MOV ukuba M4V Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Xa i MOV ne M4V 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 M4V isiqulatho kwaye kutshintsha kuphela umgqomo. I-remux ye-1 GB MOV kwi M4V ihlala igqiba kwimizuzu eyi-5-15 ngaphandle kokufumana inzuzo yomgangatho. 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. Ngokusisiseko i-M4V yi-MP4 — H.264 okanye HEVC nge-AAC — ene-Apple FairPlay DRM ekhethiweyo kunye ne-iTunes isithuba se-metadata.

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

Ewe, kwaye yindlela ekhawulezayo. MOV ne M4V 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. MOV yi Apple QuickTime isiqulathi seefayili, ethunyelwe ngo-1991 kwaye ihlala ifomati iPhone, iPad okanye Final Cut Pro umgca wexesha ubhala ngokumiselweyo. M4V yi-Apple's MP4, esetyenziswa yi-iTunes ne-Apple TV app yefilimu kunye ne-TV.

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

Ewe - yonke i-audio track kwi MOV (umbono womlawuli, iilwimi ezitshintshiweyo, i-audio echazayo) igcinwa kwi M4V 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 MOV ukuya ku M4V?

Izihloko eziphantsi ezicocekileyo (iingoma ezikhethiweyo) zihlala zikhona xa M4V 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 MOV ukuya ku M4V igcina abaphawuli besahluko / ulawulo olufana ne-DVD?

I-metadata yesichazi-magama idlulisa phakathi kwe-MOV ne-M4V 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-M4V yenza ifayili engachazi-magama ngaphandle kokuba udibanisa abaphawuli ngesandla.

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

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 MOV ukuya kwi M4V ushiya ezi fayili zifakiwe xa i-M4V ayiyiyo i-MKV — i-elementary streams iguqula, kodwa umthwalo odityanisiweyo uhlala kummthombo. Gcina i-MOV njengengxelo yangaphambili ukuba uxhomekeke kwifonti ezifakelweyo.

Yeyiphi i-codec esetyenziswa yi-M4V kwimveliso ngokumiselweyo?

I-codec emiselweyo ikhethiwe ukuhambelana ne M4V 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. I-M4V igcina abaphawuli besiqendu, umsebenzi wobugcisa kunye nengoma yesihloko esingaphantsi kwisimo i-Apple TV app ilindeleyo, eyona MP4 iqhelekileyo ihlala ilahlekelwa yiyo. I-DRM-ikhuselwe i-M4V ithengiso ayikwazi ukutshintshwa yinto; kuphela iifayili ezikhuselweyo ze-M4V ziyatshintshwa, kwaye abadlali abangama-Apple bafuna uluhlu olubizwa kwakhona.

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

I-HDR metadata ehlala njalo (i-HDR10 ibonisa amaxabiso aphezulu, umphakamo ophezulu wokukhanya kwezinto eziquletheyo) ihamba phantsi ukuya kwi-M4V 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-MOV ihlala kuphela kwi-MKV ene-HEVC; ukutshintsha kwi-M4V isiqulatho esingathwali umbala we-DV ihamba phantsi ukuya kwi-HDR10.

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

MKV ne WebM zirekhoda i-frame nganye yexesha elipheleleyo kunye nokuphatha i-VFR ngokusemthethweni, ngoko ke i-MOV VFR ihlala kwi-M4V 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 MOV ukuya kwi-24 / 30 / 60 fps M4V kwiinjongo ezinomngcipheko.

Kutheni i-M4V ifayili yam incinci / ikhulu kune-MOV 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 MOV (Blu-ray rip) ukuya kwi-bitrate ephantsi M4V (ukukhuphela kwi-web) yisizathu esiqhelekileyo sokuhla okuphezulu.

Ingaba i-MOV ukuya kwi-M4V 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 MOV enkulu kwi-M4V imiselwe yi-disk I/O, hayi i-CPU — i-30 GB MOV iqhelekileyo i-remuxes kwi-M4V ngaphantsi komzuzu ngaphandle kokuxhomekeka kwi-resolution. I-re-encodes i-scale nge-pixel count.

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

Ewe — iifayile ezilayishwe phezulu MOV 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. MOV yifomati ababhali abaqeqeshiweyo becela, kuba ihlala iphinda ijikeleze-ihambo nge Final Cut Pro, Premiere ne DaVinci Resolve ngaphandle kokungasebenzi kohlobo.
