AV1 kuya MKV Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Uma ama-AV1 ne-MKV amabhokisi angaba nesixhumi esifanayo (H.264, H.265, VP9, AV1), umguquli ubuyela emuva ku-remux: ama-streams aphansi akopiwe ngo-byte-by-byte ku-MKV ibhokisi futhi ushintsho lwe-wrapper kuphela. I-remux ye-1 GB AV1 ku-MKV 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. MKV i codec-agnostic: H.264, HEVC, VP9 kanye AV1 ividiyo uhlala ejabulisayo eduze AAC, FLAC, Opus, DTS noma Dolby umsindo kwifayela efanayo.

Ingabe ngingakwazi ukuxhuma ihele kwikhasi le-web ngemuva kokushintsha AV1 kuya ku MKV?

Akunakuqondile. AV1 idlala ngaphakathi kwelayini ngayinye yesiphequluli; MKV 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-MKV njenge-archive noma uhlela ikhophi. MKV ayikho ngaphezu kwe-hardware yendawo yosizo — amafoni, iziphequluli ne TVs ngokuvamile udinga VLC noma remux ngaphambi kokuba badlala.

Ingabe MKV 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 MKV?

Yebo — wonke umculo ohambayo ku AV1 (umbono womqondisi, izilimi ezihlukile, umculo ochazayo) ugcinwa ku MKV 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. I-MKV yi-Matroska, ibhokisi elivulekile elihlolwe ngo-2002 ngaphandle kokwenqaba kwelayisense futhi akukho phezulu okwazi ukuwugcina.

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

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

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

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

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-MKV ushiya lezi zifomethi lapho i-MKV 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-MKV ngokuzenzakalela?

I-codec ejwayelekile ikhethiwe ukufana ne MKV 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. I-MKV iyindawo yokugcina ekhethiwe ngoba igcina imisindo engaphelelanga, izihloko ezilula, izihloko eziphawulekayo kanye nezithombe zobuso kwifayela elilodwa.

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

I-HDR metadata ehlala njalo (i-HDR10 mastering display values, max content light level) ihamba phambili ku-MKV 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-MKV isihlungi esingathwala i-DV layer ihamba phambili ku-HDR10.

Ingabe i AV1 kuya ku MKV 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 MKV 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 MKV ngezinhloso ezinomthelela.

Kungani ihele lami MKV 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 MKV (ukufaka iwebhu) kuyisizathu esivame kakhulu sokulahlekelwa okuningi.

Ingabe i-AV1 kuya ku-MKV 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-MKV iphele ngokudluliswa kwediski I/O, hhayi i-CPU — i-30 GB AV1 ivame ukudluliswa ku-MKV 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.
