M4V kuya MOV Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-M4V ibe yi-MOV ngaphandle kokubuyisela umbhalo ongezansi wevidiyo?

Uma ama-M4V ne-MOV amabhokisi angaba nesixhumi esifanayo (H.264, H.265, VP9, AV1), umguquli ubuyela emuva ku-remux: ama-streams aphansi akopiwe ngo-byte-by-byte ku-MOV ibhokisi futhi ushintsho lwe-wrapper kuphela. I-remux ye-1 GB M4V ku-MOV ivame ukuqedwa ngamasekondi angama-5-15 ngaphandle kokulahlekelwa umgangatho. Ukuthuthukiswa M4V MP4 - H.264 noma HEVC nge AAC - nge optional Apple FairPlay DRM ne iTunes isiqephu metadata. I-MOV ivame ukuthwala i-H.264 noma i-HEVC yokudlulisa, noma i-ProRes uma iyi-editor master, kanye ne-AAC noma umsindo we-PCM ongacindezelwa.

Ingabe M4V ingaguqulwa ibe MOV ngaphandle kokuphinde ubhale kabusha ividiyo?

Yebo, futhi yindlela esheshayo. M4V ne MOV zihlanganisa isakhiwo sebhokisi esifanayo esingaphansi, ngakho ividiyo nesandi sokushayela zikopiwe nge-byte-by-byte futhi isiqoqi sokushayela kuphela sibhale kabusha. Akukho okuqokwa futhi akukho okucindezelwa, ngakho ihele lezici ezide liqedwa ngaphansi kwemizuzu endaweni yehora elilodwa, nekhwalithi yesabelo esifanayo nesomthombo. M4V Apple's uhlobo MP4, esetshenziswa iTunes kanye Apple TV app for movies kanye TV iziqephu. MOV Apple's QuickTime isitsha, ethunyelwe ngo-1991 futhi akazange ashintshe ifomu iPhone, iPad noma Final Cut Pro timeline ubhala ngokuzenzakalela.

Kungani ihele lami M4V lingakwazi ukushintsha ku MOV?

Kuyinto evamile kakhulu i-DRM. Ezinye M4V izithombe zibhalwe ngokufihlakele ku-bitstream level yisitolo noma isofthiwe eyenza, futhi isithombe esibhalwe ngokufihlakele asikwazi ukucinywa yithu noma yinoma yini ngaphandle kwesitshixo selayisense. Izithombe ongazirekhodile, ozenzayo noma ozibhumele ngaphandle azikhuselwanga ziguqulwa ngokuvamile; ukuthenga okusemthethweni akuzokwenza, futhi akukho oguqulelayo angaba nesiqiniseko sokuthi kungashintshwa. DRM-ikhuselwe M4V ukuthenga ngeke kushintshwe yinoma yini; kuphela M4V izithombe ezingakhuselwanga ziguqulwe, futhi abadlali Apple-ayikho njalo kufanele ubanzi kuthiwa.

Ingabe umsindo ogcwele uzoqhubeka nokuguqulwa M4V kuya ku MOV?

Yebo — wonke umculo ohambayo ku M4V (umbono womqondisi, izilimi ezihlukile, umculo ochazayo) ugcinwa ku MOV lapho isiqoqi esizosiza umsindo ohambayo oningi. MKV ne MOV ziphatha umculo ohambayo ongenasiphelo; MP4 isekela abaningi kodwa abanye abadlali behardware babona umculo 1 kuphela; WebM iphele ku-Opus / Vorbis umculo owodwa.

Ingabe amabhayisikobho esihloko esingezansi agcinwa uma kuguqulwa M4V kuya ku MOV?

Izihloko ezincane ezilula (izihloko ezikhethiwe) zihlala lapho MOV zingazithwala: MKV igcina i-SRT, ASS, SSA, PGS, VobSub ngokusemthethweni; MP4 igcina kuphela i-mov_text (ifomethi ephukile). Ukushintsha MKV nge-ASS styled subs ku-MP4 kuzozikhuphula zibe yi-mov_text noma zizicwebezele. Izihloko ezinzima (zicwebezelelwe kwividiyo) zithwale ngaphandle kokungabaza.

Ingabe M4V kuya ku MOV igcina iziphawuli zesiga-nyezi / ukuzula kwe-DVD-style?

Isigaba se-metadata sidlulisa phakathi kuka M4V no MOV lapho izihlungi zombili zixhasa isiqephu se-atomi (MKV, MP4, MOV). I-WebM igcina iziqephu kwi-Matroska-compatible block, ngakho-ke i-MKV <-> isigaba se-WebM sihamba ngokuhlanzekile. I-AVI ayinasiqephu esicacisiwe, ngakho-ke ukushintsha i-AVI ibe yi-MOV kwenza ifayela elingahlukanisiwe ngaphandle kokuthi uhlanganise iziphawuli ngesandla.

