NAME
     blind-stack - Overlay videos

SYNOPSIS
     blind-stack [-b] bottom-stream ... top-stream

DESCRIPTION
     blind-stack  prints  the  video  from the file bottom-stream to stdout, but
     draws the videos from the succeeding arguments on top  of	the  video  from
     bottom-stream, drawing them in order, starting with the video specified di-
     rect  after  bottom-stream and ending with top-stream.  The specified files
     can be any type, except directory, including pipes.

     The output video will be as long as the longest input video.

OPTIONS
     -b     Instead of drawing the videos on top of each other, for  each  pixel
	    in each frame, print the average colour for each input stream's cor-
	    responding pixel and frame.
