Guqula WMV ukuba 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.

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. Ngokusisiseko i-M4V yi-MP4 — H.264 okanye HEVC nge-AAC — ene-Apple FairPlay DRM ekhethiweyo kunye ne-iTunes isithuba se-metadata.

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.

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.

Iifayile ze WMV zifihliweyo kwinqanaba le bitstream yindawo yokurhweba okanye isoftware ekhupha ifayile, kwaye umsinga ofihliweyo awunakucodwe sisi okanye ngantoni na ngaphandle kwesitshixo selayisensi. Iifayile ozirekhode, ozirhwebe ngaphandle okanye ozikhuphele ezantsi azikhuselwanga ziguqula ngokuqhelekileyo; ukuthengiswa kwelayisensi akuyi kwenza njalo, kwaye akukho mguquli uthembekileyo okwaziyo ukuthembisa okuthile. 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.

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.

Ewe - uguqulelo olusisiseko WMV → M4V lukhululekile ngaphandle kobhaliso. I-Premium idibanisa umda ophezulu wobungakanani befayili nganye, abasebenzi abangaphezulu beqela elifanayo, kwaye isusa ii-ad.

Ii-akhawunti ezikhululekileyo: ukuya kuthi ga kwi-100 MB ngefayili nganye ye WMV. I-Premium: ihlala i-1 GB ngefayili nganye, kuxhomekeke kuhlobo lombhalo we WMV. Iifayile ezinkulu kakhulu zihlukaniswa zibe zii-chunks kwi-server-side xa i-M4V ivumela.

Uguqulelo lugcina yonke i-informatios enokuthi imele i-WMV ne-M4V. Iimpawu ezikhethekileyo zefomati ezingenakuxhaswa yi-M4V (umzekelo, i-data ye-vector kwi-raster output, ii-formula kwi-plain-text output) zi-rasterized okanye zi-stripped — bona iziphawuli ezikhethekileyo zefomati kwiphepha le-result.

Ewe — susa iifayile ezininzi WMV kummandla wokulayisha kwaye zifololwe ngokuthe tye. I-Premium inemisebenzi emininzi ethe tye; kwi-50-file batch le yi-difference phakathi kwemizuzu nemizuzu.

Ewe - i-UI iphendula kwaye inkqubo yokuguqula iqhuba kwicala leseva, ngoko ii-mobile devices zikhuphela-za-zikhuphele njenge-desktops. I-iOS kunye ne-Android browser files pickers (ikhamera ijikeleza, Iifayile zeapp) zisebenza ekupheleni-kwi-kuphela.
