Rolling Color Shift Waves on EX1
on Apr 9, 2009 at 2:47:11 am

Two clips out of dozens I shot in a photo studio under hot tungsten lights (no florescents) at about f5.6 had subtle rolling waves of blue color moving horizontally up the screen for several seconds which made the clips unusable. I thought it may be a transfer problem, but it shows up on the SxS cards. I shot everything 1080p30. Anyone have a similar problem or know what the cause is?

EX1 (without the firmware update)
Mac Pro
FCP 6.0.5

Thanks!

Hi David-

It sounds like interference from something like a Nextel or Blackberry, or some other kind of rouge freqency; esp. if it's just showing up for a few seconds on a couple of clips. I've had similar issues like this with other devices interfering with the video signial.

But, it could be something else, too. Could you post the clip?
