WMV ukuba WebM Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Xa i WMV ne WebM 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 WebM isiqulatho kwaye kutshintsha kuphela umgqomo. I-remux ye-1 GB WMV kwi WebM 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. I-WebM imiselwe ukuba incinci: i-VP8 okanye i-VP9 ividiyo (i-AV1 ngoku isasazeka) ene-Vorbis okanye i-Opus isandi, akukho nto enye.

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

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 WebM. WMV yiWindows Media Video, iMicrosoft's ASF-based format ukusuka kwixesha leWindows XP.

Ndingazifaka njani izihloko ezingaphantsi ezikhethiweyo xa ifayili ikwi WebM?

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. WebM ithatha i-subtitles njenge-stream yabo ekhethiweyo, ngoko ke emva kokuguqula ungadibanisa i-SRT track imboniso ingatshintshwa, itshintshwe okanye iphinde iguqulwe.

Ingaba i WebM iyadlala kwisikhangeli xa i WMV ayiyidlala?

Ewe, kwaye oko kuqhelekileyo isizathu esipheleleyo sokuguqula. A WMV efakwe kwiphepha le web okanye ibonisa umdlali olahlwayo okanye iforce ulwaleko, kuba ibrowser ayithuthinga i decoder kuyo. WebM idlala kwilayini esuka kwi HTML5 eqhelekileyo isixhobo sevidiyo ngaphandle koplugin kwaye akukho sicelo sengaphandle. I-WebM idlala ngokusemthethweni kwi-browser nganye ekhoyo ngoku ngaphandle kokufaka, ngaphandle kwelayisensi yemali, ngaphandle kokubonisa ipateni, eyenza ukuba imiselwe kwividiyo efakwe kwi-web.

Ingaba kufanelekile ukutshintsha i WMV yoshicilelo oludala ukuya kwi WebM?

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 WebM 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-WebM?

Ewe - yonke i-audio track kwi WMV (umbono womlawuli, iilwimi ezitshintshiweyo, i-audio echazayo) igcinwa kwi WebM 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. I-WebM yinxalenye encinci eqinileyo ye-Matroska epapashwe yiGoogle ngo-2010 ekhethekileyo ukunika i-HTML5 ividiyo isiqulathi seefayili esingenazo iirhafu.

Ingaba iingoma zesicatshulwa zigcinwa xa uguqula WMV ukuya ku WebM?

Izihloko eziphantsi ezicocekileyo (iingoma ezikhethiweyo) zihlala zikhona xa WebM 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 WebM igcina abaphawuli besahluko / ulawulo olufana ne-DVD?

I-metadata yesichazi-magama idlulisa phakathi kwe-WMV ne-WebM 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-WebM 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 WebM?

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 WebM ushiya ezi fayili zifakiwe xa i-WebM 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-WebM kwimveliso ngokumiselweyo?

I-codec emiselweyo ikhethiwe ukuhambelana ne WebM 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-WebM ilungile naphi na ngaphandle kwebrowser - abahleli bevidiyo, ii-galeri zefowuni eziqhelekileyo kunye neSmart TVs ziyihoyi kakhulu.

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

I-HDR metadata ehlala njalo (i-HDR10 ibonisa amaxabiso aphezulu, umphakamo ophezulu wokukhanya kwezinto eziquletheyo) ihamba phantsi ukuya kwi-WebM 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-WebM isiqulatho esingathwali umbala we-DV ihamba phantsi ukuya kwi-HDR10.

Ingaba i-WMV ukuya kwi-WebM igcina i-framerate eguqukayo (VFR)?

MKV ne WebM zirekhoda i-frame nganye yexesha elipheleleyo kunye nokuphatha i-VFR ngokusemthethweni, ngoko ke i-WMV VFR ihlala kwi-WebM yale fomati ngaphandle kokuphindaphinda. I-MP4 igcina i-timestamps ngokusemthethweni kodwa abanye abadlali bakholelwa ukuba i-CFR; umguquli ubonisa "ubunzima be-CFR" ukutshintsha okubuyisela i-VFR WMV ukuya kwi-24 / 30 / 60 fps WebM kwiinjongo ezinomngcipheko.

WMV

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