Indlela yokuguqula MOV ukuba AMR

Inyathelo 1: Layisha eyakho MOV iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

Inyathelo lesi-3: Khuphela i-converted yakho AMR iifayile

MOV ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani i-audio kwifayili MOV njenge AMR?

Layisha phezulu ifayili ye MOV kwaye siyi-demux i-audio track, emva koko siyi-transcode kwi AMR. Akukho kungena kwevidiyo kwaye akukho kufumana umgangatho ngaphandle kwento ekhoyo kwi-AMR codec; isixhobo /extract-audio/ siqhuba i-pipeline efanayo.

I-AMR ifayili isebenzisa i-bitrate yesandi enjani?

I-AMR emiselweyo ye-bitrate yi-192 kbps (ibonisa ngaphaya kwengoma). Nciphisa ukuya kwi-320 kbps (i-audiophile), 128 kbps (i-podcast eqhelekileyo), okanye i-96 kbps (ilizwi/ifayili encinci). Ukhetho lutshintshiselana ngobungakanani befayili ngokuchasene nobuxoki obunokulungiswa kwaye lubonakaliswa kwiinketho eziphambili phambi kokuguqula.

Ingaba ndiya kulahlekelwa umgangatho wesandi xa ndisuka kwi-MOV ukuya kwi-AMR?

Ukuba AMR ayilahleki (WAV, FLAC), yonke isampuli yombhalo ovela kumbhalo wesandi igcinwa ngokuchanekileyo. Ukuba AMR ilahlekile (MP3, AAC, OGG, Opus), i-AMR codec iphinda icinezele — kwi-192 kbps emiselweyo le nto icacile kuzo zonke izinto ezivela kumbhalo.

Ingaba i-AMR ekhutshweyo igcina i-sample rate yangaphambili?

Ngokungagqibekanga ewe — i-48 kHz yothotho lwesandi ngaphakathi kwe MOV ivela kwi-48 kHz ngaphakathi kwe AMR. Ukuba ufuna i-44.1 kHz (uthelekiso lwe-CD-quality) i-sample-rate ephambili ehla-phantsi iphatha i-resample ngecebo lokucoca ulwelo eliphezulu le-quality (akukho zinto ezibonakalayo ezibizwa ngokuba zi-alias).

Ndingayikhupha i-audio kwiifayili ezininzi MOV kwi AMR kwiqela elinye?

Ewe — susa isiqulathi seefayili MOV ngaphakathi kwaye sikhuphe isandi ngokuthe tye. Abasebenzisi abaphezulu bafumana abasebenzi abathe tye abaninzi kwaye akukho bungakanani befayili nganye obuphezulu; kwifayili ye-50-iqela lento le yinto eyahlukileyo phakathi kweemizuzu ezili-90 nemizuzu eli-8.

Ingaba ifayili AMR iya kuphawulwa ngesihloko / umculi / i-albham?

Ukuba i-MOV ifayile inesihloko okanye i-metadata yokuhamba (eqhelekileyo kwi-DVD rips, iipodcasts, iividiyo zengoma), sikopa umculi / isihloko / imihlaba ye-albham kwi AMR isiqulathi seefayili. Amacebo angaphawulwanga MOV avelisa AMR angaphawulwanga — sebenzisa umhleli we-tag (Mp3tag, Picard, MusicBrainz) emva koko ukuba ii-tags ezininzi zibalulekile.

Ithatha ixesha elingakanani ukushenxisa i-AMR kwifayili ye-MOV?

Ukutsala isandi kukhawulezayo kakhulu kunokuphinda kubhalwe ikhowudi ividiyo - ngokuqhelekileyo 5-15% yobude bomthombo. Iyure ye-1 MOV → AMR igqiba kwimizuzu ye-3-9 kwinkqubo eqhelekileyo; ividiyo yemizuzu emi-5 igqiba ngaphantsi kwemizuzu.

Ndingayikhupha icala le-MOV yesandi njenge-AMR?

Akukho kulo mhlathi - khupha isandi esipheleleyo njenge AMR kuqala, emva koko sebenzisa /audio-trim/ ukucima icandelo. Umendo wenyathelo elinye ukhawulezayo kunenkqubo edityanisiweyo kwaye ukuvumela ukuba ujonge kuqala isandi esikhutshiweyo phambi kokucima.

Ingaba ifayili yam MOV ifihlakeleyo xa ndikhupha isandi?

Ewe — imodeli yobumfihlo efanayo neyokuguqulwa ngalinye kwiwebhusayithi: abasebenzi abakhuselekileyo, ukucinywa okuzenzekelayo kwimizuzu, akukho hlaziyo lomsebenzisi lweaudiyo okanye imixholo yevidiyo. Bona /privacy/.

Kutheni ifayili yam AMR isebenzisa izithuba ezingasebenziyo?

Iindawo ezizitshixo zihlala zithetha ukuba ifayili MOV inenkqubo yesandi eninzi-ye-track (igqalelo, ulwimi olutshintshiweyo, iziqhagamshelanisi ezijikelezayo) kwaye sikhethe umsinga ongafanelekanga. Sebenzisa ukhetho oluphambili "umsinga wesandi" ukukhetha ngokucacileyo umsinga 0, 1, njl.njl., okanye uphinde uhlanganise zonke iziqhagamshelanisi kwi-multi-track AMR isiqwenga ukuba AMR ixhasa oko.

Ingaba ukususwa kwe AMR ku stereo, mono, okanye 5.1?

Ubeko lwesiqhagamshelanisi lugcinwa ukusuka kwi MOV ngokumiselweyo — i-5.1 MOV ivelisa i-5.1 AMR apho i-codec ixhasa khona (AAC, FLAC, OGG, Opus). Iforce stereo okanye mono nge-channel-downmix option; isetyenziswa kwi-podcast workflows okanye ukudlala nge-bandwidth ephantsi.

Ingaba i-AMR ekhutshiweyo iyadlala kwi-iPhone, Android, okanye kwi-stereo yemoto?

I-MP3 idlala jikelele. I-AAC / M4A idlala kwi-Apple neyo yonke i-Android. I-OGG / Opus ifuna umdlali okutsha kwi-iOS kodwa idlala kakuhle kwi-Chrome / Firefox / VLC. Isixhobo esiphambili esimiselweyo sikhetha i-AMR codec enokuthi idlala kwinkqubo yakho emiselweyo.

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.
