Filtering help needed

[x264]

The qtgmc plugins package contains only the 32 bit filters. Where can i find all the latest 64bit filters?

I don't think there are 64 bit versions of all the filters used by QTGMC().

Should i use tune - film for this source in x264?

I got this error when i used QTGMC 3.33d. How do i fix this? -- downloaded the QTGMC avs from this link http://doom10.org/index.php?topic=2202.0

You need a different version of MDegrain1() (part of mvtools2), one that supports 32 bit precision (lsb=32). Or switch to an earlier version of QTGMC (I'm using 3.32). Or remove the lsb=32 arguments from the version you're using.

[LMotlow]

True. They come with the dither plugin package. Has dither's own versions of dfttest and mvtools.

You could do that, but I see posts where other problems pop up if you don't have the other dither plugins.

I'd ask the O.P., what's wrong with the "real" QTGMC? If it's speed you want, that modded version will slow you down.

I thought that the QTGMC 3.3d mod will be better than the 3.32 version.

I encoded an interlaced dvd using the above script. How do i remove the flickering at the start of the video?(from frame 730 - 850)

[manono]

Am I alone in thinking it's playing in the wrong aspect ratio? I see nothing 4:3 about it. It's 3:2, I think. I have to set my player (MPC-HC) to play it at 4:3 so everyone's not fat.

That section is animated at 30p so it's inherently flickery. The only way you can remove the flicker is to use motion interpolation techniques (probably won't work very well). Or maybe some frame blending.

<edit>

It worked better than I expected. You can see some distortions when examining still frames but they're not very visible at full frame rate playback.

import("C:\Program Files (x86)\AviSynth 2.5\plugins\DoubleFPS2.avs") 

ffVideoSource("P90x.mkv") 
p1=Trim(0,639)
p2=Trim(640, 849).SelectEven().DoubleFPS2()
p3=Trim(850,0)

p1+p2+p3

You can find DoubleFPS2() by searching the forums here.

[x264]

Is this the script for doublefps2?

function DoubleFPS2(clip source)
{
super = MSuper(source, pel=2, hpad=0, vpad=0, rfilter=4)
backward_1 = MAnalyse(super, chroma=false, isb=true, blksize=16, searchparam=3, plevel=0, search=3, badrange=(-24))
forward_1 = MAnalyse(super, chroma=false, isb=false, blksize=16, searchparam=3, plevel=0, search=3, badrange=(-24))
backward_2 = MRecalculate(super, chroma=false, backward_1, blksize=8, searchparam=1, search=3)
forward_2 = MRecalculate(super, chroma=false, forward_1, blksize=8, searchparam=1, search=3)
backward_3 = MRecalculate(super, chroma=false, backward_2, blksize=4, searchparam=0, search=3)
forward_3 = MRecalculate(super, chroma=false, forward_2, blksize=4, searchparam=0, search=3)
MBlockFps(source, super, backward_3, forward_3, num=2*FramerateNumerator(source), den=FramerateDenominator(source), mode=0)
}

Should i call this function before or after QTGMC?

[jagabo]

Yes, that's the DoubleFPS2() filter I used. You have to call it after QTGMC(). Note that the section of the video has 30 different pictures per second, each one duplicated to make 60 fps after QTGMC(). You need to throw out one of those duplicates in order for DoubleFPS2() to work. Hence the SelectEven() in my sample code.

Thank you very much for the script, it looks much better now.

How do i join two mkv files encoded using the same settings from the same DVD? The first mkv contains 20,000 frames and the next mkv contains the rest of the frames.

[jagabo]

MMG, Add first, Append second.

--sar calculation

4/3 = 704/476 * x/y

x/y = 4*476/3*704 = 119/432

Is the above calculation correct?

No. Using your numbers:

4/3 = 704/476 * x/y

(4/3) / (476/704) = x/y

4 * 476 / 3 / 704 ~= 0.9015 ~= 10:11 = standard SAR for 704x480 NTSC 4:3 DAR

I got this error when i tried to open a 10-bit mkv file in Solveig video splitter. What should i do to fix this?

[jagabo]

Use 8 bit encoding?

[x264]

Which software should i use for trimming 10bit videos?

[jagabo]

No idea. Why don't you trim before you encode?

[Selur]

MKV Cutter might work, if you replace the x264 binary which comes with it with a 10bit variant.
(+ I agree with jagabo, cutting before reencoding is normally the preferred way to go and not the other way around.)

[jagabo]

By the say, I don't know for certain that Solveig doesn't support 10 bit h.264, I was just speculating about that. But in general, many tools don't work with 10 bit h.264 and very little outside of a full blown computer can play it. That's a big tradeoff to get slightly better visual quality.

Which deinterlacing filter do you people use for deintelacing anime?

[manono]

Which deinterlacing filter do you people use for deintelacing anime?

That's too general a question to answer. Anime doesn't usually need deinterlacing. IVTCing, maybe. Unblending, maybe. But not deinterlacing, although the end result of both will be the interlacing is gone. If you have a sample you want to post we might be able to give an answer specific to the video.

[Selur]

yup, TIVTC, Restore, AnimeIVTC() are probably good points for starting,...

D2v file of the DVD - http://www.mediafire.com/view/mfbi8ym7zu87mhd/VTS_01_1.d2v

Samples : Main movie - http://www.mediafire.com/watch/48k44pyb9dmdr8h/VTS_01_1.demuxed.m2v
Closing credits - http://www.mediafire.com/watch/f2oz559q0fajd0x/ED.demuxed.m2v

[jagabo]

The main movie sample is 100 percent film. You can use DgIndex in forced film mode with that and there will be nothing to deinterlace/IVTC. The end credits are 30p. You could simply decimate that down to 24p like the rest of the movie. To be safe, use DgIndex in Honor Pulldown Flags mode, then TFM(d2v=...).TDecimate() the entire thing. Make sure there are no scrolling credits at the end -- they might get screwed up.

[x264]

What will happen to the closing credits when i use TFM().TDecimate() ?

[manono]

What will happen to the closing credits when i use TFM().TDecimate() ?

Nothing, they're static. I wouldn't even IVTC it. If the whole thing except for those static end credits is 100% film, I'd do the whole thing as Forced Film.
