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.

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?

Ingoma enye, ekhethiweyo ngokuzenzekelayo: ngokuqhelekileyo enye enkulu, ingoma eneendawo ezininzi. Eli phepha alinakucwangciswa ukukhetha ingoma eyahlukileyo kwaye alidwelisi iingoma kwifayili. Ukuba ufuna ugqaliso okanye udub endaweni yoko, yenza i-remux ye-MOV ngengoma yokuqala (i-VLC okanye i-ffmpeg ingakwenza oku) kwaye uyiguqule kwakhona.

I-AMR ifayili isebenzisa i-bitrate enjani?

I-lossy AMR ikhowudiwe kwi-192 kbps ngokumiselweyo. Isicwangciso Somgangatho Wesandi sinika 320 kbps kumgangatho olungileyo kunye ne-128 kbps kwifayili encinci. I-lossless AMR (WAV, FLAC) i ignores the bitrate and keeps every sample.

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?

Iifayile ezininzi kumsebenzi omnye zifuna inkqubo ehlawulweyo. Ukusetyenziswa okukhululekileyo yifayile enye ngoguqulelo, uguqulelo olunye ngeyure. Kwinkqubo ehlawulweyo ungadibanisa iifayile ezininzi kumsebenzi omnye, emva koko ulayishe impumelelo nganye kwiyo okanye zonke kwi ZIP enye.

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

Oku kuxhomekeke kubungakanani nobude befayile. Amaxwebhu amancinci kunye nemifanekiso ihlala ilungile ngokukhawuleza. Iividiyo ezide zithatha ixesha elide, kuba iinguqulelo ezininzi zevidiyo ziphinde zikhowudi iframe nganye.

Ingaba i MOV yam ifihlakeleyo xa ndisusa umsindo?

Ewe. Iifayile ezilayishwe phezulu ze MOV ziqhubekekiswa kwiseva yethu yokuguqula, akukho mntu ujonge phezulu, kwaye azisasazwanga. Ukukhuphela kunye nokuguqulwa kwe AMR kususwa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa, oshiya ixesha lokulayisha ezantsi iziphumo. Bona /privacy/ kwinkqubo epheleleyo.

Kutheni i AMR yam isebenzisa izithuba ezizinyamalalayo okanye isebenzisa isandi esingalunganga?

I MOV ihlala ithatha ngaphezulu kwendlela enye yesandi kwaye enye eyaguqulwa ihlala ikhululekile okanye isibini. Umguquli ukhetha indlela enye yesandi ngokuzenzekelayo, ihlala iphambili, kwaye eli phepha alinakho ukumisela ukukhetha indlela eyahlukileyo. Ukuba enye engalunganga iphuma, yenza i MOV iphinde iguqulwe ngendlela oyifunayo kuqala (i-VLC okanye i-ffmpeg ingakwenza oku) kwaye uyiguqule kwakhona.

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.
