Approximately,
idx = 0;
while hasFrame(videoobject)
idx = idx + 1;
stored_frames{idx} = readFrame(videoobject);
end
Note: If the video is stored in a file, then I would recommend reading the file through once just to count the frames so you can pre-allocate the stored_frames variable.
Also, it can be more efficient to instead use a multidimensional numeric array instead of using cell arrays.
