MOV ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani kuphela i-audio track ukusuka kwi MOV njenge AMR?

Layisha phezulu ifayili MOV kwaye umguquli ukhupha umsinga wesandi ukusuka kwisiqulathi seefayili MOV, emva koko uguqula ikhowudi ibe yi AMR. Ii-frames zevidiyo zilahliwe — akukho xesha lesibini lokudlulisa ividiyo, akukho lahlekelwa komgangatho ngaphezulu kwento ekhoyo kwi-AMR codec. MOV yi Apple QuickTime isiqulathi seefayili, ethunyelwe ngo-1991 kwaye ihlala ifomati iPhone, iPad okanye Final Cut Pro umgca wexesha ubhala ngokumiselweyo. I-AMR yi-Adaptive Multi-Rate, i-codec yokuthetha ye-3GPP emiselwe kwi-GSM yezingxoxo zelizwi kunye nezixhobo zokurekhoda ilizwi elihambayo.

Ingaba ukutshintsha MOV ukuya ku AMR kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i AMR 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 AMR 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-editor master, ecaleni kwe-AAC okanye i-PCM engenakucothayo. I-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, imodelisa umjelo wokuthetha womntu kunokuba iqulethe i-audio spectrum.

Ithini into ebangela ukuba i-multichannel yesandi iguqulwe kwi MOV ukuya kwi AMR?

Ijika ezantsi kwi-stereo, kuba AMR ayinayo indlela esebenzayo ye-multichannel. Ukudibanisa ezantsi kusetyenziswa izilinganisi eziqhelekileyo ukuze unxibelelwano lwe-center-channel luhlale lucacileyo kwaye izijikelezi-ndawo zidityanisiwe kwinqanaba eliphantsi. Nantoni na exhomekeke kukubeka isiqhagamshelanisi esikhethekileyo iphela xa oku kwenzeka. I-AMR ibulala umculo: ububanzi besantya sayo esiyi-8 kHz bususa konke okungaphezulu kwesantya sefowuni, kwaye akukho xabiso lokucofa kwakhona olungayibuyisela.

Kutheni umculo uthetha ntoni xa uguqulwa?

Kuba enye icala liyi codec yokuthetha kune codec yengoma. Imodelisa umjelo wokuthetha womntu kwaye ishiya konke ngaphandle kwe bandwidth yefowuni, elungileyo kwimemo yokuthetha kwaye ilahlekile nantoni na enezixhobo kuyo. Ukutshintsha kude nayo akuyi kubuyisela uxinzelelo olulahlekileyo - akufuneki kubekho ukuvulwa kwindawo yokuqala. Iifayile ze-MOV zikhulu, kwaye ngaphandle kwenkqubo yokudlala ye-Apple ecosystem inkxaso ingaphezulu kwe-MP4 — i-Android edala i-Android edala kwaye ezinye iiTV eziSmart ziya kuzinyamezela.

Ingoma yesandi eyiphi ephumayo xa MOV yam iqulethe ezininzi?

Ngokungagqibekanga umsinga 0 (umkhondo wokuqala wesandi, ngokuqhelekileyo umxube omkhulu). Ukuba i-MOV yakho ithatha iinkcazelo, i-dubs, okanye i-audio echazayo kwiimvavanyo ezongezelelweyo, umkhethi ophambili "umsinga wesandi" ukuvumela ukuba ukhethe 1, 2, 3... ngokucacileyo. Uluhlu lwemikhondo luboniswe kwimboniso yokukhuphela ukuze ungakhetha ngokuzifihla.

I-AMR ifayili isebenzisa i-bitrate enjani?

I-AMR emiselweyo ye-bitrate yi-192 kbps (ibonisa ngaphaya kwengoma kwiimvakalelo ezininzi). Nciphisa kwi-320 kbps yemveliso yeaudiophile, okanye 96-128 kbps yelizwi/ipodcast apho ifayili encinci iphambili. Iinjongo ezingalahlekiyo AMR (WAV, FLAC) zingahoyi isicwangciso se-bitrate kwaye zigcine zonke iiseti.

Ingaba ukutshintsha ukusuka ku MOV ukuya ku AMR kuya kunyusa ubunjani besandi sam?

Ukuba i AMR ifomati ayilahleki (WAV, FLAC, ALAC), yonke isampuli ebhaliweyo igcinwa. Ukuba i AMR ilahlekile (MP3, AAC, OGG, Opus), i-codec iphinda icinezele - kwi-192 kbps utshintsho aluthethiweyo kwizinto ezininzi; kwi-96 kbps ungava i-cymbals okanye i-sibilants ecocekileyo. I-MOV isiqwengana asiyi kubangela oku - i-codec kuphela emiselweyo ebalulekileyo.

Ingaba i-AMR ekhutshweyo igcina i-MOV inqanaba lesampuli?

Ngokungagqibekanga ewe — 48 kHz MOV isandi siyi 48 kHz AMR isandi, 44.1 kHz siyi 44.1 kHz. Ukuba ufuna ukunyusa isampuli ukuhambelana (umzekelo. 96 kHz studio masters ukuya 44.1 kHz CD-quality AMR) isampuli-rate dropdown yenza oku ngesampuli ephezulu-yexabiso.

Ndingazikhuphela njani ii-AMR zesandi kwisiqulathi seefayili se-MOV?

Ewe — susa isiqulathi seefayili MOV kwindawo yokulayisha kwaye siqhube ukususwa ngokuthe tye. I-Premium ifumana abasebenzi abathe tye abaninzi; kwi-100-file batch (uluhlu lwemiculo-ividiyo) le yi-difference phakathi kweemizuzu ezi-90 nemizuzu eli-8.

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

I-audio demux + transcode iqhuba ngokukhawuleza kunevidiyo yokubuyisela kwikhowudi - ihlala i-5-15% yobude bomthombo. Iyure ye-1 MOV -> AMR igqiba kwimizuzu ye-3-9 kwindlela eqhelekileyo yokuhambisa. Ukuba i-AMR codec ifana ne-source codec sele kwi-MOV (eqhelekileyo kwi-AAC ngaphakathi MKV / MP4), yi-remux ecocekileyo kwaye iqhuba kwimizuzu.

Ingaba ifayili AMR izakuthwala isihloko / umculi / i-tag ye-albham?

Ukuba i-MOV ifayili igcina i-metadata yokuhamba (umculi, isihloko, i-albham), sikopa ezi ndawo kwi AMR isiqulathi seefayili apho ifomati ixhasa ii-tags. ID3v2 (MP3), i-Vorbis iphawula (OGG, FLAC), i-MP4 i-atoms (AAC / M4A), RIFF INFO (WAV) zonke zibhalwe. I-Untagged MOV ivelisa i-untagged AMR — sebenzisa i- Mp3tag okanye i-Picard emva-korhwebo ngaphandle ukunika amandla.

Ingaba i MOV yam ifihlakeleyo xa ndisusa umsindo?

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngalinye. Umsuka MOV nemveliso AMR ziqhubekekiswa kubasebenzi abakhuselekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise imixholo. Bona /privacy/.

MOV

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

AMR

I-AMR (I-Adaptive Multi-Rate) yifomathi yocinezelo lwe-audio elungiselelwe ikhowudi yentetho. Iqhele ukusetyenziswa kwiifowuni eziphathwayo ukwenzela ukurekhoda kwelizwi kunye nokudlala kwakhona.
