Honestly, you can’t avoid gate weave and you can’t avoid grain if you’re doing things optically, so just decide how high of a budget your project is supposed to have and go for it. (Higher budget = less grain and less gate weave.)
This is 80’s-themed, but it has a lot of good insight into the workflow (and links to full tutorials) on how the Stranger Things titles were done: https://maxonvfx.com/4vLAtNq
I made this piece for Maxon with optical concepts in mind. Even though I used modern tools like 3D Stroke from Red Giant, things are off-center, there are artifacts from the scraping process, and more little imperfections to hint at the analog-ness of the era. (Though, I did cheat and pick a stylized color for the fading of the titles instead of an optically accurate one.) Unfortunately, some of my work really gets lost in the re-encoding that social media platforms use.
On that piece, I made it thinking about how they would have made the original piece. A tinted piece of plastic with black coating scraped off. So, I made the initial design with some brush imperfections, set it ever so slight off center, and set it spinning with some motion blur. Then, I exposed the titles over top of it (with a slightly different gate weave).
But, seriously, my little thing is nothing compared to the love that went into the Stranger Things titles. Highly recommend watching everything linked from the article on the Making Of.
