AV1 kuya MOV Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-AV1 ibe yi-MOV ngaphandle kokubuyisela umbhalo ongezansi wevidiyo?

Uma ama-AV1 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 AV1 ku-MOV ivame ukuqedwa ngamasekondi angama-5-15 ngaphandle kokulahlekelwa umgangatho. AV1 yi-codec, hhayi isiqoqi — i-bitstream ihamba ngaphakathi MP4 noma WebM, ixhunywe ne-Opus noma i-AAC umsindo. 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 ngingakwazi ukuxhuma ihele kwikhasi le-web ngemuva kokushintsha AV1 kuya ku MOV?

Akunakuqondile. AV1 idlala ngaphakathi kwelayini ngayinye yesiphequluli; MOV ayisebenzi, ngakho ikhasi elifakazelayo libuyela emuva ku-download link noma ku-player frame engenanto. Uma ihele lizosetshenziswa kwi-website, gcina i-AV1 kwi-web futhi uthathe i-MOV njenge-archive noma uhlela ikhophi. Amafayela MOV akhulu, futhi ngaphandle kwe-Apple ecosystem ukusakazwa kosizo kuncane kuna-MP4 - ama-Android adala futhi amanye ama-Smart TVs azowayeka.

Ingabe MOV iyibhokisi noma i-codec, futhi ngabe lokhu kushintsha lokho engikutholayo emuva?

Ishintsha ukuthi yini ongayilindele kuhele lwesingeniso. Ingxenye eyodwa yokuguqulwa ibizwa ngokuthi ukungenisa ngaphandle, hhayi ukupakisha, ngakho lokho okubuyayo ukuthi i-bitstream ngaphakathi kwebhokisi elifanele kakhulu — ngokuvamile MP4 noma MKV. Uhlelo lubonisa ibhokisi; i-codec yilokho okusho ubukhulu befayela futhi lapho izodlala khona.

Ingabe umsindo ogcwele uzoqhubeka nokuguqulwa AV1 kuya ku MOV?

Yebo — wonke umculo ohambayo ku AV1 (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. MOV Apple's QuickTime isitsha, ethunyelwe ngo-1991 futhi akazange ashintshe ifomu iPhone, iPad noma Final Cut Pro timeline ubhala ngokuzenzakalela.

Ingabe amabhayisikobho esihloko esingezansi agcinwa uma kuguqulwa AV1 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 AV1 kuya ku MOV igcina iziphawuli zesiga-nyezi / ukuzula kwe-DVD-style?

Isigaba se-metadata sidlulisa phakathi kuka AV1 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 AV1 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-AV1 kuya ku-MOV ushiya lezi zifomethi lapho i-MOV ingakho MKV — ama-streams aphansi aguqulwa, kodwa umthwalo oxhunywe uhlala emsuka. Gcina i-AV1 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.

Ingabe i-HDR (HDR10, Dolby Vision) ihlala isikhathi eside AV1 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-AV1 ihlala kuphela ku-MKV nge-HEVC; ukushintsha ku-MOV isihlungi esingathwala i-DV layer ihamba phambili ku-HDR10.

Ingabe i AV1 kuya ku MOV igcina ifreyimu eshintshayo (VFR)?

MKV ne WebM zirekhoda ama-timestamps we-frame ngayinye futhi ziphatha i-VFR ngokusemthethweni, ngakho-ke i-AV1 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 AV1 kuya ku-24 / 30 / 60 fps MOV ngezinhloso ezinomthelela.

Kungani ihele lami MOV lincane / likhulu kuna AV1 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 AV1 (Blu-ray rip) kuya ku-low-bitrate MOV (ukufaka iwebhu) kuyisizathu esivame kakhulu sokulahlekelwa okuningi.

Ingabe i-AV1 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 AV1 enkulu iye ku-MOV iphele ngokudluliswa kwediski I/O, hhayi i-CPU — i-30 GB AV1 ivame ukudluliswa ku-MOV ngaphansi kwemizuzu ngaphandle kokuqhathaniswa nesinqumo. Iphinde ikhode isilinganiso ngenani le-pixel.

AV1

I-AV1 iyifomethi yokuminyanisa ividiyo evulekile, engakhokhelwa eyenzelwe ukusakazwa kahle kwevidiyo nge-inthanethi. Inikeza ukusebenza kahle kokucindezela okuphezulu ngaphandle kokuyekethisa ikhwalithi yokubuka.
