KDVD or DivX
Hi guys. First post on the forum, but I've been here for quite a while, and I've exchanged some pms with many here before i would post.
Thanks kwag for a great site, and for answering my stupid questions when i was starting here. Thanks to Rui too :D just to make sure i wouldn't make an ass out of myself :lol: I have a question, which seems to be a little touchy at vcehelp.com On a thread here www.videohelp.com/forum/viewtopic.php?t=223388 they claim that Xvid, Divx is a better alternative to kvcd,kdvd. Well, to my eyes, and after many tests i have made, i can't really see a difference between a well done kdvd and a divx! I have made many tests with mpeg2, and when i use the notch tables, the results are as equal as a divx. anyone could confirm this? Thanks. |
Hehehe - one thing I've noticed about that forum is they're VERY fascist in their nature. It's their way or the highway..., and their way is to bag k-type video (kvcd ksvcd kdvd).

Here are some screenshots and encodes I just did, just to shut them up :lol:, where anyone can clearly see that KDVD is just as good a DivX/XviD, but KDVD will play on every standalone DVD player (underlined for our friends at vcdhelp :!: ), but DivX/XviD will play on a handfull of standalone players. Here's a high speed capture of an MPEG-2 KDVD (done with TMPEG): http://www.digitalfaq.com/archives/i...2004/06/17.png Here's the same scene captured from the XviD: http://www.digitalfaq.com/archives/i...2004/06/18.png And here's a lower motion on front, some motion on background MPEG-2 KDVD: http://www.digitalfaq.com/archives/i...2004/06/19.png And the same scene with XviD: http://www.digitalfaq.com/archives/i...2004/06/20.png The results are pretty clear to me ;) I can reproduce the same thing on low bitrates too, so XviD/DivX is out of the question for me. As far as I can tell from that thread at vcdhelp, most people there keep insisting that our stuff is not compatible. That's correct with MPEG-1 KVCDs, but they are MISERABLY WRONG when we use all of our techniques applied to KSVCDs and KDVDs. They just seem that don't want to accept those facts :roll: Here are the sample files, so anyone can playback and compare, and "see the light" :!: :lol: http://www.kvcd.net/cowboys.avi [3776KB] http://www.kvcd.net/cowboys.m2v [3869KB] Both files are almost the same size, but I did the XviD as close as possible to the MPEG-2 file, using 1-pass quality based encoding set to 96 :!: I'd say that's a pretty damn high quality value for an MPEG-4. The average bitrate for the KDVD is only 2,773KB, which is very low for that kind of action scene. Also NO FILTERS WERE USED, and I said that in upper case, because it seems some of our friends at that site insist that we use "heavy filtering", and that's why we get small file sizes. Well, this proves (again) that they are plain wrong ;) -kwag |
Well that explains it all!
Who needs a divx player anyways :lol: Thanks! |
I think I'm going to have some fun with these people :D
I just read that thread where vitualis says: "For example, try making video clips for Pocket PCs at 320x240. You can get away with reasonable quality video with DivX at around 200-300 kbit/s depending on the video quality. Impossible with MPEG-1 or MPEG-2." Well, because I don't post there as I quit that site a very long time ago because of their stupidities, I'll now prove (once again, as I have done before over and over again :!: ) that they need a reality check :lol: Here's your PocketPC version of KVCD MPEG-1 at average bitrate of 293Kbps, clearly (in overall quality) beating the CRAP out of XviD :!: MPEG-1 KVCD "Notch" matrix: http://www.digitalfaq.com/archives/i...2004/06/21.png XviD: http://www.digitalfaq.com/archives/i...2004/06/22.png MPEG-1 KVCD "Notch" matrix: http://www.digitalfaq.com/archives/i...2004/06/23.png XviD: http://www.digitalfaq.com/archives/i...2004/06/24.png They will probably say that this picture is "subjective", which seems one of their favorite words :lol: MPEG-1 KVCD "Notch" matrix, low action: http://www.digitalfaq.com/archives/i...2004/06/25.png XviD, low action: http://www.digitalfaq.com/archives/i...2004/06/26.png Here's another "subjective" picture, where you can't even see the eyes :rotf: That's what you get on MPEG-4 object based encodings ;) Zoom in on those two previous images, at least 5X, and you'll clearly see the detail loss on the XviD, while the MPEG-1 version is clearly a sharper image with more details vieweable. Pay particular attention to the face :!: Samples here, and AGAIN: NO FILTERS USED : http://www.kvcd.net/cowboys-320x240.m1v http://www.kvcd.net/cowboys-320x240.avi These clips are meant to be viewed on a Pocket PC sized screen, or on WMP or VideoLan client without resizing. Remember that the resolution is very low, and the bitrate is extremely low. Now, my question is: What will be their next excuse :roll: -kwag |
after see the pictures and 2 years comparing the results(day after day)....
"i don't know why" :roll: ..... my preference is KVCD! you know the reason ? :rotf: sincere opinion: i have lots of wonderfull programs(canopus edius,CCE,vegas,adobe premiere,ulead video studio...toys like that) and they give me good results BUT 2 hours (or more) in only one cdr 700 MB with quality in audio and video :arrow: only KVCD can give me .....the remainders need more space to give seamless quality...more space means---> "MORE" space, clear? :wink: but divx?!?!....oh c'mon! :roll: all that hard job to see only in pc or(and maybe) in some dvdplayers!?!? like i wrote is only my opinion but i can proove and feel what i get. :idea: be smart...do kvcds and forget divx! play with quality in "everywhere" 8) |

