...but, I cannot create the fake.avi window, as output of ffvfw. How can I create this window with fake.avi file, and how do I make then run it?. Sorry if little off thread. |

Now, at VCD resolution, the smaller VBV buffer is not much of a problem, even if it exists. But that is refering to quality. As far as playability on standalones, a small VBV buffes will be an issue on the mayority of players. So you are right. We're talking about two different things :) So more tests have to be done at VCD resolutions, to see if in reality, the bitrate settings do create a correct average bitrate on smaller resolutions.

It's far more advanced that CCE ($$$$$$$$$), MCE($$$) and TMPEG($) I still can't believe some people who insist that MCE is the best encoder. But that's another issue I have on another forum, whuch is giving me headaches trying to explain, because they insist on the superiority of MCE :roll: Quote:
I've been looking for him over at Sourceforge.net, and nothing. E-Mails sent, no reply. I guess we just sit and wait :!: Quote:

Because the tests we made, ffvfw looked better on MPEG-2. But that was on higher resilutions. I still haven't really made any serious tests at 352x240 MPEG-1 with ffvfw. Quote:

It's so full of options, that once we get them operating correctly (we're very close already. I'm positive of that ;) ) we won't look back at other encoder ( for a while :lol: ) Quote:

EDIT: @marcellus I'll repeat docs question: why graphedit instead of VD ? I know some benefits of this, but I want to know yourse. |

@Kwag Thank you for paying attention to what I wrote. Did you tried H.263 quantizing method with your big resolution encodings? Because for me gave the best results. Hydeus pointed out a fluctuating quality problem and I encountered sometime. All I can say about it is that is related to non-intra q matrix (the standard mpeg one) thas has all values set to 16. I think that if it could be possible to make a H.263 encoding with notch matrix that would be a hit in the balls Marcellus |

There's no way we're encoding H.263 with ffvfw with the settings selected, becaue if we were, we couldn't possible play it back :!: H.263 is: One I frame. Just like mpeg1/2. One P frame. Just like mpeg1/2. One PB frame. Represents 2 frames, and based on a previous frame. One B frame. Just like mpeg1/2. One EI frame. A frame having a temporally simultaneous frame which has either the same or smaller frame size. One EP frame. A frame that has 2 references, one previous and one simultaneous. And that's just scratching the surface. So as you can see, no matter if you encode with that setting set to H.263, you're still encoding IBBP structure :) -kwag |

I think that the H.263 thing is misleading (me or you). I didnt believe the encoder makes a H.263 stream (I would be very gratefull if you could explain me what exactly is H.263 because I have no clue :oops: -I know it's something in relation with mpeg 4 but no furher) but uses some "esoteric" method to quantize. And, unless I have to be taken to an eye doctor, it seems to me better looking than mpeg method. :?: The obtained stream is an mpeg2. So, if you didn't try but just thought that could not be played, please give it a try! You might be surprised. As I said, it played on my standalone. |
@Kwag
To be more clear: I am talking about quantizing method and you about GOP structure... I'm going to bed now, here it's 3.45 am... |
Quote:
There's no standalone that will play an H.263 stream. Here are a couple of link to what H.263 is, and btw, H.263 is not related to MPEG-4, although some MPEG-4 CODECS do include H.263. But it's more related and used on low bitrate video conferencing protocols. http://www-mobile.ecs.soton.ac.uk/peter/h263/h263.html http://www.ece.cmu.edu/~ee899/lecture5.pdf -kwag |

But again, DID YOU tried that option? Because all I can understand from your answer is: -you didn't try it because you don' believe will give anything useful and think you would just waste your time OR -you did try it but it's simply encoding the "old" mpeg way with standard mpeg matrix, so that option there is basically doing nothing, just taking up space, so you wasted your time already Please, give me a yes or no answer. Sorry if I become annoying :oops: Marcellus |

At the start, Kwag don't wanted to hear of ffvfw because of all this bugs and shortcomings, but few of as insisted, and finaly he started tests. After few days we gained powerful encoder 8) And we keep going. I'll do some test on H.263 mode, but now I have a litle to litle time for this :roll: I also noticed that VBV problem appear in mux part, and good (or mabe newest) standalones have no problem with that. I do my test on Panasonic NV-VP30, and this baby eats everything ;) |

Here as already posted, so watch the thread ;-)
BUT: As I see he encoded using the std. matrix, IF you use NOTCH there also should be the opportunity to still re-treat that stream in restream using the same matrix while this stream is encoded with. So if possible EVERTIME use in the matrix settings "same as source" if possible. http://www.digitalfaq.com/archives/i...2004/02/10.gif |
I really don't like when people are tlaking behind my back so I have to fix some point there :

I'm personally very hurt by the words "shame". I shouldn't have to justify my act but I quit the codec for lack of time ! Do someone have a problem with that ? I use to be on the forum from 9am to 4am since weeks, helping people, answering their questions and waiting for 30 min more to see if they have other question before to close the thread and I won't talk about the dozens of hours spent on script testing to provide the one that are in the avi->kvcd forum for instance. I bought a DVD writer since 2 month and did have to time to burn only 2 KDVD. I have a TV capture board on my desk since 3 weeks and didn't even had the time to plug it into the PC. I spent 2 nights (yes, two NIGHTS) on ffvfw, and let continue to see defaults than nobody seems to see. I just can afford more to it. I'm sorry to take it personnaly, but I do. |

Second: At least do capture in 352x576! so you capture fieldbased as you never know if a broadcasted Hollywood movie is just speeded up to 25 and fieldshifted ("looks" like interlaced but its telecined) or even a very bad conversation broadcasted from 29.976 to 25 fps! Yep I got that last week when watching the capture from Man in Black! :shock: Because when capturing in 288 height, the second filed will just be discarded which ends up with "stairs" in fine circles etc. |

So I apologize. :oops: |
