Dogway's Filters Packs

[ChaosKing]

Not sure if it affects only the gpu version but the readme says

Lowering the value of "block_step" will be useful in reducing blocking artifacts at the cost of slower processing.

But I have stopped using any of the BM3D filters.

Why??

And you'll have re-direct these,

LoadPlugin("%AVISYNTHPLUGINS%\BM3DCUDA\BM3DCUDA_AVS.dll")
LoadPlugin("%AVISYNTHPLUGINS%\BM3DCUDA\BM3D_VAggregate_AVS.dll")

mainly BM3DCUDA, to BM3DCPU.

Good luck.

Thank you

Well, one encode I did using BM3D CUDA, a particular scene had a large lake in the background, and it was all "swirled up" (not the water), and looked terrible, encoding it with BM3D CPU it was good, so that was enough for me.

But I am using medium settings with pre-filter 2, pretty happy with the results.

Try Lowering the value of "block_step"

So I would have to add this to the "call"...

video=SMDegrain(video,tr=4,thSAD=400,thSADC=200,thSCD1=400,thSCD2=130,contrasharp=true,prefilter=pre,str=1.2,refinemotion=true,block_step = [8,8,8])
or
pre=ex_BM3D(video,sigma=5,radius=1,block_step = [8,8,8])  with or without the brackets ?

Are you sure this is an Avisynth option ???, 'cause I can't get it to work.

[kedautinh12]

Try
pre=ex_BM3D(video,sigma=5,radius=1,preset="normal")
video=SMDegrain(video,tr=4,thSAD=400,thSADC=200,thSCD1=400,thSCD2=130,contrasharp=true,prefilter=pre,str=1.2,refinemotion=true)

What's better as a prefilter regarding quality? DFTtest or BM3D? I like the idea to run prefiltering via the GPU but not if quality is compromised.

I changed the preset for BM3D from "fast" to "normal" but can't go any higher as my GPU card is running out of memory with the higher settings and the GPU also slows down my CPU.

Hi ked, thanks yet again, that has worked (meaning no errors), yet to try an encode

Hi LeXXuz,

I did quite a few encodes once I got all these pre-filters setup, and I think it is up to the individual, to which one is better.

I am currently using pre-filter #2, which in "Minblur". and it's pretty good.

Cause preset="normal" will increase r to 3. You will need more ram, vram to do with this preset and your encode will slower than fast and low. You can change preset to "low" will suitable with your machine

So just "fmi" (for my information), is "fast" the default setting, if you haven't got this command in the script ??

[kedautinh12]

Your default setting if you don't add preset parameter is preset="low"

Thanks...I just tried a "normal", and it's a lot slower....

Try edit 3 from here to 2 or 1. Your encode speed will increase very much

Is that the "radius" setting ??

I'm running "radius=1", atm.

Value below "np" you can change 3 to 2 or 1 for more speed in encode

So something like this ??

pre=ex_BM3D(video,sigma=5,radius=1, preset=normal, np=3)

Lol
Value "3" in this line

After edited, try again with this scripts
