I mounted my GoPro Hero2 to the top of my 3DR frame using the standard mount and the resulting video was unusable- complete jello. So then I used tripod adapter with the camera and a 1/4-20 bolt to the top and still had unusable jello in the video.
Is anyone flying a hardmounted GoPro successfully on a 3DR frame? If so, how do you have it mounted and have you applied any tricks to create stable video.
Much thanks,
Pat

As Martyn said, try switching to 60fps, that will drastically reduce the rolling shutter effect right off the bat. If that brings it down low enough for you then you've saved yourself a lot of hassle with vibration isolation.
Check out the videos I have posted. I can send you some pics of my mounting set-up.

What GoPro are you using? Original, HD or HD2? Do you have the lastest camera firmware?

Rolling Shutter and Jello is only the symptom of the problem.
The problem as Tomas pointed out is actually vibration. You can get anti vibration stand offs that fit on the arducopter stand offs from a mikrokopter shop, as its standard to have the camera gimbal and control board on the anti vibration mounts.
Secondly prop and motor balancing is so important in reducing vibration. And unbalanced motor or unbalanced props creates a lot of vibration in the frame.
On my Mikrokopter I found only leg vibrating in the hover, I then discovered that one motor didn't spin completely silent when I spun the prop by hand, the rest of the motors were dead silent. When I replaced the motor, the vibration went away. I now only get jello when my camera is zoomed in at between 10 to 20x zoom.
mount it on a piece of foam from a hard case or something like that, then use rubber bands to hold it down. Dont tape it or hard mount it, the tape will transfer vibes easily.
Also, try buying some moongel at your local music store on amazon, it is the same stuff as those old sticky hands you used to get from vending machines as a kid.
It eliminated vibes
