    Hi

    I am trying to convert 4 parts from a DV i filmed from VOB to mov.

    I have done all the parts but the first one will not show - I can preview it using ffmpegX but when I convert it, it does it in about half a second - no file appears and the "i" button says:

    FFmpeg version CVS, Copyright (c) 2000-2004 Fabrice Bellard
    Mac OSX universal build for ffmpegX
    libavutil version: 49.0.0
    libavcodec version: 51.9.0
    libavformat version: 50.4.0
    Fri May 25 18:15:11 BST 2007
    , gcc: 4.0.1 (Apple Computer, Inc. build 5250)
    Input #0, mpeg, from '/Users/justin/Desktop/VIDEO_TS/part 1.VOB':
    Duration: N/A, bitrate: N/A
    No audio or video streams available

    the last line bothers me.... how can it preview it if there is no info?

    why did it do all the other parts but not the first?

    why is there not even a blank file?

    help anyone??

    thanks

    If you still have the DV, then you could convert from that, and get better quality as a bonus: one conversion (DV > MOV) instead of two (DV > DVD > MOV).

    how can it preview it if there is no info?
    The preview uses mplayer to read the file, your conversion uses ffmpeg to read the fille. Two different decoders with different results.
    Try converting to XviD mencoder, which uses mplayer to decode.

    A normal VIDEO_TS folder has no files named 'part 1.VOB', but files named like
    VTS_01_0.VOB
    VTS_01_1.VOB
    VTS_01_2.VOB
    VTS_01_3.VOB
    I suppose you renamed the files?
    What size is your part 1 file? Is it a movie or a (motion) menu?
    Do your parts make one continuous movie, or are they 4 separate movies (like selectable from a main menu)? If the parts make one continuous movie, you may try joining the VOBs and converting the one big file.

    Thanks Case

    I don't have the original DV only the DVD.

    tried the mencoder option - same result:

    Yes I renamed the file.

    It's a movie - but the little glimpse I had opf the last mencoder attempt looked a little like a menu - but was only a fraction of a second.

    The size is 24Mb - all 4 parts are roughly the same size - joining them sounds like a good idea...
    will go check out the link now...

    thanks

    Some of the tools in ffmpegX do not like spaces in the path or filename, which may be the reason for this 'File not found'-error. Remove the space in the filename or replace it with an underscore character.

    then tried the mencoder and got a massive error list - this one created a file but it had no preview and was only a few Kb:

    This one didn't error on the path or name, so I didn't expect any change here.

    The length of the log doesn't necessarily mean loads of errors. mencoder is just really wordy about what it is doing/trying.

    The last line doesn't look like a regular finish of an encoding. I see warnings, but no errors in the log. I suppose you did wait for the Progress window to say Finished or Failed?

    A change in framerate is odd for a DVD, actually for most movie files. There are some file formats that support variable framerate, but I never thought of VOB being one of them. Conversion of VFR files may be problematic for many encoders.
