Frage von SMY:
Hi,
I use one SonyHC7 and cut with CS3, s.Schluß it on Blu Ray exported (currently as AVCHD via MovieFactory). Now, I have noticed that after capturing fast pans s.Qualität significantly compared to the lost tape. Is this a trick? Take for example, Concept Media Cineform or something? What is the path with the least quality loss to AVCHD / Blue Ray?
Thanks for any advice!
SMY
Antwort von j.t.jefferson:
But you write:
that after the capture fast pans s.Qualität significantly compared to the lost tape Can not be, because it is capturing only a copy operation!
You mean, perhaps, that the preview in the small Picture of NLE bad?
1. The Bildaualität you can overlay on the small preview in PPCS3 set ---> Manual!
2. Best Quality You can get by GraKa hardware preview to send a second monitor. Of course, synonymous here the picture of the quality of GraKa and the Vorshaimonitors from. Best Quality You can get the preview output via DVI HDTV s.einen send!
Antwort von j.t.jefferson:
Ok, but I've synonymous with the final AVCHD synonymous with the blurring pans, I think, this is s.der conversion (?)
Date:
- Project in CS3 1080i create, capture with HDV
- Exporting with Media Encoder, 1080i, 25 Mbps constant
(alternatively, it had been synonymous with the MPEG2 Blu Ray tries profile)
- In MovieFactory AVCHD with 18MBit constant
Antwort von j.t.jefferson:
And now stuck in a Blurayplayer and the quality is excellent.
Knows what you do not then the AVCHD DVD ... guckst, perhaps only on the PC monitor and see then interlaced picture.
Schimpf, but say virtually nothing about the W-questions.
Antwort von Axel:
Is it not possible on a Blu-ray simply HDV to leave?
Antwort von immanuelkant:
sorry, at the risk that I have your problem is not fully understood and also type in:
But could not the following problem: HDV cameras for the European market work according to 1080i @ 50Hz (25 frames per second). BluRay players know only the American-Japanese 1080i or 1080p @ 60Hz with 30 frames / s. The "recorded" BluRay discs for Europe will be synonymous with 30Bildern / s delivered. 50Hz-material (25Bilder / s) of the HDV Cam with 60Hz (30Bilder / s) will play in movements such as panning the infamous Microruckler ....
Antwort von SMY:
Thanks for your answers!
However, it is not Mikroruckler or interlacing. The following example: Underwater recording of a coral which is very finely structured, then easily swivel.
If with HC7 via HDMI directly to television (full HD): synonymous with the movement there is still the fine structures.
Even after the capture (in any case looks like this), but in any case after the burning to AVCHD and viewing on television during the swing motion can be the fine structures no longer recognize. Overall, the picture is no longer synonymous so vividly.
Does this next?

@ SMY
I've now understood that you aufnimmst AVC and HDV on to work on BlueRay then another.
This is big crap, because you all the benefits of AVC (MPEG4) to the moment in a ton of kick, where you on the "coarser" MPEG 2 reduzierst.
Especially when you described the applications of course, lies one of the strengths of AVC.
I could here you all detail down to pray, but I get into trouble only with the HDV Group. But there are a lot of Topics in which I have already explained.

is an HDV cam, which you must have read about. What the thread starter says, is that the
direct conversion of HDV to H.264 to artifacts
- And here a question s.dich --
s.muss
b)
For me (Final Cut Pro with Compressor or Quicktime Export Preset with "H.264 for HD-DVD") provide for the different disorders. There are actually pixel blocks (particularly on large dark areas), which is build and then disappear.
For an answer, what's wrong and how to prevent it could ever thank you.

