It would be useful to have a visual diff tool for videos that will create
a resultant differential video of two videos. This could be used in a
number of scenarios from simply seeing more easily the differences of one
encode to the next to many other applications.
With some overlay+pad magic you should be able to compare img1,img2 and
diff on the same image. Similarly should function with vid frames.
It would be useful to have a few different styles of diffing from an
outline to color inversion and clipping similar to what is demonstrated
here: http://jeffkreeftmeijer.com/2011/comparing-images-and-creating-
image-diffs/
