Umfanekiso uya kuba yintoni ukuba ndibeka i-AAC yesandi kwi-MP4 ifayili?

Ukhetha oku, kuba isandi kuphela asikho umfanekiso. Okungagqibekanga kukubonisa i waveform eqinileyo, kwaye unganikezela umfanekiso oqinileyo endaweni - ubugcisa besiqhoboshelo, ikhadi lesihloko, umfanekiso - ogcinwa ixesha elipheleleyo. Oku kwenza ifayile ilayishwe phezulu kwividiyo kuphela iiplatforms ezingamkeli umkhondo wesandi omnyama. I-MP4 yindawo ekhuselekileyo yokunikezelwa kweenkqubo ezifumanekayo - yonke ifowuni, ibrowser, i-console, umhleli kunye neSmart TV eyenziwe kwiminyaka elishumi edlulileyo idlala ngaphandle kwesoftware engaphezulu.

Zonke izinto - inani lengoma, i-albham, unyaka, uhlobo - ayikho indawo elinganayo kwifayili yevidiyo kwaye ilahliwe endaweni yokuqikelelwa.

Ingaba umxube we-surround kwi-AAC uya kuqhubeka ujikeleza ngaphakathi kwe-MP4?

Ewe — MP4 ihambisa umjelo oninzi wesandi ngokuchanekileyo, ngoko ke umxube we-5.1 uhlala u-5.1 nobeko lwesiqhagamshelanisi olungenanto ngaphandle kokujika kwi-stereo. Oku kubaluleke ukuba ifayile imiselwe kumxhasi we-cinema yasekhitshini ngaphandle kocingo, oza kudibanisa phantsi ngexesha lokudlala nakuphi na. I-MP4 eninzi eluhlaza yi-H.264 yevidiyo enesandi se-AAC; isiqulathi sigcina ngokusemthethweni i-HEVC, i-AV1 ne-VP9.

Ingaba i-AAC ukuya kwi-MP4 ikhululekile?

Ewe - uguqulelo olusisiseko AAC → MP4 lukhululekile ngaphandle kobhaliso olufunekayo. I-Premium idibanisa umda ophezulu wobungakanani befayili nganye, abasebenzi abangaphezulu beqela elifanayo, ulondolozo olude, kwaye isusa ii-ad.

Ingaba i AAC ifile ikhulu kangakanani na ndiyiguqule ibe yi MP4?

Uguqulelo lugcina yonke inkcukacha enokuthi i AAC ne MP4 ziyibonakalise. Iimpawu ezikhethekileyo zefomati ezingokubonisa i MP4 (umzekelo, i-vector data kwimveliso ye-raster, iifomula kwimveliso yombhalo ocacileyo) ziyenziwa ibe yi-raster okanye zitywinwe — iphepha leziphumo libonisa into etshintshiweyo. I-AAC ilahlekile kodwa isebenza kakuhle kune-MP3, kwaye iphatha ukuya kuthi ga kwi-48 yeendlela eziqhelekileyo kunokuba ifakwe ibhotile kuyilo lwestereo.

Ndingaguqula iifayile ezininzi AAC zibe MP4 ngaxeshanye?

Ewe — susa iifayile ezininzi AAC kummandla wokulayisha kwaye zifololwe ngokuthe tye. I-Premium iqhuba abasebenzi abathe tye abaninzi; kwi-50-file batch le yi-difference phakathi kwemizuzu nemizuzu.
