Frage von Funkfeuer:
Hello,
I have about my HDC-HS9 a few scenes on the internal HDD.
If I use my camcorder s.den TV infectious, the picture quality is very good.
However, I would like the scenes in this quality synonymous s.PC have. Furthermore, I would like my films on DVD burn, so that they are synonymous on commercial DVD players (eg for Known ,..).
The software converts this quality in MPEG2 quality around, if I create a DVD which will (on PC).
MPEG2 is a - in Comparison to AVCHD - very poor quality.
That annoys me, because the camcorder was a better quality has ... :-(
1. Question:
Is there another way to AVCHD quality synonymous s.Freunde and acquaintances pass without my camcorder mitgeben need?
2. Question:
The camcorder records the files in the mts or m2ts to. Can these m2ts or mts files synonymous edit, or can you only MPEG2 files to edit and complete movies together in between?
3. Question:
Sometimes the camera saves the files as mts - sometimes as m2ts. What is the difference of these two file types, or when is the draw?

Video DVD for normal living-room DVD player are mpeg2 and not "High-resolution (high definition) as the cam records yes. This is the standard of DVD-Video. You can of course always the AVCHD clips on a data DVD burn. This is in the living room but player does not play (there is so "Special Editions", Blu-ray player or a hard disk player then it may partly or fully, even s.DVD). There are, however, synonymous vimeo.com and other video portals, as you can at least 1280x720 with video (more than DVD-Video) to upload.

In order to play AVCHD s.PC and edit it needs a powerful PC. The newest and best is still not nearly enough. And of course it needs a cut on the AVCHD software "understands". But you can convert the AVCHD synonymous (most-Cam Manufacturer offer appropriate tools) eg in mpeg2 or avi or quicktime to see it better to be able to process at a weak PC. One speaks then of minor trans-synonymous coding loss because the clips of one format to another modified (converted) will be. But since s.Schluss yes a DVD, or maybe even a Blu-ray (which mpeg2, h.264 (AVCHD) and WMV-HD and VC1 support) is in my eyes at the moment, perhaps not a bad choice mpeg2 (HDV is synonymous mpeg2, even EX1 / 3 to make mpeg2). I make any bet you and my colleagues look at the appropriate mpeg2 and AVCHD no difference. Basically, you can edit everything with anything.
mpeg2 is not very poor quality compared to AVCHD. Both have advantages and disadvantages. Annoyed you do not have a few pixels but you prefer to concentrate on a good picture, good cut and of course a good history in the shooting.

But this is often in the forum already done, so I would ask, but once the search function to use if you are interested in details to come.
But the allegation, MPEG2 was not worse, as in the Middle Ages, the claim that the earth was flat.
Only time will tell.
Question 1:
Yes, it's of course, presupposes, however, that for example you have a BluRay authoring and content available on DVD (BluRay) mitnimmst ... Players naturally assumed. PS3 is of course best of all synonymous.
Frage2:
Yes, the data can be synonymous edit if it is not yet synonymous so many programs out there, but Vegas 8 does the job well-excellent, as one hears, but synonymous Manufacturer offer other editing programs that you can use to be sniffed. ADOBE in its latest version also, however, requires a certain graphics card required.
Frage3:
Why the files of your camera may have different names so I'll not answer without knowing what it is stored.
Basically the MPEG2 transport stream, but only the "packaging" in which the MPEG4 AVC H264 packages are stored and has nothing to do with the MPEG2 encoding to be done.
Antwort von Marco:
Are you sure that the camera is the video as synonymous. M2ts stores, or is that the result after import by the software, which belongs to the Camera?
Actually draw the previous AVCHD cameras themselves only. Mts on this format and takes into account the 2 GB limit the volume of such cameras. Only by the import software will then normally be. M2ts format, eg on the NTSF-formatted data files into blocks larger than 2 GB can be summed up.
This allows. Mts ie unfinished structures include file (as shown on camera media), while the conversion to. M2ts file structures, where appropriate, be added and completed.

Thank you for your answers!
Since I'm here in the forum set arrived with so much concentrated knowledge :-) :-)

... but then my calculator or my Brennprgramm synonymous eg Blu-ray blanks can describe, or can do any burning software or burner?

