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).
