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.
