RollingShutter Reminds Us That Videos Should Not Wiggle Like Jelly

What's wrong with that video from last night? Things seem 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.

Video cameras using CMOS sensors tend to suffer from a major annoyance in the form of skewing any time 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, a plug-in for After Effects and Nuke. 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.

The difference in the before and after clips in the video is pretty huge and almost makes RollingShutters $US500 price tag an easier pill to swallow for those who only want their jelly to wiggle and jiggle. [The Foundry via badrobot]
