How to speedup smoothFPS2 script for avisynth?

[marcorocchini]

Hi, and however I'm a cat.

I have this .avsi for avisynth:

function SmoothFPS2(clip source, int num, int den) { 
super = MSuper(source, pel=2, hpad=0, vpad=0, rfilter=4)
backward_1 = MAnalyse(super, chroma=false, isb=true, blksize=32, searchparam=3, plevel=0, search=3, badrange=(-24))
forward_1 = MAnalyse(super, chroma=false, isb=false, blksize=32, searchparam=3, plevel=0, search=3, badrange=(-24))
backward_2 = MRecalculate(super, chroma=false, backward_1, blksize=8, searchparam=1, search=3)
forward_2 = MRecalculate(super, chroma=false, forward_1, blksize=8, searchparam=1, search=3)
backward_3 = MRecalculate(super, chroma=false, backward_2, blksize=4, searchparam=0, search=3)
forward_3 = MRecalculate(super, chroma=false, forward_2, blksize=4, searchparam=0, search=3)
MBlockFps(source, super, backward_3, forward_3, num, den, mode=0)}

it works ok but seems a little slow. Is there a way to improove speed? thanks

Do you have idle/slack resources ? What is CPU usage ?

You can speed it up a bit with multithreading

e.g
Prefetch(4) #or some number

You can run avsmeter64 to measure script speeds, but there is interaction with encoder threads too (you should test final encoder speed)


Or sometimes SVPFlow GPU variant might be faster on some GPU/Hardware setups , but the output is slightly different (sometimes better, sometimes worse)

With 64 bit AviSynth+, converting a 1920x1080p24 video to 60p, I get:

prefetch(1): 47 fps
prefetch(4): 102 fps
prefetch(8): 158 fps

That's output fps (60), not input fps (24). It gets a few percent faster with more threads but peaks out around 165 fps.

It's all about setting up AVISynth to use multiple threads. How to do this depends on the version of AVISynth.

Time to update, your avisynt+ build is 6years old

ok c*t

I have installed avisynth+ 3.6.0

and download SVPflow 4.2.0.142

my base-script is:

Import("v:\automazioneclip\avisynth\plugins\IResize.avsi")
Import("V:\automazioneclip\AviSynth\plugins\smoothFPS2.avsi")
Import("v:\automazioneclip\AviSynth\plugins\FrostyBorders.avsi")
Import("v:\automazioneclip\AviSynth\plugins\CropResizedic2017.avsi")
LoadPlugin("v:\automazioneclip\AviSynth\Lsmash64perVirtualDub64\LSMASHSource.dll")
LoadPlugin("V:\automazioneclip\AviSynth\plugins64\ffms2.dll")
LoadCPlugin("v:\automazioneclip\avisynth\plugins64\yadif.dll") 
vid=FFVideoSource("V:\gopro2\GOPR4184 1080 24 fps.MP4")
aud=FFAudioSource("V:\gopro2\GOPR4184 1080 24 fps.MP4")
left=GetChannel(aud, 1)
right=GetChannel(aud, 2)
both=mergechannels(left, right)
audiodub(vid, both)
ConvertAudioTo16Bit()

ConvertToYUY2(interlaced=false)

SmoothFPS2(50000,1000) 

AssumeTFF().SeparateFields().SelectEvery(4, 0, 3).Weave()

AssumeFPS(25)

where I need to replace SmoothFPS2 that do the conversion of FPS --> into a new framerate.

What is the the new script?

I need to insert:

LoadPlugin("V:\automazioneclip\AviSynth\plugins64+ \svpflow1_64.dll")
LoadPlugin("V:\automazioneclip\AviSynth\plugins64+ \svpflow2_64.dll")

and then? consider that I have a NVidia GTX 1060 board and if possibile I would like use the GPU hardware capabilities

[jagabo]

The SVPFlow documentation has examples.

Prefetch(4) #or some number

if I have a i7-9700K processor, what number I need to put?

[jagabo]

Whatever value it takes to maximize throughput.