Panasonic has launched a program supplied by the mts into mpeg2 files converting.
I've synonymous found another program that converts to avi - but I bilde me that avi is worse than mpeg2. Is it or is just s.der Calculator's performance?
The statement is but a few here in the forum rather regurgitation, although your observation is absolutely correct and would make itself synonymous reasons.
That was not my intention ... I have only been about 2 weeks (for the first time) a camcorder and have from my naive perspective described first impression ;-) Maybe I should be synonymous another program to compress care - perhaps the software is synonymous not so great .. ?
... Only by the import software will then normally be. M2ts format, ...
Yes, this may be that I already m2ts file on my HDD Calculator have seen. Then, the import program apparently converted the file.
Well - to be synonymous to come ...
... Yes, the data can be synonymous edit if it is not yet synonymous so many programs out there, but Vegas 8 does the job well ...
There's actually synonymous Programs, which provide similar on Linux?

You really attack anything on what to MPEG2 and AVCHD said.
AVCHD movies when converting to MPEG2 worse. Conclusion: AVCHD codec is the better - OK.
Conversely: MPEG2 movies when converting to AVCHD synonymous worse. What we infer it? MPEG2 is the better codec?
But more likely, that the conversion of a lossy codec to another lossy codec always brings a quality deterioration.
Antwort von WoWu:
First of all you have right, under a transfer may be the result not be better than the worst algorithm allows.
But even this "bad" quality is not achieved, because the first algorithm the starting material was not as good as if it were a camera image.
But the shot that you draw, and very true Not at all.
Each original signal by the MPEG algorithm is only as good playing, such as the fine estimate of the algorithm allows it.
In H.264 1 / 4 pixels and a macroblock size of 4x4 pixels for motion estimation to 16x16-pixel block size for MPEG2.
(This would mean that the artifact that is synonymous sizes (blocks formation) in MPEG2 16 x as large (16 to 256 pixels))
About games, I now have a signal of a fine (4x4) Resolutionin a coarse (16x16 resolution, my movements accordingly ruckiger. "Also my screen resolution and possibly artefact formation (in space) will be larger and thus more visible.
The picture is so much worse.
But now I take an original image simultaneously in MPEG2, so are the frameworks of already beginning "ruckig" and with large blocks. About games I put in a higher resolution codec, the ruckige movement, which is no longer synonymous liquid and my 16x16 blocks remain synonymous received, quite the contrary, there are the small 4x4 blocks added. In this respect, the picture that is synonymous not better.
The examples are now in a greatly simplified soon in real life to play a whole range of other parameters into it. How do I use in an H.264 DCT with significant improvements (I) DCT, in the event of a transfer to regular MPEG2 DCT is brought. This leads to error propagation in the B-frames.
From a Bildreferenzierung, on 16 I-frames relates, a Bildreferenzierung, consisting of 1 I-Frame besieht, with the result that periodic processes no longer be displayed correctly.
A transfer according to MPEG2 is synonymous is not advisable, as in-loop filter, the edges of the macroblocks conceal.
The MPEG2 encoder means it needs a longer in the signal assignment in the macroblocks and tends result of time overruns in a real-time method for demolition and thereby to block additional education.
I could be the number of examples still "endlessly" to continue, but it was me just about the representation of the principle. Also why the MPEG2 with MPEG4 after less überspielungsbedingten losses is tainted than 4 After the 2nd
The IRT (Institute for Radio Technology) is now 15 years do not become tired, the broadcaster prior to the cascading of reductions to warn ... and I can only say: with law.
But when the video is something apparently not yet arrived, as is kicking out and her Transcodiert and most synonymous Intermediate reductions are, with similar effects and if it still from MPEG into a wavelet-based algorithm is .... na primavera.
So, you see, of MPEG4 to MPEG 2 should you deliberately let their fingers, if you value image quality on sets and the observation of Chris was very accurate and well observed.

