For the last 2 months I have been shooting aerial footage using a GoPro HD Hero camera. Awesome camera. As part of the process I have been experimenting with how to best process the video to remove shaking from the video clips as the camera itself does not have an image stabilization function.

I just posted a side-by-side video comparison of two different methods of stabilizing video footage: Method 1 is using the built-in Stabilize Media option (Tools | Video menu) found in the Sony Vegas Studio HD Platinum 10.0 software. This is an earlier version of the proDAD Mercalli video stabilizer that has received good reviews. Method 2 is using the VirtualDub video editing program and the companion Deshaker filter plug-in, both of which are available for free.

I included embedded comments in the video and which method I like better. If and when I decide to shell out $200 for the proDAD Mercalli plug-in I will also post a comparison of that. For now, though, I'm happy with

Stabilization settings I used: (Note: I first convert all GoPro MP4 video files using the HuffYUV lossless codec in VirtualDub and saved as an AVI file before deshaking)
