M4V ukuba MOV Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-M4V ibe yi-MOV ngaphandle kokubuyisela umbhalo ofihlakeleyo wevidiyo?

Xa i M4V ne MOV iziqulatho zingathatha zombini i-codec efanayo (H.264, H.265, VP9, AV1), umguquli ubuyela umva kwi-remux: imijelo ephambili ikhopiwe i-byte-nge-byte kwi MOV isiqulatho kwaye kutshintsha kuphela umgqomo. I-remux ye-1 GB M4V kwi MOV ihlala igqiba kwimizuzu eyi-5-15 ngaphandle kokufumana inzuzo yomgangatho. Ngokusisiseko i-M4V yi-MP4 — H.264 okanye HEVC nge-AAC — ene-Apple FairPlay DRM ekhethiweyo kunye ne-iTunes isithuba se-metadata. 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.

Ingaba i M4V ingaguqulwa ibe yi MOV ngaphandle kokubuyisela umbhalo ofihlakeleyo wevidiyo?

Ewe, kwaye yindlela ekhawulezayo. M4V ne MOV zisebenzisa ukwakhiwa kwebhokisi ephantsi, ngoko ividiyo kunye nesandi zikhopiwe kwi-byte-kwi-byte kwaye kuphela isiqulathi seefayili sibhalwe kwakhona. Akukho nto ikhowudi kwaye akukho nto iphinde icinezelwe, ngoko ifayile yobude bempawu igqiba ngaphantsi kwemizuzu endaweni yeyure enye, ngemveliso ehambelanayo yobunjani bomthombo. M4V yi-Apple's MP4, esetyenziswa yi-iTunes ne-Apple TV app yefilimu kunye ne-TV. MOV yi Apple QuickTime isiqulathi seefayili, ethunyelwe ngo-1991 kwaye ihlala ifomati iPhone, iPad okanye Final Cut Pro umgca wexesha ubhala ngokumiselweyo.

Ingaba i-audio enezithotho ezininzi izakuhlala iphila ukuguqulwa kwe-M4V ukuya kwi-MOV?

Ewe - yonke i-audio track kwi M4V (umbono womlawuli, iilwimi ezitshintshiweyo, i-audio echazayo) igcinwa kwi MOV xa isiqulathi seefayili esithe nkqo sixhasa i-audio ejikelezayo-eninzi. I-MKV ne-MOV ziphatha ii-audio tracks ezingaqhelekanga; i-MP4 ixhasa ezininzi kodwa abanye abadlali behardware babona kuphela i-track 1; i-WebM icapisiwe kwi-Opus / Vorbis track enye.

Ingaba iingoma zesicatshulwa zigcinwa xa uguqula M4V ukuya ku MOV?

Izihloko eziphantsi ezicocekileyo (iingoma ezikhethiweyo) zihlala zikhona xa MOV zingazithabatha: i-MKV igcina i-SRT, i-ASS, i-SSA, i-PGS, i-VobSub ngokusemthethweni; i-MP4 igcina kuphela i-mov_text (ifomati ethe tyaba). Ukutshintsha i-MKV enezihloko eziphantsi ze-ASS zibe yi-MP4 kuya kuzisa iindidi eziphantsi kwi-mov_text okanye ukutshabalalisa. Iisihloko ezinzima (eziqhutywe kwividiyo) zithatha ngaphezulu nokuba kunjalo.

Ingaba M4V ukuya ku MOV igcina abaphawuli besahluko / ulawulo olufana ne-DVD?

I-metadata yesichazi-magama idlulisa phakathi kwe-M4V ne-MOV xa zombini iziqulatho zixhasa isichazi-magama se-atomic (MKV, MP4, MOV). I-WebM igcina isichazi-magama kwi-Matroska-compatible block, ngoko ke i-MKV <-> i-WebM isichazi-magama sihamba ngokucocekileyo. I-AVI ayinasichazi-magama esichaziweyo, ngoko ke ukuguqula i-AVI ibe yi-MOV yenza ifayili engachazi-magama ngaphandle kokuba udibanisa abaphawuli ngesandla.

Yintoni malunga neziqulathi zeefayili ze-MKV (ifonti, umzobo wesiqulathi seefayili) xa usiya kwi M4V ukuya kwi MOV?

MKV yindawo yokugcina i-mainstream kuphela egcina iifayile ezifakiwe ngokuzithandela (ifonti ze-TTF ze-ASS subs, ubugcisa be-JPG cover, i-fan-translated PDF inserts). Ukusuka kwi M4V ukuya kwi MOV ushiya ezi fayili zifakiwe xa i-MOV ayiyiyo i-MKV — i-elementary streams iguqula, kodwa umthwalo odityanisiweyo uhlala kummthombo. Gcina i-M4V njengengxelo yangaphambili ukuba uxhomekeke kwifonti ezifakelweyo.

