    Hi. I have several FLV to AVI files that are slightly irregular resolutions (320x239 vs. 320 x 240) that the codecs don't like. VirtualDub has a re-size filter, but this doesn't seem to work; possibly because the source file is non-conforming.

    Does anyone know how to correctly size an FLV or AVI file so that a codec will recognize it? All the software I've tried sez the file is corrupt, failure, etc.....

    This res is stopping Virtualdub from opening the fie, or from converting it?

    If it can be opened, use resize and set "Framing Options"
    "letterbox / crop to size" - set it to 320*240.

    The res is preventing VD from opening it. All I get is sound with a black screen. I re-sized the video correctly to 320x240 in Super as I converted from FLV to AVI. VD now recognizes the video and w/ the correct resolution, BUT I still have the same problem when I try to save in VD! It can't process the file with the deinterlace filter (my intention). I know this is because of the coded selection, because I can save the file ok w/o any compression.

    I plan to use VSO's ConvertXtoDVD, so maybe the uncompressed file won't be an issue.....

    Assuming VD opens the file, I don't understand why it wont let
    you recompress, assuming the files are a valid res.
    What output codec are you choosing? Divx/Xvid?
    What error message do you get?

    I'm using the same codec for both the conversion (Super) and compression (Virtual Dub), Divx 5.0/6.0. The error message is "The source format is not acceptable code -2").

    I guess my real issue is the poor quality on a 13" TV. I thought is was an interlacing issue, but could it just be that the source file is an FLV from You Tube? Could that be it?

    Something else for you to try:
    I've downloaded a few youtube FLV's myself, and I handle them
    a little differently from you. It may not work with all, but it's worth
    trying. I use a simple prog - FLVextract. http://moitah.net/
    Drag and drop the flv on the programs window and it extracts the
    content in the same folder as the source.
    Often, the audio is mp3, and the avi has the 4cc flv1, which can be
    decoded by ffdshow (set in ffdshows vfw config).
    Once this is configured, you can use Virtualdub. Try resizing
    and re-encoding with this source.
