Are we sure it’s 1080/24p
I see conflicting statements. Is this camera truly 1080/24p?
And how much storage space per minute is this stuff going to eat up at that rate?Thanks

It says it is here, also in the downloadable pdf

Define “truly”.
Camera seems to be still in design stage (different mock-ups here and there),
so that’s propably the reason we are not getting full specs eg about ccd’s.Could you call camera with 1280×720 ccd’s (I hope they are not having more
resolution for the sensivity issues) “truly 1080”?
With pixel shift I might… -
That’s exactly what they’re doing on their bigger 1080i camera. They really want to get a sweet spot between dynamic range, high resolution and low noise / low light performance. That’s because a pro level camera is useless without all three. I think Panasonic understand the difference between high definition and high resolution.

Yep,
actually if z1/fx1 has 960×1080 and it’s sensivity is horroble,
it might even be better if hvx would settle 960×720.
With both horz&vert pix shift there would be enough resolution
for decent 1080p. -
It’s definition at 960×1080 isn’t up to much either. I’ve got a feeling that the chips will be 1280×720, but that’s just my feeling. It sounds that Panasonic are working on something special as they’re very keen for people to get a good dynamic range out of the camera too, and that’s not something companies optimise for at such a price point, so it will be very interesting to see what they come up with.

I’m hoping for 1,280 x 1,080 so that there’s no pixel shifting. You can’t assume that all CCDs with denser pixel counts are equally plagued by low dynamic range and light sensitivity. I have to believe that Panasonic can develop a 1,280 x 1,080 CCD that solves these issues.

Ccd sensivity developes slowly as material science and research develops,
but I don’t see any reason why Panny would have somekind of surprising
miracle in their backpocket in case of sensivity.
AFAIK they don’t manufacture ccd’s by themself. Am I right?
If so, Panny just have to follow the overall development.So if there is any reason to believe that hvx-200 will have exceptionally
better sensivity (which has a straight relation to pixel area size) than
other products around, just let me know.I think we need at least 2 stops more than fx1/z1 which has 960×1080 cells.
Ccd sensivity usually gets better something like 1/4 stop per year.
If hvx will have 1280×720 it will be only 1/8+1/4 (pix size + 1 year development)
stops better. Better ad-converters and signal prosessing can help a bit, but so
far it looks like only half a stop more sensivity when 2 stops would be needed.960×720 would give half a stop compared to 960×1080.
Jvc hd100 has 1280×720 if I remember correctly.
Any reports on its sesivity yet? -
Again, all other things being equal, yes, increasing density decreases sensitivity. But signal processing logic differs, pixel array design (photodetector type and the positioning
of the photodetector within the pixel) and manufacture (material used) differ, and light-sensitivity variability within a pixel array differs between two different CCDs that otherwise have the same size and pixel count. So is there any reason to believe that Panasonic will have something markedly better than Sony or JVC? I don’t know, as I’m not privy to their R & D. But pixel shifting, while it permits higher resolution with a smaller actual pixel count, does so at the expense of chroma information. It doesn’t make much sense to me to advertise 4:2:2 sampling when a lot of that is eaten up through pixel shifting.
