The interview do not mention that. Have you got other sources ?
GH2 Gh3 full specs now posted
- Thread starter keylight
- Start date
The GH3 firmware is at version 0.4, which means we still have a long way to go before we can truly judge what this camera can do.
well "no comment" is about as clear as can be with something like this. If this was the GH2 and he was asked, does it have a Panasonic sensor? There would be no reason that he wouldn't have said, "yes". And other interviews from people at photokina and even personal-view members asked the same thing; they do not claim the sensor to be theirs. I'm pretty sure that only leaves ONE feasible option.

There would be a difference. 4:1:1 has likely fallen out of favor due to the fact that progressive scan footage has become more popular than interlaced. Back in the days of mini DV, virtually all footage was interlaced. If your footage is interlaced, you have limited bandwith to work with, and you're trying to use a 4-to-1 luma to chroma ratio to squeeze the image into that bandwith, then 4:1:1 kind of makes sense over 4:2:0. If you think that 4:1:1 is nasty, you could conclude that the interlaced version of 4:2:0 was an abomination crafted by Lord Cthulu himself solely for the purpose of driving color compositing artists mad. With progressive footage, 4:2:0 is much more sane.
What is past experience with how different a camera performs from it's first physical showing a trade show to the first units in people's hands?
...If you check out the BTS photos of Philip Bloom's "Genesis" GH3 film, you will notice that he is often wearing a dark-cloth over the camera and his head while shooting. ( like you would with an old style view-camera ) The reason for this is that he was working with an even earlier version of the GH3 firmware, where the monitor out wasn't working, so everything had to be focused/composed ONLY using the GH3 EVF and LCD screen! ( probably without a working focus-assist zoom-in either )

Yes. Clearly, it has to be Foveon.
Oh, wait, maybe you meant Dalsa?
Or, perhaps you were thinking of Toshiba?
Or Fairchild?
Or any of who knows how many companies that make sensors?
Man, I wish people would quit spouting made-up bullcrap as if it was FACTS. Panasonic did not confirm nor deny that it was a Panasonic sensor, but that in no way leads to there being only ONE feasible option!

Agreed wholeheartedly. 4:1:1 existed pretty much solely in NTSC DV land (and DVCPRO in PAL). 4:2:0 in interlaced is hideous, and 4:1:1 made a lot more sense in an interlaced video stream. With the transition to progressive, 4:2:0 has displaced 4:1:1.

I've done several previews and worked with several early prototypes, and many times they have told me not to review the imaging as the imaging wasn't done yet. They are showing the form factor, the way things work, previewing the features that will be in there, stuff like that, but they may not have finalized all the various aspects of the imaging software yet.
Well, right, I get that certain elements weren't implemented yet, but this is stuff that's planned. What I'm asking explicitly is: where has there been a camera that, after having footage or actual physical bodies shown to the public, has had any kind of significant change in sensor quality or features added to it before the first bodies shipped to consumers arrived? Is there any basis at all to say, "Hey, this might change before you actually get the camera in your hands." or has history actually been "this is 99.999% of what you're going to get when your first orders come in."
That I can understand, but with a camera supposedly out around end of November/December, I wouldn't call this an early prototype. And even in that circumstance, was there any major difference to the image that you saw on those prototypes vs what you saw in the end product?

The HVX200 definitely had substantial revisions to it between the first showing (June-July-ish, IIRC) to the time I got it to shoot the first "real" footage on it (late November/early December). The HMC150, when I was previewing it, had definite image considerations that they said "don't show footage". In fact, IIRC, the very first time the HVX was shown, it was enabled to shoot 60i only; couldn't even do 24p yet.
It happens all the time. However, if the camera is far enough along that they're commissioning an ASC member to shoot a film on it, you can be reasonably sure that the imaging portion is considered basically "done" before they'd do such a thing.

Hopefully answered above. I would think that they have the imaging basically done at this point, or they shouldn't have been turning it loose to shoot that Bruce Logan film.
And yes, substantial differences in imaging between the early prototypes and the final versions. There are many levels of prototype.

And what are the differences exactly?
I assumed it was so they could release photos of him working without actually showing the camera he was working with ahead of the official release.
RED Scarlet.
It wasn't just a mockup? An actual working unit that people were allowed to use?
