More HVX200 info

I see a lot of language difficulties here. I hope Jan can get her Panasonic people do put together some really cool diagrams to explain this to people – if not, Jan, give me a shout and I’ll draw up some pictures based on your information to help clarify this for people.
As I’ve said on other forums, it really sounds like Panasonic are taking an sensible engineering approach, and I think Toke agrees, but is having bother figuring out exactly what Jan is getting at.

‘I see a lot of language difficulties here.’
Graeme, I see it as more of a engineering difficulty. If we were discussing the vaccine for Bird Flu – openess would be morally the correct thing to do. But we’re not. Panasonic, or any other camera manufacturer, is under no moral obligation to tell us all the factors discovered through their research to explain a design decision. What we think is rational, is not; because we don’t know all those factors of how a reflected photon is manipulated to get the best possible picture at a reasonable amount of money. Those factors are secrets and not known company wide – in any company manufacturing anything. Quests for information will sooner or later hit a brick wall. Granted, brick walls are a frustrating obstacle.

Well, obviously Jan is holding back proprietary info, but on the whole we’re talking about common enough and understodd principles, and I do see a lot of language problems. I think Jan has been super good to respond in the way that she’s done when it’s obviously a frustrating discussion and I think we’re all looking forwards to seeing the blog entry on this.

[Randall3] “You keep implying that Panasonic has intentionally engineered an inferior camera when market share is so obviously at stake.”
Can you tell me, how do I do this?
I have already said twice, that using h&v pixel shift is the best thing you can do with this camera.
(And with every camera with small chips & YCbCr recording.)
At first I was worried that hvx200 would use only horiz shifting, but Jan informed us (at least for me this was news) that it will use both h&v.
Pixel shifting is a trade off between ultra sharp color resolution and camera’s low light sensitivity.
I prefer the latter one. It gives the camera much more flexibility and after all what’s the idea of $6k camera if you need 6kW to light a simple small things…What I would have liked to do is to have a conversation about what pixel shifting is in ideological level and how it’s done in practice. I believe that deeper understanding of a technical tool, will always benefical when this tool is used for creative work. Then we would have to have define a couple of terms more precisely to be able to use them.
Obviously this was an bad idea and others here do not want that kind of conversation here.
I’ll give it a rest. -

I know – knowledge is a virtuous pursuit. I apologise if I seemed short with you. But what, or more importantly, why things are done in practice is going to run anyone into that frustrating brick wall I spoke of earlier. For example, Steve Mullens, who does a lot of technical reviews on the web, was told by Canon that they would NOT tell him how their new H1 camera obtains their 24f (faus 24p). Brick wall.
Your imput AFTER the HVX-200 is released will either help to explain the marvel of why it works so well, or to explain its shortcomings as you see them. In the end, the picture will be the story, yes?

Definitely yes.
