            8 [-r

           11 .I width

           17 .SH DESCRIPTION
           18 .B blind-from-video
           19 converts the video, in the file
           20 .IR input-file ,
           21 to a format usable by the
           22 .B blind
           23 tools, and prints the new video to the file
           24 .IR output-file .
           25 .I input-file
           26 and, unless -L is used,
           27 .I output-file
           28 must be regular files.
           29 .I input-file
           30 must be a normal video file with a container (i.e. not raw video)
           31 that is supported by
           32 .BR ffmpeg (1).
           33 It is unspecified what happens if
           34 .I input-file
           35 does not have exactly one video stream. All non-video streams,
           36 such as audio and subtitles are discarded.
           37 .P
           38 If
           39 .B output-file
           40 is omitted,
           41 .RB ' - '
           42 (stdout) is used.
           43 .SH OPTIONS
           44 .TP
           45 .B -d
           46 Perform coarse colour-model conversion. This will increase the
           47 performance of the conversion, but modifications to the colours
           48 will not produce the expected colours. This is useful for
           49 drafting or if you will not modify the colours. If you use this
           50 flag, you should also use it in
           51 .BR blind-to-video (1),
           52 otherwise the colours will be modified.
           53 .TP
           54 .BR -F " "\fIpixel-format\fP
           55 Select pixel format, see
           56 .BR blind-convert (1)
           57 for more information. Pixel formats starting with
           58 .BR raw ,
           59 other than
           60 .BR raw0 ,
           61 are not supported.
           62 .TP
           63 .BR -h " "\fIheight\fP
           64 Change the height of the video to
           65 .IR height .
           66 .TP
           67 .B -L
           68 Write to stdout that the number of frames in the video is 0.
           69 This allows you to use a non-regular file, including a pipe, as
           70 .IR output-file .
           71 If you specify
           72 .RB ' - '
           73 as the
           74 .IR output-file ,
           75 the video is printed to stdout.
           76 
           77 This option is useful if you want to split a video, into
           78 multiple videos, as it allows to to split the video without
           79 having to store the entire raw video to disc.
           80 
           81 If you use this option, you can use
           82 .BR blind-split (1)
           83 to write the actual number of frames to the head, if this
           84 is needed.
           85 .TP
           86 .BR -r " "\fIframe-rate\fP
           87 Change the frame rate of the video to
           88 .IR frame-rate .
           89 This value can be a rational.
           90 .TP
           91 .BR -w " "\fIwidth\fP
           92 Change the width of the video to
           93 .IR width .
