 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/
