I am using writevideo to make a movie while creating the images. I have gotten it to work before however, this time it is skipping the last frame although I haven't changed the code. the code is:
if true
narr_anim(7) = struct('cdata',[],'colormap',[]);
myVideo = VideoWriter('dove_anim.avi');
myVideo.FrameRate = 1;
open(myVideo);
for m = 1 : 7
narr_anim(m) = getframe(gcf)
writeVideo(myVideo, narr_anim);
end
close(myVideo);
end
Am I missing something?

Maybe use
narr_anim(m).cdata
in your loop? Other than that your code looks fine to me

vlc doesn't even play the video. It opens the first frame, runs the length of the movie but doesn't show the other images.

videowriter captured all the frames and if I stop WMP it shows the last frame. But during playback, WMP goes black before the last frame is rendered.
