Hi,
I was wondering if there's a snippet of code that can save movies smaller than the typical avi? My system cannot find any codecs, so I thought mp4 would be better. But that's getting complex fast as I read about it. Here' my sample:
Z = peaks;
surf(Z)
axis tight manual
ax = gca;
ax.NextPlot = 'replaceChildren';
loops = 40;
F(loops) = struct('cdata',[],'colormap',[]);
for j = 1:loops
X = sin(j*pi/10)*Z;
surf(X,Z)
drawnow
F(j) = getframe(gcf);
end
fig = figure;
movie(fig,F,2);
movie2avi(F, 'awesomeMovie', 'compression', 'None');
Seems videowriter may have potential, but I cannot find an example I understand, based on my example above.
Hoping for some help, and thank you. Dave

'compression', 'none' would be much bigger than AVI.
Which operating system are you using?

Here's an example of how to use VideoWriter. Try it for different formats: wmv, mp4, etc.
