WebM kuya MPG Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Uma ama-WebM 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 WebM ku-MPG ivame ukuqedwa ngamasekondi angama-5-15 ngaphandle kokulahlekelwa umgangatho. WebM idinga ukucophelela: VP8 noma VP9 ividiyo (AV1 manje) nge Vorbis noma Opus umsindo, futhi akukho okuthile okuningi. 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 WebM?

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.

Ingabe i-MPG ingagcina ama-tracks omsindo angaphezu kwesinye?

Yebo, futhi kuyithuthukiso eliyiqiniso ku WebM. MPG iphatha wonke umsindo njengohlelo oluhle, ngakho-ke umsindo ovela ku-language, i-dub kanye nombhali we-comment ungahlala kuhele olulodwa nomdlalo oshintsha phakathi kwazo uma kudingeka. MPG yisibonisi sesoftware ye-DVD, ama-camcorders adala kanye nezixhobo zokusakaza ziyazi, ngakho ihlala isetshenziswa ezipayipini.

Ingabe ngingakwazi ukuxhuma ihele kwikhasi le-web ngemuva kokushintsha WebM kuya ku MPG?

Akunakuqondile. WebM idlala ngaphakathi kwelayini ngayinye yesiphequluli; MPG ayisebenzi, ngakho ikhasi elifakazelayo libuyela emuva ku-download link noma ku-player frame engenanto. Uma ihele lizosetshenziswa kwi-website, gcina i-WebM kwi-web futhi uthathe i-MPG njenge-archive noma uhlela ikhophi.

Kungani ngiguqula i-WebM 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.

Ingabe umsindo ogcwele uzoqhubeka nokuguqulwa WebM kuya ku MPG?

Yebo — wonke umculo ohambayo ku WebM (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 WebM 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 WebM kuya ku MPG igcina iziphawuli zesiga-nyezi / ukuzula kwe-DVD-style?

Isigaba se-metadata sidlulisa phakathi kuka WebM 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 WebM 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-WebM kuya ku-MPG ushiya lezi zifomethi lapho i-MPG ingakho MKV — ama-streams aphansi aguqulwa, kodwa umthwalo oxhunywe uhlala emsuka. Gcina i-WebM 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 WebM 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-WebM ihlala kuphela ku-MKV nge-HEVC; ukushintsha ku-MPG isihlungi esingathwala i-DV layer ihamba phambili ku-HDR10.

Ingabe i WebM kuya ku MPG igcina ifreyimu eshintshayo (VFR)?

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