HVX200 Has Only 960x540 Pix Chip?

I just talked to someone very knowledgeable about cameras. He said the HVX200 has only a 960x540 pix chip and that it is uprezed. He said that Canon took the camera apart and discovered this, and that it has been confirmed by other sources. He also said that the image falls apart when you attempt post special effects such as compositing due to the uprezing.

He went on to say that Panasonic is having problems with the codecs and that is why there is so much delay in getting the camera out. It may be that they are trying to do a workaround for the uprezed images coming apart when manipulated.

Does anyone have info on this? I have 2 of these cameras on order and I will cancel my order if this proves to be correct.
 
Neurodancer,

Do a search of the HVX Latest News forum for answers to this and many other questions you might have on the HVX. There are resolution tests, explanations on 4:2:2 colorspace, a debunking of how the camera achieves its remarkable images and so forth.

It's all been covered ad nauseum.

Cheers,

e

the camera is great - who cares the size of the chip

I care! When it comes to resolution, you can't get what is not there. I just searched around posts having to do with this subject. All I see is speculation as to what the pix count is. Panasonic site has no specs. Are people on this board deluding themselves? If Panasonic won't reveal this basic info, how could anyone of reasonable intelligence buy this unit? I don't care how good they interpolate the image; the information won't be there.

I am sorry if this rains on your parade. But let’s get real here. If Panasonic is selling this unit without giving specs, something is drastically wrong.

This is a good size investment. I am definitely putting my purchase on hold till I see some specs.
 
Panasonic HAS released the specs, it has been confirmed. Search the forum.

And if you read up on the forum you will also find the math as to why that's the perfect size for 4:2:2 HD rendition.

oy - ok here goes.

It doesnt matter if the end result is a resolution you want.

I assume if you researched then you understand pixel shift and how that CAN interpolate data correctly with an upper limit of 1.5 times the actual data. And you also know that the panny HVX pixel shifts in both x and y direction.

Or you can get the camera and test for you yourself. I have one, have performed a film out test and the 720P footage stood up to a blowup and looked beautiful.

Or conversely you can get hung up on a number.

Oh yeah - and you also could find out that panny has released the specs

I think you will find that the HVX is as good as if not better than the other sub-10k HD cameras out there resolution-wise. Barry Green posted some examples of Z1, HD100 and HVX resolution tests, and the HVX looked just as good if not better.
 
who cares?

chip size discussions were entertaining back before we started to see footage posted. now it's old. i saw hundreds of posts re chip size. a few of them nailed it but i honestly forget what the final verdict was because...who cares? we now have footage to review instead.

if you're going to troll, at least whine about something relevant like p2.
 
Personally, I'll take higher lattitude, 60p, more filmic noise, more filmic color, better highlight handling, 4:2:2 color space, 100mbps intraframe compression, a established HD format, and tapeless workflow over 800 lines of resolution any day. But maybe that's just me. ;D
 
Seriously Neurodancer, you only need to connect the camera to a HD monitor and switch from SD mode to the HD modes to see how exactly how high-definition it is.

Really, do a search for the love of Mike.

Thanks for the link. I still come away with "Spatial Offset formula" as jargon for interpolation. What is significant is that there are not many cost effective alternatives to the HVX. What I may do is just buy 1 of them and wait for the next round of cameras.

I am going to have a look at the new Sony PDW-F350 1/2" chip camera at NAB. Anyone need a ride from the S.F. Bay Area? Leaving Sunday 23, come back Wed 26.

Hi there, if you are worried about chip sizes , resolution etc go to www.coax.tv and read
Thore Nordahls reports. More precise information you will probably not find. He compares the figures and gives - at least in my opinion - a fair assesment .
i am going to rent the camera next week for two days, compare it to a Sony Z1 in the exact same environment and the trust my eyes , my Tektronixs, FCP etc , sleep over the whole thing a couple nights and then I will decide. I know this is a very simple and humble advice, but sometimes it is just as simple as that.
 
All the sub 10k cameras uprez or pixelshift or interpolate to some degree except for the JVC which has 1280 x 720 chips, sort of, by splicing two chips together which creates the dreaded SSE, Split Screen Effect.

To me the footage produced by the HVX is the most colorful and filmlike.

Also with HDV the mpeg kills it and it doesn't handle motion well.
 
cameras arent just resolution, its also the optics.. which seems to rock on the hvx, (leica), and many other things, personally i found the image of the hvx mindblowing, others claim to have blown up the footage to 35mm for cinema screening and still the quality amazes them.. shoudnlt that say enough? for the price, i think the image is amazing, not to mention the versatility of framerate and shutterspeed changes. I'm just ticked off at waiting so long for the pal version... panasonic i want my camera!!! ahhhh!!!!

Well, it's not. So either research it properly yourself or live on in ignorance. Your choice. :0

BTW, for canon cameras like the XL1, they called it "pixel shift." Search that too.

I did not notice a motor that shifted the chip back forth to make the pixel shift work, LOL.