Yini mayelana nezifakiwe ze-MKV (izifomethi, isigqoko somsebenzi) uma usuka ku M4V usuka ku MOV?

MKV yindawo yokugcina eyinhloko kuphela egcina amafayela axhunywe ngokuzenzakalela (izifomethi ze-TTF ze-ASS subs, isithombe sokuzivikela se-JPG, izingeniso ze-PDF eziguqulwe nge-fan). Ukusuka ku-M4V kuya ku-MOV ushiya lezi zifomethi lapho i-MOV ingakho MKV — ama-streams aphansi aguqulwa, kodwa umthwalo oxhunywe uhlala emsuka. Gcina i-M4V njenge-backup uma uhlala ubheke izifomethi ezixhunywe.

Yini i-codec esetshenziswa yi-MOV ngokuzenzakalela?

I-codec ejwayelekile ikhethiwe ukufana ne MOV isitoreji ngokuzithandela: MKV ikhetha i-H.265 (HEVC) ukucindezela okuhle; MP4 ikhetha i-H.264 ukuxhasa isisetshenziswa esibanzi; WebM ikhetha i-VP9; AVI isebenzisa i-MPEG-4 ASP (DivX/Xvid lineage). Nciphisa nge-codec ethuthukisiwe engezansi — AV1 itholakala ku-MKV / WebM lapho ufuna khona ukucindezela okuphezulu futhi ungalindela ukucindezela. MOV yifomethi abashicileli abaqeqeshiwe bacela, ngoba ihlala iphinda i-round-trips nge Final Cut Pro, Premiere ne DaVinci Resolve ngaphandle kokulahlekelwa kohlobo. Amafayela MOV akhulu, futhi ngaphandle kwe-Apple ecosystem ukusakazwa kosizo kuncane kuna-MP4 - ama-Android adala futhi amanye ama-Smart TVs azowayeka.

Ingabe i-HDR (HDR10, Dolby Vision) ihlala isikhathi eside M4V kuya ku-MOV?

I-HDR metadata ehlala njalo (i-HDR10 mastering display values, max content light level) ihamba phambili ku-MOV uma izihlungi zombili ne-codec ekhethiwe ziyixhasa (HEVC, AV1 ku-MKV / MP4). I-Dolby Vision inamandla kakhulu — i-DV profile 5 / 7 / 8.1 ku-M4V ihlala kuphela ku-MKV nge-HEVC; ukushintsha ku-MOV isihlungi esingathwala i-DV layer ihamba phambili ku-HDR10.

Ingabe i M4V kuya ku MOV igcina ifreyimu eshintshayo (VFR)?

MKV ne WebM zirekhoda ama-timestamps we-frame ngayinye futhi ziphatha i-VFR ngokusemthethweni, ngakho-ke i-M4V VFR ihlala i MOV yalezi fomu ngaphandle kokuphindeka kokuhlolwa. I-MP4 igcina ama-timestamps futhi kodwa abanye abadlali bakholelwa ukuthi i-CFR; umguquli ubonisa "u forza CFR" ukushintsha okuphinda ukuhlolwa kwe-VFR M4V kuya ku-24 / 30 / 60 fps MOV ngezinhloso ezinomthelela.

Kungani ihele lami MOV lincane / likhulu kuna M4V ngemuva kokuguqulwa?

I-remux ye-codec efanayo ikhiqiza ubukhulu obufana kakhulu (i-container overhead ihluka ngo-0.1-2%). Ushintsho lwe-codec lungashintsha ubukhulu ngo-50% noma ngaphezulu: H.264 kuya ku-H.265 ngokuvamile kushiya ihele ngaphesheya ngekhwalithi efanayo yokubuka; H.264 kuya ku-AV1 kushiya ihele ngaphesheya futhi ngesinqumo esihamba kancane. Ukusuka ku-high-bitrate M4V (Blu-ray rip) kuya ku-low-bitrate MOV (ukufaka iwebhu) kuyisizathu esivame kakhulu sokulahlekelwa okuningi.

Ingabe i-M4V kuya ku-MOV iphatha okuqukethwe kwe-4K / 8K / 60fps?

Yebo kuze kube yi-8K (7680x4320) ku-Premium. Izinga elimahhala liphatha i-4K (3840x2160) kuze kube yi-1 GB yehele. I-pure remuxes (i-codec efanayo edlula) ye M4V enkulu iye ku-MOV iphele ngokudluliswa kwediski I/O, hhayi i-CPU — i-30 GB M4V ivame ukudluliswa ku-MOV ngaphansi kwemizuzu ngaphandle kokuqhathaniswa nesinqumo. Iphinde ikhode isilinganiso ngenani le-pixel.
