Come risultato della codifica lo standard M-PEG2 offre differenti &quot;Profili&quot;. Ciascun Profilo è caratterizzato da un set di strumenti di compressione i quali caratterizzano il sistema di codifica. I profili sono cinque (Simple Profile, Main Profile, SNR Scalable Profile, Spatially Scalable e High Profile) e ciascuno di essi è progressivamente più sofisticato e aggiunge degli strumenti di compressione al precedente. </li></ul>
