iMovie Eleven and its telephoto settings

You may not know what it's called but you've definitely seen it. The wobble or "jelly" effect seen in video captured by cameras with CMOS sensors relying upon rolling shutters instead of the global shutters found in cameras with CCDs. The issue stems from the way a CMOS acquires the image by recording each frame in horizontal bands, working from the top to the bottom. Since all parts of the image are not recorded at the same time, moving the camera, even slightly at telephoto settings, causes the image to skew and go all rubbery. Well, iMovie 11 can fix that, or at least smooth it out with options for Low, Medium, High, and Extra High distortion reduction. It's just one of many new additions including the often discussed Movie Trailers, support for 24p footage, vastly improved audio editing, and a People Finder feature that lets you search for family members in raw footage... but it might be our favorite.
