FFT3DGPU x64 error: Evaluate: Unrecognized exception

[Gargalash]

Hello all,
I am experimenting with avisynth x64 and its x64 filters.

I am going though the list of available denoisers and I've hit a wall trying to user FFT3DGPU. As mentioned in the title, I get the following error when I open the script in Vdub x64: Evaluate: Unrecognized exception. It points to this line in my script: FFT3DGPU()

My whole script is this:
LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins64\FFT3dGPU.dll")
AVISource("C:\blabla.avi")
FFT3DGPU()

The only hint I found was possibly 2 missing D3Dxxx_42 dlls. I have those in system32 and have also replaced them with the ones provided by the person who ran in the same problem and who solved it with these dlls.

I've reached that point where I have to ask for help!
Any clues what is causing this?

Thanks!

Install:

To use this filter you need directx 9.0c or better and a graphics card supporting directx 9 in hardware. That is at least an ATI Radeon 95xx or Nvidia Geforce fx 5xxx. Geforce 6xxx or better is recommended. If you have downloaded the installer just run it and you're done, else copy fft3dgpu.hlsl and copy FFT3dGPU.dll into the same directory from the 7-zip archive, also install the latest version of directx (april 2006 or later). You can get it here or extract the file d3dx9_30.dll (not included in the archive) to the c:\windows\system32 directory. The installer will copy d3dx9_30.dll to the right location meaning that it shouldn't be neccesary to run the directx installer if you have Directx 9c installed.

I've met all those conditions precisely.

Avisynth open failure:

The 32bit variant of FFT3dGPU works without problem. The 64bit version doesn't work at all, for me.

Mounir,
Thanks for your resumé of the conditions to have it work. I know have it working! My problem was that I hadn't put fft3dgpu.hlsl with FFT3dGPU.dll in my plugin folder.

I have a PAL progressive source filtered with FFT3DGPU(), default settings, and a video analysis pass in virtualdub gives me between 183 and 189 fps with this card (http://gigabyte.com/products/product-page.aspx?pid=3569#ov). Is this a number I should expect?

One last question: If I run only FFT3DGPU, I still have my cpu running at 50%. My source is DV (43 min. 9gb) on my SSDs. Could the cpu usage be caused by the fast decompression of the video file?

Thanks again for the information!
