For an .avi file, I can read in the file using video = VideoReader(filename) and then read the first frame using readFrame(video) which gives me an array of type uint8. How do I read aeach frame?

Note, you can save a 3D/4D matrix of the video if memory permits by defining a variable as such:
ii = 1;
while hasFrame(vidObj)
vidFrame(:,:,:,ii) = readFrame(vidObj); %vidFrame(:,:,:,ii) for color image and vidFrame(:,:,ii) for gray image
ii = ii+1;
end
