Filters make the encode slower

[yaston]

Hello everyone,

I faced a problem using these filters "QTGMC()" and " dfttest()" they made my encode slower, i used them at once..., one by one but no way !!

What should i do?

Run QTMGC() in MT mode and get a faster computer.

How?! i don't know this step !! would you show me screens or explaine pleaze?

Filtering takes time, sometimes LOTS of time, that's just the way it is.

No no dear, this is wrong !! i don't do Blu-Ray even there's many ways...

I don't even OWN a Blu Ray, it doesn't change the fact that Filtering Takes Time.....period.
I run my NeatVideo filtered projects overnight.....ya' know why?....Filtering Takes Time

[yaston]

Yeah takes time but not like usual.... for me when i add "QTMGC()" it takes more and more

I made it !! still slower

How slow is QTGMC() running on your computer? What CPU do you have? How much memory?

On my i5 2500K, with 720x480 MPEG 2 video, with no other filtering and no encoding, QTGMC() runs about 15 fps with 1 thread. 45 fps with 6 threads. QTGMC(preset="fast") goes up to about 100 fps with 6 threads. Without QTGMC(), just reading the source video, runs about 500 fps.

SetMtMode(4,6)  # Mpeg2Source() requires mode 4, 6 threads
Mpeg2Source("VTS_01_1.d2v", Info=3) 
SetMtMode(2) # QTGMC can run in mode 2 (faster than mode 4)
QTGMC()

Slower than what? Post your full script. Benchmark your script with AVSMeter. Post the results.

Slower than it used....

Here's the full script, i stopped using "QTGMC" now i'm only use "dfttest"

dfttest is slow denoiser. QTGMC is slow deinterlacer. You also have a few sharpeners. And you are not using multithreaded version of avisynth. So, encoding will be slow.

So i have to use " Avisynth 2.6 MT " version, isn't it? Is the a difference in the use of dlls?

[Detmek]

Yes, you need avisynth.dll that supports multithreading. You can find it here or use this installer. The more cores your CPU have more improvement you will see in filtering speed.

But if your CPU already works at full or almost full load due to used encoder settings you will not see much improvement.
