Lock & Load X a Viable Solution for Reducing Rolling Shutter Artifacts?
Rolling shutter, aka "jellocam," is one of the chief drawbacks to shooting with large CMOS sensors. Other than to avoid whip-pans or shaky camerawork, however, there's not much shooters can do about it in the acquisition stage; is there a good solution in post? CoreMelt is a software company that's just released a Final Cut plugin designed expressly to reduce rolling shutter artifacts.
When a CMOS sensor records an image, it scans the image from top to bottom, left to right. This scanning action results in a slight lag time between the recording of the top left of the image, to the bottom right of the image, resulting in images with horizontal skew and vertical distortion. This effect, when coupled with the motion of the camera, creates the infamous "wobbly" image effect attributed to CMOS cameras. Lock & Load X now includes specific shutter coefficient values for the new DSLR cameras like the Canon 7D / 5D Mark II and 550D, Sony HDCAM EX1 as well as consumer camcorders like the Legria / Vixia and helmet cams like the Contour HD.
From their demo video, I'm skeptical, but as there's a free trial, it's worth checking out. Anyone have other solutions to reduce rolling shutter artifacts?
