BLIND-FROM-VIDEO(1)	     General Commands Manual	     BLIND-FROM-VIDEO(1)

NAME
     blind-from-video - Converts a regular, cooked video to a blind video

SYNOPSIS
     blind-from-video [-r frame-rate] [-w width -h height] [-dL] input-file out-
     put-file

DESCRIPTION
     blind-from-video  converts  the  video, in the file input-file, to a format
     usable by the blind tools, and prints the new video  to  the  file  output-
     file.   input-file  and,  unless  -L  is  used, output-file must be regular
     files.  input-file must be a normal video file with a container  (i.e.  not
     raw  video) that is supported by ffmpeg(1).  It is unspecified what happens
     if input-file does  not  have  exactly  one  video  stream.  All  non-video
     streams, such as audio and subtitles are discarded.

OPTIONS
     -d     Perform  coarse colour-model conversion. This will increase the per-
	    formance of the conversion, but modifications to  the  colours  will
	    not  produce the expected colours. This is useful for drafting or if
	    you will not modify the colours. If you use this  flag,  you  should
	    also use it in blind-to-video(1), otherwise the colours will be mod-
	    ified.

     -h height
	    Change the height of the video to height.

     -L     Write  to  stdout that the number of frames in the video is 0.  This
	    allows you to use a non-regular file, including a pipe,  as  output-
	    file.   If	you specify '-' as the output-file, the video is printed
	    to stdout.

	    This option is useful if you want to split a  video,  into	multiple
	    videos,  as  it allows to to split the video without having to store
	    the entire raw video to disc.

	    If you use this option, you can use blind-split(1) to write the  ac-
	    tual number of frames to the head, if this is needed.

     -r frame-rate
	    Change the frame rate of the video to frame-rate.  This value can be
	    a rational.

     -w width
	    Change the width of the video to width.
