getframe

FRAME=GETFRAME(VR)
  Returns the current frame that has been read in from video VR.  Calling
  GETFRAME does not automatically advance the current frame so the user
  must first call NEXT, STEP, or SEEK before calling GETFRAME the
  first time.  This makes it easy to write loops such as:
    vr = videoReader(...);
    while (next(vr))
      img = getframe(vr);
      ...do something...
    end
    vr = close(vr);
