	4 .SH SYNOPSIS
	5 .B blind-time-blur
	6 .I alpha-stream
	7 .SH DESCRIPTION
	8 .B blind-time-blur
	9 reads a video from stdin and a mask video from
	10 .IR alpha-stream .
	11 The first frame from the video is printed to stdout
	12 as is, and the first frame from the mask video is
	13 ignored. Succeeding frames are drawn on top of the
	14 last frame printed to stdout, with its alpha cannel
	15 multiplied pixel-by-pixel by the product of the
	16 luminosity and the alpha from corresponding pixel
	17 in the mask video, and then printed stdout.
	18 .P
	19 If stdin is longer than
	20 .IR alpha-stream ,
	21 the remainder of stdin is printed without any changes.
	22 If stdin is shorter than
	23 .IR alpha-stream ,
	24 the remainder of
	25 .I alpha-stream
	26 is ignored but may be partially read.
