    I am looking for an tool where I can easily convert a batch of DV AVI
    files from 16,66 frames/sec to 18 frames/sec.
    (the speed/duration of the file need to be changed, not the framerate;
    this is 25/sec and must remain 25/sec)

    I am currently using Ulead Video Studio, but here I have to apply these
    settings for each file, and there is not a button to convert 1 one
    batch a lot of files.

    Anyone suggestions?

    P.s. I am looking for this solution because I am capturing video at
    16,66 frames/sec on a PAL camera (50 frams / second) so that there is
    no flicker of the video visible. But I need to recalculate the speed to
    have the original speed back.

    Hope someone can help me here.

    I'd try VirtualDub first. Don't forget that changing the "playback
    speed" MUST generate some artifacts...which VirtualDub has various
    filters to minimize. Also note that you could have captured your film
    at 18.0 fps and then used VirtualDub's (actually: Donald Graft's)
    "deflicker" filter to remove. It works very well (read the readme or
    it won't work at all). Then you wouldn't have temporal artifacts to
    remove. Good Luck!

    Hi,

    I tried virtualdub, but couldn't find the right settings/options to
    change the speed.
    Normaly in Vide Studio you set the speed of the video at 108%, and this
    does the job.
    Anyone suggestions what settings to use in Virtualdub?

    Thanks,
    /Edwin.

    At the top of the VirtualDub window, left click on "Video", then left
    click on "Frame Rate". Change the frame rate to your preference. Test
    the results. You may want to apply the de-interlace and de-flicker
    filters. The "right" settings are are in your eye.

    If I change frame rate, the duration of the video does not chanage.
    I.e. 1 minute of source video remains 1 minute in the target file.
    What I need is that the target duration changes from 1 min to 1/108% ->
    approx 55 seconds.
