           20 .SH DESCRIPTION
           21 .B blind-rewrite-head
           22 rewrites the head in the video
           23 .IR file .
           24 .I file
           25 must be a regular file. The new
           26 head will specify the choosen number of
           27 .IR frames ,
           28 the choosen
           29 .I width
           30 and
           31 .IR height ,
           32 and the choosen pixel
           33 .IR format .
           34 If
           35 .B ' same '
           36 is choosen as the
           37 .IR width ,
           38 .IR height ,
           39 or
           40 .IR format ,
           41 .B blind-rewrite-head
           42 will use the values specified in
           43 .IR file 's
           44 head. If
           45 .B ' auto '
           46 is choosen as the number of
           47 .IR frames ,
           48 the number of frames will be calculated from
           49 the length of the file, its geometry, and
           50 pixel format.
           51 .SH OPTIONS
           52 .TP
           53 .B -h
           54 Used if the video file does not have a head.
           55 This of course means that
           56 .RB ' same '
           57 cannot be used as there is not way to know
           58 the geometry or format of the video if it does
           59 not have a head.
           60 .SH RETIONALE
           61 .B blind-rewrite-head
           62 only support regular files because combining
           63 .BR blind-read-head (1),
           64 .BR blind-write-head (1),
           65 and
           66 .BR cat (1)
           67 is sufficient for doing the same operation on pipes,
           68 but not on regular files that are too large to store
           69 two copies of on disc.
