I heard that the original author(AviUtl version) is a professional who is working in an authoring studio as you.

flash3kyuu_deband in high precision mode has the job very well done, indeed. And it is fast. Congratulations to you and to the author of the original filter.
BTW, GradFun3 current default settings are a bit on the conservative side, therefore to get comparable results you should add mask=0 to your tests.

Thanks for your great work SAPikachu.
What abut YUY2 support? There seams to be quite a lot work going on around dithering/debanding. Is there a solution, which would dither 10bit (or higher) source to 8bit output? As far as I understand this tool is for debanding and designed to remove existing banding on 8bit sources. What about dithering eg. v210 source- can it do this?

Actually, the high precision mode will upsample pixels to 14bit first, and downsample to 8bit after processing. Dithering occurs in downsampling. The dither algorithm are well-known ones (Floyd-Steinberg dithering and Ordered dithering). But since AviSynth does not support higher bit-depth natively, it may be difficult to import the video source. If it can be loaded, it shouldn't be very hard to add support for it. |

There were some attemps to import v210 Qt into avisynth- not sure if it's working and compatible with your work.

I have used this filter in combination with MDegrain for several sources and I'm very happy with the results.
I also played around with the "diff_seed" parameter but can't really see any difference (apart from the fact that "diff_seed = true" is quite a bit slower). Do you have any more info on the usefulness of that parameter? |
