Since I was searching for some info on this recently, I thought I'd post some experience with worse case scenario aerial footage. The scenario was that a client called me at the last minute to shoot some aerial footage from a piston helicopter. The pilot was ready to go within the hour but we had no gyro stabilization and I had no experience shooting aerial video. After giving fair warning that the footage may not be usable due to camera shake and getting a "do the best you can" response from the firm, this was the original footage shot with the V1u in 1080i60 at 1/125 shutter, variable iris & manual focused, completely handheld. The raw footage is here:

Next I transcoded the original capture to ProRes in Compressor, re-inported and ran the smoothcam filter on the footage. Since the smoothcam filter anaylizes entire master clips, regardless of the edit timeline, this was an overnight process. Recommend making master clips as short as possible.
Results of the smoothcam are here:
Port Authority Aerials - w/Smoothcam on Vimeo (http://www.vimeo.com/2357322) with a slight gamma level adjustment for those of you on PCs.
While far from perfect, I was pleasantly surprised at what a difference the Smoothcam filter made.
Observations: -Needed to shoot with the viewfinder as screen added to wind resistance and increased buffeting. -Needed to keep lens inside open door for same reason. Avoid temptation to zoom for same reason. -Do not brace on airframe or knees to avoid shake transmitted from the airframe. -Smoothest when shooting with camera pointed from the 9 o-clock to 11 positions. -Get some type of gyro system for next shoot. -Build up muscles to allow better stability while holding camera to the eye for an hour and trying to maintain orientation while hanging out of the open door of a helo.
Final note: Though I was a little disappointed with this footage, the client was more than satisfied responding that some shake is expected by the viewer when shooting from a helo. And since I know that only a few seconds of the footage is likely to be used, I'm confident that with the Smoothcam filter, they will get the results they need.
Still new to the video world, from still shooting, and would be happy to hear any tips. Likewise, if I can help further with any lessons learned, let me know.
