Frage von Lutz Dieckmann:
Hello,
I have finally managed the first footage of the new files, JVC GY-HM700 upload. More in my blog (see signature). Server server is not the fastest but nothing ;-)
Please forgive me while filming Wobbler (tripod and a strong zoom) and I think once I have the sharpness is somewhat misplaced, in the absence of a.
And always tuned think it was a handgebauter prototype.
Many greetings
Lutz

I'm just so fussy, or if the lens actually over the entire focal, even in the central area, a significant Chromatic aberration?

Deti Hi,
So much more than you can argue, I see them s.manchen places but not everywhere. At least I feel they are not considered so disturbing.
As I said, You wanted footage of a prototype! The finished product will these pictures certainly far surpass them. I know there is at least no different.

Especially in the VIDEO TREFFPUNKT posted:
"Each of us knows the famous experiment in physics teaching, where a narrow beam of light in a prism of which was then on the projection screen in the rainbow colors split.
And just so that CA has something to do. The long red light is less strong "derived" as the short-wave blue, but much of the re-used glass places depends.
In the optics used, therefore, at least so called. Flint Glass (http://de.wikipedia.org/wiki/Flintglas) and Krongläser in combination, to the effect of the CA to eliminate possible. In Achromats succeeds on the first level (red-green) sometimes quite good, but almost never completely and on the second level of the AC (blue-yellow) or less.
I know many, very expensive synonymous Lenses Manufacturer of the best, but I've never seen one without CA.
Therefore, it is quite unnecessary, is with this phenomenon, especially in huge enlargements of individual frames addressed.
Much better would be to look at the image content and on the film itself to concentrate, as continuing to operate pixel fetishism. "

Hm .. Lutz has made test recordings - these recordings are used to the technical quality to be assessed. If you act now to get rid of something like it would mean something for off-topic ;-)

For the handling of this camera, I can say nothing, but I fall on other Abstrusitäten, uszB if someone expresses how shitty it HD video images in comparison to its super> 12 M-pixel images of its DSLR camera are.
You my goodness, of computer science probably do not know, poor and ignorant are those posters, I do really suffering with their zero-knowledge ...

Note: Handling is not equal action!

Does have a little sloppy read. Nevertheless, I can with the posting of the slightest Deti not begin to say what he wants with the drift into the off-topic area? (apart from the fact that such a rigorous piece I ever find Apriori gschpaßig)

You my goodness, of computer science probably do not know, poor and ignorant are those posters, I do really suffering with their zero-knowledge ... Hast recht! 2Mpixel videos of an HD-Pimmelcam can never against a DSLR with Gigapixeltschipp anstinken! Who needs NEN good measure - and handling - at the Cam and NEN tilting display? The DSLR but looks fatter soooooviel out how silly! : D
Post? Ähhhh as I creep into my stuff Schittprogramm? Help - my Combiuter is too lame for the Schitter!
Antwort von domain:
Exactly it is Ricky.
Even with its 20 M-pixel cameras, they can not be more than 1920 * 1080 pixels, ie about 2 M-pixel on the best full-HD display monitors and usually have these images 5-6 seconds, so that they may interact what a data rate of about 0.5 Mbyte / s is actually much less than our brain can process.
Even the most modest HDV delivers more than 3 Mbyte / s with continuously variable images, such as the facial expression of a person and their sound.
Is interesting how incomparable standard of photography to compare the video section to be, I am always flat ....
We come but by topic. The HM700 could really be a sensation, synonymous of handling and size to view.
With XDCAM-EX Mpeg2 qualities and almost the EX1 / 3 series of Sony, will be very interesting, because it is not even on the ridiculous Endschärfe of images, such as Canon persuade us they want, but rather on the photographic qualities of the Pictures, softness, low sharpening edges, Durchzeichnung, Merciful in difficult situations.
Sony Does really excellent with the FX1000, a lesson for all other Manufacturer.
Maybe JVC has at least a little savvy and copied them?
Antwort von ed-media:
Nice that now synonymous Lutz footage from there.
The times I will be with the footage from England and USA compare
in any case, I have some other CAs already seen, this was
But Fuji s.der standard optics with a pre-HM700 and then when the final Canon 14xOptik there, let's next in the direction of CA, even the Panasonic HPX301 has CAs without CA-correction - Comparison with are all CAs away.
I think that the final Canon - not handmade Vorserienoptik the last bugs and no longer has the synonymous Camera similar to Panasonic is exchanged with the Optics and the CAs corrected. When I look at Phil Blooms material with his new Fuji-View Optics, which looks really great.
Interesting times would be the haptics of the HM700 Comparison to the HPX301 can I find much in the plastic look and thus synonymous Federleicht despite Camera volume when synonymous otherwise normal metal edition of the Camera on the tripod plate to the HPX301 plastic. How long in the everyday life keeps turning! I would be interested in how it looks HM700.
Thanks s.Lutz.

