MKV ukuba WebM Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Xa i MKV 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 MKV kwi WebM ihlala igqiba kwimizuzu eyi-5-15 ngaphandle kokufumana inzuzo yomgangatho. MKV yi-codec-agnostic: H.264, HEVC, VP9 ne-AV1 ividiyo ihlala ikhululekile ecaleni kwe-AAC, FLAC, Opus, DTS okanye i-Dolby audio kwifayili enye. I-WebM imiselwe ukuba incinci: i-VP8 okanye i-VP9 ividiyo (i-AV1 ngoku isasazeka) ene-Vorbis okanye i-Opus isandi, akukho nto enye.

Ingaba i MKV ingaguqulwa ibe yi WebM ngaphandle kokubuyisela umbhalo ofihlakeleyo wevidiyo?

Ewe, kwaye yindlela ekhawulezayo. MKV ne WebM zisebenzisa ukwakhiwa kwebhokisi ephantsi, ngoko ividiyo kunye nesandi zikhopiwe kwi-byte-kwi-byte kwaye kuphela isiqulathi seefayili sibhalwe kwakhona. Akukho nto ikhowudi kwaye akukho nto iphinde icinezelwe, ngoko ifayile yobude bempawu igqiba ngaphantsi kwemizuzu endaweni yeyure enye, ngemveliso ehambelanayo yobunjani bomthombo. MKV yi Matroska, ibhokisi evulekileyo eyenziwe ngo 2002 ngaphandle kweengxaki zonikezelo lwelayisensi kunye nokungaphelelanga kwinto engayigcinayo. I-WebM yinxalenye encinci eqinileyo ye-Matroska epapashwe yiGoogle ngo-2010 ekhethekileyo ukunika i-HTML5 ividiyo isiqulathi seefayili esingenazo iirhafu.

I MKV yam inezinto ezininzi ezidlala umculo - ngaba zonke ziya kuhlala zikhona kwi WebM?

Ayithembekanga. MKV igcina imijelo emininzi yesandi njengemizila yohlobo lokuqala, kodwa WebM uxhaso lokudlala ngaphezulu kwemizila yokuqala ayihambelani, ngoko abadlali abaninzi baya kutyhila kuphela enye. Khetha imizila oyifunayo phambi kokuguqula; abanye bangcono ukutywina kwifayile zabo ezikhethekileyo kunokuba bashiye kwisiqulathi seefayili esifihlayo. I-MKV yindawo yokugcina ekhethiweyo kuba igcina iingoma zesandi ezingaphelelanga, izihloko eziphantsi ezicocekileyo, abaphawuli besiqendu kunye nobugcisa bokuqhoboshela kwifayili enye. I-WebM ilungile naphi na ngaphandle kwebrowser - abahleli bevidiyo, ii-galeri zefowuni eziqhelekileyo kunye neSmart TVs ziyihoyi kakhulu.

Ingaba i WebM iyadlala kwisikhangeli xa i MKV ayiyidlala?

Ewe, kwaye oko kuqhelekileyo isizathu esipheleleyo sokuguqula. A MKV 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 i-audio enezithotho ezininzi izakuhlala iphila ukuguqulwa kwe-MKV ukuya kwi-WebM?

Ewe - yonke i-audio track kwi MKV (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.

Ingaba iingoma zesicatshulwa zigcinwa xa uguqula MKV 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 MKV ukuya ku WebM igcina abaphawuli besahluko / ulawulo olufana ne-DVD?

I-metadata yesichazi-magama idlulisa phakathi kwe-MKV 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 MKV 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 MKV ukuya kwi WebM ushiya ezi fayili zifakiwe xa i-WebM ayiyiyo i-MKV — i-elementary streams iguqula, kodwa umthwalo odityanisiweyo uhlala kummthombo. Gcina i-MKV 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-HDR (HDR10, Dolby Vision) ihlala njani MKV 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-MKV ihlala kuphela kwi-MKV ene-HEVC; ukutshintsha kwi-WebM isiqulatho esingathwali umbala we-DV ihamba phantsi ukuya kwi-HDR10.

Ingaba i-MKV 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-MKV 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 MKV ukuya kwi-24 / 30 / 60 fps WebM kwiinjongo ezinomngcipheko.

Kutheni i-WebM ifayili yam incinci / ikhulu kune-MKV emva kokuguqulwa?

I-remux ye-codec efanayo ivelisa ubungakanani obufanayo (i-container overhead ihluka nge-0.1-2%). Utshintsho lwe-codec lunokutshintsha ubungakanani nge-50% okanye ngaphezulu: H.264 ukuya kwi-H.265 ngokuqhelekileyo iqulethe ifayili kwinqanaba elifanayo lomgangatho wokubona; H.264 ukuya kwi-AV1 iqulethe kwakhona kwi-preset ecocekileyo. Ukusuka kwi-bitrate ephezulu MKV (Blu-ray rip) ukuya kwi-bitrate ephantsi WebM (ukukhuphela kwi-web) yisizathu esiqhelekileyo sokuhla okuphezulu.
