i am curious as to how severe the bending of the image is, particularly on sudden motions like a turning head -- where the shutter speed is somewhere around 1/60 or 1/48 of a second.

i have looked around online and found nothing. it baffles me how these chip-camera sellers neglect to post more than one or two examples of the camera's output, if even that.

My gut tells me that this will only be an issue in shots that would normally be result in motion blur (fast movement at slow shutter speeds) or strobbing (fast movement at high shutter speeds).

I expect rolling shutter artifacts to be invisible in shots designed to avoid strobbing and motion blur, which is the proper way to shoot progressive video anyway, but I'm yet to confirm that hunch.

I also expect rolling shutter artifacts to be invisible on videos shot with interlaced CMOS cameras when they are viewed on CRT monitors because CRT monitors display images the same way CMOS cameras capture them.

here is a good example:
