QTGMC Deinterlacing Script (v3.32)

[Boulder]

Have you tried triple quotes: JDL_ApplyRangeOld(6428, 6466, """QTGMC(Preset="placebo").selecteven()""") ?

[LigH]

You cannot embed a string with "single double-quotes" in a string with "single double-quotes"; to circumvent this limitation, there are also strings with """triple double-quotes""".

JDL_ApplyRangeOld(6428, 6466, """QTGMC(Preset="placebo").selecteven()""")
__

Apart from that: A preset named "placebo" uses this name for a specific purpose ... to make you feel bad using it, because it is rather a waste of time than "the optimum".

that one current moment, need placebo. this is hwy i don't want use it on a whole title, rest i will sue with medium.

thank you for help !

I tyr "" "", but didn't thoguht about """ """. (*´ー｀*)

Everything is documented, in the internet as well as in your local installation.

I want to convert 1080i50 to 1080p25. Is there a way to have no noise reduction thus making it possible for me to use SMDegrain later?

[fvisagie]

I haven't used this mode, but your best bet is probably the "Noise Bypass / Denoising" section in the documentation. The following seems to be key for your objective:

Important: You must use a non-zero value in one of EZDenoise, EZKeepGrain or NoiseProcess or no noise processing will occur

Cheers,

The original post seriously needs example scripts so it can help newer people like me..

I'm trying to use QTGMC with AVSProxy for AVIDemux. I took all the right steps to install my plugins for the deinterlacer, but I'm stuck on the scripting part of it, what am I doing wrong?



AviSource(C:\Users\Owen\Desktop\deinterlacetest.avi)
QTGMC(Preset="slower")

[LigH]

The name of the AVI file is a string literal and belongs between double quotes.

I would assume that the error message would have given a hint.

No it doesn't, as your problem has nothing to do with QTGMC. This filter is among the best documented of all AviSynth filters and there are examples galore in the included doc. As LigH wondered, didn't you get an error message? Next time open a script in VDub to test and it'll tell you something helpful if there's something wrong with the script.

Anyway, as LigH also suggested, add quotation marks:

AviSource("C:\Users\Owen\Desktop\deinterlacetest.avi")
QTGMC(Preset="slower")

And maybe it's OK, but I never do anything at all from the desktop.

I never said my problem had anything to do with QTGMC? I've been around the block before with using temgaussmc, and I got an error to the point of 'unexpected something something'' which I knew meant something was wrong with my script. I don't think I ever said anything was wrong with the QTGMC filter. Anyways, the quotations around my file address worked! Thanks LigH.

The original post and provided documentation with the file gave no real examples of how to set the first line, I was literally left looking for half an hour before I wound up asking. I was lucky enough even to remember that I had to write the whole path, because I remember talking with an avidemux admin about it long ago.

The result seems to have worked, but now I get a flickering artifact on the encoded video. One of the very first frames of the video is constantly flickered against the video itself. I can't seem to find a solution or workaround in the documentation either.

I don't use vdub to write scripts, I just notepad documents in which I give an .avs to their names.

Yes you did. You implied QTGMC was at fault when it wasn't. Your problem was writing the AviSource line correctly, something very basic to AviSynth and nothing to do with QTGMC.

And therefore the original post needs nothing of the sort. And as I said, the included doc is full of good examples. But none of those examples show the line needed to open the video in the first place as it's assumed you would have learned that by now.

The original post and provided documentation with the file gave no real examples of how to set the first line.

And there's no reason in the world it should as it's about using the filter and not about opening a video. That kind of basic information is found on the AviSynth website on pages such as this one:

http://avisynth.nl/index.php/First_script

...and I got an error to the point of 'unexpected something something''...

And it pointed to the AviSource line in the script, and not the QTGMC line?

I don't use vdub to write scripts, I just notepad documents in which I give an .avs to their names.

So do most people, including me. I mentioned VDub as a way to test out your script, not to write it.

...but now I get a flickering artifact on the encoded video.

Please make available a sample from the source, before the QTGMC step. Ten seconds with steady movement will be plenty, a section you think gets 'flickery' after the use of QTGMC.

[LigH]

For more convenience than Notepad, there is also the old VirtualDubMod with integrated AVS editor (Ctrl+E), or the more modern AvsPmod suite.

Still ... "RTFM", know the basics before advancing.

Actually it seems as though avidemux is causing issues with the AVI files I created from the TS files to use with avisynth in the first place-- the audio and video do weird things.

I'll relearn how to load up TS files through directshow. This issue has nothing to do with QTGMC so I'll ask it elsewhere.

[wonkey_monkey]

Does anyone know why, when I try to QTGMC a clip with audio (provided by nicac3source) I get this error:

Avisynth open failure
Cache: Filter returned invalid response to
CACHE_GETCHILD_CACHE_MODE.93484280

But if I leave out the audio, there's no problem. Is this by design, i.e., QTGMC is just not meant to be run on clips with audio?

It means you are using a plugin compiled as API version 5 but it is not a full API version 5 plugin.

Typically a 2.6 plugin compiled with an old or modified avisynth.h

If you use early release 2.6 plugins you must make sure they are compatible with the build of Avisynth 2.6 you are using.

[wonkey_monkey]

Ah, thanks!

Ok, I have gotten my .ts files loaded thanks to other members of the forum. Now then, it seems as though I'm in need of some additional filters on my script with qtgmc, or perhaps might need something entirely else to get maximum quality out of the type of video I'm processing. Below are 4 pictures, each of yadif and qtgmc preset slower.

qtgmc 1
yadif 1

qtgmc 2
yadif 2

qtgmc 3
yadif 3

qtgmc 4
yadif 4


With only 'qtgmc(preset=slower), I notice more ghosting/ringing effects on qtgmc compared to yadif, and some of the jaggies around diagonal edges aren't as smoothed as I would liked them to have been. Basically it's not quite the jump in quality I'm looking for.

Also, I've tried searching the thread for 'slow motion' but couldn't find any answers as to why qtgmc slows the resulted video down, even though I made it output in the same 30fps as my previous files.

Any thanks would be appreciated.

That's probably due to the way you made it output in the same 30fps as my previous files. QTGMC is a bobber. It will natively give you back twice the number of frames at twice the framerate (60fps in your case). If you simply add in 'AssumeFPS(30)' to your script, then of course it slows it down. If you add in ConvertFPS(30), then you get that blended crap you're blaming on QTGMC. If you add in 'SelectEven()' instead, then it halves the frame count and you get back your 30fps at the original speed. And no blending.

Anyway, as already requested, please post a short sample. And also your full script.

Here is a 1 minute sample of the video still interlaced. I had to re-encode it using x264 again with avidemux to get it under 200mb. Original .ts was using h264 as well.

Here is my script:

LWLibavVideoSource("C:\Users\Owen\Desktop\test1.TS")
QTGMC(Preset="slower")
SelectEven()
