Shadowy outline along black lines?

[killerteengohan]

I have this Blu-Ray and alot of the black lines seem to have blurry shadows along the outsides of the lines. Its very visible on white areas for sure.

I have already tried chroma sharpening and halo removal. It did not seem to fix it for me.

Whats with this and can I reduce visibility or remove them?

Here is a screenshot of what I am talking about.

Looks like 2 generations of oversharpening halos. The first generation creates bright edges around dark lines. The second generation exacerbates those bright edges and creates dark edges around them. You won't like the fix and it won't be perfect. Try Blur() with a small values like 0.2 twice in row. Maybe try masking it to only areas near black lines, but not on the black lines.

2 generations eh? I wonder how they accomplished that.

Thanks for the bit of input you had. I will try out the blurring or maybe increase dehalo alpha since it blurs as it gets set higher.

They probably ran an edge sharpener and a sharpening resize.

Maybe something like:

ImageSource("UWu9jbb.png") 
ConvertToYV12()
src=last

bl = Blur(0.5).Blur(0.5).ColorYUV(gain_y=5)

inner = mt_binarize(120).mt_inpand(chroma="-128")
outer = mt_binarize(120).Invert().mt_expand().mt_expand(chroma="-128")
mask = Overlay(inner, outer, mode="multiply").Blur(1.0)

Overlay(last, bl, mask=mask)

Interleave(src, last, mask)
