Mario Joos on YouTube Thumbnails That Actually Get Clicks

​You spent months on your short film. The trailer is tight. The edit is clean. You upload it — and it gets 200 views. The problem isn't your film. It's your thumbnail.

​In a platform built on split-second decisions, your thumbnail is the single highest-leverage asset you control — and most indie filmmakers treat it like an afterthought.

​Mario Joos, editor forged in the Mr. Beast content machine, knows exactly what separates a thumbnail that gets ignored from one that pulls hundreds of thousands of clicks. In this 30-minute live workshop, he'll break down the design principles, A/B testing logic, and packaging strategies that make viewers choose your trailer over everything else in their feed.

​This session is part of the Future Vision XPRIZE — a $3.5M+ global competition challenging filmmakers to create 3-minute sci-fi trailers envisioning an optimistic future for humanity. Grand prize: $2.5M toward producing your film (up to $15M total budget via Range Media + Republic Film), plus $100K cash. Submissions close August 15, 2026.
