            2 .SH NAME
            3 blind-split - Split a video, by frame, into multiple videos
            4 .SH SYNOPSIS
            5 .B blind-split
            6 [-L]
            7 .RI ( file
            8 .RI ( end-point

           10 .RB ' end '))\ ...
           11 .SH DESCRIPTION
           12 .B blind-split
           13 reads a video from stdin and splits into multiple videos.
           14 Starting from the first frame in stdin, it writes a video
           15 to the first specified
           16 .I file
           17 until the first specified
           18 .I end-point
           19 number of frames have been written.
           20 .B blind-split
           21 then proceeds to write the following frames to the next
           22 specified
           23 .B file
           24 until a total of
           25 .I end-point
           26 frames has been written (that is, including all previous
           27 videos), where
           28 .I end-point
           29 is the associated
           30 .IR end-point .
           31 If
           32 .RB ' end '
           33 is used instead of
           34 .IR end-point ,
           35 .B blind-split
           36 will proceed until the end of the input video. If you
           37 want to discard a section of the video, you can specify
           38 the
           39 .I file
           40 /dev/null.
           41 .P
           42 All specified
           43 .IR end-point s,
           44 including
           45 .RB ' end '
           46 must be in strictly ascending order.
           47 .P
           48 The specified
           49 .IR file s
           50 may be of any type, except directory, including pipes
           51 and FIFO:s. Indeed you probably want all of the to be
           52 pipes, as saving a raw video to disc will probably fill
           53 your disc almost immediately. If you are levering the
           54 power of
           55 .BR make (1)
           56 to only rerended parts you have changes, you can
           57 pipe the videos into
           58 .BR blind-to-video (1)
           59 to compress them. If you're shall does not support
           60 process substitution or creating anonymous pipes, you
           61 can uses FIFO:s. If you try to truncate a FIFO, it
           62 will be flushed, if this is done after all writes have
           63 been done, the process reading from the FIFO will think
           64 that there no longer are any processes that have it
           65 open for writing, assuming it, like all
           66 .B blind
           67 tools, have been written to treat the file as any a
           68 regular file (which is usually have pipes are also
           69 treated).
           70 .SH OPTIONS
           71 .TP
           72 .B -L
           73 Ignore the number of frames specified in the videos head
           74 and read until the end or the last desired frame is reached.
           75 If this option is used in combination with
           76 .RB ' end ',
           77 the last video will have an incorrect frame count written
           78 in its head. Depending on what tools you will being using,
           79 you may need to save that video into a regular file and
           80 rewrite its head with
           81 .BR blind-rewrite-head (1).
