MKV kuya AV1 Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Uma ama-MKV ne-AV1 amabhokisi angaba nesixhumi esifanayo (H.264, H.265, VP9, AV1), umguquli ubuyela emuva ku-remux: ama-streams aphansi akopiwe ngo-byte-by-byte ku-AV1 ibhokisi futhi ushintsho lwe-wrapper kuphela. I-remux ye-1 GB MKV ku-AV1 ivame ukuqedwa ngamasekondi angama-5-15 ngaphandle kokulahlekelwa umgangatho. MKV i codec-agnostic: H.264, HEVC, VP9 kanye AV1 ividiyo uhlala ejabulisayo eduze AAC, FLAC, Opus, DTS noma Dolby umsindo kwifayela efanayo. AV1 yi-codec, hhayi isiqoqi — i-bitstream ihamba ngaphakathi MP4 noma WebM, ixhunywe ne-Opus noma i-AAC umsindo.

Ingabe i-AV1 izodlala kwi-browser uma i-MKV ingadlalanga?

Yebo, futhi lokho kuyisizathu esiphelele sokuguqulwa. I MKV efakwe kwikhasi lewebhu ibonisa umdlali okhubazekile noma icindezela ukulayisha, ngoba iziphequluli azikho izikhombisi ezizo. AV1 idlala ngaphakathi ngengxenye yevidiyo ye-HTML5 engavamile ngaphandle kweplugin noma kusetshenziswa okungaphandle. AV1 inikeza cishe 30% engcono ucindezelo kuna H.264 esezingeni elifanayo futhi ithatha akukho izinkokhelo izitifiketi, okuyinto kungani YouTube ne Netflix push it.

Ingabe AV1 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 MKV kuya ku AV1?

Yebo — wonke umculo ohambayo ku MKV (umbono womqondisi, izilimi ezihlukile, umculo ochazayo) ugcinwa ku AV1 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. AV1 yi-video codec engekho emthethweni ye-Alliance for Open Media ekhishwa ngo-2018 njengengxenye yokulandela i-VP9.

Ingabe amabhayisikobho esihloko esingezansi agcinwa uma kuguqulwa MKV kuya ku AV1?

Izihloko ezincane ezilula (izihloko ezikhethiwe) zihlala lapho AV1 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 MKV kuya ku AV1 igcina iziphawuli zesiga-nyezi / ukuzula kwe-DVD-style?

Isigaba se-metadata sidlulisa phakathi kuka MKV no AV1 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-AV1 kwenza ifayela elingahlukanisiwe ngaphandle kokuthi uhlanganise iziphawuli ngesandla.

Yini mayelana nezifakiwe ze-MKV (izifomethi, isigqoko somsebenzi) uma usuka ku MKV usuka ku AV1?

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-MKV kuya ku-AV1 ushiya lezi zifomethi lapho i-AV1 ingakho MKV — ama-streams aphansi aguqulwa, kodwa umthwalo oxhunywe uhlala emsuka. Gcina i-MKV njenge-backup uma uhlala ubheke izifomethi ezixhunywe.

Yini i-codec esetshenziswa yi-AV1 ngokuzenzakalela?

I-codec ejwayelekile ikhethiwe ukufana ne AV1 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. AV1 encoding ihamba kancane, futhi amathuluzi decoders kuphela wavela kumafoni namahlaya kusukela mayelana 2020 kuqala - amadivayisi adala buyela amandla-ukudla isofthiwe decoding.

Ingabe i-HDR (HDR10, Dolby Vision) ihlala isikhathi eside MKV kuya ku-AV1?

I-HDR metadata ehlala njalo (i-HDR10 mastering display values, max content light level) ihamba phambili ku-AV1 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-MKV ihlala kuphela ku-MKV nge-HEVC; ukushintsha ku-AV1 isihlungi esingathwala i-DV layer ihamba phambili ku-HDR10.

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

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

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

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

MKV

I-MKV (Matroska) ingagcina amavidiyo angenamkhawulo, umsindo, kanye namathrekhi angezansi kufayela elilodwa, okulungele ama-movie.

AV1

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