Video Camera Stabilization or Deshake

I’ve got a lot of video that was taken with my small digital camera. It takes great HD video but because it is small and it’s shape most of the video has quite a bit of shake. I’m want to try and smooth things out when I’m filming but I’d also like to fix a lot of the video that I have.

Challenge: How to fix video that has a lot of shake?

I made this camera stabilization system out of aluminum angle. It needs a ballast so I used a small container with batteries in it. That way, it’s free to carry the batteries. This is all fine and dandy but it will make the camera even harder to carry, harder to recruit people to take video and it wont fix my existing video.
