fixing chromableeding and halo

[jupiter82]

Here is short (13s and 48MB) sample: https://mega.nz/file/3NE1hB5A#914cPaeLM9OAoEPo-e9xtj8bFVdf6QvLToh_b_8lO-0

I have tried my own to fix it, but cant beat it. Maybe someone can help me?

There also seems to be some chroma shifting. (trying to shift the chroma back https://imgsli.com/MzM2MjQ1, you might want to tweak it)
Additionally, adding 1x_BleedOut_Compact_300k_net_g.pth and some (a bit too strong) denoising: https://pastebin.com/0nA4Snj3 (script: https://pastebin.com/0nA4Snj3)
jagabo might have some idea about the halo, iirc. he posted 'workable solution' for such strong halos a while ago.

Found your suggestion from other thread and used mlrt_ncnn(network_path="1x_BleedOut_Compact_300k_n et_g.onnx") which toned down the chromableed a lot. Chromashifting is indeed also a issue.

Make sure to first adjust the shift and then adjust BleedOut.

Something like:

LWLibavVideoSource("intermediate.demuxed.mpeg")  # or other source filter
QTGMC() # or other deinterlacer
MergeChroma(last, BilinearResize(width/2, height).aWarpSharp2(depth=25).nnedi3_rpow2(2, cshift="SPline36Resize", fwidth=width, fheight=height))
ChromaShiftSP(x=2, y=2)

ChromaShiftSP is 32bit only?

[Selur]

No, ChromaShiftSP is just a wrapper script using normal resizing and MergeChroma, so nothing that isn't part of Avisynth core:

function ChromaShiftSP (clip clp, float "X",float "Y") {

  X = default(X, 0.0) # positive values shift the chroma to left, negative values to right
  Y = default(Y, 0.0) # positive values shift the chroma upwards, negative values downwards

  w = clp.Width()
  h = clp.Height()

  clp.MergeChroma(clp.Spline16Resize(w, h, X, Y, w+X, h+Y))
}

Same in the Vapoursynth port.
