My bets are they have the wrong Matte Box from Chroizeil. The CCD alignment “issue” is pretty much a non issue as folks have been using the Red Rock and underwater housings for the last two 1/2 years. Now if for some reason the CCD is really out of wack and I have seen cameras that have taken a thwump from a fall but not so bad that there is body damage it can be realigned. But this should also cause focus issues. This can be resolved with a stop to one of the Panasonic service ceters, either LA or Secaucus.

Hi,
The camera does not upsample anything. The part that is pretty frustrating for me is that people say stuff like this and they sound as if they know what they are talking about and then say they are not in favor of it.
Spatial Offset has been a technology that has been used by Panasonic and others for years, although I think the HVX is the first to use it in the horizontal and vertical domains. The technology has allowed chip cameras to exceed any sort of resolution you could get off of a tube camera because it is able to make resolution in the areas of the CCD where there is no photosensitivity, the registers. By offsetting the red and the blue sensors in both the horizontal and vertical domain you can capture resolution that otherwise would not be captured.
After this is added to the signal you are looking at an effective 1.1 million pixel imager. At this point it is captured in the 1080P domain where all of the camera processing is made and then when it is time for the recoding from it changes to that.
Keep that idea and then address the recording algorithm which is intra-frame, each frame stands on its own. Long GOP is not frame independent resolution and when you have a lot of motion and a lot of detail the long GOPs will throw the res away until the camera comes to a rest, where then everything will snap back.
1080 X 1920 is only good if you have an algorithm that can really handle it and so far the only one I have seen is the AVC-Intra or some uncompressed domain recordings. Keep in mind that AVC-Intra is 10 bit and the load on HD is 1.2Gbs in the uncompressed domain so with the compression that brings it to 100Mbs. Quite the feat and it still looks gorgeous, regardless of motion or details.
Lastly the HVX200A and the HPX170 share the same imager.

Sounds like the CCD was possibly jarred when it fell. It can be realigned, but that isn’t going to help your footage much.

Before you assume anything, why don’t you call Panasonic and ask them about it. That post that you pointed to is TWO years old almost, we were just discovering the problem and frankly I have not heard of a customer that was going to be billed except the gray market camera. I would think as long as your camera is in the country of origin you will find Panasonic to be very helpful.
The fix seems to be a permanent fix as the plate is more reinforced.

As Shane pointed out the 200A is more low light senitive, and this is due to the pixels being larger than the ones on the HVX200.
The pixel count is correct and with the saption offset it is close to the effect of a 1.1 million pixel imager. Since CCDs are analog devices and there isn’t a pixel to pixel relationship to the recording it seems to me that that more important count would be the physical size of the recorded footprint in DVCPRO HD. Most editing software will give you that when you do the setup.
Hope that helps,
Jan

Hi Tom,
I do not believe that I said anywhere in my post that the product would not perform as well. I only said that in the US, the warranty work will be free only for Authorized product here in the US. The warranty on the HVX200 is one year parts and labor, 2 years on the CCD, this is a very good warranty. And this is the warranty on all of the product regardless of origin, it just happens to be in the country of origin.
As far as the dealers of grey product, I have made the purchase calls myself and have had them ask if I wanted a lens included. I have had the tell me that they were going to charge me $300 for shipping from Brookly to NJ and then try to explain that with saying it was the insurance that was going to cost that much. I have had them tell me that the camera they sell at that really low price is out of stoch and because they are made in China they won’t have any more for a month or so, but they have a slightly higher priced one readily available.
Yes it is a buyer beware, and yes we may have some dealers that are less helpful than others that are authorized, if you have a problem with the product, they have the ability and in my survey, they always do help you resolve it.
Best,
Jan

So from your interpretation, Progressive Segmented Frame recording is not 1080P? Then make sure you tell all of the producers in the world that the CineAlter F900 is not 1080P. Okay? That does the very same trick of recording half of the fram on one field and the other half on the next field. But of course it is progressive, and for the rocord, the even our DVX100 does progressive in the very same way.
I would say that most certainly the Sony CMOS image does start with mor pixels, but it is the nature of the rolling shutter and the Long GOP that may get in the way of all of that beautiful resolution. Of cours if you are shooting slow moving objects or interviews they will look consistantly stellar, a little too video-ish for my tastes but it will look very clean and sharp. But move the camera so that there are lots of changes, tall buildings during a pan, uncontrollable flashes of light.
See resolution isn’t everything it is the pictures that are and if those pictures are consistant, it is much easier to sell. Pictures that lose too much during a pan and snap back when the camera stops are weird to look at. Pictures that have tilting buildings and two exposures durin the same frame are weird. CCDs do not have these issues. CMOS does.
I actually have a shot where the camera is not moving but the babbling brook running through it is. The HVX200 shot, and I am not talking the 200A, is sharper and has more resolution. But this is due to the Long GOP 35Mbs codec. Do not discount too quickly the power of an I-Frame codec at 100Mbs. And do not for get that DVCPRO HD is a 4:2:2 color space.
Oh and the 200A has about the same lowlight capability as the EX1, so then it is a matter of resolution differences and as I have pointed it is the pictures that you make that sell your work. If your work is inconsistant because the imager is inconsistant, how do you expect your customers to feel about your work.

Actually you really can’t trust the vendors that are offering at such great deals. Why, because there are no such great deals. I tried to order one at $2595, and was asked if I wanted a lens with the camera. I said, but it comes with a lens and they said that the lesns was extra. I tried to buy one at $4695 and they wanted to charge me $500 insurance on the shipping which was also overpriced. I was told by one of these vendors that the unit that was cheap they were out of stock on, and I would have to wait 2 months to get it, or I could have one of the more expensive ones that they had right now.
This is just a taste of what gray market camera purchasing is like and here is what you get if you do end up with a camera at a cheaper price, no US warranty, no P2 Card and no Barry Green Book. These are all items that come with the US model. The warranty for any camera is in the country that it was originally shipped to from the factory.
Lastly, not sure how many HVX200s are left out there, and only the US models are valid for the $400 rebate in the US. The HVX200A has better lowlight, better signal to noise and better clamping on the smear that happens when you hit a bright light source.
Hope this helps,

The HVX200 as well as the A has 24P and 30P in 1080. It makes a segmented progressive frame,like HDCAM, and lays it over two fields.
The noise on the HVX200A is much quieter. You should take a look.

Hi,
The P2 Store is a USB2 device and I know that in some cases the MAC sets it up as a USB1 and in that case it would be very slow. For the full P2 Store I would expect it to take about an hour and 15 for transfer. For the HVX transfer over firewire, my experience is about 1 GB per minute. The Duel-Adapter is about 2 GBs per minute.
Hope this helps,
Jan
