QoMEX (Quality of Multimedia Experience) konverentsil esitatud loengutes tutvustatakse video kodeerimise formaadi AV2 testimise tulemusi, mille arendamisega tegeleb Open Media (AOMedia) liit ja mis asendab formaati AV1. Kasutades kvaliteedi hindamise metrikat VMAF (Video Multi-Method Assessment Fusion), mille on v\u00e4lja t\u00f6\u00f6tanud Netflix, v\u00f5imaldas AV2 kodeki kasutamine saavutada bitikiirusest 32,59% v\u00e4henemise v\u00f5rreldes AV1 kodekiga sarnase kvaliteedi juures. PSRN-YUV (Peak-Signal-to-Noise Ratio 14:1:1) metrikate kasutamisel \u00f5nnestus bitikiirus langetada 28,63%. Testimisel kasutati versiooni AVM 11.0 koos AV2 mudeli n\u00e4idisega.
