WMV ukuba M4V Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-WMV ibe yi-M4V ngaphandle kokubuyisela umbhalo ofihlakeleyo wevidiyo?

Xa i WMV ne M4V iziqulatho zingathatha zombini i-codec efanayo (H.264, H.265, VP9, AV1), umguquli ubuyela umva kwi-remux: imijelo ephambili ikhopiwe i-byte-nge-byte kwi M4V isiqulatho kwaye kutshintsha kuphela umgqomo. I-remux ye-1 GB WMV kwi M4V ihlala igqiba kwimizuzu eyi-5-15 ngaphandle kokufumana inzuzo yomgangatho. I-WMV ihambisa i-Microsoft VC-1 okanye i-WMV3 yevidiyo ngesandi se-WMA — ii-codecs azikho nto ngaphandle kweWindows ikhupha ikhowudi ngokusemthethweni. Ngokusisiseko i-M4V yi-MP4 — H.264 okanye HEVC nge-AAC — ene-Apple FairPlay DRM ekhethiweyo kunye ne-iTunes isithuba se-metadata.

I-WMV yevidiyo yam ibonisa imigca ye-comb kwi-movement - iya kuthatha into kwi-M4V?

Iya kwenza ukuba awuyi-deinterlace, kwaye WMV imixholo ihlala i-interlaced ngenxa yokuba ifomati ivela kwixesha le-broadcast ne DVD. Iiframes ezi-interlaced zigcina iindawo ezimbini eziphakathi-ubukhulu eziqhotyoshelwe kwishumi elinesihlanu sesibini; kwifowuni eqhubekayo-yokukhangela okanye imboniselo efunda njenge-horizontal combing nantoni na ehambayo. Yenza ukhetho lwe-deinterlace kwaye i-encoder igubungela iindawo kwi-frames ezipheleleyo eziqhubekayo phambi kokubhala i M4V. WMV yiWindows Media Video, iMicrosoft's ASF-based format ukusuka kwixesha leWindows XP.

Ndingazifaka njani izihloko ezingaphantsi ezikhethiweyo xa ifayili ikwi M4V?

Ewe. WMV ayinayo i-soft-subtitle track esetyenziswayo, ngoko ke i-subtitles ye-WMV iqulethe into ekufuneka ikhutshwe kumfanekiso okanye ithunyelwe njengefayili ye-sidecar eyahlukileyo. M4V ithatha i-subtitles njenge-stream yabo ekhethiweyo, ngoko ke emva kokuguqula ungadibanisa i-SRT track imboniso ingatshintshwa, itshintshwe okanye iphinde iguqulwe.

Ingaba i M4V igcina ngaphezulu kwengoma enye yesandi?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe WMV. M4V iphatha yonke imijelo yesandi njengento ephambili, ngoko udidi lwesivakalisi sokuqala, i-dub kunye nomlawuli wengxelo ingaphila kwifayile enye nomdlali otshintshela phakathi kwabo kwisicelo. I-M4V igcina abaphawuli besiqendu, umsebenzi wobugcisa kunye nengoma yesihloko esingaphantsi kwisimo i-Apple TV app ilindeleyo, eyona MP4 iqhelekileyo ihlala ilahlekelwa yiyo.

Ingaba i M4V inkxaso yamachaphaza ophawu anjengoko WMV ayizange ikwenze?

Iyenza. M4V igcina izihloko njenge metadata yesiqulathi seefayili, ngoko ushicilelo olude lunokuqhubela phambili ngecandelo endaweni yokucoca ibar yokuqhubekeka. WMV ayinanto yokubeka loo nkcukacha, ngoko ukuba umthombo uthunyelwe ngoluhlu lwesihloko yayikwifayile ye sidecar - inikezele kuguquleli kwaye ibhalwe kwi M4V.

Ingaba kufanelekile ukutshintsha i WMV yoshicilelo oludala ukuya kwi M4V?

Ukuba ufuna ukugcina into, ewe. WMV ibhekisa kuhlobo oludlulileyo lwezixhobo zevidiyo kwaye isoftware efunda i-video ihlala iphela kwifowuni, iziphene kunye nenkqubo yokusebenza. Ukushenxisa imifanekiso kwi M4V ngoku, ngelixa i-decoder ecocekileyo ikhona, kuhlukile phakathi kovimba onokuthi uvule kwiminyaka elishumi kunye noyena awukwazi. WMV isebenza kakuhle iphele elahlekile: macOS, iOS, Android kunye ne-browser nganye kufuneka i-decoders yeqela lesithathu, kwaye ezinye iifayile ze-WMV zithwala i-DRM engatshintshi nantoni na.

Ingaba i-audio enezithotho ezininzi izakuhlala iphila ukuguqulwa kwe-WMV ukuya kwi-M4V?

