M4V kuya AUDIO Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani i-audio track kusuka ku-M4V njenge-AUDIO?

Layisha phezulu ihele M4V futhi umguquli ususa umsindo osuka kwi-M4V, bese uguqula ikhodi ibe yi-AUDIO. Amafreyimu wevidiyo asuswa — akukho sikhathi sevidiyo sesibili, akukho phutha lomgangatho ngaphandle kokukhishwa kwe-AUDIO codec. M4V Apple's uhlobo MP4, esetshenziswa iTunes kanye Apple TV app for movies kanye TV iziqephu. Umsindo lapha yinjongo ejwayelekile: umguquli ukhipha umsindo futhi ukhetha ukukopela okudlalwa ngokubanzi.

Ingabe ukushintsha M4V kuya ku AUDIO kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-AUDIO encoder isebenza kusuka kumsindo osele udlulele engxenyeni eyodwa ye-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une-lossless master nganoma yikuphi, uku-encoding i-AUDIO kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele. Ukuthuthukiswa M4V MP4 - H.264 noma HEVC nge AAC - nge optional Apple FairPlay DRM ne iTunes isiqephu metadata. Iphutha lokuphuma ku MP3 ku 192 kbps, okucacile kumathuluzi amaningi futhi okufundeka nganoma iyiphi idivayisi.

Ingabe ngiyiphawula i AUDIO ngemininingwane yomuntu odlalayo ne-album?

Yebo, futhi kuyinzuzo engokoqobo ngaphezulu kwe M4V, engeke ikwazi ukugcinwa kuphi naphi. AUDIO ifaka isihloko, umculi, i-album, unyaka, inani le-track kanye ne-cover art efakwe ngaphakathi kwebhokisi, ngakho-ke i-library yomculo ifaka ngokulungile ngaphandle kokufaka isandla. Ukukhetha isiphetho ngokuzenzakalela kuyindlela ekhawulezayo uma konke ofunayo wusandi ngaphandle kwehele, ngaphandle kwesinqumo se-codec esidinga ukukwenziwa.

Yini ekwenzeke kumsindo othile uma uguqula M4V ku AUDIO?

Ihlolwe phansi ku-stereo, ngoba AUDIO ayinayo indlela esebenzayo ye-multichannel. Ukuxuba okuphansi kusetshenziswa izilinganiso ezijwayelekile ukuze umhlangano we-channel ephakathi uhlale ucacile futhi izingqimba zixhunywe ku-level ephansi. Noma yini esekelwe ekubekeni kwe-channel ehlukile idlule lapho lokhu kwenzeke. Okuzenzakalelayo ku-lossy, ngakho uma umsuka ube yi-lossless futhi ufuna ukuhlela noma ukuphatha, buza nge-WAV noma i-FLAC ngokucacile.

Kungani ezinye ze M4V zefayela lami zingaguqulwa?

DRM. Iqoqo elincane lamafayela M4V libhalwe ngokufihlakele yisitolo noma isofthiwe eyenza, futhi umsindo obhalwe ngokufihlakele awukwazi ukukhishwa yinoma iyiphi i-convertor. Noma yini oyidingayo, orekhodiwe, noma othengiswe ngaphandle kokuvikelwa uguqulwa ngokuvamile; ukuthengiswa kwelayisense akuzokwenza. DRM-ikhuselwe M4V ukuthenga ngeke kushintshwe yinoma yini; kuphela M4V izithombe ezingakhuselwanga ziguqulwe, futhi abadlali Apple-ayikho njalo kufanele ubanzi kuthiwa.

Yiyiphi i-track yomsindo ekhishwayo uma M4V yami iqukethe eziningi?

Ngephutha umsindo 0 (umsindo wokuqala, ngokuvamile umsindo omkhulu). Uma M4V wakho ufaka umlayezo, ama-dubs, noma umsindo ochazayo kuma-tracks angeziwe, umkhethi othuthukisiwe "umsindo" ukuvumela ukuthi ukhethe 1, 2, 3... ngokucacile. Uhlu lwe-track lubonisa ukufinyelela kokubuka kuqala ukuze ungakhetha ngokuzifihla.

Ihele AUDIO lisebenzisa i-bitrate enjani?

Iphutha AUDIO i-bitrate yi-192 kbps (icacile kuma-earphones amaningi). Nciphisa ku-320 kbps nge-audiophile output, noma 96-128 kbps ngezwi/podcast lapho ihele elincane liyisisekelo. Ama-AUDIO angeke alahlekile (WAV, FLAC) agweme ukumiswa kwe-bitrate futhi agcine yonke isampula.

Ingabe ukusuka ku M4V kuya ku AUDIO kuzonciphisa ubunjani bomsindo wami?

Uma i AUDIO ifomethi ingekho lutho (WAV, FLAC, ALAC), yonke isampula yangempela igcinwa. Uma i AUDIO ingekho lutho (MP3, AAC, OGG, Opus), i-codec icindezela futhi — ku-192 kbps ushintsho alukwazi ukulizwa kuningi kwezithameli; ku-96 kbps ungalizwa ama-cymbals noma ama-sibilans abandayo. I-M4V i Container ayinaso isikhundla kulolu hlelo — ukumiswa kwe-codec kuphela okubalulekile.

Ingabe i-AUDIO ekhishwayo igcina i-M4V isilinganiso sesampula?

Ngokungagqibekanga yebo — 48 kHz M4V umsindo ushintsha ube 48 kHz AUDIO umsindo, 44.1 kHz ushintsha ube 44.1 kHz. Uma ufuna ukuncipha kwesampula ukuze kusebenze (isibonelo 96 kHz studio masters kuya ku 44.1 kHz CD-quality AUDIO) isampula-rate dropdown yenza lokhu ngekhwalithi ephezulu yokusatshalaliswa kabusha.

Ingabe ngingakwazi ukukhishwa kwe AUDIO umsindo kusuka kusibaya sehele M4V?

Yebo — susa isibaya se M4V amafayela endaweni yokulayisha futhi siqhube ukukhishwa ngokufanayo. I-Premium ithola abasebenzi abafanayo abaningi; ku-100-file batch (uhlelo lwemiculo-video olujwayelekile) lokhu kuyinto ehlukile phakathi kwamasekondi angama-90 namaminithi angama-8.

Ingabe kuthatha isikhathi esingakanani ukukhishwa kwe AUDIO kusuka ku-M4V wehora elilodwa?

Umsindo demux + transcode usebenza ngokushesha kakhulu kunakhodi yevidiyo - ngokuvamile 5-15% yesikhathi somthombo. Ihora le-1 M4V -> AUDIO liphele ngemizuzu engu-3-9 ku-pipeline ejwayelekile. Uma i-AUDIO codec ifana ne-source codec esekwi-M4V (ejwayelekile ye-AAC ngaphakathi kwe-MKV / MP4), iyi-remux ecacile futhi isebenza ngemizuzu.

Ingabe ihele AUDIO lifaka isihloko / umculi / amathegi we-albhamu?

Uma ihele M4V ligcina i-stream metadata (umculi, isihloko, i-album), sikopa lezi zindawo kuAUDIO isitoreji lapho ifomu lixhasa amathegi. ID3v2 (MP3), amazwana we-Vorbis (OGG, FLAC), ama-MP4 atoms (AAC / M4A), RIFF INFO (WAV) wonke abhalwe. Ukungabi nathegi M4V kwenza AUDIO — sebenzisa i-Mp3tag noma i-Picard emva-kwe-ukukhishwa ukuze uthuthukise.
