MOV ukuba M4A Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani i-audio kwifayili yam MOV njenge M4A?

Layisha phezulu ifayili MOV kwaye umguquli ukhupha umsinga wesandi, emva koko uguqula ukukhowuda ku M4A. Akukho sibini sevidiyo esidlulayo - umkhondo obonakalayo ulahliwe ngokukhawuleza ngoko ke ukutywina kukhawuleza kakhulu kune-re-encoding epheleleyo. MOV yi Apple QuickTime isiqulathi seefayili, ethunyelwe ngo-1991 kwaye ihlala ifomati iPhone, iPad okanye Final Cut Pro umgca wexesha ubhala ngokumiselweyo. I-M4A yi-MP4 equlethe i-audio kuphela, kwaye yiyo into eyenza i-iTunes, i-Apple Music kunye ne-iPhone Voice Memos app.

Ingaba ukutshintsha MOV ukuya ku M4A kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i M4A encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu isiphumo sihlala sicacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i M4A ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-MOV ihlala ihambisa i-H.264 okanye i-HEVC yokuhambisa, okanye i-ProRes xa i-master edityaniswe, kunye ne-AAC okanye i-PCM engenakucothayo. I-M4A igcina i-AAC kwiziganeko ezininzi, okanye i-Apple Lossless (ALAC) xa ivela kwi-rip engalahlekiyo.

Ndingayiphawula i M4A ngeenkcukacha zomculi ne-albham?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe MOV, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. M4A ithatha isihloko, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. I-M4A igcina i-data ye-meta eninzi ye-iTunes-style, izihloko kunye nomsebenzi womzobi okhuselekileyo, kwaye yifomati yesandi esemthethweni kwisixhobo se-Apple.

I-M4A ekhutshiweyo isebenzisa i-bitrate yesandi eyiphi?

Ixabiso le-bit elimiselweyo le-lossy M4A yi-192 kbps, ebonisa ngaphaya iingoma. Ungayicima i-320 kbps (audiophile) okanye i-96-128 kbps (ulizwi / ipodcast / ifayili encinci). Ixabiso le-bit eliphantsi livela kukhetho oluphambili phambi kokuba ucofe uguqule.

Ingaba ndiya kulahlekelwa umgangatho wesandi xa ndisuka kwi MOV ukuya kwi M4A?

Ukuba M4A ayilahleki (WAV, FLAC), yonke isampuli igcinwa ngokuchanekileyo. Ukuba M4A ilahlekile (MP3, AAC, OGG, Opus), i M4A codec iphinde icinezele umbhalo ovela kumbhalo - kwi-192 kbps isiphumo sicacile kuzo zonke izinto eziqukayo. Ukuya olungalahleki → olungalahleki akuyi kubuyisela inkcukacha esele zilahlekile.

Ingaba i-M4A yesandi igcina umyinge wesikhokelo ongaphambili?

Ngokungagqibekanga ewe — 48 kHz yesandi kwi MOV yakho ihlala 48 kHz kwi M4A imveliso. Ukukhupha i-CD okanye ukulungelelanisa umdlali ovela kwixesha elidlulileyo ungakhupha isampuli ukuya kwi-44.1 kHz ngesampula-yexabiso eliphantsi; isampuli ephindaphindwayo iphezulu kwi-SoX-grade.

Ndingayikhupha isandi ukusuka kwiifayili ezininzi MOV ukuya kwi M4A kwiqela elinye?

Ewe - shiya isiqulathi seefayili se MOV iifayili kwaye sikhuphe umsindo ngokuthe tye. Abasebenzisi abaphezulu bafumana abasebenza ngokuthe tye abaninzi; kwifayile ye-50 iqela lento le yinto eyahlukileyo phakathi kwemizuzu emibini kunye nemizuzu elishumi elinesibini.

Ingaba i M4A izakuphawulwa ngesihloko / umculi / i-metadata ye-albham?

Ukuba i MOV ithatha isithuba okanye i-metadata yokuhamba, sikopa isihloko / umculi / i-albham yemihlaba kwi M4A isiqwenga. Ukuba akunjalo, i M4A iza ngaphandle ingaphawulwanga - sebenzisa umhleli wephetshana elichazayo (Mp3tag, Picard) emva korhwebo ngaphandle lophawulo oluninzi.

Ithatha ixesha elingakanani ukutsala i-M4A yesandi ukusuka kwi-1-iyure i-MOV?

I-audio demux + encoding ikhawuleza - iqhelekileyo 5 ukuya kwi 15% yobude bomthombo. I 1- iyure MOV → M4A igqiba kwi 3 ukuya kwi 9 imizuzwana kwindlela eqhelekileyo yokuhambisa; Uthelekiso oluphezulu lukhupha oku ngaphezulu kwimisebenzi yeqela.

Ndingayikhupha icala le-MOV lesandi njenge-M4A?

Ayikho kule sixhobo ngokuthe ngqo — khupha isandi esipheleleyo njenge M4A, emva koko sebenzisa /audio-trim/ okanye /audio-cutter/ ukucima icandelo. Umendo wenyathelo elinye uhlala ukhawuleza kunenkqubo edityanisweyo kwaye unika ulawulo oluchanekileyo lwe-waveform-level.

Ingaba ifayili yam MOV ifihlakele ngexesha lokukhupha isandi?

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngalinye: abaqeshi ababekwe ngokukodwa, akukho kuhlaziyo lomuntu, ukucinywa okuzenzekelayo ngaphakathi kwemizuzu yokuphela. Ifestile yokugcina epheleleyo ikwi /privacy/.

Kutheni le nto ifayili M4A isebenzisa izithuba ezizinyamalalayo apho i MOV isebenzisa khona isandi?

I-%s ifuna ukhetho olungalunganga lokuhamba-phakathi: MOV iqulethe iingoma ezininzi zesandi kwaye i-demuxer ithathe umsinga ongenanto okanye oncedisayo. Sebenzisa umkhethi ophambili "wokuhamba-phakathi kwesandi" ukukhetha umsinga 0, 1, 2 ngokucacileyo, okanye ubeke injongo kwi M4A isiqulathi seefayili esixhasa ukuphuma kweengoma ezininzi (FLAC, OGG).

MOV

I-MOV yifomathi ye-QuickTime ka-Apple, exhasa ividiyo kunye nesandi esikumgangatho ophezulu sokuhlela ngobuchwephesha.

M4A

I-M4A yifomati yefayile yomsindo esondeleleneyo neMP4. Ibonelela ngoxinzelelo oluphezulu lweaudio ngenkxaso yemetadata, iyenza ilungele usetyenziso olwahlukeneyo.
