Using AE to link your clip and use rolling shutter removal and warp stabilizer can help but only so much and you probably won't like the results.
The only way to get jello-free video is to not have it in the footage to begin with unfortunately.
The P2+GP+gimbal combo can provide jello free footage but it take effort AND luck frankly.
The effort part involves prop balancing, using an ND filter to slow shutter speed and anything else that can remove or dampen vibration in flight. Using a higher fps recording rate (ie 50 or 60 fps) can also help.
But even the best effort will sometimes produce video with jello or micro-vibrations visible especially on large viewing screens (ie 65-inch TV).
There is hope that the Inspire 1 may produce jello/micro vib-free footage more often than not but the jury is still out.
Hope that helps.