Antwort von ed-media:
Good, I fall for the shots in particular s.der satellite dish left and right marked CAs, as were the other CAs in the footage significantly less than comparison, I prefer to have footage on the one of the first HM700 models with the new Fujinon Optics approached.
And the new Fujinon wide-angle optics in terms of CAs looks better than those currently in Germany supplied Fujinonoptik (which comes from the HD2200/251-Serie).

@ domain:
I understand your criticism s.meiner not ;-)
For me there is no great impression Picture, provided significant technical weaknesses can be seen. I need me a whole day more or less well-made watch and imagery that makes me perhaps fussy than other people.
My criticism of a prototype s.aufgezeichneten material represents a potential weakness of the Camera, which is in serial production once again to check applies.
After all we are talking here about a camera, about the naked will cost 6000 ¬. This corresponds roughly to the street price of a SonyPMW-EX1 - and so must the JVC GY-HM700 synonymous to compare them.
My Conclusion so far:
+ More interfaces, better memory, better shoulder seat
- Dual power, weight, smaller, low-resolution and more exciting CCD sensors
I'm curious as to how the test results are out.

Antwort von ed-media:
Hi Deti well CMOS sensor is less noise and light are stronger, have themselves synonymous s.der HPX301 seen, bought one by Rolling Hutter (interfering with press conferences and sports).
On the subject of HM700 is heavier than EX1, many camera people want a heavier camera, because weight stabilizing effect, and most want a weight like a DigiBeta, where everything else is too easy.
The HPX301 comes to me synonymous with the size as a feather before. ;-)
Quite nice is the following link of Philip Bloom, a test of the JVC GY-HM700 - he has for his review and a series model of the material he found synonymous with Vimeo and - I think - the footage looks for Fujinon not bad.
Antwort von Lutz Dieckmann:
Hi,
So, I'm slowly think maybe it was a mistake the footage online. But I have so many mails about this, because I have it stopped.
Once again very clear: It was a handgebauter prototype. The first, it was in Europe. And it is almost 2 months ago. Each manufacturer compensates the weaknesses of the lens by software, which is normal. That of course does JVC synonymous. The CAs are stored in the camera not so ready to see how the footage of the prototype.
A technician from another manufacturer told me recently about how to do that, CAs are still easy exercise. Much worse are partial or blurred Auflagemaß. If you know you are surprised that we übehaupt get sharp images.
I personally think the first impression is very good, I like the Camera weight (it could be something serious) and I like the shoulder. The Viewfinder is awesome. Processing is one of the series models see the hand model was great. Whether the more CCDs really rushing remains professional testers leave, because let me have not been convicted without a meter. Especially not because of a footage which s.einem of muddy day within 30 minutes was rotated. There have been her studio environments. I therefore synonymous to moderation on this point.
I have just finished a movie with the EX1 rotated, synonymous a great Camera. But of course I have synonymous mistake ;-( trifles as always but I see it immediately, and that annoys me. Only because of the history of the finished film is my client is not. It is important not synonymous. I do not - he does not . The story counts, not the pixels. The customer is also Sony ;-)
With the HM700 will I be the next tutorials, s.Mitte April, with a pre.
I am curious.
Greeting
Lutz
Antwort von ed-media:
Hello Lutz,
for a pre quite OK. The software s.der still gefrimmelt is synonymous is evident, at least you have a picture of pre-to
a production model and because the camera is interesting, especially for current Berichtererstattung, documentary shoots, VJs and more. Even the JVC Vorführmodell are not perfect, as is synonymous already aborted one or the other, such as cable operator, etc.
PS: do you hold your own time mistake, but that you learn so synonymous! ;-)

Ever heard of what the over the Atlantic on the JVC cameras write that two chips side by side to act as a chip
ie 2 x 540 x 720th
Quote of DVINFO
"I think I can set you mind s.ease. The 100 series uses two 640x720 sensors mounted together so each sensor only had to run s.half the data rate s.would a single sensor 1280x720. Less speed = less power = less heat = lower noise BUT, getting both halves to match = not EZ.
I believe the 200 switched to a 1280x720 sensor which eliminated the matching worries, but reversed the equation: 2X faster = more power = more heat = more noise.
Actually the HD200 and the HM700 series all still use the 2x 640x720 with each side being processed separately. How do I know? I can still invoke the "split-screen ... even on the HM700 at +9 dB. The improvement happened in January 2006 when JVC QC Figured out how to best calibrate the two sides so that the "split-screen" would not show up except in extreme high-gain modes.
The core difference on the front end from the HD100 to HD200 series series was the jump from 12-bit A / D to 14-bit A / D. Of course it all has to go back to 8-bit for Mpeg2, but I think that the 14-bit processing simply holds on to more low-level detail (including fine noise) through the processing that eventually gets passed on to the encoder.
