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
           lav2yuv 60i.eli | \
               yuvkineco -F 1 | yuv2lav -f a -I 0 -o 24p.avi
         EXAMPLE #2: for 30p/24p mix / automatically
           lav2yuv 60i.eli | \
               yuvkineco -F 4 | yuv2lav -f a -I 0 -o 30p.avi
         EXAMPLE #3: for 24p movie / check and repair
           lav2yuv 60i.eli | \
               yuvkineco -F 1 -C 60i.23c | \
               yuv2lav -f a -I 1 -o take1.avi
           glav -F +n take1.avi  # check and edit 60i.23c
           lav2yuv take1.avi | \
               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).
