Ingaba ndiya kulahlekelwa umgangatho wesandi xa ndisuka kwi-MP4 ukuya kwi-MP2?

Ukuya kwi-lossy → ayilahleki akuzukubuyisela iinkcukacha ezisele zilahlekile.

Ndingayikhupha i-audio kwiifayili ezininzi MP4 kwi MP2 kwiqela elinye?

Iifayile ezininzi kumsebenzi omnye zifuna inkqubo ehlawulweyo. Ukusetyenziswa okukhululekileyo yifayile enye ngoguqulelo, uguqulelo olunye ngeyure. Kwinkqubo ehlawulweyo ungadibanisa iifayile ezininzi kumsebenzi omnye, emva koko ulayishe impumelelo nganye kwiyo okanye zonke kwi ZIP enye.

Ithatha ixesha elingakanani ukutsala i-MP2 yesandi ukusuka kwi-MP4 yeyure?

Oku kuxhomekeke kubungakanani nobude befayile. Amaxwebhu amancinci kunye nemifanekiso ihlala ilungile ngokukhawuleza. Iividiyo ezide zithatha ixesha elide, kuba iinguqulelo ezininzi zevidiyo ziphinde zikhowudi iframe nganye.

Ndingayikhupha icala le-MP4 yesandi njenge-MP2?

Akukho kule sixhobo ngokuthe ngqo — khupha isandi esipheleleyo njenge MP2, emva koko sebenzisa /audio-trim/ okanye /audio-cutter/ ukucima icandelo. Umendo wenyathelo elinye uhlala ukhawuleza kunenkqubo edityanisweyo kwaye ukunika ulawulo oluchanekileyo lwenqanaba le-waveform.

Ingaba ifayili yam MP4 ifihlakeleyo ngexesha lokukhupha isandi?

Ewe. Iifayile ezilayishwe phezulu ze MP4 ziqhubekekiswa kwiseva yethu yokuguqula, akukho mntu ujonge phezulu, kwaye azisasazwanga. Ukukhuphela kunye nokuguqulwa kwe MP2 kususwa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa, oshiya ixesha lokulayisha ezantsi iziphumo. Bona /privacy/ kwinkqubo epheleleyo.
