Grainy/Noisy DVX footage. Why?
on Feb 4, 2010 at 8:53:52 pm

I am pulling my hair out on this one. I recently finished a shoot with my DVX 100A and the footage came back looking like I had the gain set to +18db. Grainy and noisy. When I played the tape back in the camera it read 0db so I know the gain was off. I shot at 24p, Cinelike V, 48fps.

In the vectorscope the luminance is spot on so not really underexposed. Also, when it is viewed on a broadcast monitor the noise goes away. Arrrgh, so frustrating.

Here is a link to some footage

Wait I don't get it- you only see grain on the onboard monitor and not anywhere else? Then recalibrate the monitor.

Hey Noah,

I actually never saw the grain in the on board. What I meant to say is that when I played the tape back in the DVX the readout in the screen reports the db level and iris level at the time of recording. When I first looked at the captured footage I immediately thought, Dang, I mus have bumped the gain switch to high. When I played the tape back in the camera, tho, it just said 0db.

The footage looks like crap when played back in QT. But when I watch footage output to an NTSC monitor the blur and noise disappears.

Well then don't worry about it- if it looks fine on an NTSC monitor that's your final output.
