Layisha phezulu ihele MOV futhi umguquli ususa umsindo osuka kwi-MOV, bese uguqula ikhodi ibe yi-Opus. Amafreyimu wevidiyo asuswa — akukho sikhathi sevidiyo sesibili, akukho phutha lomgangatho ngaphandle kokukhishwa kwe-Opus codec. MOV Apple's QuickTime isitsha, ethunyelwe ngo-1991 futhi akazange ashintshe ifomu iPhone, iPad noma Final Cut Pro timeline ubhala ngokuzenzakalela.
