How do I read video frames starting at an arbitrary frame number

I am using MatLab 2014b 64 bit Windows. I have a .mov file with 13170 frames of 1080x 1920 pixels- way too big to read in all at once so I want to read the file in in chunks of 1000 frames each, but cannot find a way to start reading at a specified frame number. Are there parameters to set in VideoReader that does this?

You have to use read() and pass it the frame number.

% Extract the frame from the movie structure.
thisFrame = read(videoObject, frameNumber);

See my attached demo.
