 Abstract: This document specifies syntax and semantics for the storage of [[!AV1]] images in the generic image file format [[!HEIF]], which is based on [[!ISOBMFF]]. While [[!HEIF]] defines general requirements, this document also specifies additional constraints to ensure higher interoperability between writers and readers when [[!HEIF]] is used with [[!AV1]] images. These constraints are based on constraints defined in the Multi-Image Application Format [[!MIAF]] and are grouped into profiles inspired by the profiles defined in [[!MIAF]].
