Frage von Robert Niemann:


I would summarize times. I have the following known issues:

1. Smear:

2. Split screen:

3. Dead pixels:

(Compare: http://www.icexpo.com/HD100/HD100-normal-shutter.m2t)

4. Lens with chromatic aberration:

5. Lens "breathes" too strong:

Unfortunately, many go test reports in German newspapers barely a video on it. Therefore there is the HD101E now for a good 6,000 euros (including VAT), for example, 25p * cine support GmbH in Berlin (http://www. 25p-berlin.de). What do you say: If you strike or wait on the (presumably more expensive) counterparts of Canon (XL H1) and Panasonic (AG-HVX200)? I think the HD100, so synonymous has its advantages: The Cine-look of the videos, for example, is impressive, as is the handling of the camera and the manual lens.

Antwort von PowerMac:

Absolutely correct.
Especially current test reports of German "journals", such as the Digital Video Active will not enter into this at all. Are either completely uninformed or unwilling, to market to meet their journalistic principles HDV as well as the Manufacturer and hard to sell magazines, of course, without spoil one's mood compared to HDV.

I feel the same way as you, I'm confused. The supposedly objective, enlightened and "tested" the media not to mention the aforementioned disadvantages. Is it because of a duck, a self-propelling modern Forums Culture, drawn from random, isolated cases of general application to accumulated wisdom? Is the Internet Press inge received too pushy to individual cases?

I think that the above problems, all the systematic nature.
Say the lens breathes whether the design-ever.
The split screen is always there, through the "parallel" reading can not be otherwise. Only not everyone is able to provoke him really synonymous, since he might not bring in situations with his filming where you may encounter the split-screen, or some simply attaches under the delusion HDV no objective standards of quality and prefer more of the (specified) Resolutionerfreut .

Of course, these are probably only small drawbacks. Nevertheless, the camera is good and cheap. That conceals much of the Manufacturer is synonymous legitimate. But stupid magazines that reach out with a single word. Either there dictated the advertising department, the sales statistics, professional incompetence or excessive HD euphoria.

6. The battery holds only 40 minutes. (Comparison to the experience gained from SonyHVR-Z1 Battery included stops at six hours.)

It is interesting that the digital display in the "Videoaktiv" an abbreviated version of the test report is of http://www.film-tv-video. Reduced in the sense that the issues raised in the original article quirks of HD100 were largely edited ". I think this says everything about the process of professionalism / independence of magazines such as "Videoaktiv digital". It is a shame. I am almost inclined to consider law to what extent can these magazines call the light of the described process in general as an independent.
In the above-mentioned problems are not isolated cases. Regarding the issues and smear split screen now are even official statements of JVC (Smear: manual, split-screen: http://pro.jvc.com/prof/Attributes/faq.jsp?tree=&model_id=MDL101539&itempath=&feature_id = 13 # chips). Also I would think that the problems are not just "small costs" are. The split screen effect interferes with viewing the videos produced by lens chromatic aberration, making the possibility of color correction in post production to a virtual impossibility, and the Breathing of the lens during focusing leads to a zoom of the can be willed rarest of cases.

Hello,
A few days ago I getest the Camera and the only one company in the customer room and all three errors are directly encountered. Regarding the division of the picture, I was assured, however, that only in the earlier models, and the case would be resolved at the next delivery cameras. Has anyone at this point experience?
Another weak point is the extreme pumping of the lens, it is not innenfokusiert.
What bothered me, but also, and makes me doubt whether the camera is the right choice, are the weaknesses of the viewfinder and Shuttereffekt at 25p.
With or without focusing sharpness Wizard remains a poke in the fog. Difficult, difficult. Ect, and with fast movements, corridors, people tracking. shuttert the camera like crazy. I do not know whether this is fundamentally a problem of the 25p mode, or whether it is reinforced by the image transformation of JVC and is therefore home-made.
What is considered extra. In the prospectus states that the camera draws in 720 at 25p and can output 1080i synonymous, which converts various formats in real time. JVC corrected to me today, this would certainly agree, but does not apply to digital connections, ie. the signal is not s.der HDV / DV in socket, but only s.Komponentenausgang digi will be converted to analogue / and must then be converted back.
The desire of many, one turns in HDV and erstmal gives the signal to SD / DV over Firewire is definitely not.
Another downer on the TC, I can not access through an even out.

The video digital items is not his money worth. But will the Manufacturer, the newspaper pay for the promotion.
You write of weaknesses, but does not say which.

