	1 .TH BLIND-TO-VIDEO 1 blind
	2 .SH NAME
	3 blind-to-video - Converts blind video to a regular video
	4 .SH SYNOPSIS
	5 .B blind-to-video
	6 [-d]
	7 .I frame-rate
	8 .IR ffmpeg-arguments " ..."
	9 .SH DESCRIPTION
	10 .B blind-to-video
	11 reads a
	12 .B blind
	13 video from stdin and uses
	14 .BR ffmpeg (1)
	15 to convert it to a normal video format.
	16 .I frame-rate
	17 must be set to the frame-rate of the input video,
	18 lest the tempo in the output video be modified. You
	19 can use
	20 .BR ffprobe (1)
	21 (an
	22 .B ffmpeg
	23 utility) on your original video to find out the frame rate:
	24
	25 .nf
	26 ffprobe -v quiet -show_streams -select_streams v -- your-video.m…
	27 grep '^r_frame_rate=' \| cut -d = -f 2-
	28 .fi
	29
	30 This value will be a rational value, which is supported.
	31 All argumnets after
	32 .I frame-rate
	33 (that is
	34 .IR ffmpeg-arguments " ...)"
	35 are arguments that will be passed to
	36 .BR ffmpeg (1)
	37 after the arguments that
	38 .B blind-to-video
	39 will create that specifies the input file and necessary metadata
	40 such as frame rate, geometry, and format, of the input video.
	41 Beginners are recommended to use
	42 .B -c:v libx264 -preset veryslow -crf 0 -pix_fmt yuv444p --
	43 .IR output-file .
	44 .P
	45 If your output video need include an alpha channel, the codec
	46 .BR ffvhuff .
	47 Not all video players support videos with transparency.
	48 .BR mpv (1)
	49 is a good media player for previewing videos with transparency,
	50 however it distorts colour somewhat.
	51 .SH OPTIONS
	52 .TP
	53 .B -d
	54 Perform coarse colour-model conversion. This will increase the
	55 performance of the conversion, however, it the colours will
	56 not look correct, unless the -d flag was also with
	57 .BR blind-from-video (1)
	58 and not colours have been modified between to the processes.