This is what i just got when i tried to log in --- '''You have been banned from this forum Please contact the webmaster or board administrator for more information''' So i can't log in anymore at vcdhelp And to tell you the truth, I don't give a flying F**K :!: I guess '''They can't handle the truth''' :lol: :lol: |
Quote:
no matter what they send to you,here you're welcome and the best: you will get better results in your encodes and friendship in kvcd forum! welcome here and stay free! :D |
Thanks jorel :)
I like the atmosphere here much better! And i like results and explanations better than the '''words in the wind''' which is all i got back there :lol: Keep up the good work guys. I'll keep reading more here. I still have a lot to learn. --> kwag, i replied to your pm. thanks! |
Dam Karl i see you have friends all over the place :D first the thread at doom9 and now this one at videohelp.com
I can just imagine the ones that i haven't seen yet Everytime i see these threads i get so mad and want to get in on it but then i realize that i am not all the bright when it comes to video stuff so i just stay out of it but i would like to thank RUI ,he always is in these threads(no matter what forum) sticking up for Karl and KVCD :D |
Hi bigggt :D
Funny thread, isn't it :lol: Some guys there have difficulty seeing "true colors" :lol: It really doesn't matter what you try to say there. It will always be their way. That's why I left that site a Loooooong time ago. 5 years from now, they'll be doing the same things :!: So be it. They loose, we win ;) And when blue laser, HDVD or some other technologies come around, they'll be happy to fit ~30 hours on the media, while we'll be fitting ~100 hours with the same quality on the same media :mrgreen: -kwag |
Their logic is a bit strange, they go on about the format not being compatable with DVD players, even though all my SKVCD's I've made play on three different DVD players (all different makes) with no trouble at all. They tell you to make DIVX, XVID but don't tell you can only watch it on a computer screen or a dedicated DVD player which costs a lot more as well, strange logic indeed. Try to tell them about the great quality of KVCD and they bite your head off. :? :? :?
|
That's why I always send those who ask questions about kvcd / kdvd direct here without more explanations and comments.
Over the years I believe this is the only way to prevent unpleasent discussions that lead to nothing or bad comments like " they're VERY fascist". (And as you probably already noticed pacheco, I already accused for "anti americanism" at the same post, just because I tried to keep the distances between you and lordsmurf...) Keep what you are doing here, and I hope you never loose your enthusiasm about this hobby. Have Fun |

So for me, the choice is: 1) You buy a DivX player if you can, spend a lot of money and be careful to encode the way your player supports. 2) You buy a cheap DVD player, already knowing that it supports all KVCD resolutions because you tested in the store. And if own a DVD burner, then... You can go KDVD and not worry about any compatibility problems, fitting a lot of footage in a DVD Disc just like you would do with DivX/Xvid... But being able to play in every DVD player. I was reading the videohelp.com thread and refrained myself from making any posts because I knew it won't get anywhere. In that point I agree with SatStorm, it's better to direct people asking about KVCD here, so they can learn the full method. People there seems to only have "stick to the standard and old-faishoned ways" in their mind and they can't get beyond this nor let the others try. This is something that has been proved in that thread, with a few exceptions of course. |

