree. Of all the clips I took ONLY 2.7K at 30 fps and 1/60 Shutter exibited a smooth pan ... absolutely I saw jitterness in all other panning clips. What that tells me I really do not know .... why should only 2.K @ 30 fps x 1/60 Shutter speed be the only one?? Why not 4K @ 30 fps x 1/60 ?? I hope to make some more tests in the next few days if the sun cooperates.
