For the common shaky video clip using video stabilization will impressively make the annoying camera movement disappear. iMovie does this stabilization in two steps. First it will analyze the video clip frame by frame and pixel by pixel, comparing one side of the frame to the other. Once it has analyzed the clip it applies a function that scales, rotates and moves the video based on the comparison. It zooms and trims the clip as much as it needs to apply the reverse movement of the camera shake and still not go outside the video frame. What's more interesting is this video stabilization is the same effect Apple uses in their professional visual effects program Shake.
