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

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.

re-jit-matrixset-and-basic-patch-efficiency

Another good thing to know is that you can use "importmovie" and just import pictures into a matrix without the quicktime object.

I found mxj.jitwebimage
to be a good way to download images.
