    You could use jit.uldl->disk->jit.matrix importmovie or - >jit.matrixset. However, have you tried using asyncread with 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 is only taking up more RAM, not eating CPU in this case.

      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.