Hello all,

naja on the cheap Fujinon Lens gibts so many bad experiences:

Odr Canon Fujinon

Maybe there's in the near future as in the DV 5000/5100 synonymous several suppliers of different models, or lenses that are 100 designed for HD to get at least the fringing and Farbfehlerproblem under control.

But one must be honest, the VAD is really responded to the above problem (and has called for new Fujinon Lenses of). Ok, unfortunately, it was s.end runtergespielt again and noticed that it only comes in very fastidious customers grudgingly.

The Battery was already listed as Cons.

The problem of smear me but even the appearance of the Mag's somewhat shaken, because enough test pictures (many months here), among others, with unique Slashcam Smearproblemen were seen. (I had expected with only one Vorserienmodellfehler)

The sound tests in the current edition have been very successful, but by the HD 100 Test and the complete beginner Blackout (Canon MV-830 and JVC GR D 270 had no memory function), the level goes down significantly .....

Well one of Stadement VAD would be interesting times

Antwort von Robert Niemann:

The split screen problem has not been resolved. Anyone who claims otherwise, saying the truth. Obviously, it is synonymous not solve the problem, give the HD100/HD101. This official statement of the JVC (see link above): "This is a characteristic of the CCD readout method employed in the GY-HD100U [...] This is not a defect." However, several users have reported in U.S. forums that the split-screen effect was minimized with a firmware update that he had not entirely disappeared, and under certain circumstances, one could always bring him back. As the sales of the HD100 with notification of the problem is said to have significantly minimized, it is quite likely that soon with a follow-JVC model comes on the market. Rumors in U.S. forums accordingly this could already be next April (2006) the case. In any case: by the JVC so publicly expressed, that the split-screen effect is not a defect, the company secures s.gegen buyers who demand because of this issue a complaint to their woll Camera (ed).
The viewfinder is a weakness of all the "cheap" HD cameras: The Resolutionist simply too low to be able to assess whether the desired area in the picture is very sharp. But I think the Focus Assist with the HD100 here makes a very good job. But come s.einem additional monitor during shooting to well past little, if one wants to be sure. Only Canon offers a reconstruction of his viewfinder to the CRT monitor (for the XL H1, just as it was synonymous with previous versions of the XL-case / is).
The Shuttereffekt at 25p is not a bug, rather it occurs in all 25p cameras. It's the same effect that one of the film projection synonymous knows her, just with the difference that television lines will be constructed in a different rhythm than film images are played in the projector - thus showing the Shuttereffekt on a television / monitor more evident than on With celluloid of recorded movie screen. To minimize the "problem", but offers just the HD100 to a so-called motion-Smooth function.

Antwort von WoWu:

I was interested in pursuing the course of the discussion and can only say .... After I spotted the material to a rotary 3.monatigen time ..... The Lens s.der HD-100 is just about the worst thing I've seen so far s.Objektiven. The pictures of the little Hd GD1 or GD 10 are better than the HD 100th Has it to do as we did at the shoot in South America, with lots of light, all 11 blurred images above Aperture!! The halos are intolerable, and thus make the zoom is not really usable. The zoom goes wrong and does not allow for real centering. ..... I could now write it next ... but I think it goes .... The han-dling of the camera head is quite good, so JVC meets little guilt, if only the Fujinon lens would not be impossible. They probably deshabl with high-pressure s.Nachfolgeobjektiv HTs18x4.2BRM-M48 and worked with the ACM-17 adapter, the way to the 2 / 3 "lenses freed.
So who plays with the idea, buying a GY-HD100, it should consider it again.

Antwort von closeup25:

We can use this observation - one of the first testers and journalists of the relevant screenshots - not even acknowledge. We have bought an HD-100. But not without updating before the camera again and leave to set. Meanwhile, we have two commercial productions (1x studio, 1 x external rotation in London) with the camera behind us and are extremely enthusiastic. The pictures are superoberamtlich (of small mistakes after the decimal point apart in the lens ...). As soon as our time allows, we will gladly replace by uploading the proof. In our opinion, must not hide the camera in front of a Varicam ...

Antwort von closeup25:

Have to support our own experience, once again, here is a "small" test of people who made the effort, the 4 new HDV camcorder (Canon, Sony, JVC, Panasonic) with CineAlta and Varicam with an extremely professional meticulousness to compare. A really worthwhile read, as we think. English skills are useful:

Hello,

It developed into a small religious war. JVC vs Sony.
I purchased the JVC - Turn primarily as DV, but at einwenig HD synonymous with it.
So that everyone can even make a picture, I asked some HDv 72030P clips online.
Recommended only for flat rate;)
www.machdas.de/Seiten/hd720.htm
I will be the suitability of the HD camera test in more detail - according to the NAB.
But this much Vorneweg: What do you expect for 4500 euros? The lens can be quenched at this price no HD Lens. From my SD lenses cost more than the 4,500 euros each.
I think the JVC is a good price / performance ratio. In DV mode I now have something with her was rotated and disappointed yet.

