Try to reinstall / update ffdshow to the version bundled with SVP 3.0.6.

зря он кол-во потоков зарезал

Да как бы и не должен. Вообще внутри Avisynth вся обработка идет строго в 8 бит на канал, больше не будет.

Если просто использовать Avisynth скрипт в ffdshow

какой конкретно скрипт?
внутренние функции может быть иногда переварят 10 бит
mvtools - нет

But I think 15 threads should be enough even for 5:1 frame interpolation. 19 threads and more will produce more FPS in encoding but for real-time 15 is fine.

What would it take to get SVP on 64bit?

In the next 1<=N<=5 years - no way 

See the message above.

I can see Potplayer using ~1gb of ram b4 it crashes.

Hmm. For me 15 threads are working with both "pixel" and "half-pixel".
Anyway, if interpolation to 120 Hz will work well with 15 threads - you're lucky

Something is seriously wrong with your setup 

1. May be you've "Motion estimation accuracy" set to "To quarter-pixel"?
2. Does PotPlayer works with SVP turned off?
3. Post here "Show -> Additional information" after player crash
4. Do you've any codec packs installed?

a few beers for the new year
Thanks!

Yeah, I've just checked 2.6 alfa3, and confirm that simple script with only LanczosResize() is 1.5 times faster with 2.6.

So the simpliest solution for you is to unpack (not install) 2.6 and place it's avisynth.dll in MeGUI folder.

And SVP will not work with this 2.6 version cause it lacks MT functions.

Resizing is the only time consuming function here and it's a built-in Avisynth function.
May be it was improved in 2.6, something like sse2-3-4 

I don't know. May be it's just a difference between 2.5.8 and 2.6.0 with your script.

So your possible choices are:
- use SVP with your fast Avisynth. It should work, but will need more memory.
- use SVP with it's own Avisynth: you can place SVP's one in the video player's folder (near .exe file), then SVP will use this version instead of one located in SysWOW64.
And don't forget to remove/rename "avisynth.dll" from SVP\Distr\MT folder or else SVP will overwrite SysWOW64\avisynth.dll on each run.
