WebM ukuba MPG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Xa i WebM ne MPG 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 MPG isiqulatho kwaye kutshintsha kuphela umgqomo. I-remux ye-1 GB WebM kwi MPG ihlala igqiba kwimizuzu eyi-5-15 ngaphandle kokufumana inzuzo yomgangatho. I-WebM imiselwe ukuba incinci: i-VP8 okanye i-VP9 ividiyo (i-AV1 ngoku isasazeka) ene-Vorbis okanye i-Opus isandi, akukho nto enye. Okuqulethwe yi-MPEG-1 okanye i-MPEG-2 ividiyo ene-MP2 umsindo; ukudibanisa nokwakhiwa kwe-GOP kufana ne-.mpeg ifayili.

Yintoni eyenza i-subtitle tracks kwifayili yam WebM?

Ayikwazi ukuhlala ikhethiwe, kuba MPG ayinayo i-soft-subtitle stream ukubeka i-subtitles. Zikhona iindlela ezimbini zokuphuma: ukutshabalalisa kwividiyo ngexesha lokuguqula, okwenza ukuba zihlala zihlala kwaye zingatshintshwa, okanye urhweba ngaphandle njenge.srt eyahlukileyo ecaleni kwe MPG ukuze umdlali alayishe. Umguquli uthetha ukuba yintoni eyayenza kunokuba ikhuphe ngokucokisekileyo. MPG ifumana yonke i MPEG-2 imida - i-bitrate enzima, uthungelwano, akukho sihloko esicocekileyo - kunye nokungaqhelekanga kweendawo ezimbini zokukhupha ifomati enye.

Ingaba i MPG igcina ngaphezulu kwengoma enye yesandi?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe WebM. MPG iphatha yonke imijelo yesandi njengento ephambili, ngoko udidi lwesivakalisi sokuqala, i-dub kunye nomlawuli wengxelo ingaphila kwifayile enye nomdlali otshintshela phakathi kwabo kwisicelo. MPG yi DVD yoshicilelo lwesoftware yolubanzi, i-camcorders edala kunye nezixhobo zokusasaza ukutya ziyazi, ngoko ihlala isetyenziswa kwezi ntambo.

Ndingayifaka njani ifayili kwiphepha le-web emva kokuguqula i-WebM ibe yi-MPG?

Ayi ngqo. WebM idlala umgca kwisixhobo sokukhangela yonke; MPG ayisebenzi, ngoko ke iphepha elidibanisa ibuyela umva kwikhonkco lokulayisha okanye isakhelo somdlali ongenanto. Ukuba ifayile icwangciswe kwiwebhusayithi, gcina i WebM kwi-web kwaye uthathe i MPG njenge-archive okanye uhlela ikopi.

Kutheni ndiyiguqula i WebM ibe yifomati edala njenge MPG?

Kuba isixhobo esininzi sekhompyutha asizange sifunde nantoni na entsha kwaye asizukufunda. Abadlali be DVD, iiyunithi zemoto eziphambili, iimo zokubukela i-camcorder, imboniselo yeshishini kunye nezixhobo ezininzi zosasazo lweemveliso zixhasa MPG kwaye akukho nto enye. Uguqulelo luya kugqiba inqanaba ezantsi kwimpumelelo, ithengiswe ukutshintshela ukusebenza kwisixhobo esingakho enye indlela yokukhetha.

Ingaba i-audio enezithotho ezininzi izakuhlala iphila ukuguqulwa kwe-WebM ukuya kwi-MPG?

Ewe - yonke i-audio track kwi WebM (umbono womlawuli, iilwimi ezitshintshiweyo, i-audio echazayo) igcinwa kwi MPG 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-MPG ifana nenkqubo ye-MPEG ejikelezayo njenge-.mpeg — uluhlu lweeleta ezintathu luyi-DOS-era truncation, hayi ifomati eyahlukileyo.

Ingaba iingoma zesicatshulwa zigcinwa xa uguqula WebM ukuya ku MPG?

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

I-metadata yesichazi-magama idlulisa phakathi kwe-WebM ne-MPG 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-MPG yenza ifayili engachazi-magama ngaphandle kokuba udibanisa abaphawuli ngesandla.

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

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 WebM ukuya kwi MPG ushiya ezi fayili zifakiwe xa i-MPG ayiyiyo i-MKV — i-elementary streams iguqula, kodwa umthwalo odityanisiweyo uhlala kummthombo. Gcina i-WebM njengengxelo yangaphambili ukuba uxhomekeke kwifonti ezifakelweyo.

Yeyiphi i-codec esetyenziswa yi-MPG kwimveliso ngokumiselweyo?

I-codec emiselweyo ikhethiwe ukuhambelana ne MPG 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 WebM ukuya ku MPG?

I-HDR metadata ehlala njalo (i-HDR10 ibonisa amaxabiso aphezulu, umphakamo ophezulu wokukhanya kwezinto eziquletheyo) ihamba phantsi ukuya kwi-MPG 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-WebM ihlala kuphela kwi-MKV ene-HEVC; ukutshintsha kwi-MPG isiqulatho esingathwali umbala we-DV ihamba phantsi ukuya kwi-HDR10.

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

MKV ne WebM zirekhoda i-frame nganye yexesha elipheleleyo kunye nokuphatha i-VFR ngokusemthethweni, ngoko ke i-WebM VFR ihlala kwi-MPG 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 WebM ukuya kwi-24 / 30 / 60 fps MPG kwiinjongo ezinomngcipheko.
