Hi Jordan,

I'm using Matlab 5.3 and MakeQTMovie from April 10, 2000. So I guess I have the
latest versions.
Here's how I make a movie:
MakeQTMovie start
MakeQTMovie ('quality',1)
MakeQTMovie ('framerate',5/dt)
axis([min(min(xx)) max(max(xx)) min(min(yy)) max(max(yy)) min(min(T_res))
for j=1:5:t
for i=1:elr+1
temp(:,i) = T_res(nodes_temp+(i-1),j);
MakeQTMovie ('addfigure')
end % for j=1:t
MakeQTMovie finish
Am I doing anything wrong here?
