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.
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.
