The home web page for the Replay XD features this video for the camera and uses an RC heli for filming, you can see the shadow of the heli in the first scene as it yaws around and again later in the video chasing a car. http://vimeo.com/40502226 http://replayxd.com/
I'd like to see a side by side of a ReplayXD with my ContourHD camera. The guy in the video says it doesn't get any jello effect, but they didn't mount it in a helicopter...or was it? They did not say that the aerial view were from a ReplayXD, and if it was, how was it mounted. Did they mount them hard with just the solid fixed mounts or soft with some vibration material.
The above video has some Jello, if you look real close, but without all the details it would be hard to tell.
You can see the jello between 19 and 21 seconds in the video, and I don't know if they used the same camera on the helicopter that got ran over by the car, twice. It probably didn't do it much good.
I would have liked it if they showed the camera after it got ran over. Maybe they have a "making of" video somewhere with the behind the scenes info.
