If a person is complaining about a grainy image and does not state how he is monitoring it, we really can not help much.

The only way to judge is to connect the camera to HDTV and play the original tape. If he is using editing system with normal PC monitors and small images, anything can be going on totally unrelated to tha camera.

So, what was the monitor and how did the image get there?

Looks like our original poster, Eddie, fell off the face of the earth...or maybe realized he was shooting in "green box" mode. ;)

I shoot most indoor events at 6db at 60i. If the venue is really dark, I'll do all shooting at 24f so I can gather as much light as possible. Compared to -3db there is grain, but that's only because -3 is so clean. I have not (yet) found a preset that masks grain from the 12db to my liking.

I am with you. 12db and up seems impossible to mask.

There are plenty of presets and some are noisier, other cleaner.
IMO the cleanest presets are:
VIVIGRGB
PANALOOK
VISION02

Where does my XH A1 noise come from?
 
Sorry for not getting back sooner.

With AGC OFF and gain set to zero I get grain on my XH A1 where the light is dim. I am uploading to my PC by converting to a Cineform intermediate in HDLink at high quality and watching the footage in Windows Media Player on a Samsung TFT monitor with enough resolution to display high definition footage. Any one know where the noise might originate?

My camera settings are:

NAME : FACTORY
GAMMA: NORMAL
KNEE: MIDDLE
BLACK: MIDDLE
MASTER PED.: 0
SETUP LEVEL: 0
SHARPNESS: 0
H DTL FREQ : MIDDLE
DTL HV BAL : 0
CORING: 0
NR: OFF
NR2: OFF
COLOR MAT. NORMAL
COLOR GAIN 0
COLOR PHASE 0
R GAIN 0
G GAIN 0
B GAIN 0
RG MATRIX 0
RB MATRIX 0
GR MATRIX 0
GB MATRIX 0
BR MATRIX 0
BG MATRIX 0


Is it possibly because I have the pedestal set to zero on the camera?

I'm hoping when I edit I can correct for the noise.

Thanks.
