MPG kuya WMV Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Uma ama-MPG ne-WMV amabhokisi angaba nesixhumi esifanayo (H.264, H.265, VP9, AV1), umguquli ubuyela emuva ku-remux: ama-streams aphansi akopiwe ngo-byte-by-byte ku-WMV ibhokisi futhi ushintsho lwe-wrapper kuphela. I-remux ye-1 GB MPG ku-WMV ivame ukuqedwa ngamasekondi angama-5-15 ngaphandle kokulahlekelwa umgangatho. Okuqukethwe yi-MPEG-1 noma i-MPEG-2 video ne-MP2 umsindo; ukuxhuma kanye nesakhiwo se-GOP kufana nehele le-.mpeg. WMV ithatha Microsoft VC-1 noma WMV3 video nge WMA audio - codecs cishe akukho ngaphandle Windows decodes natively.

I MPG yami inezinhlamvu zomsindo eziningi — zingaba zonke zihlala ngaphakathi kwe WMV?

Akunakuthembeka. MPG igcina imisindo eminingi njengezingoma zohlobo lokuqala, kodwa WMV uxhaso lokudlala ngaphezu kwengoma yokuqala akulingani, ngakho abadlali abaningi bazoveza kuphela eyodwa. Khetha ingoma oyifunayo ngaphambi kokuguqula; abanye bakhishwa kahle kumafayela abo ngaphezu kokushiya emgodini ofihlayo. MPG yisibonisi sesoftware ye-DVD, ama-camcorders adala kanye nezixhobo zokusakaza ziyazi, ngakho ihlala isetshenziswa ezipayipini. WMV ngokuphumelelayo iphele efile: macOS, iOS, Android kanye nesipiliyoni ngasinye idinga isithathu-party decoders, futhi ezinye WMV amafayela zithwala DRM ukuthi akufanele kushintshwe ngaso sonke isikhathi.

Ingabe i-WMV izodlala ngokulula ku-smartphone noma ku-TV?

Kungenzeka ukuthi ayisebenzi. MPG i-decoded yi-silicon ekhethekile kumafoni, ama-tablets nama-TV, ngakho-ke idlala ngaphandle kokucindezela ibhethri. WMV ngokuvamile ibuyela emuva ku-software decoding ku-hardware efanayo - u-CPU ophezulu, isisetshenziswa esipholile, namafreyimu akhuphuka ku-4K material. Uhlelo oluzosetshenziswa, MPG luyi-container ephephile yokuhlala kuyo.

Ingabe kukhona okushintshayo phakathi kwefomethi ezimbili ezidalayo njenge MPG ne WMV?

Uma nje ingxenye ekhethekile yemishini idinga isiphetho. Ifomethi zombili zivela kusikhathi esifanayo se-H.264, ngakho noma yikuphi ukushintshana kuthengiswa ukusebenza kahle, ukhwalithi noma ubufakazi bokuphila - kuthengiswa ukuhambisana nedivayisi eyodwa ekhethekile. Uma inhloso ukugcina isithombe esisetshenziswayo isikhathi eside, ukuguqula kwibhokisi elikhona endaweni ye-sideways. MPG ithola wonke ama MPEG-2 amaphutha - i-bitrate enzima, ukuxhuma, akukho ngezansi okuthambile - kanye nokungqubuzana kwezinhlamvu ezimbili ezibanzi zefomethi eyodwa.

Ingabe umsindo ogcwele uzoqhubeka nokuguqulwa MPG kuya ku WMV?

Yebo — wonke umculo ohambayo ku MPG (umbono womqondisi, izilimi ezihlukile, umculo ochazayo) ugcinwa ku WMV 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. WMV Windows Media Video, Microsoft ASF-based format kusuka Windows XP isikhathi.

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

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

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

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

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

Yini i-codec esetshenziswa yi-WMV ngokuzenzakalela?

I-codec ejwayelekile ikhethiwe ukufana ne WMV 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. WMV icindezela kahle ngenxa yobudala bayo futhi ihlala ifomu PowerPoint, Windows edlule screen recorders kanye corporate media libraries ulindele.

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

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

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

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

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

MPG

I-MPG iyisandiso sefayela samafayela evidiyo e-MPEG-1 noma e-MPEG-2. Ngokuvamile isetshenziselwa ukudlalwa kwevidiyo nokusabalalisa.

WMV

I-WMV (I-Windows Media Video) ifomethi yokucindezela ividiyo eyakhiwe yi-Microsoft. Ivame ukusetshenziselwa ukusakaza kanye nezinsizakalo zevidiyo eziku-inthanethi.
