NAME

       yuvkineco - revert 2-3 pulldown movie

SYNOPSIS

       yuvkineco [options] [-C PATH]
       yuvkineco [options] -O|N PATH

DESCRIPTION

       yuvkineco  reverts  to  original non-interlaced frames, from NTSC video which was film sourced and 2-3 pulled down.  Input fps code must be
       4(29.97fps), output fps code can be selected from 1(23.97fps) to 4(29.97fps). If 2, 3 or 4 selected, duplicated frames remain but they  are
       reverted  to  non-interlaced.  If input was non-interlaced only remove duplicate frames.  Interlaced frame detection may fail in conditions
       like:
	   Pull down cycle changed (video editing).
	   Low quality pull down.
	   Motionless scene.
       If -C PATH was specified, yuvkineco outputs 2-3 pull down cycle list to the file.  You can edit this file by hand and feed it to  yuvkineco
       with -O or -N option to correct mistake of 1st yuvkineco.  Try -C and see cycle list.
	 EXAMPLE #1: for 24p movie / automatically

	       yuvkineco -F 4 | yuv2lav -f a -I 0 -o 30p.avi
	 EXAMPLE #3: for 24p movie / check and repair

	       yuvkineco -F 1 -N 60i.23c | 
	       yuv2lav -f a -I 0 -o take2.avi
	 EXAMPLE #4: for 24p movie / check and retry
	   lav2yuv 60i.eli | 
	       yuvkineco -F 1 -C 60i.23c | 
	       yuv2lav -f a -I 0 -o take1.avi
	   glav -F +n take1.avi  # check and edit 60i.23c
	   lav2yuv 60i.eli | 
	       yuvkineco -F 1 -O 60i.23c | 
	       yuv2lav -f a -I 0 -o take2.avi

OPTIONS

       yuvkineco accepts the following options:

       -F FPSCODE
	       Set output fps code (default: same as input).

       -C PATH Specify 2-3 pull down cycle list file name to write.

       -O PATH Specify cycle list name to read with old yuv stream to retry.

       -N PATH Specify cycle list name to read with new yuv stream to repair.

       -S MIN  Use yuvycsnoise(1) as preprocessor and specify minimum threshold.

       -n LEVEL
	       Specify noise level of input (default: 10).  This affects both pulldown cycle detection and deinterlacing.

       -c THRESHOLD
	       Specify	threshold to decide pictures in 2 frames are same (default: 4).  yuvkineco compares several frames, searches pair of frame
	       they contain same pictures, to decide which frame should be dropped.  If THRESHOLD is 0, pair which has smallest difference will be
	       selected.  If 16, selected from pairs those have differences smaller than average.

       -i PERMIL
	       yuvkineco  deinterlaces	each  frame after 2-3 pulldown reverting process, specify how much pixels deinterlaced to decide to use or
	       not use deinterlacing result (default: 10).  If PERMIL is 10 and 1% or more of pixels deinterlaced, deinterlacing  result  will	be
	       used.   If  0, always deinterlacing result will be used.  If 1000, deinterlacing result will not be used, but deinterlacing process
	       will run on all of frames.  To disable deinterlacing process, specify negative value.

       -u      Set interlace information in header of output to unknown (default: non-interlaced).

NAME

       lav2yuv - Convert a MJPEG file to raw yuv

SYNOPSIS

       lav2yuv [options] lavfile1 [lavfile2 ... lavfileN]

DESCRIPTION

       lav2yuv	converts  an  MJPEG  video sequence described by a sequence of MJPEG video files and/or edit lists pointing to such files into the
       simple uncompressed planar 4:2:0 Y'CbCr format, as used by mpeg2enc(1) MPEG encoder and	image  processing  filters  like  yuvscaler(1)	or
       yuv2dfilter(1) or yuvdenoise(1).

       Output is to stdout so that by piping the output of lav2yuv into a suitable pipeline it is possible to process and then encode or play back
       video recorded in any of the mjpegtools MJPEG container formats: AVI, quicktime or edit lists describing editted versions of video held	in
       such files.

       Mixing different files with different video formats is currently not possible.

       The -S -T -D options are used for scene detection which is used by linux video studio.

OPTIONS

       lav2yuv accepts the following options:

       -m   Force mono-chrome

       -c   Conceal frames containing corrupt MJPEG data by repeating the preceeding good frame.

       -S list.el
	    Output a scene list with scene detection

       -T num
	    Set scene detection threshold to num (default: 4)

       -D num
	    Width decimation to use for scene detection (default: 2)

       -o num
	    Frame offset - skip num frames at the beginning.  if num is negative all but the last num frames are skipped

       -f num
	    Only num frames are written to stdout. 0 means that all frames are processed.

       -A width:height
	    Set/override  the  sample  aspect  ratio  (SAR)  emitted in the output stream header.  Currently, the SAR is only auto-detected for DV
	    files, and guessed otherwise.

       -P width:height
	    Set the intended/approximate display aspect ratio (DAR) for the stream.  This value is only used to guess the SAR when  it	cannot	be
	    detected  from  the  input	stream.   The default DAR is '4:3' (corresponding to a standard TV screen); another useful value is '16:9'
	    (corresponding to widescreen TV).

       -C chroma
	    Set output chroma (default: '420jpeg').  Currently, '420jpeg', '420mpeg2', '420paldv', '422' are available.

       -x   Exchange fields.  Useful if the field order was reversed during editing.