I read the thread and, guess what, Dialhot found the exact way of describing the activity at VCDHelp (although I don't know if the expression translates into english) !! |
Hello SatStorm,
I didn't know you were registered here at KVCD as well. Then let me tell you that I am very pleased to see you around. Also I guess I need to make one thing straight: not everybody at vcdhelp or Doom9 acts like LordSmurf. There are plenty of nice people around those forums too, and you SatStorm, I include in this last category. Again what I would like to see from LS or anybody there is something like: "KVCD? Well either I don't know that much about it or it doesn't give nice-enough results, but you can dig some more info at their KVCD.net forum". That way I wouldn't feel so pi**ed about it. Just imagine if someone would come here asking info on XviD and Phil would just say: "Pure crap. Stick to KVCD/KDVD!". (sorry Phil :oops: ) Don't you think that the poor guy would buy it immediatly, coming from Phil with such a big post counter. But in the end Phil could be misleading the guy just because he wouldn't know how to configure XviD codec properly (and we know he DOES know :) ). I just think that's not fair, period. And I'll keep sending newbies back to videohelp forum, because it's one of the best (if not THE best) forums to learn from scratch. Then if they feel like staying there permanently, fine, it's their call! If they choose to come back and give K techniques a try, great, I'll try to give them the best help as possible. This forum - www.kvcd.net/forum - was built by Karl, but nowadays with so many users, it's actually OUR forum! So back at videohelp I was not only standing by Karl and Pacheco (and a few other nice guys). I was also standing by the friendship that I sense everytime I come here. And that I could never sense at anywhere else. Maybe that's why others will never know that there is K techniques, and that is a big shame! Imagine the world without MacOS/*nix/OS2/BSD... Microsoft would rule and we would probably still be running Win 3.0 on top of MS-DOS 4.0 (that's probably 10 years ago, right?). Cheers |

I am 5 1/2 years in this scene, so I'm registered almost anywhere exciting things happens.
And I might not agree with anything you talking / present here, but I can see and feel the enthusiasm you have. And that's enough for me, so to visit once a week this forum and read the various posts. And that's why also, I said "a friendly and very active community". Because I know you from distance. Personally, I'm not into CD based solutions and I don't focus anymore on the encoding part of this hobby. I manage to have the results that please me "my way", so this thing is concluded for me (interlace mpeg 2 and how to encode it). I basicly focus on filtering analogue sources I capture from various media (from old VHS tapes to HDTV DVB transmissions) and learn in deep that part, without the use of avisynth (which I don't like at all, even if I respect it and realise the need of it). About the forums: There are entry and advance forums, also forums based on cutting edge or average things. I won't determine what this or that forum is, neither which is better. I only say that each forum gathers the type of the users that represents. Here, you are very determined on what you are try to do and succeed. Those posting here, test and explore specific things. Don't expect the same attitude and the same enthusiasm you have here about kvcd/ kdvd elsewhere. Neither the same reaction. I know myself about it (just read the responses I had when I publish about CVD, 2 years ago ... ) Anyway, personally, I point direct to this place here, when someone ask information about kvcd / kdvd. And I don't rise a critic about it. This is, I believe, the best solution And as I said, Keep what you are doing here, and I hope you never loose your enthusiasm about this hobby. |
Quote:
We can all live with that, I'm sure. More, that's basically what I've been saying for a lot of posts there already. Quote:
We just expect fair comparisons with other methods and people to be elegant enough to technically admit that KDVD techniques ARE NOT tmpgenc templates, as they work with the majority of soft. encoders out there, and that those are 100% DVD compliant, period. If they say otherwise, please document/post why they say it's the other way around. Anyway they could come here once in a while even if they don't like K techniques as they may come to learn something, as I do when browsing D9/vcdhelp. Cheers |
I think that whole "war" is ONLY based on philosophics and also who wants to follow which philosophic (the nice word "apostels"). :lol:
So I dont know WHAT THE HELL is that all about there? Makes no sense to put energies/explanations into such subjects which will everytime rise a new (IMHO). :?: :wink: |
Quote:
Because if I find a site that I don't aggree with, it clearly means I don't like it, so I just won't visit it :!: Quote:
Hmm.. Interesting attitude :roll: Quote:
Quote:
We also do DVD, captures DVB and many other things. Quote:
Quote:
Our attitude is the same as most that try to push limits and extend standards. We are not the only ones that do that. That's what separates this kind of site from other standard sites, which will never have that spirit. Quote:
Sorry SatsTorm, I just had to laugh my ass off, because I know damn well what you constantly reply at vcdhelp. I don't post there anymore, but I do read once in a while, and I search for "kvcd' there just to see what kinds of comments people are saying. You are one of the worse detractors, and I'll make it public here, postiing several of your comments here right now: Quote:
Quote:
Which is never claimed KVCD to be a "Standard", but you keep trying to put that word on my mouth ALL the time. My answer was also clearly posted on that last thread. And then your BEST post, which I never replied, because I had signed out of that site prior to this beautiful post, which I will now reply HERE :!: Quote:

