Hello,

I've had my GL2 for about a year and a half and recently I have been noticing that the picture seems to be "pixilated" and the quality just doesn't seem to be what it was. Is this just the lighting that was being used or could it be some sort of other problem? Thanks for the help.

We need more information:

1. what kind of subject did you shoot

2. with what settings (mode, shutter, iris, other settings etc.)

3. what did you view this footage on and how

4. if the footage was captured, how?

I was just showing one of my friends how to use the camera so I was on full auto mode at the time. I had the camera linked to my TV with an S-Video cable and were using that as a monitor, so we wern't actually capturing the image on tape.

Can you reproduce this? Normally such problems are some sign
of problems with the tape or tape transport. But since you weren't
playing back from tape (right?) or capturing this is weird. If you
can reproduce it and it is not related to a tape issue it might be
time to send your camera in.

Well I just tried it again and I should clarify that when I say that it is pixilated I don't mean the entire picture. It seems to me when looking at it, and maybe it is just my TV, that around the edges of a persons face or even a speaker, that there is some distortion or pixilation. I'm not sure if I am describing it right it just looks "fuzzy" around the edges of things, they aren't sharp.

I also just tried it with manual settings of S 1/60, F 3.4 and 12 db and shot a wall that was painted white in normal indoor lighting and watching it on my TV and using it as a monitor it looks "noisy". I'm not really sure how to describe it, looks kind of like "snow" that you see on TV's but not that heavy, there is still color but you can see things moving in the image.

The 12dB of gain grain is what you're seeing. Light your scene a bit and keep that gain at 0dB. Now how does it look?

Yes, you're right it does look better, alot better around the edges of things. Thanks for the help!

Once again, I hate gain.
