Hi; I am in the process of researching the purchase of a GY-HM100U and as part of that research i downloaded some footage from the JVC Canada website. I love how the camera seems to handle colors and sharpness but any motion at all seems to be a blur. If you look at the front leg of the moose photo here you will see that during even a slow walk the leg is almost a total blur. I would assume that they would only use the best footage possible to sell their cameras so does anyone have an idea what the problem is?
You can't judge a camera's performance properly by footage downloaded from the web. It will be highly compressed and interframes introduced, this will particularly effect the way motion is played back.
I have a friend that uses this camera for corporate work. The results were so good one of his clients had a broadcast tvc made from material he shot.
I've been shooting for over a month with the camera, and haven't noticed any blurring or motion issues. Outside, you'll probably be above a 1/60th shutter because of 1 ND filter setting and everything will be sharp. Indoors, you can get by with a 1/30 shutter. I rate the camera at 100 ASA (pretty low). Depends on what you want to shoot with it.
there's plenty more out there. Philip Bloom does a nice review of the camera. I would stick to 720 30p or 60p, with detail set to OFF.
The zoom and controls leave a lot to be desired, but it has very good quality for shooting for the web. I did a two camera shoot with a HVX200, both at 9db gain, and I think the HM100 looks better - despite the better DVCPRO HD100 codec of the Panasonic.
I use 16gb Transcend class 6 cards with no problems, and PNY class 10. The Transcend cards are $26 at B&H! That's cheaper then Betacam Tapes back in the '90's (1 hr @ card = 2 tapes @ $30). At that price you could keep shot footage on the cards and not re-use them.
Better to use 1 hour or less (16gb) cards for ease and speed of downloading and cataloging footage - but that's a workflow issue.
