AVIF in sintesi
AVIF
AVIF emerged from the Alliance for Open Media's work around AV1 and uses the HEIF family as its structural container, which connects it to both modern web delivery and newer image-container design.
MEF in sintesi
MEF
Digital photography fragmented into many manufacturer-specific raw formats because camera makers optimized for their own sensors, metadata, and software ecosystems rather than for one shared public raw standard.
