I've built a new filter to try out some new approaches to smoothing.

MipSmoother is an attempt at reinventing SmoothHiQ and Convolution3D. MipSmooth was made to enable smoothing of larger pixel areas than 3x3(x3), to remove blocks and smoothing out low-frequency noise.
It is my hope that this filter will be better than C3D at smoothing out flat surfaces and gradients. This should be good for cartoons/anime, but it actually also helps film footage quite nicely.

Get it at: http://cultact-server.novi.dk/kpo/av...MipSmooth.html

Requirements:
* YV12, RGB and YUY2 support.
* CPU capable of running Integer SSE code. (P3, Athlon and newer).
* AviSynth 2.5 required.
* AviSynth 2.5.2 recommended.

The new presets are fairly untested, and only based on a few sample clips, so I'd be happy to recieve feedback and propositions for changes.

Hi there,
Does SpaceDust has a version for 2.52, I can only see the version for AVI Synth 2.0x By the way, Do we need space dust in 2.52?

I just did a quick test, running ToK's sampler ( the second 10% sampler), and without the filter it took 42 seconds. Then I took away TemporalSoften(2,7,7,3,2) and added MipSmooth(preset = "movieHQ").
Now it took 1 minute to encode the same sample
Quality of both samples is almost identical, but encoding time is more that 25%

Maybe its worth trying another setting like
MipSmooth(preset = "movieLQ", scenechange = 8)

Well Kwag you right again try different settings
and eventhough with the default parameters file size is smaller and a bit faster
temporalSoften its still about 20 sec. faster, Quality its about the same i guess.

@jorel: Yes - that is the way to invoke the presets - should work just fine.

@kwag: It's a bit more complex than temporalsoften, so it will take more time. It should be able to give considerably better image quality than temporalsoften - mainly because it does spatial work. It should be compared to c3d.

I'm thinking about adding parameters to limit the number of mip (downsampled) frames that should be generated for each frame - also I'm looking in to possible cache techniques - so speedwise we are not out of options yet

@syk2c11: Use the LoadpluginEx dll (search here or at doom9 forums).

@all: I'm very interested in suggestions, and comments on the presets (too strong, too soft, artifacts, etc) - this is why it is still not 1.0 - it still needs a bit of finetuning.

But it's looking good, and looks like you're on the right track and this will be a winner soon
I'll play more with it

Superb filter. May be a little slow, but that doesn't bother me. Definitely works a lot better than Convolution 3d! I just use the movieHQ or LQ setting and it comes out great. Seems to be a lot less noise without adding a lot of blurring. I was getting worried about not finding a filter that was close to Convolution since the develpment has been stopped, but now comes mipsmooth!!

true digitalize,

i did some tests and got good results with movieHQ.
convolution is great and MipSmooth is better...little slow,
maybe sh0dan will improve some more speed, will be cool.

I just tested the filter yesterday, and something is going wrong I think... I tested it on a noisy full-screen 90 min. long Capture, and it took 15 hours to encode the movie at 480x576 resolution...
I'm on Athlon XP 1800+...
Is it really THAT slow or is something going wrong?

I use the MovieHQ settings listed in the html file that comes with the filter, but I change the upsize and downsize both to bicubic or lanczos. Looks almost identical to the original. Amazing. I use CCE, and it does seem extremely slow compared to other filters. Since CCE is so fast I can live with it. The speed is comparable to FaeryDust or PixieDust.

I have tried this filter again, and the results are simply amazing
The only problem is speed
Encoding speed is X5 slower (compared with the filters in the current script ), so right now, I would only use it on short films and on night runs
I hope sh0dan can optimize the filter

So what are your recommended settings kwag? where did you put it in the current script?`
I really don't care about time when it comes to quality, so please post your AVS script here...

5 Times Slower

Wouldn't that mean that a 5 Hour encode would be a 25 Hour encode???
