About This Article
Netflix had to figure out the best way to encode video in AV1 across thousands of titles at different resolutions and frame rates without losing the creative quality of the original content.
The Encoding Technologies team standardized on 10-bit depth encoding for all AV1 streams. They encoded at the highest source resolution and frame rate available, then used dynamic optimization to allocate bits intelligently at the shot level.
Netflix was able to encode their entire catalog efficiently while keeping visual quality high. The certification process also caught decoder capability gaps across TV manufacturers before the launch.