Ewe - yonke i-audio track kwi WMV (umbono womlawuli, iilwimi ezitshintshiweyo, i-audio echazayo) igcinwa kwi M4V xa isiqulathi seefayili esithe nkqo sixhasa i-audio ejikelezayo-eninzi. I-MKV ne-MOV ziphatha ii-audio tracks ezingaqhelekanga; i-MP4 ixhasa ezininzi kodwa abanye abadlali behardware babona kuphela i-track 1; i-WebM icapisiwe kwi-Opus / Vorbis track enye. M4V yi-Apple's MP4, esetyenziswa yi-iTunes ne-Apple TV app yefilimu kunye ne-TV.

Ingaba iingoma zesicatshulwa zigcinwa xa uguqula WMV ukuya ku M4V?

Izihloko eziphantsi ezicocekileyo (iingoma ezikhethiweyo) zihlala zikhona xa M4V zingazithabatha: i-MKV igcina i-SRT, i-ASS, i-SSA, i-PGS, i-VobSub ngokusemthethweni; i-MP4 igcina kuphela i-mov_text (ifomati ethe tyaba). Ukutshintsha i-MKV enezihloko eziphantsi ze-ASS zibe yi-MP4 kuya kuzisa iindidi eziphantsi kwi-mov_text okanye ukutshabalalisa. Iisihloko ezinzima (eziqhutywe kwividiyo) zithatha ngaphezulu nokuba kunjalo.

Ingaba WMV ukuya ku M4V igcina abaphawuli besahluko / ulawulo olufana ne-DVD?

I-metadata yesichazi-magama idlulisa phakathi kwe-WMV ne-M4V xa zombini iziqulatho zixhasa isichazi-magama se-atomic (MKV, MP4, MOV). I-WebM igcina isichazi-magama kwi-Matroska-compatible block, ngoko ke i-MKV <-> i-WebM isichazi-magama sihamba ngokucocekileyo. I-AVI ayinasichazi-magama esichaziweyo, ngoko ke ukuguqula i-AVI ibe yi-M4V yenza ifayili engachazi-magama ngaphandle kokuba udibanisa abaphawuli ngesandla.

Yintoni malunga neziqulathi zeefayili ze-MKV (ifonti, umzobo wesiqulathi seefayili) xa usiya kwi WMV ukuya kwi M4V?

MKV yindawo yokugcina i-mainstream kuphela egcina iifayile ezifakiwe ngokuzithandela (ifonti ze-TTF ze-ASS subs, ubugcisa be-JPG cover, i-fan-translated PDF inserts). Ukusuka kwi WMV ukuya kwi M4V ushiya ezi fayili zifakiwe xa i-M4V ayiyiyo i-MKV — i-elementary streams iguqula, kodwa umthwalo odityanisiweyo uhlala kummthombo. Gcina i-WMV njengengxelo yangaphambili ukuba uxhomekeke kwifonti ezifakelweyo.

Yeyiphi i-codec esetyenziswa yi-M4V kwimveliso ngokumiselweyo?

I-codec emiselweyo ikhethiwe ukuhambelana ne M4V isiqulathi seefayili ngokukhuselekileyo: MKV imiselwe ku-H.265 (HEVC) ukufezekisa ukucinezela okungcono; MP4 imiselwe ku-H.264 ukufezekisa inkxaso yesixhobo esibanzi; WebM imiselwe ku-VP9; AVI isebenzisa i-MPEG-4 ASP (DivX/Xvid lineage). Nciphisa nge-codec ephambili esuka ezantsi — AV1 ifumaneka kwi-MKV / WebM apho ufuna khona ukucinezela okuphezulu kwaye ungalindela ukungenisa ikhowudi. I-DRM-ikhuselwe i-M4V ithengiso ayikwazi ukutshintshwa yinto; kuphela iifayili ezikhuselweyo ze-M4V ziyatshintshwa, kwaye abadlali abangama-Apple bafuna uluhlu olubizwa kwakhona.

I-HDR (HDR10, Dolby Vision) ihlala njani WMV ukuya ku M4V?

I-HDR metadata ehlala njalo (i-HDR10 ibonisa amaxabiso aphezulu, umphakamo ophezulu wokukhanya kwezinto eziquletheyo) ihamba phantsi ukuya kwi-M4V xa zombini iziqulatho kunye ne-codec ekhethiweyo ixhasa (HEVC, AV1 kwi-MKV / MP4). I-Dolby Vision inamandla ngakumbi — i-DV profile 5 / 7 / 8.1 kwi-WMV ihlala kuphela kwi-MKV ene-HEVC; ukutshintsha kwi-M4V isiqulatho esingathwali umbala we-DV ihamba phantsi ukuya kwi-HDR10.

WMV

I-WMV (iVidiyo yeWindows Media) yifomati yocinezelo yevidiyo ephuhliswe nguMicrosoft. Ngokuqhelekileyo isetyenziselwa ukusasaza kunye neenkonzo zevidiyo ze-intanethi.
