HM100 at 1080i

Amos, I found my HM100 it is a bit noisy at the standard 0 detail setting. By reducing the detail to around -7 -8, it is very nice.

Tim mentioned this in is DVD

Andy, was this noise at 1080P? Did you have any gain on it? Thanks!

It was at 0db and 6db and 12db. I found it in all shots, even during the day. Please realize I am comparing frame by frame, not in real time.

I now shoot all my stuff, both 720 and 1080i at around -7 -8 detail. You loose very little perceived sharpness, but the image is much smoother and cleaner to me.

It is easy to see the differnce if you hook up the camera to a large HDTV via the HDMI port. Then adjust the detail while watching the TV.

Andy, I have HD110 and I generally shoot at -4 Detail to -6 Detail anyway just to avoid the "twitter" I owuld often get from the electronic sharpening around repeated man made objects.. (fences, brick walls etc). Probably most of the JVC's ProHD line might be better off having Detail -4 to -7 for a variety of reasons anyway. Just throwing it out there.

Yes, "twitter" is a good way to describe the sharpening artifacts.

In additon, on 1080i by reducing detail it seems to reduce "grain like" noise.