Antwort von closeup25:

Hello ChB,

this is not a religious war. The Thank God there are no longer in Central Europe since 1648. The JVC has a completely different oriented aesthetics, which is much more committed to the film image as the video report. Just look through the test, please, I've posted in this forum.

Moreover, we turn now 10 days since a television documentary with the JVC in Vietnam. So far there are no complaints (knock on wood ...). Although the conditions are sometimes far from ideal. I will refer to the result as soon as is the send (broadcast in SD of course).

DV Shooting with the HD-100, incidentally, I would not recommend it. Dear herunterkonvertieren HDV and the editor. Is 1000x better. Believe me ...

Christian

Antwort von ChB:

Hello Christian,

I am sure that it works in Vietnam synonymous.
Perhaps I should turn synonymous to HDV if FinalCut would support native finally 720 25P.
Thus, it remains at erstmal DV 16:9.

Antwort von prem:

Hello ChB,

Canopus does this since 3 months. Looks hammermäßig. So far we have been working with Avid, but it looks like, which are currently fully absorbed so to digest its acquisition of Pinnacle. In addition, at least Xpress Pro / Mojo in the foreseeable future will be offering any HD Preview, and that's what's on after all ... What good is a 720p25 Suite when I can see the result until after the Masters.

Antwort von Screenhorn:

Hello!

We use a production company since September 2007, a JVC GY-HD 111 is a many of our shoots.
Referred to here "defects" in this model, we have not been able to find. We shoot at the time of this camera with three industrial promotional films and a great documentary about Istanbul's artists. Just the shots at the VB in Istanbul in October 07 were simply terrific. With the recordings of the JVC to make a very "cinematic" feel (at 25p and 24p anyway) and therefore may not be available for all TV format 100%. On the other hand, we have kolegen that rotate quite "normal" 30s or 45s documentaries for HR or SWR on this camera, where else Beta SP or DVCPro 50 was used. And on the setting of the JVC DV!

The Handlicng the camera is wonderful, and if a man of "great" comes, you can find your way around easily. The processing of the camera is, except for a few weak spots, very robust and solid.
Have very good pictures but do not always ewtas with the technical inner workings of a camera, but synonymous with the fact that they can use professionally. So when I lead my shots s.einem "real" Lens or s.einem endless rumleiere Plastikrad, it also has a lot to do with the quality of the images.

The battery capacity is somewhat weak for the younger generation, for the NP-1 generation habit.
Batteries tend to arise because the amateur level, they need a few charging cycles to achieve their full capacity. Then hold approximately 60-80 min a 3800. Significantly less in permanent use of the zoom motor, because we have indeed a mechanism to move. But the professionals know, yes.
As a complement, we have still one of the four original Batteries six copies on Ebay for legendary p.St. 3.60 (Original JVC approximately 100 ¬) called in, who, surprisingly almost the same performance as the originals. In all, however, significantly cheaper than the expensive adapter for the equally expensive professional parts.
And easier, because the top-heaviness has dealt with us with the flanged Firestore. The prof. Batteries she would soon be too long and too "arschlastig" are.
Our equipment is top heavy anyway, since we assembled a large compendium 6x6 double filter with top and Seitenflag have. Man kan but wonderfully s.Rod stabilize the camera for the lens hood / Compendium with his hand.
And the shoulder thanks ...

Conclusion:
Camera class with very very tasty "film look", which naturally has its faults. But if synonymous in such forums, the war still rages unpaid brand fanatics who bomb themselves with technical data sheets and statements never been tested, yet is ultimately the quality impression Feeling Based on the preview monitor!
And please, what camera is infallible.

For the P2 fraction: I just need one days in order for a turn continues to Spain, because the P2 card was not legible at once, or broken.
The JVC solves the problem of parallel: DV tape and Firestore simultaneously, thus always "safe"!

On average, we now share because of the ingenious hardware discharge by the software to Grass Valley / Canopus Edius 3 or 4
No problems with any HD material, only 24p the Calculator something to its knees.

So far, so good!

Liebe Grüße,
Tom
