Komprimieren mit H.264 / AVC

Compressing with H.264 / AVC



Frage von jules m.:


Hello, I have some videos that I am with the h.264 standard compress wants. I use the SUPER encoder, synonymous as far as everything goes well, I would, however, the absolute optimum s.Qualität raushohlen. Therefore here are some detailed questions, I hope someone can help me because:

1. H.264 or AVC? And which container is suitable for what? Or will the same go up?

2. ffmpeg or MEncoder? 've Honestly no idea what that is.

3. Is it possible, with Variable data rate to compress, or is happening in the auto h.264?

Everything very specific questions, but it would be super, but if I could help somebody else. Thanks already times in advance!

sorry, landed in the wrong forum. habs nochmal "Video Editing" posted

Hello Jules.m

If you are with the Super Encoder already're happy, you should times "right" MPEG4 / H.264 AVC algorithms try because Freeware Softwares actually not really much hergeben and a whole lot since s.Features simply are not included. Nor like VC1 or just DivX ... or other derivatives.
But if it goes ... prime, I think it's better than all male MPEG 2nd

1)
Question H.264 or AVC ... should be the same and is probably a name issue because the entire heist just officially MPEG4 / H.264 AVC.

2)
MEncoder indicates the fact that he had two passes to encode out. DivX uses this name, for example.
FFMpeg I know only as a converter. The whole FFMpeg Project comes from Hungary and is based on algorithms, which in turn are of Russian origin .... But there is probably synonymous codecs that I know of but not enough to say something about them. In any case, it is freeware. But the converter is in any case fairly rudimentary on-line data-level ... laboriously ..

3)
H.264/AVC provides a VBR Rate Control before, but probably of the Encodierfähigkeiten depend ... Beware, if the freeware out there must be done not to the standard and thus must standradkonforme traffic decoder can not read.
(I still have not found freeware, which has offered standartkonforme VBR)

Before You reciprocating and therefore your "good pictures" on transmission systems, of which you would not exactly what they are doing and then only of their decoders can play, I would once closely.
Furthermore, coupling of you so that the general development of MPEG 4 from. So caution synonymous with such exotic (or even) if it cost nothing.
Who saves s.Encoder can just get an inexpensive camera to buy because the algorithm or the implementation of an impact quite substantially from the picture ....

and what would you use?



Antwort von WoWu:

... at least not the free part from the Internet.
There's a whole bunch of good algorithms s.Markt. But a good implementation of MPEG costs money just because a good programmer and just want to experience long synonymous paid (right) and whether this deployment in 90 EUR for an NLE software can be found again is questionable.



Antwort von Gast 0815:

The latter, however, I would oppose it in all previous comparisons was the codec opensource x264 with always in the top group (see eg http://www.compression.ru/video/codec_comparison/mpeg-4_avc_h264_2007_en.html)
What is undoubtedly true that there is no graphical user interface gives the full access to all capabilities of the codec is granted, you have this, use the command line. And it's worth it synonymous hardly something to be programmed, because the codec is under heavy development and therefore the parameters can change very quickly (sometimes weekly). And those who today ausreizen the codec can be synonymous with a client version live ....
I always hear of what "the" standard, what should it be? H264 is just not on any device class is limited, so it can be different from mobile phones to consoles to the PC. Ultimately, "the standard is always of the decoder capabilities depend on the player. And even within a class are quite different "standards":
"The first H.264-capable standalone player (such as Sony's PlayStation Portable, Apple iPod Video and the standalone player KiSS 1600) are also on certain profiles and levels is limited, so not all features of x264 support." (http://de.wikipedia.org/wiki/X264)
Ultimately, it seems to Standalonevideoplayer again as Mpeg4/ASP to run a device with a feature may be that others do not stop and is compatible only a (limited) lower common denominator (and that is why I should not be synonymous in the house, MediaPC with the network connection is simply the better alternative to the capabilities of the codec without artificial restrictions to be fully used!)

Hello Guest 0815

So this is not now. This begins with the open during the container in which things are packed and the hackers for daily bread, for ordinary consumers but rather exotic.
When I speak from the standard, are of course not the F & P's meant by the Internet Streaming on mobile phones to the iPod go in this forum but rather the video section, especially in HD. I had assumed that everyone can even imagine and it needed further explanation None had. Well, obviously can not imagine any.
The thing with the F & P's in the video section also has the advantage that they are up-or. upwards compatible .... This is precisely the advantage of each. But not are not MPEG4 / H.264/AVC programming. Here are some quite substantially different tools and provide, if only for a "paltry" compatibility. This affects synonymous ASP.
And what the tests are concerned, I had been here once on the subject position and that why the tests are not worth the paper are (the file) on which they are made.
To view the details not to repeat: There is no demonstrable and comparable Ausgangebedingungen for each codec created. Therefore, the results are like a piñata. (Please click here for details the search effort)
It remains thus to be ... who with such codecs bypasses should already know what he does. If he wants to achieve good results, and without the use user interface is not shy, you can, with good luck good results, but then mostly on MPEG4 H.264/AVC standard players no longer play.
Certainly a nice playground for amateur programmers ...

Hello now answered my question really is not.
What products would you recommend to a user a good result. Or better asked "WHAT SETS YOU ARE ON" "?



Antwort von castingeurope:

I suppose to convert of satellite HD transport stream with H.264
always of Elecard Converter Studio (239, -). Their "algorithms" are excellent. Unfortunately, the import takes a 9 GB streams around 4 min. When adjusting the presets disappear again 3 min. If the encoder then get off, pass after you press the "GO" button again 2 min. An encoder for people with patience. On the fast times the parameters for the test change is nich. That takes time. This is a 90minüter in HDTV Resolutionauf a C2D 2.66GHz ever finished in 5 hours.
The x264 delivers synonymous Freeware is a very good result, but is much more cumbersome (Avisynth Matroskasplitter + + install FFDShow and various other tools and a lot of time for training required). Works very thoroughly ... laaaangsaaaam but only 1-2.5 fps. This may be synonymous, but over the exactly the MB file size can be determined. Would you really do? zum Bild

WHAT SETS YOU ARE AN


We are in the fortunate position, mostly with the hardware it can, of course synonymous with algorithms drinsitzen.
We set WAS of Quantel synonymous but the SR-HD Cluster Board of MC A.
Thus, we have all the best experiences and therefore I would be MainConcept algorithms tend. For the DVD Authoring seem to me to CyberLink products, the best qualities to generate.
I am now no other products deklassieren. Unlike testers that an objective you must employ Comparison (t) s, we just need a product that our (subjective) requirements.
DICAS The algorithm we have not even tried, but recently things that have surprised us.



Antwort von castingeurope:

oh, sorry ... had quite overlooked that he explicitly asked YOU ...
I allow myself to believe that someone of the freeware SUPER converter uses
rather s.eine software solution to its concern thought ...
I do not think he specialized hardware with an infidel money in the H.264 transfer stuck wants.
This is probably just what he can write, let's see ...



Antwort von WoWu:

Of this I am not synonymous ... synonymous and it recommended no hardware .. because we have an opinion ...

You mean h264AVC from SD DVDs burned?
Which product of CyberLink exactly do you mean, yes to sell a lot, especially a lot of real down.

this board is not yet in the development phase?
