Red Rolling CMOS Shutter Redux, again.
One of the easiest ways to f— with video is to use flashes and strobes while shooting.
With CCDs, you’ll likely end up with one field of interlaced video completely blown out and the other “half” of the image is normally exposed. Apparently, with CMOS imagers, including the soon to be replaced first 100 RED cameras, strobes and flashes can look like this, where only part of the frame is illuminated. Odd, isn’t it.
The video on the Fini Films Site has lots of strobes popping, and most are captured properly, but a good portion- more than you would expect- aren’t.
