Program to automatically capture every Xth frame of a clip?

Discussion in 'Amateur Video Production' started by Tom Gustafson, Dec 11, 2003.

  1. Hello everyone,

    I have been a long-time reader of this group and this is my first post.
    I am looking for either a program or method for automatically
    capturing every Xth (30 or 60 or some random number) frame of clip as a
    jpg or gif. My goal is to do a "high-light" clip of a pre-existing and
    edited clip. I am using Vegas 4.0 for my video editing.

    Thanks for any help in advance,
    Tom

    You can use SnatchIt to grab any number of frames automatically from a
    video.

    If it is DV video, you can use ScenalyzerLive. Excellent program -- best
    $33 I've ever spent.

    I believe Scenalyzer can do that.
    (Called "time-lapse" or somesuch?)

  5. I have looked for that feature but still not found it. Where IS that
    time lapse thing? All I can find is preprogrammed start and stop times.

    VirtualDub can do this. <http://www.virtualdub.org/>. Set decimate
    frame rate, then save as image sequence.

    Scenalyzer Live is a great capture program, and it does capture
    individual frames, but as far as I can tell it cannot do so
    automatically on some kind of interval. You have to actually advance
    to the frame and hit a button each time to select it SnatchIt works
    the best for this purpose.

    Thanks for the tip to use VirtualDub! I already have it on my system
    and it worked like a charm! The only question I have is if it possible
    to change the file format VirtualDub saves the pictures as? It gives
    the option of BMP or TGA and BMP works fine, but jpg would save some space.

    Thanks again for the help,
    Tom

    There is an option in the capture settings that lets you capture 1 in every X
    frames. So, for a one-frame-a-minute timelapse, you'd capture one in every
    1800 frames (approximately).

    ScLive has a terrific interval capture setting -- I've used it to capture 1
    frame in 30 & so create a compact dv.avi archive file -- you can capture an
    entire tape to a file small enough to fit on a CD-R, you can play it back
    with any computer that uses WMP, and though the file will permanently play
    at 'high speed' ... there are no artifacts, and a freeze or still export
    generates a 'perfect' frame ... and the timecode data is preserved from tape
    & so still makes for useful batch capture information. A useful way to
    archive b-roll tapes.
