Formatul containerului define\u0219te structura fi\u0219ierului \u0219i ce tipuri de con\u021binut pot fi incluse, \u00een timp ce codecurile se ocup\u0103 de compresia \u0219i decompresia real\u0103 a fluxurilor audio \u0219i video din acel container.\n\nAceast\u0103 distinc\u021bie este crucial\u0103 atunci c\u00e2nd depana\u021bi problemele de redare.

C\u00e2nd \u00eenregistra\u021bi un videoclip pe telefon sau pe camer\u0103, materialul brut ar crea fi\u0219iere enorme – adesea sute de gigaocte\u021bi pentru doar c\u00e2teva minute de con\u021binut.