Antwort von Meggs:
I've already done well in both directions. My experience was to that of the undoubtedly existing quality loss appropriate settings sooo not dramatically fails.
It is the HDC HS9, a beginner AVCHD camcorder class of 500 ¬. The thread starter found this picture very well - he has no exaggerated claims. After converting to MPEG2, he finds the picture is much worse.
I suspect that the encoder used is lousy, maybe so will the video of HD after SD converted, who knows. But I do not believe that this user a carefully executed conversion of MPEG4 MPEG2 as so dramatically would feel.
Antwort von WoWu:
@ Vaio
In large parts of your postings you have rights and I am fully with you, but the problem is precisely the fact that precisely through this "but for the last Consumenten" - keeping the industry is synonymous encouraged, nothing better on the market and the vehement demand of Consumenten for more resolution, better colors and professional work only with new marketing untruths addressed.
There are simply verifiable facts, such as sensor resolution and omitted by marketing inventions like "FullHD" is replaced, knowing that the consumer has little opportunity to really control. He believes the product he has had the best.
And now we are in the codecs ... clear, we can of course, a less mediocre Resolutionmit a codec to a picture processing and say: "it is sufficient for normal petrol consumers."
So why do not we treat synonymous Otto normal consumer a decent picture, of which he believes it to have?
And the higher the Picture s.das requirements are, the higher the quality of the codec, in order still to be feasible to monitor conditions to bring.
And the demands are rising dramatically .... denk mal s.1080p50. This is a multiplication of what is today as compared to HDV is recorded.
aside from that MPEG2 in the regions is no longer defined.
Think s.all those who perhaps synonymous the film look with the REDS, Scarlet or synonymous to CanonD5 want .... because no one speaks any more about MPEG2. So what is it, anyway s.etwas medium is no longer the glorious future of television will be. The IRT (together with the BR) is currently examining the framework conditions, MPEG4H264 synonymous terrestrial television synonymous for SD use.
So why do you want s.einem old codec hold. For the companies to understand ... The longer I am an old product can sell the greater will be my profit and as long as I think buyers who want to have nothing better, every company would be nice stupid, they do not want to sell, they ask ...
But just as is the strength of the Conumenten. Steve Jobs has accused the industry, they would be the possibilities of the HD display woefully neglected. That's true ...
So if you now ask whether the Consument sees a difference, I can only say: On the estimation capabilities of the Consumenten not. I have many years of television and made the call in the cue was full rather quickly, if image quality were not correct. I have high respect for the abilities of "normal" viewer.
And such conclusions as Meggen they may be made to sound plausible, but unfortunately just wrong ..... and just right is unnecessary, because the tendency one way or the other goes to AVC.
So why not with a better codec deal synonymous if he is still not as comfortable to handle.
Sometime you have to be so or so and thus employ the longer I wait, the more I am next back later with my understanding, and our eyes shut to MPEG2 on the descending branch can be found, brings not really synonymous next.

@ Meggen
I suspect that the encoder used is lousy, maybe so will the video of HD after SD converted, who knows. But I do not believe that this user a carefully executed conversion of MPEG4 MPEG2 as so dramatically would feel. I tend not to the users to appreciate and do think that it's synonymous Consumenten a possible error-free conversion performed. And why should the differences did not set off as its serious.
I see every day many different qualities (admittedly from a different league) but the differences are drastic.
Perhaps this was so synonymous your conversion or reproduction of AVC is not correct? White man's?
Antwort von Meggs:
And why should the differences did not set off as its serious.
Severe or not is relative. What one perceives as a grave, the other feels as hardly noticeable. I think someone who is the picture as an excellent felt SD9, belongs more to the latter group. I synonymous - I have to admit. I feel the quality of losses when converting MPEG4 MPEG2 with a reasonable rate is not so crass.
I think not synonymous, that the transformation he has made mistakes. Perhaps there is only one button to press. Each case will be ¬ 500 for a HD camcorder is not accompanied by high quality MPEG encoder. After he writes that the transformation has taken place, in order to burn a DVD, I suspect that in fact after SD has been converted. The course, he feels as serious. Particularly if he perhaps a PAL DVD and then burned on a bad scale HD Television has viewed.
But as I said: These are of course only conjecture.
Antwort von WoWu:
True, it can now only speculate, but I found his observations as perfectly understands ... and as you see, quite synonymous objectify.
But let's just stand there.
His input questions are hopefully answered satisfactorily.
