    D-clone, u r wrong there!

    yeh, u can convert DIVX to VCD without loss of (much) quality.

    in TMPGENC, when converting to VCD, don't encode straight away. set the VBV Buffer size to 224 and encode

    now watch the quality.

    I converted ALL my DVD rips, and from the web, to VCD using that setting, and woow...people are asking me "is it DVD or SVCD?" But it's actually VCD!

        lol.

        u only lose (if any) 5% of loss of quality, but usually it's none when converting DIVX to VCD, using the setting i just gave ya.

        u were like "NO, U WILL LOSE QUALITY, no shurrup b4 I blow ur head of"

          Before you get in a fight with me too:

          There is no VISUAL quality loss, I agree, it may LOOK like theres no quality loss, but the quality loss is still there, thats alll I'm saying.

            Fight??? HELL NO! I'm ur friend!

            just telling u that there is a way where some quality is not lost.

            ur my bud, we never fight

            we all help each other out

              Are you saying that you can't visually tell the difference between 352x288 and 720*576(480) ?

                wait until I release Techno's Law........

                but for now, ALL I am saying is that, yes, big difference, but when creating a VCD, it tries to take the exact duplicate of the master source

                go on, u try it now KHP, come on........

                don't say that i talk bull.....cause I am 100000% sure this time that this does work, not that I was always lying!

                  For MEANINGFUL information regarding VBV buffer size (see below) and other TMPGEnc settings, go to :



                  "VBV buffer size
                  This value specifies the size of the decoders "Video Buffering Verifier". It represents the amount of coded video data that can be buffered by the decoder. At constant bitrates the buffer allows best use of the MPEG compression techniques. It is filled at a constant rate (that of the video stream) and partially emptied when a frame is decoded. The buffer fills up during sequences that compress well and empties during sequences that do not compress well.

                  Usual values are 40 for producing an MPEG-1 VCD and 112 for an MPEG-2 SVCD. These are the minimum allowed by the specifications, but if you are encoding for a particular player it may have a larger VBV buffer, so these could be increased (producing XVCD or XSVCD discs)."

                  This certainly makes it seem that a setting of 224 for VCDs is no more effective than a setting of 40...

                      To techno

                      This thread was started by "ipanther" (not techno), to whom I was merely providing another source of information.


                      (Your constant argumentative mode, accompanied by "I'm your friend" or "I'm only kidding", wears thin)


                      "go on, test it for urself...u will see."

                      I have absolutely no interest in doing this...

                        So you are magically going to turn apples into oranges ?, excuse me for wanting some proff before I believe such claims. But hey I never claimed to be the world champion of video encoding. So maybe you are right.

                        So you admit that you can see the difference ?, this seems to contradict quite a few of your postings.

                        This is completely untrue, it tries to make a copy that is as close to the original as possible. Makeing a digitally exact copy, using any mpeg compression format is theoretically impossible. Because they all rely on DCT compression.
                        And of course even divx4 encoding at 50kbps, tries to make a copy that is as close to the original as possible, this does not mean that it will succeed.

                        I occasionally point out statements, that are factually incorrect, and I will continue to do so. But I admit that I usually try not to talk to you, because argueing with you is usually completly useless.

                        Just because you believe something to be true, does not make it so. And when you are in clear violation with the laws of nature, I tend to be a bit sceptical.

                          NO KHP, I did not say that I will magically change all of this, this is bull, and u know it clearly. People like you take statements and turn it against them - which is damn right wrong.

                          You are suppose to be helping people, not starting flame wars, like this - AGAIN. it clearly shows that u are starting trouble. I am TALKING from MY experience, not urs, not the next door neighbours - but mine.

                          And NO, I ain't saying I am correct all the time, you think that, NOT ME, I am not that type of person.

                          I have now unsubscribed to this thread because of you KHP, everywhere I go, you have to start something. You are suppose to be helping, not putting people off - like myself

                          GOODBYE, now go bother someone else.

                            You claimed, that you would be able to make a vcd the same quality as the souce DVD. If that is not magic I don't know what it is.

                            Yes, now you are on to something. I turn statements that can be misunderstood. If you would bother to properly qualify your statements, or at the very least respond within the same context as the question beeing asked. This would not be a problem

                            Now you are getting redicules. As I said before, I usually try to avoid talking to you, because I find it completly impossible to have any meaningfull conversation with you.

                            However in this case, you responded to one of my posting, by posting something you knew to be untrue (you have already admitted this). I then called you on that, and for some reason you choose to take this personally.

                            Originally posted by techno

                            Exactly, you talk from your own limited experience. But you almost always fail to make this clear. Just because you think something is good quality, does not mean that every one else will think the same.

                            I strongly believe that everyone should be allowed to make up their own minds about which method to use, without any influence from people who claim to be more experience. For this reason I try very hard to make my postings as objective as possible. Why can't you do the same ?

                            I try very hard to avoid posting any factually incorrect info. And I usually try to make it clear, when I am merly giving voice to my own opinions.
                            If you know of any factually incorrect statements in any of my postings, let me know I will be very happy to correct the problem.

                            Completly incorrect, as I have already explained.

                            And you are supposed to help people too, not mislead them.
                            I'am sorry if I can sometimes seem a bit offensive.

                                This is incorrect. According the the divx5 specs the maximum resolution is 1920x1088, and I think mpeg4 allows for even larger resolutions. Of course, for divx files distributed via the internet, bandwidth and quality considerations restrict the choises. But for DVD Backups I mostly use 704*X.

                                And of course you don't have to use mp3 or wma audio for your divx encoded files, you can use AC3, ogg or even AAC, and many many others of lesser relevance.

                                And Why do you list the audio on DVDs as N/A ?. Every DVD movie I've ever seen had audio. It can be either AC3,DTS or PCM, and maybe a couple of other formats.
