What is VMAF?
Imagine you're watching your favorite cartoon on TV. Sometimes it looks super clear, and other times it looks blurry, right? Well, there's this cool thing called VMAF—it's like a tool that rates how clear or fuzzy videos look.
Think of it like a team of tiny robot superheroes watching the video and giving it a score. If they give it a high score, like 93-95, it means the video looks really awesome and clear. In fact, for most people, it’s almost impossible to see any difference between the original and this super high-quality version.
