Nws suav nrog cov yam ntxwv ntawm MPEG-1 thiab MPEG-2 nrog cov thev naus laus zis tshiab hauv kev lag luam thiab cov yam ntxwv xws li Virtual Reality Modeling Language (VRML), 3D rendering, object-oriented composite files thiab txhawb cov qauv rau kev tswj hwm cov cai sab nraud. Nws tau pib ua tus qauv rau kev sib txuas lus video me ntsis, tab sis tom qab ntawd tau hloov mus rau hauv cov txheej txheem multimedia coding. MPEG tseem yog tus qauv tsim.
MPEG-4 Ntu 2 piav qhia txog qhov pom kev thiab tsim lub hauv paus ntawm Advanced Simple Profile siv los ntawm codecs kev koom ua ke rau hauv software xws li DivX, Xvid, Nero Digital, thiab 3ivx thiab los ntawm QuickTime 6. MPEG-4 Part 10 piav qhia txog kev yees duab ntawm tus qauv. MPEG-4 AVC/H.264 lossis Advanced Video Coding siv nyob rau hauv x264 encoder, Nero Digital AVC, thiab HD video tawm zoo li Blu-duab tshav Disc yog raws li qhov no. Hauv qab no yog cov ntsiab lus ntawm cov khoom suav nrog hauv cov qauv tshwj xeeb.
