qtgmc error "there is no function named removegrain"

[codemaster]

When I open the following avs file in VirtualDub

LoadPlugin("D:\users\Username\portable programs\DGMPGDec DGIndex\unpacked\DGDecode.dll")
MPEG2Source("D:\users\Username\temp\my d2v file.d2v")
AssumeFPS(25, 1)
AssumeTFF
QTGMC(Preset="Slow")
SelectEven()

a window with the title "VirtualDub Error" appears, which says:

Avisynth open failure:
Script error: there is no function named "RemoveGrain"
(QTGMC-3.32.avsi, line 756)
(QTGMC-3.32.avsi, line 781)
(QTGMC-3.32.avsi, line 386)
(D:\users\Username\temp\my avisynth script.avs, line 5)

The file "RemoveGrainSSE2.dll" is in "D:\installed programs\AviSynth\plugins".

Any solutions?

The AviSynth version that is installed on my PC is v.2.6.0 ST, 32-bit official build.

Does it work if you explicitly load it? Is your path at D:\installed programs\AviSynth\plugins
the default avisynth plugin folder

No.

Eventually, I found what works. The following solution worked:
- I deleted "RemoveGrainSSE2.dll" version 0.9 from "D:\installed programs\AviSynth\plugins";
- I copied "RemoveGrainS.dll" version 1.0b to "D:\installed programs\AviSynth\plugins";
- now there's no error when I open the avs file in virtualdub.

The strange thing is that it worked before, without having to replace "RemoveGrainSSE2.dll" version 0.9, with "RemoveGrainS.dll" version 1.0b. The only thing that changed since then is that I switched from Windows 7 (64 bit) to Windows 10 (64 bit), and I used the version of AviSynth 2.6 that was the latest then.

According to the doc, removegrainS.dll is the big statically linked version
with all dependencies built in. Thanks for the update

According to the doc, if there's a missing plugin error when using "RemoveGrainSSE2.dll", then there should be no error after replacing "RemoveGrainSSE2.dll" with "RemoveGrainS.dll".

But if I use "RemoveGrainS.dll" 0.9, I get the error "there is no function named RemoveGrain", and if I use "RemoveGrainS.dll" 1.0b, there's no error.

And last time I used QTGMC 3.32 and "RemoveGrainS.dll" 0.9, there was no error. It worked.

Interesting. My acquaintance with this function is limited but I've seen similar before. Perhaps some other dependency changed
somewhere along the line

RemoveGrain has been replaced by RGTools, which also replaces VerticalCleaner.dll, if you happen to be using it.

RGTools requires the Microsoft Visual C++ 2015 Redistributable Package. There's a link on the RGTools page, although you probably have it already if you're running Windows 10.

You might be using a bunch of outdated plugins. The latest version of QTGMC (3.357s) and it's required plugins can be found in this plugins pack, although a couple of the plugins have been updated since that pack was put together, so check the text file inside with links to each plugins, or there's an updated QTGMC wiki here with links to the current plugins.
