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

NAME
     blind-to-video - Converts blind video to a regular video

SYNOPSIS
     blind-to-video [-d] frame-rate ffmpeg-arguments ...

DESCRIPTION
     blind-to-video reads a blind video from stdin and uses ffmpeg(1) to convert
     it  to  a normal video format.  frame-rate must be set to the frame-rate of
     the input video, lest the tempo in the output video be  modified.	You  can
     use  ffprobe(1)  (an ffmpeg utility) on your original video to find out the
     frame rate:

	  ffprobe -v quiet -show_streams -select_streams v -- your-video.mkv |
	  grep '^r_frame_rate=' | cut -d = -f 2-

     This value will be a rational value, which is supported.  All argumnets af-
     ter frame-rate (that is ffmpeg-arguments ...)  are arguments that	will  be
     passed  to  ffmpeg(1)  after  the arguments that blind-to-video will create
     that specifies the input file and necessary metadata such	as  frame  rate,
     geometry, and format, of the input video.	Beginners are recommended to use
     -c:v libx264 -preset veryslow -crf 0 -pix_fmt yuv444p -- output-file.

OPTIONS
     -d     Perform  coarse colour-model conversion. This will increase the per-
	    formance of the conversion, however, it the colours  will  not  look
	    correct,  unless  the  -d flag was also with blind-from-video(1) and
	    not colours have been modified between to the processes.
