Auto-crop letterbox AVI video possible ?

    Is there a video re-encoder which allows automatically cropping black letterboxes
    from a given DivX or Xvid encoded AVI video ?

    In AutoGK it automatically invokes an autocrop and resize feature.. I'm
    assuming you have a DivX file that has black bars?

    An example of what AutoGk does without any intervention: A 16:9 frame from
    DTV contains a 4:3 movie pillarboxed within the 16:9 frame, ie black bars
    either side. AutoGk automatically cuts off the black bars and resizes the
    image to fill a full 4:3 frame.

    It seems like I did run across such a feature somewhere,
    but sorry, I can't remember where.

    I use TMPGEnc 4.0 to crop input video with a "Filter
    template file" where I have stored the filters that I routinely
    apply to video I have captured. You can have as many
    such filter templates as you want.

    The one I'm talking about here I named
    "crop_resize_filter.txp4f" with it I apply cropping settings to
    match the letterboxing of my video source. If I had a source
    that gave me video that needed a different cropping setting,
    (or any other filtering) I would make another filter template,
    for that, with its particular settings.

    The filter template comes in handy when you are encoding a
    number of clips and some need cropping and others don't, as
    it lets you select the clips to apply a group filter to.

    So if you have a source of XviD or DivX, (or anything else)
    that consistently needs a certain cropping, you can make a
    template to automatically apply that cropping, to whatever clips
    you want. If some others require a slightly different cropping
    then make another template, for them.

    Luck;
