HD TV Camcorder?

[ypauls]

Dear Video Expert
Though I have been a Sony DV camcorder user for over a year, and happy
with the results on my 27" regular tube TV, what camera is needed to
produce satisfactory results on a 40" plasma HD TV?
Is there one?

The only one you'd be interested in taking on vacation with you is the
JVC-GRHD1. I think there is still some debate as to weather it's true HD
though from what I understand. You might be happier with a 3 chip DV
camcorder like a Sony TRV-950 or VX-2100 or some thing like that.

Both the sony cameras make widescreen by cropping the widescreen
image, that mean on a 16x9 HD screen that the image would be blown up
by 250%. That would look much worse than a 1 chip MPEG2 image from the
JVC, which would have the same format (but higher bitrate) and
resolution as HD broadcast footage

The Sony's provide a true anamorphic option, not a mere crop. The do it
by cropping the bottom and top 12.5% of the image and then stretching
the rest into 16x9 ratio. Therefore the loss in resolution compared to
the 4x3 image is 25%, down to 405 lines from 540. Doesn't seem that long
ago we used to crow about how wonderful 400 lines were!

This would be more of a concern, if the scaling was done from a 720 x 486
(NTSC) chip, but many cameras have chips of much higher resolution, so this
is not nearly the problem that it once was. I have not studied the VX-2100,
but
as near as I can tell, the 950 uses a 944 X 528 section of the array for 16
X 9,
and 944 X 708 for 4 X 3. The array used for Still mode is 1152 X 864. So,
even though a larger section of the array is used for 4 x 3, the array used
for
16 X 9 is still larger than the resolution of the image output. The PDX-10
seems
to use the same chips, but uses an even larger array for 16 X 9. I did a
little web
page to help explain what I think I was able to learn about this at
http://www.techshop.net/PDX-10/

I don't know how big the arrays are for the VX-2100 or PDX-170.
