RollingShutter Reminds Us That While Jello Wiggles, Videos Should NotS

What's wrong with that video from last night? Things seems a bit skewed, distorted, and wiggly-jiggly. No, I'm not focused on that redhead in the tiny pink shirt, I'm talking about a fixable issue with CMOS-based video cameras.

RollingShutter, a plug-in for After Effects and Nuke, recently came to our attention, not because it's a good plug-in (although it is), but because it brings up a flaw with CMOS sensors: Video cameras using CMOS sensors tend to suffer from a major annoyance in the form of skewing anytime the camera is shifted or a fast-moving object flies through the frame. This is mainly due to the line-by-line top-to-bottom scanning done by these cameras and it will make your videos look like a mild acid trip.

The good news is that this pesky issue can be corrected post-production with tools such as RollingShutter. What RollingShutter does is use Local Motion Technology to correct that unsightly jiggling. This means that rather than globally correcting entire frames, the plug-in corrects individual parts of the images and prevents accidental introduction of new distortion.

Your camera won't learn to focus on the fly all of the sudden, but the difference in the before and after clips in the video is pretty huge and almost makes RollingShutters $500 price tag an easier pill to swallow for those who only want their jello to wiggle and jiggle. [The Foundry via badrobot]
