As a video is just a bunch of pictures and pictures are just matrices you can subtract the two frames (or matrices) to find the differences. How you want to analyze the data or define change (e.g. - is it 5% change or less or more) I will leave up to you. This should put you in the right direction tho:
v = VideoReader('test.mp4');
framePrev = readFrame(v);
% Loop through video frame by frame
while hasFrame(v)
frameCurrent = readFrame(v);
frameCompare = frameCurrent-framePrev;
imshow(frameCompare)
framePrev = frameCurrent;
end
