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.

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).
