I made a post with a detailed line-by-line breakdown of the VHS shader I shared earlier. It was pretty helpful to me in the first place to understand and describe in layman's terms what each function does in the shader, in the same manner as I did before with the interactive grass shader in my blog.

I know that four texture samples for such a basic effect are less than optimal, but for the prototype it's okay for now. If you have any other ideas to optimize it, I'd be happy to hear them.

Also, thanks for sharing other great solutions in comments and DMs. Inspired by that, I have already started creating an improved version of my VHS effect and will post an update here once it is ready.
