[HELP] Capture from 1970s Umatic tape problem

Hybrid was only basic color grading support, so I would in general recommend to use i.e. DaVinci Resolve so the color grading there and export the grading as a LUT (.cube) and then use it in Hybrid through Filtering->Vapoursynth->Color->Matrix->TimeCube.

That said, Hybrid also comes with a bunch of LUTs, if you enable "Filtering->Vapoursynth->Color->Matrix->TimeCube->Custom LUT folder" and select the 'color'- folder (Hybrid\64bit\vsfilters\ColorFilter\TimeCube\color), maybe one of these already does what you aim for.

Additionally, you can use the filters under "Filtering->Vapoursynth->Color" especially Basic and Misc to do simple colro grading.
(side note: you might want to enable "Filtering->Vapoursynth->Misc->Preview->Histrogram" for the Vapoursynth Preview)

Ps.: one can also use custom code like the one below to lessen highlights:

## LESSEN HIGHLIGHTS clip = core.std.Expr(clip, expr=["x 200 > x 0.8 * 40 + x ?"]) # alll color plaes clip = core.std.Expr(clip, expr=["x 200 > x 0.8 * 40 + x ?","", ""]) # luma only
