Is there a way to create an MPEG movie frame by frame, such
as within a loop, similar to the addframe command used to
create AVIs?

I have tried using mpgwrite, but the arrays I am dealing
with are too large to store at once and are currently added
to an avi frame by frame.... such as (within a loop):

F = getframe(gca);
aviobj = addframe(aviobj, F);

I also tried using movieeditor to load the created AVI and
convert it to an MPEG, but when using 150 mb avi's, the
memory quickly balloons to 2 gigs and I therefore receive an
out of memory error.

Any ideas? Thanks all.
