EX3 rolling shutter?
on May 8, 2010 at 2:20:30 pm

Was shooting a client's EX3 yesterday, and one scene called for an over the shoulder of an actor watching a TV...it just happened to be an old CRT TV. I was surprised by the picture on the TV rolling. As we were shooting 24p, I tried adjusting the shutter, clear scan and whatever else I could think of. No joy. Finally decided it was a CMOS issue and told the director he would need to fix it in post by replacing the picture. Did a lock down and moved on.

24 hours later, now I'm wondering if I could have switched the camera to interlace and pulled it off, or would the result have been the same?

Any thoughts?

Yes, it could have been corrected. Such are the hazards of shooting with an unfamiliar camera.

Thanks, that was so...insightful. Care to offer some wisdom about the fix?

I set up a shot similar to yours--CRT television, camera shooting 24p at 1/60 no problem. Tried again adjusting the ESC, again no problem.

And no, it's not a CMOS issue.

There. Did that help?