A resolution is a resolution. Just like an audio frequency is an audio frequency, and anyone can generate any audio frequency or even a radio frequency. Sure, RF is allocated and assigned (in the states) by the FCC. But let's not go off topic here. Quote:

The MPEG-LA has the patents on MPEG-2, and they can do whatever they want. Quote:
As to our propietary and registered matrix, it's our leverage over other matrixes and even over the standard. The MPEG Group clearly defined that part for the benefit of any manufacturer, both on MPEG-1 and MPEG-2. Quote:
So you see, in reality, anyone who owns TMPEG, CCE, MCE, has already paid their share to the MPEG-LA group, because when you bought the product, you are paying a small portion that goes to royalties. But you see, if a commercial company wants to integrate our matrix, they have to talk to us, because we hold the rights on our matrix. And that, my friend, I can take to the bank ;) Quote:
Quote:
They improved on MPEG-1, just like we improved on MPEG-1 and MPEG-2. Quote:
What is the problem :?: :lol: Quote:
But the same way, if ANY commercial company want's to oue our matrix, either on MPEG-1, the obsolete MPEG 1.5 or MPEG-2, the must pay US royalties, and that's a fact ;) Quote:
Why do you think we were able to register it :?: Because it IS different, and no other company EVER came up with a pattern that matched ours. Not for DVD, VCD, SVCD DVB or whatever. Quote:
You pay royalties on "encoders". Not on decoders. (under most circumstances) Quote:
KVCD is not a ripoff of any other work, and the matrix is my original work, not based on any other existing matrix. Period. Quote:

For my mind, someone who won't accept that the internet is worldwide, and american (or any country) rules cannot be forced onto the world is dictatorial and fascist. Excellent summation there, Kwag - I'd already read most of those posts.. LOL |
excuse me but .....SatStorm seems a nice guy! :wink:
i feel "education" and his words, of course is an great person! @ all we all have opinions.... and differents opinions(when exist) it not means enemys, right? like i always write(or try to write) english language loose some feelings in the phrases! translations and interpretations always loose feelings! :( now @ all and @ nobody...about standards: Henry Ford build the "T" model as standard. what i do with my ferrari? :? ntsc-m b&w tv is standard: what i do with my pal color tv? :? and the very complicated point: if you're not the oldest son in your family,can your parents think that you're not "standard" ? :lol: :rotf: standards are "labels" for conventional parameters that can be changed.... for better! :wink: |
I think that was a bit harsh Kwaq. I remember when you were
a newbie at videohelp.com and I'm sure I could scan through your comments and pick up bits and pieces to criticize. While you may despise the site, vcdhelp was part of the impetus behind your 'format' and the establishment of this forum. Hope you don't mind if I stick around and check things out as I did not know you were still around. KDVD sounds interesting. |

