    I've problem to convert AVI files captured using my KWorld MPEG TV
    card (model KW-TV878-DIM with CONEXANT fusion 878A chipset) with every
    software I've tried. All of couldn't check out what codec being used
    by the capturing software that came with this card's CD. I've asked
    kworld many times of this question but they have no reply.

    There is a freeware program called "gspot" that will tell you what
    codec is expected

    It would probably help to specify what software you are using.

    The KWorld hardware is a basic Fusion 878A based card, and actually
    produces 4:2:2 YUV raw video. It is your software which does any

    gspot downloaded but I don't know how to use it to convert avi file to
    other format file.

    Below is information reported as I use gspot (v2.21) to view the AVI

    File -> Stat field: File length correct (explanation is 'This is a
    valid AFI file ...')

    Video Codec box showed below info:

    4CC: I420/YV12
    Name: RAW I420
    Stat: Codec NOT Installed

    Stream Type and A/V Interleave box showed below info:

    Type: OpenDML AVI
    MRR: n.s.
    I/L: Not supported.

    Audio box showed below info:

    Stream 1 codec

    Name: PCM Audio
    Stat: PCM: No Codec Required

    As I selected 'Export' from Main menu 'Options', a window popped up
    showing me some export setup. Initially options like 'export format' &
    'File setup' are unavailable until I selected 'Enable Exporting'
    checkbox. But even then, I couldn't figure out where could I instruct
    the software to do video format conversion from AVI file to other

    I opened the file ExportFormat.txt in program directory of gspot and
    it showed below content.

    Could I use this file to instruct gspot to do the conversion for me ?
    Or gspot is not a A/V file format converting software ?

    In general the trick is to try to find a codec that supports the AVI
    file you have, not to convert the AVI

    You can find many freeware codecs in the tools section on
    dvdrhelp.com. You can probably convert the AVI, if that's what you
    really want, with VirtualDub

    It is purely an information tool. It has no conversion capabilities.
    I420 and YV12 are raw formats that don't have codecs. Unfortunately,
    some software doesn't know how to handle them. I'd suggest VirtualDub

    You mean there's no way to convert the AVI file to other format even
    if I can find the codec ?

    If you have the codec, you can reencode to another form.

    I followed LeeBear's "DiVX (AVI) to (S)VCD using DVD2SVCD" guide
    (http://www.dvdrhelp.com/forum/userguides/111846.php) and used
    VirtualDub & DVD2SVCD to do the conversion.

    Unfortunately, I was still unable to convert my AVI files.

    To make my problem's description simple, I uploaded my computer screen
    at http://www.geocities.com/emil_lamathk/index.html for reference.

    I followed "step 1) Preparing the AVI files". My AVI files don't have
    multiple segments.

    See avi2vcd1.gif

    I followed the steps 1)a) through 1)d)

    See avi2vcd2.gif & avi2vcd3.gif

    Step 1)e) not followed as I have no movie split need.

    Step "2) DVD2SVCD.... more then just for DVD's" but because of
    different version, the display is slightly different.

    See avi2vcd4.gif

    Step 2)b) followed but I found the 'Go' button was not highlighted.

    See avi2vcd5.gif

    Although steps following 2)c) followed and other settngs. I still
    couldn't made the 'Go' button mentioned at 2)b) avilable. So I
    couldn't start AVI conversion.

    Later, I found the 'Go' button re-appeared if I closed VirtualDub
    before starting DVD2SVCD. However, I found that even the conversion
    seemed run, the software only converted one .wav only i.e. no vidoe
    conversion took place (I found no .mp2 file in my harddisk after

    I would like to know the reason behind.

    I have never used DVD2SVCD, but it looks like some tried to automate
    running a series of programs, and possibly didn't do it very well.

    Did you save anything at all?

    I am unsure that 25 fps is supported by SVCD, and I am fairly sure
    that 25.065 fps is unsupported. At the very least, you should
    convert to 25 fps exactly. Doing this well requires a bunch
    of steps, but try just Video->Frame Rate... in VirtualDub and
    selecting Change to [___] frames per second and fill in 25.

    Updated, this time I use virtual Dub to scan through all frames,


    results indicate no error. Then I save the file to another name as
    ..avi format and called DVD2SVCD to do the conversion (see screen dumps
    for detailed settings). Basically I used the software's default. The
    software did complained the frame rate (this time 25.004) is not
    supported but it also said it will adjust that. So I go on.

    All automated steps of conversion seemed went on but the application
    windows always stayed at Cinema Craft Encoder SP (see attached image)
    and I need to explicitly close DVD2SVCD.

    Afterwards I checked the directory and found the corresponding .wav &
    ..mp2 file were produced but the .mp2 file was very small (the original
    ..avi file is 24,514KB but the converted .mp2 file is just 141 KB). I
    opened the .mp2 file with windows media player, file opened but
    nothing displayed although the play scroll bar moved. I checked the
    audio .wav file generated and it seemed the content was normal.

    I have no idea why this happened.
