In the original video I get 11 seconds and in the new one 5 seconds. Anyone knows the problem?
outputVideo = VideoWriter('openv_v.avi');
open(outputVideo);
vid = VideoReader('openv.avi');
for idx = 1:vid.NumberOfFrames
img = read(vid, idx);
writeVideo(outputVideo,img);
end
close(outputVideo);

Solved with one line.
outputVideo.FrameRate = vid.FrameRate;