It was usually busy posting answers :) ( or getting flamed for the things I was trying to do :roll: ) But hey, it's my nature :!: Do you know what is the nature of Radio Amateur (HAM) operators (I'm one) :?: The main goal is experimentation, pushing standards, and making new standards and other techniques :D This is what we do: http://www.arrl.org/hamradio.html One definition is this: # Promotion and enhancement of the Amateur Radio Service as a voluntary noncommercial public communications service. # Continual advancement of the art of radio communication. # Expansion of the reservoir of trained radio operators and electronic experts. # Enhancement of international goodwill at the grass roots level. References here: http://www.wordiq.com/definition/Amateur_radio To give you an example, and to tell you that I am a radio freak, because in 1989 I set up the first 1.3Ghz Amateur Radio repeater here in P.R. :D Back at that time, everyone else was using either 144Mhz, 220Mhz and 440Mhz repeaters, and we (3 crazy ham operators) were having fun talking and doing data communication tests (X25 packet radio) at 1.3Ghz band :lol: So that's why I don't settle for "Standards", if they can be improved and modified for the benefit of everyone. Maybe some people can now see the relationship of this to KVCD :) Quote:

Kwag, we really have a communication problem here...
Anyway, here is the whole sentence about me an Turks: ------------------------------------------- Filotimo: "It contains a sense of honor, obligation, self-respect, and teamwork. Literally, it means love of honor" This is close, but as you see, you can't exactly understand it! The example given is not exactly accurate. You can use "filotimo" to "defend your country", but you also use "filotimo" to help your kids even if they are lazy 50 year old bastards, and you are 90 with one foot in grave!!!! Other example: We don't like our neighbour Turks. In the matter of fact, most of us hate them. We almost daily ready for war with them. Then, an earth strike appears and Turks had a dissaster. Because we have filotimo, we run first to help them. Filotimo is one of those things you can't understand when you are not Greek. In the matter of fact, filotimo is what make us and keep us Greeks! ---------------------------- This is a historical fact: I was in the army back in 1996, when we had a incident with Turks, close to war. 5 years later, they had an earthquick with plenty victims. There were our enemies right? Well, we where the first run to help them!!! Just ask them... Anyway, english is not my native language and mediterenian is my temper. You quote words. I talking about meanings. About the DVB and your ideas Sorry Kwag, but: I post and I was waiting for an answer. And I didn't state anything posting here. I just tried to calm things out. You bring all those things here To tell you the true, you don't play fair. And I wasn't prepare for this. The who we are shows. From our posts, our attitude, our expressions. Language is a barrier, but the meaning always exist. Anyway, if you wish to seperate so hard ways, no problem with me. And, don't keep telling us who you are. You are Kwag, I'm SatStorm and this is internet. If you don't seperate internet from real life, then you are a very advance person... About the attacks: I never attacked to you. Others yes, but not me. But, here, you obvious attacked to me. Just like you was waiting all those years to show up and do your stuff I mean, if you wish to stand for yourself, do it with those who really attack you. Not me... Anyway, sorry again for posting at your forum, because I feel that you don't want me here. Sorry again. |
Esto lo diré en castellano, espero me comprendan y que no quiten este post, más bien si a alguien le molesta, que lo traduzca.
Discusiones así (a otro nivel, por supuesto), por tonterías, son las que finalmente desatan guerras, estoy seguro. Si bien en el pasado se pueden haber dicho cosas, es propio de ser humanos el poder cambiar de idea o no, pero si de actitud. Yo veo aqui que SatStorm mantiene una actitud muy humilde, cosa que no puedo decir de otros inclusive en este mismo foro, y que se han traido cosas del pasado para agraviarlo. No merece la pena este tipo de discusión. A alguien le gusta más KVCD, adelante. Si es lo contrario, adelante. No han dicho aqui en varias oportunidades que lo importante es la amistad. O es que sólo son palabras? |
I completely agree with you Pro friend, but we need to realise that SatStorm is a Moderator @ vcdhelp.
He has the responsability! Remember that post from you when you were cheering VMesquita for his hard work with MencodeMe? Remember that you used some very "hard slang" Portuguese Google-translation words to show your feelings? That was the 1st time I realised that I was a Moderator here @ KVCD. And I remember I was going nuts about that post. I knew I had to do something. You weren't online and neither was Karl so there was no point in PMing you or him. And I was forced to edit your post against my own willing in your back. For some time I was furious with myself. That was the last thing I would want to happen! Hopefully you didn't get p**sed about it :) So you see SatStorm has the responsability and he knows it! He may well be a very nice Greek pal but he has to act when he sees something wrong. But instead of doing it all the time with some vcdhelp veterans he does it with Pacheco, a nice cool guy that apparently is also registered for quite some time there but that has a very low post count there! And what did I see Pacheco doing over there? Not much more than I did: claim for some respect between forums and forum members and asking for some fairness from them when we post that instead of saying "crap, period" they could say "not very interesting to me, but hey they have their forum and you may pick up some more info there". In the end, I think SatStorm all alone can't do much over there so he has to go with the flow otherwise they just ban him too, but that's only IMHO. On my side of it, I don't have a problem with SatStorm, so everything is cool, but I think he may have a problem between him and his conscience. Cheers everybody |
hey Correia,
:idea: maybe SatStorm will strike himself in his forum! :lol: but he seems a cool guy ! |
@ Prodater64
Bravo, puesto bien :) @ Kwag Thanks. I did not ask many questions either because like you I guess I found it quicker and more 'reliable' to work things out for myself. Yes I have an idea about the nature of ham's. You mean AX25? Very nice. But how does repeating error corrective RF in digital packets state your case? Anyway I thought X25 was a standard from the 60ies? Sure, repeating AX25 packet radio in '89 at 1Ghz is cutting edge but it is not bleeding edge and certainly not new to the world, even though I'm impressed. Your team must have been one of the first ham groups in the world to do this. Still PR is still PR no matter what frequency you squirt, is it not? Any improvement in data casting is due to the spectrum - am I wrong? I think the main problem in your early days is that you originally modified a template (something that many others had also done) and decided to call it a new format. I'm not talking about your current work- just your original efforts. If I improve a tire tread patten, I'm not going to claim to have invented the wheel. I'm not saying you did this, but it was seen as such by some fairly respected people at the time. Hence the unpleasantness I guess. That and perhaps some less than intelligent input from supporters on either side. :) Anyhow, appreciate the welcome especially as I was not one of your supporters in the old days. |

