The famous Smoothcam effect, a plug-in available with Final Cut Pro 6. Two examples (thanks to family !) and for each, three footages : :
1) Without any smoothcam,
2) With smoothcam in automatic,
3) With smoothcam in manual.

This shows that you need different settings for different slow motion speeds and that certain footage cannot be slowed down to 1/8th normal speed.
So that I didn't get any motion blur, I set the shutter speed to 1/500th.
The sample footage is made up of two shots.
1. Original footage (which was shot 1080i) - scaled down for Vimeo to 720p
2. Final Cut Pro 1/2 speed version: ['Speed...' from the Modify menu] This throws away one field for each frame and creates new frames by blending existing ones.
3. Compressor 1/2 speed frame blended version: Takes each field and deinterlaces to produce a frame.
4. Compressor 1/4 speed motion compensated version: Looks at each frame to see in which direction groups of pixels are moving - creates new frames based on these guesses.
5. Compressor 1/4 speed high quality motion compensated version: As before, but spending more time analysing the pixels in each frame.
6. Compressor 1/8 speed high quality motion compensated version: As before, but slower. This shows that 1/8th speed doesn't work with this kind of footage, but it does 'go wrong' in an interesting way.
In Final Cut Pro 6 you can use the SmoothCam effect to stabilise footage. It moves and rotates footage to get rid of camera bumps. As doing this moves the footage such that it no longer fills the screen, SmoothCam can also scale up the footage so that you don't see past the edges of the moved, rotated footage.
This shows a hand-held (not well colour-balanced) shot. Then three stabilised shots.
The first stabilised shot uses 'medium' settings (2.5 out of 5). The second uses 'full' settings (5 out of 5). The third shot takes the second and pans it to show more of the scaled up footage.
SmoothCam works best on progressive footage and for those mastering to 720p using a 1080 camera.
