Largest size video Matlab can import

I am trying to do image processing on a video that is ~46 GB. I realize this is huge and I will most likely have to break it up and do it by sections in order to import all the data.

The video is at 30 fps and is about 30 minutes long which comes out to be about 54,000 frames that I need to process.

What is the largest size section I can break the video into? I have both the image toolbox and the computer vision toolbox. What is the best way to go about this?

Thank you!

How much RAM do you have? How complex is your program? How much do you need to remember about each frame while you are processing later frames?
