Infoseite // HDV - AVCHD quality difference visible?



Frage von klangbild:


Good morning to the forum!

I am planning to buy a new, semi CC `s. (This is to succeed synonymous excellent low-light shots.)
With bands I've had no problems. The time to capture I take. My new computer editing "creates" but synonymous AVCHD footage.
Now I had the opportunity to conveniently come s.eine Canon XH A1s.
On the other Page, but waving the avchd cams, like the new SonyHXR NX5.
Now my Question: Is for "John Doe", the one home-burned DVD or BR on a standard LCD or Plasma looks at a difference between 1440x1080 (HDV) and 1920x1080 at all VISIBLE (not detectable)??

Since I would be interested in your opinion very much!

Regards,

If both cameras work best in each case (eg if there are two high quality Henkel men), may, at BR a small difference remain visible - at least in a direct Comparison. Practical relevance is the difference really not. XH A1s and one is still much sharper than much of the cheap consumer camcorder that can, according to data 1920th
For the DVD edition, which is reduced to 720 pixels, played in 1440 or 1920, of course, does not matter.

Talking about 1440 in my view that it is not really into conformity. On the BR Resolution1440x1080 is allowed but only in H.264 Compression and not in MPEG2, so synonymous if your program can output HDV editing with smart rendering, you have to compress it for BR again new. And Web video, etc. You are of 1440 to 1920 will have to extrapolate.

Complete Quark. HDV IS a standard, fortunately, as well as HDCAM, both working with anamorphic 1440, synonymous XDCAM HD. Many other professional formats as well, even in movies you see anamorphic images. And every day watching TV, when watching any 16:9 DVD. Always anamorphic. Not really-standard? Ah yes.

Apart from that, I say, the difference between AVCHD and HDV in the consumer class is practically invisible, or at least not relevant. For smaller camcorders can occur in HDV times to blocks of education, with AVCHD to 'blur Clouds ". Both falls only when you analyze still images, but video is now even a motion picture medium. And as I said, "Full HD" is a gimmick, not a cheap camera creates this optical Resolutionauch only partially synonymous and can NEVER make fullest potential, the quality of a Blu-ray.

The decision to have a camera after all other aspects are: post-production workflow, recording medium, ergonomics, quality of Optics (aberrations in wide Anglezum example). Let me see the bare facts aside, this leads to nothing.

The practice in the professional Blu-ray production is likely to be even extrapolate material from 1440s to 1920 cameras-Width. Can be done naturally, and it will look better than 1920x1080 from consumer cams.

However, it is perfectly possible with Blu Ray 1440x1080 - Create without problems and synonymous with programs that pay much on the specifications, such as the SonyDVDA. And the thing of Blu Ray players will play very well.

The real question: So if you use an A1, which does have a good image quality, and 1440x1080 all very well, uses - then you have probably no worse picture quality than AVCHD camcorder with many, synonymous if the record technically in 1920x1080. It is indeed, in sum about the optical quality and the quality of the signal processing, and there are devices such as the A1 not been bad. If you have to manual settings on a lot of importance, and which uses synonymous, then it is a device in any case a different class than most of today's AVCHD devices. However, the A1 is bigger and heavier and bulkier synonymous, and is about to museums and attractions for even more recognized as a professional machine (and then they leave a film not so often). It just depends s.was you want.

The "standard" (ie the profiles MPEG2 MP @ H14 defined but not 1080 but 1440 x 1152, ie four times the SD resolution.
So it's not quite "-standard" when someone from a Picture croped.

Now sometimes slow for the record ...
I authore a good six months since my HDV movies in 1440 as MPEG2 on Bluray discs and they lead by Bluray player before on screen.

And it should not be allowed as per specification?
Now I'm ready ...

No idea who is right now. I can remember synonymous weak that allow this lack of logic (the 1440s-Resolutionnur in conjunction with AVC) shortly after the publication of the Blu-ray standard was discussed in various forums. But perhaps the standard has been reworked in this respect.

Antwort von Alf_300:

You have to gaze the finished MTS, whether because the format is then synonymous still 1440x1080

Antwort von Jitter:

It does not depend of HDV and AVCHD, but the signal processing of the camcorder. The test slashCAM pictures show that good HDV Cams (Canon HV 30 / 40) add, despite nominally lesser Resolutiones with every AVCHD cam, even better than current AVCHD camcorders are of Canon.
Even when there is BluRays HDV with no problems. Here I can confirm from personal experience all the other only. Make your decision solely of the facilities of the camera and your ideas and not dependent on the format.

Quote: illogical to allow (the 1440s-Resolutionnur in conjunction with AVC)
So illogical it's not because Blu-ray not in MPEG2 specification according to the BR-MP @ H14L supported. (But only MP @ ML and MP @ HL (also 1920)).