No, actually it was being done worldwide :!: I had a lot of fun doing FTP file transfers from different countries, at 300 baud over HF bands back then :lol: Quote:
BUT because I hold an Extra class license, I can do some things at some frequencies that other HAMs are not allowed. Even experimenting with any data protocol that I may design, over any allocated frequency of my choice. Feels good to be able to do that. Hey, have you ever heard of "Moon Bouncing" :?: Well, right here in Puerto Rico, we have the world's largest Radio Telescope, the Arecibo Observatory http://www.naic.edu/ and HAM radio operators have gathered with special permissions to do moon bounce voice transmissions with other HAMs around the world. And that's really something interesting and exciting :D I know some of the engineers that work there, and the first time they told me that they were using Gallium Arsenide FET cooled down with liquid nitrogen to lower the noise figure in their receiver pre-amp stages, I thought they were crazy :lol: But that was back in 1981, when I was still playing with my Atari 800, and it could't sink in my mind that kind of circuitry. Some things they do there are really out of this world :!: Quote:
Data is data, which is digital, and if you refer to single cast ot multi cast, that has nothing to do with frequency allocation or spectrum. If you refer to allowed "emissions" on a band plan (like FSK, FSK-NRZ, etc.) that's another story. But those are analog formats. Quote:

amatur radio ham so I could be wrong. I remember BBS were using HF for fidonet echos. Hey, have you ever heard of "Moon Bouncing" Sure have. That lump of cheese is little more than a big telstar. I don't think you could FTP from it though. It would be funny if the moon became a data haven. :lol: Quote:

Probably we were :!: Until the damn hurricane "Hugo" hit us in 1988 (if I recall correctly), and took away my two 13DB high gain antennas :lol: Our site (not web site :lol:) was on a 2,000 foot mountain on a commercial communications site (thanks to Motorola, back at that time :cool: ), so we had a very good coverage. But when the hurricane hit us, it was bye bye to the tower and all the antennas it had :lol: And I cried :cry: :cry: Quote:
Imagine the TCP delay :lol: Actually that's a current issue right now for space communications, using TCP/IP :!: The delays are too short (TCP window) to be used on long range communications :D Quote:

about with y/x. 8) I think there was a fourth, a mix of x and y perhaps called frog something? Quote:

lossy even then I'd imagine. SCI FI Authors talk about the hydrogen line for space communications. Know anything about that? Quote:
