Need help with Proper Inverse Telecine for Anime
Hey guys, I have a NTSC DVD of an Anime that I want to encode. It is @ 29,97fps.
Every combination of tff() and tdecimate() that Ive tried so far didnt help get rid of all the interlaced frames or produced some progressive half-transitined frames. here I uploaded a small example file without sound, a short clip. [to be replaced] I hope tsmuxer didnt screw up the pulldown. Last edited by Guest; 15th April 2013 at 02:09. |

Please edit your post to give us a different sample. It should be about half as big and family friendly. Thanks.
There is irregular soft pulldown so for sure you will need to honor pulldown. But I will tell you more when you provide a new sample. Last edited by Guest; 15th April 2013 at 02:18. |

It is a M2V file I didnt find a proper tool that cuts m2v without reencoding it. Thus muxed it with tsmuxer and cut it with tsmuxer.. Tsmuxer didnt reencode the file, I hope. It couldve changed something with the pulldown though, which I also hope it didnt.
I will upload another short clip, fact is, its not a common pulldown. I couldnt find a script that gets rid of all interlaced frames or at least the some progressive frames have a half information, a mix of previous fullframe and frame after.. |

It came from dvd ofcourse, where else? I demuxed the streams with DVDdecrypter, it has an option to demux the streams from the DVD.
It then gives u all separate ac3 adio lines and the video as .m2v. It also demuxes Chapters from dvd and subtitles. if I demux the vob files with dgindex- what type of files does it give? MPEG? Last edited by 8-BaLL; 15th April 2013 at 15:25. |

Also before Srestore() there are 2879 frames and after Srestore there are 1201. Thats less than half the frames. From 29 to 24 should be more frames left I assume? Can you now put the thread in the normal section pls? It doesnt seem like many ppl traffic in the newbie section... Last edited by 8-BaLL; 15th April 2013 at 20:36. |

Thanks alot I will try it out with QTGMC.
It is the way how the anime is most of the time, a mix between still scenes and then some moving. I'll upload another example with more movement if the SRestore() doesnt work. Thanks. Edit: @manono- wow it really seems to work, no more interlaced frames and no more progressive mix-frames. If it wasnt pulldown, what method exactly was used here? Thanks again a ton. Its weird- I used a preset on QTGMC (very slow) and now it shows some mix images again in between... By changing back to QTGMC() they progressive mix images still remain. Its very frustrating. Looks like QTGMC + SRestore (23.976) wasnt the total solution though... I still get there a couple of mixed images. Last edited by 8-BaLL; 15th April 2013 at 21:43. |

The unblenders aren't perfect, particularly at scene changes. You can thank the fly-by-night company that released this garbage for it being field-blended in the first place. Anyway, I don't see what you see in frame 921. You were moving around in the timeline and when you do that Srestore gets 'confused'. Sort of 'sneak' up on it. Move the VDub slider to a place before 921 and then advance to it. Or just encode the whole thing without doing anything else after opening it. Here's what I see for frame 921:

Ok thank you, I think I got it now. SRestore does get confused indeed.
The source does seem to have very stupid field-blending. So annoying. does your frame 916 look like this? Those are very unsatisfying results, but its the dvd mastering company to blame. Would manual IVTC help here? Last edited by 8-BaLL; 15th April 2013 at 22:27. |

Yes, I see the same. As I said, sometimes the scene changes are problematic. There are two ways to handle this sort of thing, if you feel the need. One would be to go through the whole thing manually and FreezeFrame all the blended frames with a good one before or afterwards. For example, with that frame 916:
FreezeFrame(916,917,917) which replaces 916 with the better 917. The other is to dupe all frames on both sides of a scene change: A=Last prev = A.selectevery(1,-1) next = A.selectevery(1,1) SCclean = A.SCSelect(next,prev,A,dfactor=2.0) # 2.0 ~ 5.0 SCclean It needs an additional filter, RemoveDirt. It's automatic, but dupes all the good frames as well as the blended ones on either side of the scene change. With anime this isn't so much of a problem, because of all the duplicate frames to begin with. |

Thank you manono. Doing it manual is just insane I could spend days with it replacing blended frames. I think its not worth the effort.
The second method however distorts movemet in some scenes. I guess Ill have to accept the blended frames. One more thing though, on another anime it looks like it has native 12fps. Should I use SRestore(12) or SRestore(11.988)? It looked slightly better with 11.988, well it appeared to have less blended frames. THat cartoon is weird too, it has interlaced duplicates of every progressive frame. And it also has some field-blended frames which arent duplicates of anything. It look to be some sort of pulldown 12 fps anime to 25fps pal. |
