Advanced VHS effect

[pepinderaisin (pépinderaisin)]

Hello , I made a VHS effect for my game but I think it doesn’t look realistic :

so I’d like to get something more realistic like that but I don’t know what more to add for this effect.

Colors, read some real information how VHS changed colors, and what it was bat with etc. I think you want realistic VHS effect, so you need real info about quality of that method.
