BLIND-TIME-BLUR(1)	    General Commands Manual	    BLIND-TIME-BLUR(1)

NAME
       blind-time-blur - Draw new frames on top	of old frames with partial al-
       pha

SYNOPSIS
       blind-time-blur alpha-stream

DESCRIPTION
       blind-time-blur reads a video from stdin	and a mask video  from	alpha-
       stream.	The first frame	from the video is printed to stdout as is, and
       the first frame from the	mask video is ignored. Succeeding  frames  are
       drawn on	top of the last	frame printed to stdout, with its alpha	cannel
       multiplied pixel-by-pixel by the	product	of the luminosity and the  al-
       pha  from  corresponding	pixel in the mask video, and then printed std-
       out.

       If stdin	is longer than alpha-stream, the remainder of stdin is printed
       without	any  changes.	If stdin is shorter than alpha-stream, the re-
       mainder of alpha-stream is ignored but may be partially read.
