A video is simply a sequence of individual images. You know how to get things like centroid, perimeter, etc. already. Recall that you are a university instructor of MATLAB courses who develops workshops for MATLAB students at engineering colleges. Plus I've been showing you over the past year or two, and I know you've seen my demos in my File Exchange and demos that I've posted in direct response to your questions. Since you already know how to do it for individual images, you already know what to do for a video.
If you need another demo, please see this demo on video analysis I uploaded just a few hours ago: http://www.mathworks.com/matlabcentral/answers/110291#comment_186462

Try this:
fileInfo = imfinfo('moon.tif')
message = sprintf('The file size = %d bytes.', fileInfo.FileSize);
uiwait(helpdlg(message));

The size required in memory would be the height times ceiling(the width times the bit depth divided by 8)
where ceiling is "the least integer at least as large as the given value" (e.g., "round up")
