[HELP] How to fix bad colour bleed on VHS clips

[Selur]

Here's an idea to address the chroma mess: (no denoising&co)

# Chroma adjustment using ChromaShiftSP
clip = chromashift.ChromaShiftSP(clip=clip, X=10.00)
# Deinterlacing using QTGMC
clip = havsfunc.QTGMC(Input=clip, Preset="Fast", TFF=False, opencl=True)# new fps: 50
# Making sure content is preceived as frame based
clip = core.std.SetFrameProps(clip=clip, _FieldBased=0)# progressive
# sharpening using AWarpSharp2
clip = core.warp.AWarpSharp2(clip=clip, thresh=255, blur=2, depth=64, chroma=True, planes=[1,2])
# Fix bright and dark line artifacts near the border of an image using BalanceBorders
clip = havsfunc.bbmod(c=clip,cLeft=0,cTop=0,cRight=32,cBottom=0)

(moved ChromaShiftSP above the Deinterlacing, add AWartSharp2 on Chroma only, add BalanceBorders to hide the shifted chroma on the right)

Shifted:

+ BasicVSR++ only on chroma:

Ps.: Maybe move the chroma a bit more,..
