Heli Stabilization comparison
Recorded with a cheap DealExtreme keychain camera, stabilized with Warp Stabilizer in Adobe After Effects CS5.5.
The helicopter is an E-Flite Blade CX2.
The keychain camera drops a lot of frames, and its lens is attached via a threaded disc that vibrates in and out as the helicopter flies. Focus is good for the main part of the flight, then very bad right at the end.
