Dnr Yv12 ?

[AllTimeSToneD]

I have looking for a DNR filter for the YV12 format and couldnt find any :( and now i was hoping that a dev with a bit freetime (really hard these days :D ) could port the DNR2 YUV2 version of kiraru.

TIA ^_^ and take your time

I second that pledge.

If any programmer were so kind to supply us with a yv12 version of DNR, his work would be greatly appreciated. :)

Looks like an YV12 version has been released for both DNR2 and 2DCleaner...

Great! I will try it asap, but right now I´m busy with another encode.
BTW: Did somebody find kiraru`s e-mail on his HP? I would like to thank him personally for this neat Christmas present :)

DNR2 is indeed fully YV12 compatible now, as it seems, but the 2dcleaner still works in YUY2, according to the readme. Both should be compatible with Avisynth 2.5 now.

Oh - and there is a new coloryuy2 - damn - another 500 new parameters I have to reverse engineer ;)

Can anyone (with the proper language skills) see what "interpolate" does? The code is very good, but rather hard to read ;)

It looks to me like it makes the chroma in column 2 the average of columns 0 and 4, the chroma in column 6 the average of columns 4 and 8, and the chroma in column 10 the average of columns 8 and 12, etc.

That would mean that only every other column of chroma in YUY2 is smoothed, leaving every other one untouched. ptr += 8; looks like that much of a jump to me, since there is one sample of u and one of v in every four bytes of the YUY2 color space.

I am not sure if I am being clear, but that is as good as I can make it now.
