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 direct 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 corresponding pixel and frame.
