yuvkineco(1) MJPEG tools manual yuvkineco(1) 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 re- move duplicate frames. Interlaced frame detection may fail in condi- tions 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. -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 (de- fault: 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 differ- ence 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 deinterlac- ing process will run on all of frames. To disable deinterlac- ing process, specify negative value. -u Set interlace information in header of output to unknown (de- fault: non-interlaced). AUTHOR yuvkineco was written by Kawamata/Hitoshi.
