maybe thats because i'm saving via virtualdub from 2013?

maybe, but post the script and sample clip

We know only little about your video. May it have a height which is not at least a multiple of 4? And the whole workflow has so many variables... no details - no clue.

By the way: Get up to date, use VirtualDub2. It's superior, especially in cooperation with AviSynth+ (and VapourSynth).

vorob · 13th August 2018, 07:10

Looks like multithreading was wrong, instead of SetMTMode (5, 6) i had SetMTMode (4, 8).

What's the best lossless codec? With smallest size? I used Lagarith, but i dunno it's ffmpeg command.

I've got only prores one, take a look:

ffmpeg -i "Washington, Datcha.avs" -c:v prores -profile:v 3 -pix_fmt yuv422p10le "Washington, Datcha_Deint.avi"

Since I just copypasted this line from another tutorial, can you help me with underlined part? What should i put there to have Lagarithone? Prores weigh too much.

Well, Lagarith will 'weigh' much more as ProRes is lossy.

Assuming this video is from a video8 tape you might want to think hard about whether storing this as 10 bit 4:2:2 lossless isn't a bit overkill.

LigH · 13th August 2018, 08:13

A lossless codec with good compression and wide support (both supporting different raw formats, and being supported in software with ffmpeg core) is the Ut Video Codec Suite (VideoHelp Software archive).

magiblot · 13th August 2018, 15:15

FFMpeg is unable to encode with Lagarith, but VirtualDub/2 can (although you must configure the codec within VirtualDub so that it will use YV12, YUY2 or RGB compression).

StainlessS · 13th August 2018, 16:16

Some time ago, it kind of surprised me that Lagarith could produce considerably smaller files than UT_Video, when source has
quite a few duplicate frames, I had just assumed that UT_Video would produce null frames as Lagarith does.

This Lagarith Arithmetic encoder problem is later debunked as rubbish by someone well known of the D9 (Cant find it or remember who)

Apologies if this has been answered, but I can't find anything on it... Is there a way to run QTGMC multithreaded in Vapoursynth?

Yes, havsfunc

Perfect, thanks!

EDIT: for anyone else wanting to use StaxRip Vapoursynth with sweet multithreaded power, just open the havsfunc.py file in Notepad++ (or Notepad, but the layout will be messy) and replace all instances of

Code:

core = vs.get_core()

with the number of threads. For example, I'm rocking two 10-core Xeon E5-2630v4 CPUs, so in this case it would be

Code:

core = vs.get_core(threads=40)

Can confirm QTGMC works perfectly on this. I set x264 for Very Slow, Threads: 18, Lookahead Threads: 9, Sync Lookahead: 250.

3-4 instances encoding at once maxes out all 40 threads

More threads in x264 results in worse image-quality.

I'm trying to use this plugin but i can't get to work.

I've installed this Core QTGMC.

Code:

C:\Program Files (x86)\AviSynth+\plugins64+\masktools2.dll  [2.2.18.0]
C:\Program Files (x86)\AviSynth+\plugins64+\mvtools2.dll  [2.7.31.0]
C:\Program Files (x86)\AviSynth+\plugins64+\nnedi3.dll  [0.9.4.51]

C:\Program Files (x86)\AviSynth+\plugins64+\SMDegrain.avsi  [3.1.2.100s]

When i try to do a simple option as this

Code:

QTGMC(Preset="slower")

Give me this error

Code:

System execption - Illegal Instruction

C:\Program Files (x86)\AviSynth+\plugins64+\QTGMC.avsi line 879
C:\Program Files (x86)\AviSynth+\plugins64+\QTGMC.avsi line 636

What i do wrong?

Since for "slower" NNEDI3 is used, probably the crash occurs in that module. You'll need to specify your exact processor type for the solution (which I suppose will be a bugfix)

But happens in all presets from Very Fast to Placebo.

Which of the nnedi3 DLLs from the package are you using?

And does your CPU support AVX2 at all? Which CPU do you have exactly?

DeafYakuza · 20th October 2018, 12:56

This is my first question that I'm asking.

I have some problems with QTGMC V3.34 with Avisynth 2.6.
Can someone maybe help me what it means?

Code:

TemporalSoften: Scenechange not available on RGB32
(QTGMC.avsi. line 413)

I installed that as following like here: https://forum.doom9.org/showthread.php?t=156028

But the problem didn't be solved.
What I want to do with that. I want deintalace a video. It's an avi (UT Video Codec).

Quote:

SetMemoryMax(512)
AVISource("myvideo.avi")
QTGMC(Preset="Slower", SourceMatch=3, Lossless=2, EdiThreads=1)
SelectEven()

I am grateful for your support.
