  1. Hoping someone can help me.

    I`m compiling a dvd that has about twenty 15 minute mpegs.

    Despite various setbacks, I`ve got to the stage where everything is done and I have burnt a copy for testing.

    In my test copy, in every single file/mpeg the lip synching starts to go wrong about half way through. Speech is generally up to a second ahead or behind the on screen picture.

    I checked the original mpegs and they are 100% fine, so it`s not a source problem.

    I can see in my moviefactory folders the converted files and the speech probs are there, so it seems to be a problem caused by moviefactory during convetring/transcoding.

    Does anyone have any experience with this? i`m at my wits end entirely.

    I have "do not convert compliant mpeg files" ticked and have customised audio format to mpeg. I`m not trying to change movie resolution etc either, just want a direct, no-change burn onto dvd.

    Any help would be much appreciated!!!!!!

  2. Well you are right. MF2 is converting your video or audio.
    what are your specs of the input files, are they all the same. If even one is different, but maybe compliant, it will convert.

  3. Thanks for your help K2

    Might have had a breakthrough. I should have mentioned that each mpeg I`m adding to dvd was made from 3 smaller ones.

    Just loaded one in VirtualDub actually (just got the program) and it mentions more than one warning like this for every file;

    "Anachronistic or discontinuos timestamp found in video stream 0 at byte position XXX (may indicate improper join)"

    Could this be the problem - badly joined files? I checked and in each mpeg/file the first part is normal, and then the other two parts have the problem.

    Is there a better mpg joiner anyone can recommend?


    File info;
    Frame Size 352x240, 29.970fps
    Number of I,P and B frames: 1800/8665/20336
    Audio format 44khz stereo, 224kbps layer 2

    If you need any specific info let me know and I`ll dig it up.

  4. Please provide some more information:

    1. How did you acquire your MPEGs?

    2. What are the precise video/audio properties of the MPEGs as compared to the following properties of MPEGs I routinely edit:

    NTSC drop frame (29.97 fps)
    MPEG files
    24 Bits, 704 x 480, 29.97 fps
    Field Order B
    (DVD-NTSC), 4 : 3
    Video data rate: Variable (Max. 8800 kbps)
    Audio data rate: 256 kbps
    MPEG audio layer 2, 48 KHz, Stereo

    If you have uniform MPEGs , that is not mixed NTSC/FILM
    restream will fix the timestamps. It's easy to try.
    In general this is difficult .

    This sounds like a VCD file.
    Which is not DVD compliant in video or audio.
    Hence it is encoding.

    If you change the audio to 48Khz then you may meet the CIF format, not sure. Wish I knew how to keep MF2 in sync.
    At this point it looks like TMPGenc to re-encode to the correct settings, then author to a DVD.

  7. thanks guys, you`ve given me several ideas here for things to try.

    The source was indeed vcd, and i`ve managed to copy vcd to dvd ok in the past (dat to mpg to dvd).

    I`ve also seen the theory of resampling to 48khz sound too. Think its time i gave that a go.

    Restream looks intimidating but i`ll check it out too.

    I`ll let you know how i get on!

  8. I'm having the same problem! My original source is around 22 minutes long, and the audio appears to be running around 0.5 sec fast after 7.5 mins on the DVD. The "working" mpeg file is not a VCD:

    24 bits 720x480
    8000kbps (const)
    29.970 frames/sec
    LPCM Audio
    48kHz Stereo

    I just built a new machine with the stuff mentioned in my profile. I have installed only SP4, the latest Windows security patches, IE 6 SP1, and the latest drivers for my hardware. The only "software" I've installed is VirusScan, the ATI mmc, and the bundleware that came with my Pioneer
    DVD-RA06USPK4.

    I do not believe this is a problem of mismatched mpeg settings among the various files. Here is why: I burned a +RW disc with only the 22 minute mpeg on it. No other files. Of course I am not converting compliant MPEG files. The settings for the file match the settings for the DVD.

    The original mpeg file does not lose synch when I play it in Ulead Video Studio 7.

    I exported the "working" mpeg file to MovieFactory2. I burned a +RW disc with only the one mpeg file on it. MF2 did not prompt me about rendering the file. I am suspicious of this audio/video multiplexing deal, because that is the only thing it tells me it is doing and it is the only step that takes much time.

    When I play the resulting DVD in the Ulead DVD player (same set of bundleware), the audio is out of synch after 7.5 minutes.

    There's no way this is a CODEC problem...?

    I'm a rookie who does not know how to check the original mpeg file for errors. I am unable to rule out the possibility that there are errors in the "working" mpeg file. It was rather heavily edited in VS7. So, the thinking is that rendering a file in VS won't necessarily produce a "clean" file? I assumed it would.

    I know what happens when you assume...but isn't it reasonable to assume that when rendering an mpeg file with certain settings that the whole thing will be written like it was brand-spankin' new?
