Infoseite // MPEG2 stream subsequently cutter?



Frage von Alex.A:


Hello,

I have the following problem: a DVD on a piece of post rausgeschnitten be purely and another cut.

I have now managed to the extent that I M2V stream of the DVD and these have now with MPEG VIDEO WIZARD could edit, but there's a setting for export only the possibility that the stream is calculated from scratch, but exactly what I want to avoid.

Now the question s.euch exists such a tool at all with the I-stream mpg edit (cut) and can subsequently be exported without the recalculation of the stream?

For any help many thanks

edit mpeg-2 "in Google and you'll find at least 25 programs that can do.

Oh man, this board is really slow to ma ******, instead of just to help, there are no answers to it. If one of his knowledge not want to share with others, then please no postings!

I asked not for a tool that can cut mpeg (MPEG VIDEO WIZARD kanns synonymous), but one which supports synonymous export without recalculation!

Antwort von WaldemarSchuh:

Ulead, Pinnacle, Cyberlink, for example.

Antwort von PowerMac:

I think some users of the forum are increasingly becoming a ******, because it does not strain the brain. Researching three minutes and you have 25 programs, the native MPEG-2 can be cut. Match Point 3 is a huge experience for MPEG-averaged Slashcam. And you have the audacity to aufzuregen you?

List of times now but the 25 times on Programs (MPEG2 cut plus smart rendering )..., Loss immediately ...

I bet you're a braggart and bring you no list with 25 programs together ...

Any program that really cuts MPEG2 (not just MPEG2 imported and exported again afterwards), gives the result without recalculation from. This can be seen that the cut-in s.einem only I-frame can be set (for all other things would need to recalculate).
However, it can assume different shapes MPEG2 (program stream, elementary streams) and in various containers stuck (vob, mpg).
Most working natively MPEG2 editing programs require Elemetary streams. (ie a m2v file for the Picture and a mpa, mp2, ac3 or wav file for the sound). Therefore, you must first demux the DVD (Picture and Sound disconnect), then cut and subsequently re muxen.

Proposals (all freeware):
1) demuxer with ProjectX or PVAstrumento
2) Cut with MPEG2Schnitt or Cuttermaran
3) + Muxen authors with IfoEdit or GUI_DVDauthor

Antwort von Alex.A:

I have it now with Ulead Video Studio tries, all changes performed s.m2v stream and try to export ... However, I have the feeling dassdas program re-encodes the stream as it runs in real time (video is running in the preview), as an export setting, I have taken "the same settings such as: 1 clip (in this case is the first clip from the m2v stream. ..

Is this really so? In my opinion it should go much faster but is not it?

Antwort von WoWu:

Hi Alex

that is so synonymous ... if you are committed once the prerequisites s.einen MPEG2 bitstream, particularly with regard to the timing mechanism made, you will notice that the output files are always re-encoded. (Whether in the background or in real time, it depends of Progr.zu App) There are only a patented method of Snell + Willcox, based on the original matrices and vector descriptions back the MOLE method, developed of the BBC, Snell & Wilcox, CSELT , INESC, EPFL, ENST and the Frauenhofer Institute under the "umbrella" of the SMPTE.
CyberLink and MainConcept could doubt that it is smart rendering a similar procedure, but rather a marketing name synonymous not removed.
Your observation that is obvious to take.

Antwort von Gast 0815:

@ Wolfgang,

the procedure but is likely only to eventually neuzuberechnende areas, if not s.Keyframes cut was otherwise sufficient simple binary yes ADITION of cuts, as bit rate, etc. so directly encoded in the stream are available, these areas would otherwise be quite normal neucodiert halt. Or do I interpret this completely wrong?

Antwort von Alex.A:

hmmm .. nu but I am completely aufm hose ...

as of some users has been praised, there are a lot of tools which can be (given what was even with 25) ... say what is not synonymous change was not re-encode, but only what has been changed (but even I have previously referred to m2v encoded and then cut), so I expect only the joining of the entire project to a stream without re-encode everything to be because of quality loss.

