Hi,
I was able to create a video using nFrames = 10000 in MATLAB R2015b. I did make a couple of changes to the above code. I will illustrate the example using a plot of sine curve from 0 to 2pi rather than the plot used in the question above (I leave that to you for further modifications). However, I made a couple of changes to the code:
1. Instead of creating the figure each time inside the loop, declare it once outside the loop. It avoids creating unnecessary figure handles which in turn could exhaust the memory.
2. If the 'mov' struct array is being not used outside the loop, consider using a temporary variable inside the loop. The 'mov' struct array will also consume a lot of memory depending on the number of frames used. (In my case it works using both a temporary variable and a struct array).
writerObj = VideoWriter('SineWave.avi');
open(writerObj);
nFrame=10000;
hfig = figure('color','w','un','pix','pos',[360 550 450 400]);
axis([0 2*pi -1.5 1.5])
hold on;
time = linspace(0,2*pi,nFrame);
for nt=1:nFrame
plot(time(nt),sin(time(nt)),'marker','*');
% mov(nt) = getframe(gcf);
% writeVideo(writerObj,mov(nt));
mov = getframe(gcf);
writeVideo(writerObj,mov);
end
close(writerObj)
Hope making these changes helps. If this still does'nt work, then share the error message you receive. This would help in troubleshooting the issue.
