    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 their are also reverted to non-interlaced. If input was non-interlaced, only do remove duplicated 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).
