Avisynth MT x64 Unable to load

[Nixeus]

Hello my friends,

I woule like to encode a dvd to a mp4 (x624) with Megui using the Avisynth MT x64. I have installed this AviSynth properly according the readme file.

Here is my AVS Script :

LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins64\MT.dll")
setmtmode(2,0)
LoadPlugin("E:\Users\xx\Downloads\MeGUI_2050_x86\tools\dgindex\DGDecode.dll")
DGDecode_mpeg2source("E:\PLACEBO\VIDEO_TS\VTS_01_1.d2v", info=3)
LoadPlugin("E:\Users\xx\Downloads\MeGUI_2050_x86\tools\avisynth_plugin\ColorMatrix.dll")
ColorMatrix(hints=true, threads=0)
#deinterlace
#crop
#resize
mergechroma(blur(1.3)) # Little Noise

When i save the file, i have a error : Unable to load MT.DLL

Have you an idea please ?

Thanks a lot,

Best regards,

Nixeus

You don't need to load MT.dll - your script does not use it.
It's not needed in order to use SetMTMode.

1.) Don't use 64-bit avisynth.
2.) You're not even using any functions from MT.dll
3.) Don't use 64-bit avisynth.
4.) Your script should be fast as shit anyway without any threading.
5.) Don't use 64-bit avisynth.

Thanks a lot for these fast answer,

So,i need to stay with Avisynth 32bits standard.
How can i speed my encoding process with megui ( I have a core i7 (8 thread )).

Need i to replace some dll ?

Thanks a lot,

Best regards,

I don't know which encoder you are using but with an i7 (and the script you posted above) you should get reasonable speed.

If this is still too slow you'll either have to overclock the chip or get something like an i7 990 or some badass dual Xeon setup.

Of course, this would only be beneficial if the encoder can utilize all the cores efficiently -> x264).

Yes , but why i don't need to use the 64 bits and why in don't need to use the MT version in order to get speed ?

I don't understand.

Avisynth standard don't use Multithreading no ?

The official versions of Avisynth are not multi-threaded. As long as you have simple scripts, this is not a problem because Avisynth can serve the frames fast enough to the encoder.

Once you add filters which for example perform denoising or deinterlacing (MDegrain, QTGMC), Avisynth will quickly become the bottleneck in the encoding process.
In these cases one can try to use one of the various MT versions floating around although they can be prone to crashing.

There is a 64 bit version of Avisynth but this is also not official and you have to exclusively use 64 bit filters with it.
This only makes sense if you run out of memory because of heavy filtering.

Bottom line: Use official, single threaded versions of Avisynth if your scripts are fast enough not to starve the encoder.
