            2 .SH NAME
            3 blind-time-blur - Draw new frames on top of old frames with partial alpha
            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.
