The result is no "banding" in the sky, no macroblocking in shadows, and a stable grain structure that preserves the cinematic look of the ARRI Alexa 65 cameras used to shoot the film.

X265 is the successor to X264. It is a high-efficiency video codec that compresses the massive 4K data into a manageable file size without visually losing quality. It is why a 60GB disc can be reduced to a 15-20GB file while retaining 99% of the visual fidelity. Proper feature: “On-screen HDR metadata inspector + tone

Released in 2018, Free Solo follows rock climber Alex Honnold as he prepares to become the first person to climb El Capitan’s 3,200-foot vertical rock face in Yosemite National Park without ropes.
