Rolling shutter definitely plays havoc= and introduces noise into the track a bit, but if you're able to simulate t= he same warble look, it may actually work. Might require a few extra hand ke= y frames on the position property to fine tune any pops in the track from th= e the rolling shutter noise. Good start though.

The wobble is much more apparent if you continue looking at it but at fir= st glance, it is still some compelling footage.  I did however pull a t= rack that is pretty tight.  Of course the wobble may be even more notic= eable.  I made no attempt to make my object wobble, however it is locke= d down pretty good.

I used the AE tracker as is, no warp adjustment or anyth= ing and got fantastic track points.  Then I just tossed in an building f= rom Element 3D, added a little Bezier to bend the building some.

These= two examples show exactly the horrible rolling shutter wobble that David me= ntion. You will have a horrible time stabilizing and tracking some of these,= and the extreme distortion of the GoPro optic makes it a even more un-fun.<= /div>

AE has a Rolling Shutter Repair effect, but i don't thin= k it can compensate for these cases, only the usual pan shear distortion. Or= ? i havnt tried it myself on any of such footage actually, so i would love t= o be proven wrong about this.
