My first several flights were perfect - none of the "jello" issues I had with my P2 and I've seen several people have with their P3s. Thought I was just lucky... Then I loaded some footage and BOOM - Jello. Ripples at nearly every turn. Very frustrated I tried to trouble shoot and voila - I had changed my file type to mp4. Shouldn't matter, right? I changed it back to MOV and the problem disappeared. I never changed the framerate or resolution, I just changed the file type to mp4 a couple flights back. Just tested with .mov and it's perfect. So anyone having the problem - try that. No idea why this matters, but it was night and day for me.
