MP4 w skrocie
MP4
MP4 grew out of the MPEG-4 and ISO Base Media File Format lineage, which helped make it both standards-based and commercially pervasive.
MEF w skrocie
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.
