See the VideoReader and VideoWriter classes. If you have an older version of MATLAB, see mmreader()

See my sample code: http://www.mathworks.com/matlabcentral/answers/30847-how-save-frames-that-exit-from-video-in-a-specific-folder
It extracts frame and writes them to disk, then it shows how to read those frames back in and create a movie from them.
