MKV kuya MPG Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Uma ama-MKV ne-MPG amabhokisi angaba nesixhumi esifanayo (H.264, H.265, VP9, AV1), umguquli ubuyela emuva ku-remux: ama-streams aphansi akopiwe ngo-byte-by-byte ku-MPG ibhokisi futhi ushintsho lwe-wrapper kuphela. I-remux ye-1 GB MKV ku-MPG 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. Okuqukethwe yi-MPEG-1 noma i-MPEG-2 video ne-MP2 umsindo; ukuxhuma kanye nesakhiwo se-GOP kufana nehele le-.mpeg.

Yini ezoba nezinhlamvu zesihloko esingezansi kuhele lwami MKV?

Ngakhoni ukuhlala bekhethwa, ngoba MPG ayikho i-soft-subtitle stream egcina isihloko. Kunezindlela ezimbili zokuzikhipha: ukufaka kuvidiyo ngesikhathi sokuguqulwa, okuzozenza zihlala zihlala futhi zingashintshwa, noma ukuthumela ngaphandle njenge.srt ehlukile ecaleni le MPG ukuze umdlali alayishe. Umguquli utshela ukuthi yini eyayenza ngaphandle kokushiya isihloko ngokucophelela. MPG ithola wonke ama MPEG-2 amaphutha - i-bitrate enzima, ukuxhuma, akukho ngezansi okuthambile - kanye nokungqubuzana kwezinhlamvu ezimbili ezibanzi zefomethi eyodwa.

Kungani ngiguqula i-MKV ibe yifomethi edala njenge-MPG?

Ngenxa yokuthi iningi lezinto ezibonakalayo alikwazi ukufundela noma yini entsha futhi alizokwazi. Ama-DVD adlalayo, amayunithi emoto, ama-camcorder adlalayo, ama-displays emboni kanye nemikhiqizo eminingi yokusabalalisa i-ingest i accept MPG futhi akukho okuningi. Ukuguquka kuyindlela efanele yokuncipha ekusebenzani, ethengiswe ukushintshana kokusebenza kwidivayisi engakho enye indlela. MPG yisibonisi sesoftware ye-DVD, ama-camcorders adala kanye nezixhobo zokusakaza ziyazi, ngakho ihlala isetshenziswa ezipayipini.

Ingabe umsindo ogcwele uzoqhubeka nokuguqulwa MKV kuya ku MPG?

Yebo — wonke umculo ohambayo ku MKV (umbono womqondisi, izilimi ezihlukile, umculo ochazayo) ugcinwa ku MPG 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. MPG iyi-MPEG i-program stream efanayo ne-.mpeg — isibonisi sokubhala esithathu siyi-DOS-era truncation, hhayi i-format ehlukile.

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

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

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

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

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

I-codec ejwayelekile ikhethiwe ukufana ne MPG 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.

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

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

Ingabe i MKV kuya ku MPG 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 MPG 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 MPG ngezinhloso ezinomthelela.

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

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