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 alpha

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 alpha  from  corre-
     sponding pixel in the mask video, and then printed stdout.

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