Infoseite // GR-PD1 - or would you prefer "real" HDV?



Frage von Martin:


Hi All,

For some time, "I stand before short" * g * investing in a SonyHDR-HC1. The thing is I simply still too expensive, and I can not reconcile myself with the thought s.The interlace Probematik quite.

Now, the JVC PD1 for the $ 1,000 is to be had. The concept was probably not fully understood, therefore, my attempt to highlight the main points for me:

1. The Optics of the PD1 seems to be at a level higher than that of the HC1

2. The recording format of the PD1 is 625/50p "- that is neither SD nor HD. How should I understand? Are recorded in 16:9 just about 1111 x 625 pixels, and the 50 times per second in MPEG2? If so, that would be even relatively close s.720/50p - so that I would come again to 32% more pixels. With 1111 x 625 but wärn's already 110% more than PAL 768 x 432 in 16:9.

How is it that thoughts picture?

The Aufzeichungsformat of PD1 is always 720x576.

Ok. What then does "625/50p?

Antwort von Marco:

Sun is called the norm. PAL SD is described as synonymous 625/50i. In the case of PD-1, it is just (optional) 50p.

Thank you! If this is not absolutely logical that a format with 576 lines "625" is, but then I understood that now synonymous.

Too bad, then I just wait next ...

"Is not absolutely logical that a format with 576 lines" 625 "means"

Meanwhile, no more, but - correct me if I'm wrong - this definition comes from the analog storage. There, a PAL signal has a total of 625 lines, of which only 576 "active", will be used for actual image content. In the remaining rows are untergebraucht other useful signals, such as timecode and Teletext.

In a digital processing system and recording medium but is playing a role in the active image content, which are synonymous "only" 576 lines included in the usable Digitalsierung. Things such as time code can be transmitted in digital environments and different store.

Hello you,

even the original manual that can not quite convey:

Aufnahmegeschw_horizont.L_Vertik_L_effek.Bildpunkte_Bildformat-B/sek_Scanmodus
HI-RES____________720______576_____1280x659____16/9______25_____Progressiv
PS50_____________720______576___941x485/839x576_16/9_4/3_50____Progressiv
DV_______________720______576____839x576______4/3_______50____interlacing

How can it be when at 1280x659's Palband "will always raufgeschrieben" with a Resolution720x576? Is that a projected study of JVC, as well the HI-RES mode auflösst?

Next HI-RES is a tape-recording in MPEG 2 format (576p). The camcorder records the signals in progressive scan mode on (625 lines per 1 / 25 second at the recording / per 1 / 50 seconds when playing in one pass)
The mode HI-RES offers a higher image quality s.Aufnahmen in PS 50 and DV modes.

Well, the only professionals can probably understand ....

So first of all: it just had to PD1 long time, many speculations as to what exactly is recorded onto tape. yes m2t, with data rates of 18.3 Mbps of "real" 720 25p. Therefore gabs well enough to speculate whether this is not material to the U.S. 720p camcorder is taken, and "somehow" runtergepatched.

And there are even PD1-blogs that will be recorded on tape via firewire 720p.

But it is with some certainty so that is recorded on tape actually only 625 50p. So, 720x576 pixels, but in the HiRes mode with 25 progressive frames. Means in HiRes mode high resolution filmed very well - almost with full resolution is HDV1. The recording is, however runterskaliert.

How do we know? Well, simply because tests showed that one in true 720p Resolutioneben material can not play back via firewire on tape, but very material, which is followed in all settings 720p, but with 720x576 pixels.

But, the PD1 HiRes material shows a significant resolution, as I describe in the video meeting more often. In fact, the material has significant reserves, and can be easily scaled up to 720 25p right - synonymous because of the progressiv format. The distance to "real" 720 25p material from a JVC HD101 showed surprisingly little distance from the material of a PD1. Nevertheless, one must point out that the PD1 halt is not a HDV camcorder, but assumes a kind of intermediate position. In any case, it beats almost any SD camcorder in a similar price range, I know. And is thus at Saturn for a buyout price of 990 euros a genuine bargains.

Further test details here:

Test movie to download (wmv, but in 720p Resolutionhochskaliert, respect, size of each film about 60 MB):
http://www.videotreffpunkt.com/thread.php?threadid=1609&boardid=47&styleid=6

Synonymous and one should note that the meeting described in the video editing software through use of course, but more upscale.

Hello you,

Wolfgang's JVC / Vegas knowledge is already enormous.

Well you're not a professional, but becomes one if you are overly diligent and conscientious with the matter deals!

I had the GR-PD1 recently when Blödmarkt and was now in the hands of the depth of field (depth of enthusiasm). Although I have a Canon XM2 (she has not been a better picture, at least in SD), but as I said the depth of field is really nice, and the zoom ring and the optical image stabilizer, at least in the price range around 1000 ¬ ... ;-)