Yeyiphi i-codec esetyenziswa yi-MOV kwimveliso ngokumiselweyo?

I-codec emiselweyo ikhethiwe ukuhambelana ne MOV isiqulathi seefayili ngokukhuselekileyo: MKV imiselwe ku-H.265 (HEVC) ukufezekisa ukucinezela okungcono; MP4 imiselwe ku-H.264 ukufezekisa inkxaso yesixhobo esibanzi; WebM imiselwe ku-VP9; AVI isebenzisa i-MPEG-4 ASP (DivX/Xvid lineage). Nciphisa nge-codec ephambili esuka ezantsi — AV1 ifumaneka kwi-MKV / WebM apho ufuna khona ukucinezela okuphezulu kwaye ungalindela ukungenisa ikhowudi. MOV yifomati ababhali abaqeqeshiweyo becela, kuba ihlala iphinda ijikeleze-ihambo nge Final Cut Pro, Premiere ne DaVinci Resolve ngaphandle kokungasebenzi kohlobo. 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.

I-HDR (HDR10, Dolby Vision) ihlala njani M4V ukuya ku MOV?

I-HDR metadata ehlala njalo (i-HDR10 ibonisa amaxabiso aphezulu, umphakamo ophezulu wokukhanya kwezinto eziquletheyo) ihamba phantsi ukuya kwi-MOV xa zombini iziqulatho kunye ne-codec ekhethiweyo ixhasa (HEVC, AV1 kwi-MKV / MP4). I-Dolby Vision inamandla ngakumbi — i-DV profile 5 / 7 / 8.1 kwi-M4V ihlala kuphela kwi-MKV ene-HEVC; ukutshintsha kwi-MOV isiqulatho esingathwali umbala we-DV ihamba phantsi ukuya kwi-HDR10.

Ingaba i-M4V ukuya kwi-MOV igcina i-framerate eguqukayo (VFR)?

MKV ne WebM zirekhoda i-frame nganye yexesha elipheleleyo kunye nokuphatha i-VFR ngokusemthethweni, ngoko ke i-M4V VFR ihlala kwi-MOV yale fomati ngaphandle kokuphindaphinda. I-MP4 igcina i-timestamps ngokusemthethweni kodwa abanye abadlali bakholelwa ukuba i-CFR; umguquli ubonisa "ubunzima be-CFR" ukutshintsha okubuyisela i-VFR M4V ukuya kwi-24 / 30 / 60 fps MOV kwiinjongo ezinomngcipheko.

Kutheni i-MOV ifayili yam incinci / ikhulu kune-M4V emva kokuguqulwa?

I-remux ye-codec efanayo ivelisa ubungakanani obufanayo (i-container overhead ihluka nge-0.1-2%). Utshintsho lwe-codec lunokutshintsha ubungakanani nge-50% okanye ngaphezulu: H.264 ukuya kwi-H.265 ngokuqhelekileyo iqulethe ifayili kwinqanaba elifanayo lomgangatho wokubona; H.264 ukuya kwi-AV1 iqulethe kwakhona kwi-preset ecocekileyo. Ukusuka kwi-bitrate ephezulu M4V (Blu-ray rip) ukuya kwi-bitrate ephantsi MOV (ukukhuphela kwi-web) yisizathu esiqhelekileyo sokuhla okuphezulu.

Ingaba i-M4V ukuya kwi-MOV iguqula i-4K / 8K / 60fps iqulethe?

Ewe ukuya kwi-8K (7680x4320) kwi-Premium. Umphakamo okhululekileyo uphatha i-4K (3840x2160) ukuya kwi-1 GB yefayili. I-pure remuxes (i-codec efanayo edlulayo) ye M4V enkulu kwi-MOV imiselwe yi-disk I/O, hayi i-CPU — i-30 GB M4V iqhelekileyo i-remuxes kwi-MOV ngaphantsi komzuzu ngaphandle kokuxhomekeka kwi-resolution. I-re-encodes i-scale nge-pixel count.

Ingaba i-M4V yam ifayile ifihlakeleyo ngexesha lokuguqulwa kwe-MOV?

Ewe — iifayile ezilayishwe phezulu M4V ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu yokuphela. Asizukuzijonga, sizigcine, sizigcine, okanye sizonwabele iziqulatho. Bona /privacy/ kwifestile yokugcina i-data. Inkqubo yokuguqula iqhuba kwihardware esilawulayo ukusuka ekupheleni ukuya ekupheleni; akukho qela lesithathu le-APIs lifumana ifayili yakho. I-M4V igcina abaphawuli besiqendu, umsebenzi wobugcisa kunye nengoma yesihloko esingaphantsi kwisimo i-Apple TV app ilindeleyo, eyona MP4 iqhelekileyo ihlala ilahlekelwa yiyo.
