breve
A five-star bake. Worth schmearing, sharing, saving.
Summary
The AV1 Image File Format (AVIF) specification has been updated to version 1.2.0, introducing support for sample transforms. This enhancement allows files encoded with bit depth extensions to maintain backward compatibility with legacy implementations while enabling full 16-bit precision (or more) with newer decoders. The update represents a technical advancement in image compression technology.
Key quotes
· 3 pulledThe files encoded with a bit depth extension relying on Sample Transforms are backward-compatible in the sense that they can be decoded for up to 12-bit precision by legacy implementations.
They can also deliver the full 16-bit precision (or more!) with newer implementations.
