Jello Effect

Canon have announced that they’ve developed a new CMOS sensor with a global shutter and expanded dynamic range. While a wider dynamic range is always good for every camera use, the global shutter is huge for video shooters. Finally, we’ll be able to completely eliminate “jello wobble“, skew and other rolling shutter artifacts in DSLR video.

The fundamental difference between a traditional rolling shutter CMOS sensor and this new global shutter is the way it records the scene. Rolling shutter sensors capture a line one line at a time, sequentially. This means that, now matter how small, the beginning and end of your exposure happen at different points in time. A global shutter records what every single pixel sees at the exact same time.
