Someone is over defensive. Let's just enjoy the updates.

Exactly! :)

What are the default values? Are the 3 param (Lambda, T, Tuv) floats? Ranges for these param are 0 -> +oo?
I appreciate the work and the share of it, but it would be nice if the readme could contain at least these info

[Soulhunter]

Ok, it seems there was a bug in FRFun rev1...

New version with better readme is on the way!

Thanks for the improved readme (and the fixed dll of course ^^)

Thanks SH. A very promising filter, indeed, growing better!

Just a little note: FRFun7 needs X and Y axis to be multiple of 8, otherwise it'll introduce green bars on the bottom and the right of the frame. So one has to place FRFun7 before crop or after resize (even between crop and resize, but cropping width and height with multples of 8).

Sorry for my english mistakes

I tried it on some mildly noisy mpegs: Awesome. Best ringing ("mosquito noise") removal ever, with so little damage to detail. I haven't tried it on really detailed work yet though. Needs a sharpener at the end to really bring out the best, though, since it slightly blurs lines.

Only thing I noticed is that it sometimes jumbles up banding pretty good - in the original it was a smooth gradient of bands (meh), after it's all disturbed. It'd probably look great if it didn't have to get truncated back to yv12. Not always, just some I saw.

This needs to replace SPP deblocking; it's quite slow, but so is SPP, and this looks a lot better.

WOW...
FrFun7 is "Spatio-temporal Smoothers", but FrFun3b is only "Spatial Smoothers"

I know, becose need more memory for internal cache (I use SetMemoryMax)

i.e. may be good idea use "motion compensation" for better cleaning

PS and not filtred fist and last frames

Well if combined with RemoveNoiceMC, it does a nice job (on anime at least. didn't try on films yet)

Right, I should add this info to the readme asap... ^^;

Hehe, have you also compared the speed?

Could be surprising...

Thanks for v7!

Combined like:

AviSource("some.file")
DeGrainMedian(mode=2)
FrFun7(1.1,2.5,1.5)

give amazing results with my analog TV captures. Fine Detail is still there, massive amounts of noise gone, and still fast enough.

And the sharpening is not always needed when used at low thresholds.

As corrected by the author, it's still a spatial smoother, as there is no temporal denoising.

My conclusions:
1) The first and last frame wont get processed
2) optimization for multisequencing fft3dGPU and hard CPU filters
(I receive increased temporal radius)
3) for "my very hard cleaner script" need more memory then I have
(then increased temporal radius need more memory for internal cache)

I have thought that ver7 use previous and next frames

PS Excuse me my very bad English

[AEtH]

Awesome work!

@Soulhunter
Is there any chance to process first and last frames?

Will be fixed in the next rev, same goes for the mod8 thing... ^^

Really Nice Filter but damn slow.

Though was just fooling around with this & LSF in my script.

FrFun7(1.1,2.5,1.5)
LimitedSharpenFaster(smode=4)


Speed in CCE was 0.21 & a sample of 1000 frames was 7.96mb

Now i used this script of LSf with Soothe
dull = last
sharp = dull.LimitedSharpenFaster(smode=4)
FrFun7(1.1,2.5,1.5)
Soothe( sharp, dull, 24)

Speed in CCE jumped to 0.44 & sample was 7.7mb in size.

Quality wise not much difference in both the clips.

Using Frfun7 only also gave a speed of 0.22 so what makes it go faster with Soothe and placed as it is in the script.
