Mr. Kazuo Okamura's test shoot for Mac & Win

According to the brochure there is no mention that the CCDs are 16:9.

Given the level of secrecy my best guess is the CCDs are the very same ones used in the DVX100AB's, pixel shifted to provide additional 'interlaced resolution' with the attendent problems of low contrast, luma nioise, chroma noise and hue shift.

Whether that's good or bad is in the eyes of the beholder.

In the prosumer market, hype and first look image impression is a big factor in sales.
'Pay no attention to the man behind the curtain.."

I am getting the feeling that this new crop of prosumer HD cams have no more
image resolving ability than my antique JVC HD10.
There, I said it.
This doesn't mean that you can't make a nice film with them! The lack of settings made that very hard on the old JVC. But I'm still curious about the actual resolving power, after the candy coating ( edge sharpening ) is peeled away.

This is important to anyone who actually thinks in terms of the overused term 'film look'. Ringing on sharp edges is a dead give away to the video look. Sure, film that goes into a DI process often gets sharpened, but that never causes ringing ( overshoot on edges that look like black lines ).

Let's see some charts.

On the Panasonic Web site, HVX200 product description, sixth bullet down states:

"1/3" 16:9 native high-sensitivity progressive 3-CCD with 1080/60p scanning"

Then on the FAQ page:

"What size is the 3-CCD imager?
The imagers are 1/3" CCD, 16:9 native aspect ratio..."

And finally, on page 12 of the brochure:

"16:9 Squeeze and Letterbox Modes
The AG-HVX200 can record in SD with a 16:9 or 4:3 aspect ratio.
When 16:9 is selected, the AG-HVX200 can record in native 16:9
recording..."

Seems pretty clear to me.

that is right.

Kaz Okamura posted new clips that I requested for the DOF test :

80mm?35mm?÷ 7.2 = 11.1mm
100mm?35mm?÷ 7.2 =13.8mm
The result is very good and I'm pretty much satisfied about it.
The other one is a gain test, I see the noise when it +12db that I never use anyway.

Thanks Kaz again.

I will make new thread.
