[BUG] Avisynth TemporalDergrain 2 FFT3DFilter&FFT3DGPU Crash

[Selur]

preview window sometimes with 2-3 filters does

sometimes with some unknown filter,... details?
If you can reproduce it, let me know and I can look into it.
Keep in mind that TemporalDegrain(2) were designed for SD content, so if you use HD content or above with the default setting or even more demanding settings than the default it can take quite a while of the filter to update,...

The example you asked...

The debug output shows that:

Yes but the preview window didn't appear...
As I mentioned in an earlier post...
"The frames are synchronized now but the preview window sometimes with 2-3 filters does not open, while in the Jobs queue the encoding takes place normally... "

[Selur]

Okay, then the debug output should an example there that happens and not an example where you encode something.

[Euangelos]

A few tests the encoding is done with shutter encoder. None of them showed a preview window

[Selur]

Accoding to the debug output, the avsViewer is newer started.
(there's no 'startPreview call: ...')
Can't reproduce this here so far.

Can you write a exact step-by-step of what you are doing?

(Tests 4 & 5 & 6) Avisynth-->QTGMC slow & Despot & SpotRemover & TemporalDegrain 2 FFT3DGPU (previous current next frame 3D, Limit FFT: GPU, P.Sigma 3)

Ok finally after about 2 minutes it did open the preview ... Is this time normal for a 100minute footage?  
Can I Increase the performance? add more threads ? It barely use the cpu and I have 16 cores 32 treads...

[Selur]

a. Avisynth isn't as good as Vapoursynth in regard of threading
b. TemporalDegrain and TemporalDegrain2 are not fast to begin with especially on higher resolutions (+ your settings and Despor&SpotRemover)
c. 'QTGMC(Preset="Slow", ediThreads=2)' is slow,...
d. jumping inside uncompressed YUV is slow too
=> what did you expect