@ Moin Axel
jau ... that I had not understood it ... HDV and what the corner is concerned, not angry, but I have in my life yet not too much secrecy for new experiences. But we must also synonymous such experiences. And I will not synonymous HDV verteufeln, I've always liked synonymous made ... but the time will not stand. As I said, was not meant evil.
What SMY, it is likely on the way up, so of MPEG2 to MPEG4 after deterioration not materialize, because it's a up-sampling is the tools and everything and it even finer than MPEG2.
This is synonymous to the observation we have made such a test.
First tip: codec is not really good. Cyberlink or MainConcept builds really good codec, which is synonymous such demands.
Axel, I have unfortunately the question is not really understood.
But always indicate pixel blocks to a procedure to abort. The bandwidth may be too little or too little time. The reason for this can be images, the encoder in the "stress", that is motion blur + is problematic.
Give a look to the sample slightly "Noise" on it (Grain) (That would be sharp) and look, whether it is gone.
If I misunderstood the question now was, I would ask again for a short notice and a more concise explanation.
Antwort von SMY:
It is true, the HC7 is filming in HDV.
@ WoWu
Cyberlink codec what do you mean? I know only those of MainConcept (MPEG Pro HD) and the Aspect HD?
Yesterday in the same direction and started a thread paralele ...

Bin for each tip very grateful!
Antwort von wolfgang:
So I wonder how accurate the assessment of the material after the capturing is done - and how the material with the original material on the tape is compared. It is that HDV for fast panning or movement less sharp than in the motifs - basically what happened to the GOP structure and the Halbbildverfahren comes out.
But only by actually capturing it should be no quantum leap that is a pure digital copy. I could already rather imagine that this is a problem from the preview editing program to act - because CS3 is not particularly famous.
Or the assessment of achievements after burning to a DVD AVCHD movie using the distiller 6 +?
So, as I understand are 2 Encodierschritte - to m2t out from CS3, and then encode with the AVC encoder in the film distiller 6 +? For the question asked would you want to know at what stage of the process the quality is lost.
Apart from the fact that I wonder why not the same from CS3 to AVC encoded is - because the film distillery this material can then burn to disc without further encoding that will only cost quality needs. This procedure was described Bruno times:

Hello Wolfgang,
sounds very interesting with the export from CS3 with AVCHD. Did I understand correctly that this is only with Dolby Digital going? Not really wanted to buy expensive Dolby encoder ...

Give a look to the sample slightly "Noise" on it (Grain) (That would be sharp) and look, whether it is gone. Several passages, the highest level of quality and a high data rate (from about 10 Mbps for half image size), the pixel blocks
almost disappear. The first division is for 2 minutes over 2 hours to render. The original HDV has the 25 Mbit. Is perhaps because of the error?
You have right, incidentally, that the clip is a lot of blurring
and movement.
However, only really dark parts affected.
I hope I have you with the correct Grain: The HDV - video will be with, probably very subtle, Grain newly rendered, and then exported? I will try tomorrow. Meanwhile, many thanks.

Gruß Sascha As far as I know, allows synonymous CS3 is still only 3 test exports of AC3 5.1 material - and then you need to buy the 5.1 encoder. I'm not sure if the AC3 with at least 2.0 in CS3 unlimited possible.
Only in principle: you should make sure that you do not encode a multi-orgy in your workflow einbaust, and as few as possible Encodierschritte sets. The cost of holding the quality ...
Antwort von WoWu:
@ Axel
Yes, that was understood ... versuch the times, you make it easier to estimate the motion and the Ecodierprozess is not aborted.
The bodies with the dark, it is clear ... Reasons I do not, because then everyone again "impractical" calls.
In any event, we always had good results with so little tricks, if it "difficult" pictures.
Antwort von Axel:
@ Wolfgang.
I have a 20 seconds excerpt of much blur (macro), movement (chopping onions) and dark spots contained so treated, as you've described it, and, Wow! An equal, almost somewhat calmer than in the Picture Original HDV, at 10 Mbit. Must still experimenting with how far the Grain, I can go down, because if you look
closely, he is synonymous after the conversion, a bit like Gain Noise. Once again, thank you.
Such tips can be so in the Book with backgrounds explained.
Antwort von WoWu:
@ Axel
.. I am pleased that it went well.
Such tricks you do not have to explain more if you understood my book, because since then to get out of all alone.
If the principle of MPEG understood, we know much more precisely to deal with it.
In any case, I am pleased that I could help you.
