That must be Nikon D90 video, 'cuz jam don't shake like that

I was certainly impressed by the D90′s videos a few weeks ago, but it seems that the rolling shutter issues created by the way data is pulled from the sensor make much of the video completely ridiculous — as some have noticed. Jelly motion!

RED ONE’s (the forums for which had this video) sensor had a similar issue, though not as severe, and they’ve since addressed it. In fact, their high speed CMOS sensor is purportedly miles beyond the competition and this is (I’d hazard) what is making them rock the DSMC and possibly the changes to the EPIC and Scarlet. Canon’s 5D mkII is reported to have some skew but not nearly as much.
