![]() The plug-in also offers a state-of-the-art frame stabilization. The new Mercalli V2 PRO is not limited to correcting only rolling shutter skew. The temporal displacement (seen in the photo, top) from the top to bottom of a frame can often be seen in vertically skewed elements during rapid panning or movement of the camera.
 Not Just Rolling Shutter Compensation In contrast the CMOS imager converts the analog stream to digital at the surface of the sensor itself, requiring a systematic scanning of pixels like a computer monitor. The analog stream from the CCD is then sent to the digital signal processor (DSP) where it is sampled and further processed in the digital realm. Traditional CCD sensors capture the entire frame at the same instant, much like a film frame is exposed in a cine camera. For long-suffering RED and DSLR shooters the rolling shutter effect can be very distracting, and for folks trying to exploit the Large Sensor Revolution on a professional level the new Mercalli V2 plug-in is indispensable. ProDAD’s Mercalli V2 plug-in, for all its capabilities, can’t do much about these particular failings but it sure can address perhaps the most annoying shortcoming facing DSLR and FlipCam shooters: rolling shutter, the dreaded jello-like skewed effect seen in vertical lines during fast pans and tracking shots. ![]() In the typical DSLR, FlipCam or other rudimentary video-capture device, the minimal sampling, crude video encoder and high compression ratios contribute to bountiful aliasing artifacts and a highly constrained dynamic range. One consequence of the current large-imager fixation is the increased demand for cheap CMOS-sensor type cameras with resolution to 5K (and beyond), which leave a great deal to be desired in terms of performance.
