MOV kuya AMR Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani i-audio track kusuka ku-MOV njenge-AMR?

Layisha phezulu ihele MOV futhi umguquli ususa umsindo osuka kwi-MOV, bese uguqula ikhodi ibe yi-AMR. Amafreyimu wevidiyo asuswa — akukho sikhathi sevidiyo sesibili, akukho phutha lomgangatho ngaphandle kokukhishwa kwe-AMR codec. MOV Apple's QuickTime isitsha, ethunyelwe ngo-1991 futhi akazange ashintshe ifomu iPhone, iPad noma Final Cut Pro timeline ubhala ngokuzenzakalela. I-AMR iyi-Adaptive Multi-Rate, i-codec yokukhuluma i-3GPP ejwayelekile yezingcingo zokukhuluma ze-GSM nezinhlelo zokurekhoda amagama ezimoto.

Ingabe ukushintsha MOV kuya ku AMR kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-AMR 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-AMR kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele. I-MOV ivame ukuthwala i-H.264 noma i-HEVC yokudlulisa, noma i-ProRes uma iyi-editor master, kanye ne-AAC noma umsindo we-PCM ongacindezelwa. I-AMR iyi-narrowband speech codec esebenza phakathi kuka-4.75 no-12.2 kbps, emodela i-human vocal tract endaweni yobubanzi obugcwele be-audio spectrum.

Yini ekwenzeke kumsindo othile uma uguqula MOV ku AMR?

Ihlolwe phansi ku-stereo, ngoba AMR 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. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okuphezulu kwe-frequency yefoni, futhi akukho inani lokuphindeka kokucofa liyibuyisela emuva.

Kungani umculo uzwakala ubuhlungu kulo mguquko?

Ngenxa yokuthi ingxenye eyodwa iyi-codec yokuxoxa hhayi i-codec yomculo. Imodelisa i-human vocal tract futhi isusa konke okungaphandle kwe-bandwidth yefoni, okulungile ku-voice memo futhi kulahlekile kunoma yini enezithuluzi ngaphakathi. Ukushintshana eduze kwayo akukwazi ukubuyisela izifremu ezilahlekile — azikhombisile endaweni yokuqala. Amafayela MOV akhulu, futhi ngaphandle kwe-Apple ecosystem ukusakazwa kosizo kuncane kuna-MP4 - ama-Android adala futhi amanye ama-Smart TVs azowayeka.

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

Ngephutha umsindo 0 (umsindo wokuqala, ngokuvamile umsindo omkhulu). Uma MOV 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 AMR lisebenzisa i-bitrate enjani?

Iphutha AMR 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-AMR angeke alahlekile (WAV, FLAC) agweme ukumiswa kwe-bitrate futhi agcine yonke isampula.

Ingabe ukusuka ku MOV kuya ku AMR kuzonciphisa ubunjani bomsindo wami?

Uma i AMR ifomethi ingekho lutho (WAV, FLAC, ALAC), yonke isampula yangempela igcinwa. Uma i AMR 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-MOV i Container ayinaso isikhundla kulolu hlelo — ukumiswa kwe-codec kuphela okubalulekile.

Ingabe i-AMR ekhishwayo igcina i-MOV isilinganiso sesampula?

Ngokungagqibekanga yebo — 48 kHz MOV umsindo ushintsha ube 48 kHz AMR 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 AMR) isampula-rate dropdown yenza lokhu ngekhwalithi ephezulu yokusatshalaliswa kabusha.

Ingabe ngingakwazi ukukhishwa kwe AMR umsindo kusuka kusibaya sehele MOV?

Yebo — susa isibaya se MOV 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 AMR kusuka ku-MOV wehora elilodwa?

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

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

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

Ingabe MOV yami imfihlo ngesikhathi sokukhipha umsindo?

Yebo — imodeli yobumfihlo efanayo nezo zonke iziguqulo. Umsuka MOV nesokudla AMR zicutshungulwa kubasebenzi abahlukanisiwe futhi zicishwe ngaphakathi kwemizuzu. Asikwazi ukudlala, ukugcina, noma ukuhlanganisa okuqukethwe. Bona /privacy/.

MOV

I-MOV iyifomethi ye-QuickTime ye-Apple, esekela ividiyo nomsindo wekhwalithi ephezulu wokuhlela kobungcweti.

AMR

I-AMR (I-Adaptive Multi-Rate) ifomethi yokuminyanisa yomsindo elungiselelwe ukubhalwa kwekhodi yenkulumo. Ivamise ukusetshenziswa kumakhalekhukhwini ukuqoshwa kwezwi nokudlalwa komsindo.
