Does anyone know if there is an existing function for Avisynth that can be used to adjust the brightness of a specific vertical section of the frame?

One option that came to mind is to try using ColorYUV(off_y = XXX) on a specific part of the frame, but perhaps there is already a ready-made implementation for this?

I’ve attached a screenshot and a short AVI clip showing the problem I’m trying to fix.

I've been trying to restore this source, but the only problem is removing the heavy halo from this source

The best I got is this script which removes some of it, the heavy parts can still be seen:

Code:

LWLibavVideoSource("blah.ts")

AnimeIVTC(mode=1, omode=1)

vinverse2().vinverse2().vinverse2()

QTGMC(preset="Placebo", TR0=2, TR1=2, TR2=3, Rep0=1, Rep1=0, Rep2=5, EdiMode="EEDI3", InputType=3, NoiseRestore=1.0, NoiseProcess=1, Sigma=1.4, StabilizeNoise=True, ProgSADMask=25.0)

Crop(180, 0, -180, -0)

Debicubic(c=0.33, 720, 540)

HQDeringmod(mrad=6, nrmode=3, thr=255, darkthr=0)

DeHalo_alpha_mt(rx=1.4, ry=1.4, darkstr=0.0, brightstr=1.8, lowsens=20, highsens=75, ss=1.4)
