Ii-frames zevidiyo zilahliwe — akukho xesha lesibini lokudlulisa ividiyo, akukho lahlekelwa komgangatho ngaphezulu kwento ekhoyo kwi-AUDIO codec. I-MP4 yi-ISO/IEC 14496-14, imiselwe ngo-2001 kwaye ivela kwibhokisi yobeko lwe-QuickTime efanayo ne-MOV esetyenziswa.

Nantoni na exhomekeke kukubeka isiqhagamshelanisi esikhethekileyo iphela xa oku kwenzeka. Okumiselweyo kulahleko, ngoko ukuba umthombo wawungenalahleko kwaye ufuna ukuhlela okanye ukuphatha, buza i-WAV okanye i-FLAC ngokucacileyo.
