    You could use jit.uldl->disk->jit.matrix importmovie or jit.qt.movie -

    jit.qt.movie and URLs? This does the work in a background thread.

    Not if the movie is stopped and not being banged. So using 9
    instances of jit.qt.movie is only taking up more RAM, not eating CPU
    in this case.

      efficiency
      I found mxj.jitwebimage
      to be a good way to download images.
      Another good thing to know is that you can use "importmovie" and just import pictures into a matrix without the quicktime object.
      Employing either of these might help.