Hope someone can enlighten me.

Gruss
Alex

And I had even rausgesucht links.

Now there are so many pictures but heavily compressed. I change the statement a bit:
Anyone who has ever tried has 2-3 GB of data to copy the synonymous knows how long that lasts.

@ Guest 0815
Quote: Or do I interpret this completely wrong? No, absolutely correct. Only when the cuts are too different, I would re-encode.

Antwort von Alex.A:

Hello Martin,

I have already given both of you for cutting tools investigated, and the problem is that there is no crossfades (soft crossfading would be enough) are possible.

Therefore, the search for me, not yet finished.

PS: MPEG2Schnitt is a super tool. The orientation sI-frames is class, but as I said I need a crossfade where possible.

@ Alex

But then you'll get a small NLE does not come around.

Quote: If everything is done digitally, and then everything comes back to the same place.

Just not always when Neucodierung it depends on how good the encoder is of course synonymous and, especially, how good your source material is. Because it is MPEG, but only estimating tools that are naturally present s.dem guided imagery, the results are quite different from ... just better, it can not be.
Tests have at critical picture material, the motion estimation "exhausted" has shown that in the source material are artifacts per SR significantly increased and changed.
Picture-In good starting material for several generations, no significant changes.
The results vary depending on course of a few conditions (Render Render time or depth, real-time requirements, bit rate limitation, etc.)

@ Gast0815
I assume that the average s.der body should be so that the subsequent decoder that is not "stumble" and that a continuous data stream with full GOPs will be created.
This requires a few things not only vote but s.den interfaces synonymous within the streams. This refers to the adjustment of salaries of frames, on the Sound, on the timing and more. Also, there is indeed such a procedure. As long as I remain in the system can I tell my decoder each anomaly, if the bitstream but leaves the system, I have no more to the subsequent chain decoder him any irregularities in the stream to signal. There must be a closed, self-consistent data are produced.
The simplest of all and manageable method, which still runs in real time, is now trying the Encoding and as long as the raw material is high, this is synonymous imperceptibly.

@ WoWu

Therefore, it is so synonymous demuxt, video and audio individually cut, the time code in the GOP re-written, the bit rate in the first header of the file adapted, "orphan" B-frames and removed again gemuxt (or a DVD created equal). Recalculated Video - Audio and parts should be the original course as close as possible (is synonymous for the bitrate of the video parts). For me it is not yet cause problems with these DVDs come.
Of course this is nothing for the professional sector. DVDs to be sold must be first-class course and run on each player.

Antwort von Alex.A:

Sorry that I crossfade with the beginning of s.erwähnt not have.

My NLE is Adobe Premiere CS3, it would go so synonymous? If yes, what settings should I use for export?

I need to have the ability, all carried out at a friend with Canopus Edius 4th I would obviously prefer Adobe Premiere ... wenns but that should not go, tips for settings in Edius I would also make life easier;)

Thanks in advance

Go, it is much more likely that their technology would not disclose. We had already discussed many times - just because someone protects its trade secrets, one can not assume that the technology behind it lies and deceit just had.

I can only tell you that Edius in the mpeg-cut is quite good, and the smartrendern synonymous for SD resolution skills is expected. In CS3, I know it is too little.

Antwort von WoWu:

Dear Wolfgang ..
.. as if there were to MPEG2 are any secrets to keep each and almost every NLE Manufacturer Marketing operates with such terms.
Times I'm curious what the next words will be invented.
As I have already companies like Apple prefer that the child at least call a spade a spade ... or do you mean, which could not be "smart rendering"?.
Ne, ne, it is and remains Bauernfängerei ...

Antwort von wolfgang:

Yeah, I hear the message well, but in daily practice, we observe something quite different. And I even relatively no preference, as a company is called - but the thing works perfectly.
