How to correct errornous output of TFM+TIVTC (2pass VFR)?

[Kiichi]

Hello,

I just learned how to make VFR MP4 file via avisynth a few days ago (http://forum.doom9.org/showthread.php?t=128731). But my joy does not last too long; because I face another problem right after 1st success.

For better explanation I captured several original file and final results, also attached 2 pass log files generated by TFM and TIVTC. [Click this link to download (http://maid.hschen.idv.tw/~hschen/avs-vfr-question.rar)]

In most of scenes TFM and TIVTC managed to match correct fields and IVTC correctly. But as we can see in these 3 snapshot***.png, the output is combed. (There is more but I choose 3 of them as representative)

And there is another strange thing: the original d2v (see dbg**.png, not exactly the same frame but I make it as near as possible) have only some moving part combed, but the result have more combed parts than original.

Is there any way to fix it by adjusting parameter or any tool to fix it manually?
:thanks:

Using the "ovr" parameter you can specify a text file containing match/deinterlacing overrides. You could also try tweaking the combed frame detection parameters, check the readmes.

FYI, TIVTC is the name of the whole package. I think you mean TFM+TDecimate.

Did you try something like this?

movie=mpeg2source("C:\...",info=3) #info=3 for colormatrix hints, if you use it
assumetff(movie) #use appropriate tff/bff depending of field order, this is key, IMO
movie=tfm(movie,d2v="C:\...").tdecimate()
movie=ColorMatrix(movie,mode="Rec.709->Rec.601",hints=true,threads=0) #replace Rec.709 with appropriate source color thingy, this step is optional
last=movie

Using tfm and tdecimate and specifying field order should get rid of any combing, IMO.
The only problem with this is that it might drop a wrong frame here and there (and thats really rare, IMO), but you shouldn't see any combing, at least I think so.

You can also try using the ultimate IVTC tool, YATTA (Yet Another Telecide Tool for Anime).

Lucky Star fan, eh? :)
