I'm very happy with FFT3DFilter output result but it slow 8-9 fps (on my bad laptop :D ) is there any filters that can produce same or better output with better speed?

I was using this script and avspmod gave me 8-9 when I run the analysis pass


LoadPlugin("C:\megui\tools\dgindexz\DGDecode.dll")
DGDecode_mpeg2source("C:\Users\Admin\DVD 1\VIDEO_TS\VTS_01_1.d2v", info=3)
ColorMatrix(hints=true, interlaced=true, threads=0)
Load_Stdcall_Plugin("C:\Program Files (x86)\AviSynth 2.5\plugins\yadif.dll")
Yadif(order=1)
crop(0, 12, 0, -16)
FFT3DFilter(sigma=2.0, plane=0, bw=32, bh=32, bt=3, ow=16, oh=16, sharpen=1, interlaced=true)


Here is the comparison http://screenshotcomparison.com/comparison/43204

FFT3DGPU, obviously. Though you need a decent GPU in your laptop for that.

You could try the one of multi-threaded versions of AVISynth, if your laptop has more than one core. Use SetMTMode().

Thank you guys.. I will buy soon good desktop and will try there the FFT3DGPU.. at the moment I will try the other two options.. Thanks again..

Hmmm, don't know if I'm hallucinating or not. IIRC Groucho2004 uploaded an Intel compiled FFT3DFilter?
If this is not the case just ignore me :) if so, do you mind sharing it again?

I did - but removed it after I realized that it was behaving oddly in some scenarios. Also, the speed gain was marginal, in some cases it was slower than the "official" version.

I'd still recommend DFTTest for frequency domain denoising.
