FPS and Halo?

[Gedrin]

Hi,

iam new to avisynth (and also this forum) :-)

I want to encode a Anime (Avatar - The last Airbender) and found 2 threads to start with. Thread 1 (http://forum.doom9.org/showthread.php?t=141433) & Thread 2 (http://forum.doom9.org/showthread.php?t=143687)

I tried everything mentioned in this threads but the result was still horrible. So i tried myself for the last week and i found a way that the output isnt that bad anymore. But iam still have halo, i hope someone can help me, to tune the script a bit.

This is my Script:

DGDecode_mpeg2source("H:\AVATAR_BK1_VOL1_EUR\VIDEO_TS\VTS_04_1.d2v", info=3)
ColorMatrix(hints=true, interlaced=true)
animeivtc(mode=4)
crop(6, 0, -4, -4)
BlindDeHalo3()
Undot()
sharpaamcmod()
saa()
FastLineDarken()
Spline36Resize(720,576)


The other problem is, the file is now at 20 FPS it should be 25, what iam doing wrong, in the d2v the frame_rate is set to 2500 (25/1), does that convertion happen thru AnimeIVTC?

AnimeIVTC reverses 23.976 FPS -> 29.97 NTSC, Not for 25 FPS.

EDIT: And welcome to the forum.

Hi StainlessS,

oh, i misunterstood the docs. I didnt get, that the fps convertion with mode=4 is obligatory. Tonight i encoded with animeIVTC(mode=2), now i have a 25 fps video without the stutter and the halo is almost gone, so maybe the Euro Version of the DVDs is not Hybrid (like the NTSC Version), and my problems where from mode=4. :rolleyes: Thanks for your hint :-D

But now i have a new one, the deinterlace isnt that good anymore.

Hello Gedrin, is always best to post a sample from the source aka no re-encoding.
I'm curious to see if the halos are just as bas as the NTSC dvd?
I started trying to fixed it but the halos are very strong and it seems I cannot remove them without killing detail.
I decided to put it off for now, I'm hoping to learn a couple of things between now and then. :)

EDIT:

Have you tried removing AnimeIVTC out of your script?

Hi,

i see, here is a m2v sample (https://www.box.com/s/sav7x64ub6hh592s13qn) (converted from vob to m2v with projectx and cut with MpegSchnitt) the clip is 62.50 MB (00:01:12) (took an hour to upload with my connection...).
I dont know if the source is better, i never saw the NTSC version in Action.

My first attempt was with MeGUI and it used yadif, but the result was terrible, after a google search i found the 2 threads mentioned above and tried animeivtc the result was much better (but the encoding is extrem slow ~2fps, i can even use placebo preset in x264 without time loss :rolleyes: )

Thanks for re-uploading your sample. Here's a sample (http://www.mediafire.com/?xgoj3oz3lucg486) of the NTSC DVD. So it seems that the PAL version is worst than the NTSC version.
Unfortunately the PAL DVD does seem to be interlaced and it does have blended frames. For deinterlacing I suggest you try QTGMC, for it's quality the speed it's alright.
Don't know if it's possible but you may also want to return it and get your self a copy of the NTSC DVD.

Here are some other threads regarding Avatar and it's problems:

Hi,

thanks for the NTSC Sample and for the hint with QTMC. I still have to try out many things (QTGMC Noisereduction and all that stuff), but for now i tried with this


QTGMC( Preset="Slow", SourceMatch=3, Lossless=2, TR2=2)


i still have to tune something out, like Sharpening and the order of the filters (its currently to blurred), but this encoding seems very promising. Demo - 13 MB (https://www.box.com/s/ibphxpck3zco3vq9xtlq)

I cant return the DVDs they are a few years old already ;)
