Hi. I am trying to create avi movies using fairly high resolution figures rendered remotely over an ssh tunnel. Ssh -X does not work because it takes too long for the rendering to take place, and besides, what I'd really like to do is not have the figures displayed at all--I just want the final movie saved into the current directory. I've been using

F(i) = getframe(gcf)

inside a loop, and then

movie2avi(F,'moviename')

after the loop is complete. This works fine on-site (aside from tying up the display for long periods of time,) but I'd really like to perform this operation remotely in the background, or even to pipe the command to MatLab via a bash script, again in the background. I even tried using saveas() to simply save .png images that I could convert later, but the rendering appears to be too much for MatLab. Any suggestions?

When you ssh in, is MATLAB running with the JVM, or just in a shell? If it's the latter then it won't work, because you can't have any figures. If it's the former then you can use print.
