Dfftest so slow.

[Samuru21]

Is there a faster alternative that gives the same results. Converting a 30 sec clip to lossless takes 20 to 30 minutes!

Dfttest not dfftest

[mirkosp]

Could try to use fft3dgpu, but then again it'd help only if you have a good gpu...
Otherwise, for the same results, you'd hardly find anything as good, with better speed. Perhaps vaguedenoiser could be an alternative. Can sometimes be better than fft3d, but is always faster.
I'm not entirely sure how the speed of fft3d compares to dfttest, but IIRC it's about the same speed if not slower.

alright... thanks

What else is in the script?

Be aware that sometimes script rendering times can multiply themselves inexplicably based on which filters are being run and how they operate on the frames in a video.

For example, DFMDeRainbow and LUTDeRainbow perform different forms of derainbowing, and together can knock out practically all the rainbows from the sources I've tried them on (the original AnimEigo release of the Oh My Goddess! OVA, for example - egregiously bad rainbowing, but that combo gets rid of something like 99% of them). Separately, they can get the job done in a matter of maybe 10-20 minutes each (my comp is really old), but having both activated in the same script will usually inflate the conversion time to over an hour.

Ok, so there's one resizer, two correction filters, an anti-aliaser, 3 smoothers, and 2 sharpeners/masks. And that deen line is pathetically weak. I doubt it even does anything noticeable at those settings.

Doesn't Sangnom have a reputation of being a slow filter? I seem to remember so, but it's been a couple years since I toyed around with it.

[mirkosp]

Sangnom is also a pretty bad antialiaser (if just called like that anyway)...
I think when it comes down to speed, daa is pretty much the best anti-aliasing choice, though maa still is the best antialiaser choice overall.

[Samuru21]

Can't find anything on daa and maa? mind giving me a download link to these plug ins

[Qyot27]

daa() is part of AnimeIVTC; I would assume maa() is as well, since it's mentioned in AnimeIVTC's release post on doom9.

So, in other words, if you've got the latest AMVapp, you already have them, as the AMVapp includes AnimeIVTC, if I remember correctly.
