WMV kuya AVI Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Uma ama-WMV ne-AVI amabhokisi angaba nesixhumi esifanayo (H.264, H.265, VP9, AV1), umguquli ubuyela emuva ku-remux: ama-streams aphansi akopiwe ngo-byte-by-byte ku-AVI ibhokisi futhi ushintsho lwe-wrapper kuphela. I-remux ye-1 GB WMV ku-AVI ivame ukuqedwa ngamasekondi angama-5-15 ngaphandle kokulahlekelwa umgangatho.

Ingabe umsindo ogcwele uzoqhubeka nokuguqulwa WMV kuya ku AVI?

Yebo — wonke umculo ohambayo ku WMV (umbono womqondisi, izilimi ezihlukile, umculo ochazayo) ugcinwa ku AVI 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.

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

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

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

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

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

Yini i-codec esetshenziswa yi-AVI ngokuzenzakalela?

I-codec ejwayelekile ikhethiwe ukufana ne AVI 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 WMV kuya ku-AVI?

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

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

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

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

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

Ingabe ihele lami WMV liyimfihlo ngesikhathi sokuguqulwa AVI?

Yebo — amafayela alayishwe phezulu WMV aphathwa ngabasebenzi abahlukanisiwe futhi asuswa emizuzwini edlulele. Sizohlala sibheka, sigcina, sigcina, noma sihlanganisa okuqukethwe. Bona /privacy/ ngefasitela lokugcinwa kwedatha. Ukuguqulwa kwepayipi luyasebenza kumathuluzi esiwalawulayo kusukela ekuqaleni kuya kukuphela; akukho i-API yeqembu lesithathu ethola ifayela lakho.

Ingabe ngizoyicima, ngiyibeke, noma ngiyihlanganise i WMV ihele ngesikhathi sokuguqulwa AVI?

Ayikho kumsebenzi ofanayo - gcina ukuguqulwa kubhekiswe kubhokisi / codec. Sebenzisa /trim/ ukucindezela i WMV kuqala, bese ufaka i- WMV -> AVI isikhashana. Ukuxhuma ama-clip amaningi ku-AVI, i- /merge/ ithuluzi lizihlanganisa nge-codec ngayinye (i-remuxes uma izingeniso zihlanganisa i-codec, ziphinde zixhume ngakunye) futhi likhipha i-AVI ifayela elilodwa ekugcineni.

WMV

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