If you are talking about the incomplete/unstable Avisynth 2.6 pre-alpha Wilbert built back in 2006, it can be found in this thread:
http://forum.doom9.org/showthread.php?t=114643

For something more recent, and possibly more broken, you would have to build it yourself from source.

What I understood is that the frames will be analysed 4 times (running 4 mvxxx in parallel), which is the big advantage of the mt branch of mvtools (1 multithreaded analysis used for 1 multithreaded call of mvdegrain). Anyone correct me if I'm wrong.
oh, and just to be sure you got that, setmtmode(mode=2, thread=whatever works best for you) should be used for mvt.

OK, that got me. The Wiki explanation/pictures http://avisynth.org/mediawiki/MT_sup...etMTMode.28.29 shows consecutive frames getting farmed off to independent threads - which seems to imply (especially with 4 threads) that anything which relies on consecutive or near consecutive frame comparisons won't be getting what it thinks it is ? It'll get every 4th frame if you have threads=4, by the looks.

This further explanation of the SetMTmode (especially mode 2) http://avisynth.org/mediawiki/MT_modes_explained shows the separate threads processing separate frames ... which did nothing to dispel my fear on the effects on MV stuff.

Still confused on whether setMTmode plays nicely with the MV stuff (I'd like to stick with Fizick's gear rather than the "multi" stuff)

Other way to explain, mvdegrain2 example:

Code:
Thread 1 : process frame 330 - analyse frame 328,329,330,331,332 / process frame 334 - analyse frame 332,333,334,335,336

Thread 2 : request frame 331 - analyse frame 329,330,331,332,333 / process frame 335 - analyse frame 333,334,335,336,337

Thread 3 : request frame 332 - analyse frame 330,331,332,333,334 / process frame 336 - analyse frame 334,335,336,337,338

Thread 4 : request frame 333 - analyse frame 331,332,333,334,335 / process frame 337 - analyse frame 335,336,337,338,339

Return frame 330 (t1) + 331 (t2) + 332 (t3) + 333 (t4) and so forth
(and of course when I say frame x, it means "motion vectors from requested frame to frame x")

At least, that's what I think it does. (Logical assumption)
Therefore, it works "normally" except that the analysis is done in each threads (the same calculations can be done multiple times in different threads)

Is that clearer?

Thankyou. Trawling back through pages, I noticed http://forum.doom9.org/showthread.ph...92#post1108192 where posts 832-837 and thereabouts refer to mvtools, where example scripts are shown.

Cyberbeing, this was all the information that was given to me about it.

2.6 from pbmtp on HCFR. Is this the incomplete and unstable one built by Wilbert?

Ill use search next time and try using the incomplete and problematic programs before asking someone for the link to the ones that worked.

Thanks

Is it Necessary to put SetMT Mode twice in this script? One more time above the MCTemporalDenoise line?

Ive noticed that many people use set mode multiple times for various dlls. I do understand that different dlls react differently to varous setmodes or may not even work.

Do I have to put setmode for each filter used even if both of them may be a setmode2 dll?

SetMTMode(2,0)
AVISource("C:\Users\baba\Desktop\VTS_01_1.avi", audio=false)
#deinterlace
Converttoyv12()
#resize
#denoise
Import("C:\Users\baba\Desktop\MCTemporalDenoise\Deblock_QED.avs")
Import("C:\Users\baba\Desktop\MCTemporalDenoise\LSFmod.v1.3.avsi")
Import("C:\Users\baba\Desktop\MCTemporalDenoise\MCTemporalDenoise.v1.1.24.avsi")


MCTemporalDenoise(settings="medium", gpu=false)

No, it is valid until another SetMTMode call.

They say use mode=5 as the 1st line before the avisource or whatever and then another setmtmode, say 2, after that.

Ill Try that halsboss. I tried taking my source and doing my resize and deinterlacing to a lossless avi. I used lagarith. Set the avi to YV12 and added the audio stream I wanted. Ran it through VirtualDub. 35-40fps. Then I run the avi as script again through Virtualdub with only my cleanup (ex MCTemporalDenoise()). Gives me another boost of about 1.2-1.5fps, which takes hours off of an encode. So the first 30-45min pass to lossless is a good trade off and saves me time. I never would of thought about it until I noticed different resizers caused significant slowdowns on encoding. Bicubic seems to be the fastest. Lazsco seems slower.

but ill try mode 5 ont tope and then mode 2 above my denoiser.

Thanks

OK. You could try mode=2 just after your avisource if there's other things you do before your denoiser...

Is there any way to speedup this simple script using MT?

avisource("Source1.avi",false)
Lanczos4Resize(720,340).Addborders(0,70,0,70)
AssumeFPS(23.976,false)

MT works on 2.5.8?
thanks!

Ctrl + F resize

The latest MT build is based on 2.5.7

I think there are many people which are hesitating to switch to 2.5.8 because there is no multithreading enabled avisynth.dll available. I guess the MT.dll of version 0.7 might still work for 2.5.8 but the patched avisynth.dll is missing...

It's a show-stopper for me. The elapsed-time savings benefits of setMTmode with it's multi-threading are just way way way too good to forego.
