Selur's Little Message Board

I uploaded a new dev version which uses vs-nlm-ispc when "cpu" is selected.
Let me know if this version works for you.

Adding the CPU option = success.

Thanks Selar for sticking with this.

So my original premise of removing vertical banding even with KNLMeansCL, YAHO, and CAS settings still hasn't generated a "cure". But its great to be able to include this for my denoise filter now as I originally intended. I'll have to keep playing with the filters to address the vertical line issue. I'm leaning toward tuning LSFMod since it has targeting for edge sharpening. 
Attached is what I've begun with.

There's so many filters with so little time...

I don't really see color banding.
In your image, I see color bleeding and/or maybe some color shift.
(Might also be a chroma shift in the fields, but I can't from the current sample since it has not enough motion)
Try:
This does help a bit, which seems to be a chroma shift: https://imgsli.com/MzkxMTMz
It might also help to add aWarpSharp2 (on chroma only) after that.

Can you share a clip from the scene where your screenshot comes from, is visible in the video?

Ps.: Just noticed 'FixChromaBleeding' h&v controls are switched.

Ok try to get you some more samples source footage tomorrow or by Sunday. I may be tied up tomorrow. 

One thing i mentioned earlier to highlight is that it's on the source dv avi and a far as my best research tells me, I'm leaning towards a column-aligned artifacting or vertical patterning, or maybe some DCT-based artifacting due to camera limitations in the environment - and the filters are just accurately processing it.
