VOB ukuba M4V Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Xa i VOB 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 VOB kwi M4V ihlala igqiba kwimizuzu eyi-5-15 ngaphandle kokufumana inzuzo yomgangatho. I-VOB igcina i-MPEG-2 video, AC-3 okanye i-PCM audio, kunye ne-DVD subpicture subtitle streams, ihlukaniswe ibe yi-1 GB yecandelo nge-DVD spec. Ngokusisiseko i-M4V yi-MP4 — H.264 okanye HEVC nge-AAC — ene-Apple FairPlay DRM ekhethiweyo kunye ne-iTunes isithuba se-metadata.

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

Iya kwenza ukuba awuyi-deinterlace, kwaye VOB 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. I-VOB yi Video Object Container efumaneka kwi VIDEO_TS ulawulo lwe DVD nganye — i MPEG-2 inkqubo yokuhamba nge DVD-ekhethekileyo yokukhangela idata efakwe.

I-VOB yam yokurekhoda ihlukaniswe ibe ziinxalenye ezilinganisayo - ngaba i-M4V inemida efanayo?

Hayi, kwaye le yenye yezona zizathu zilungileyo zokushenxisa. I VOB isiqulathi siqulethe ifayile enye esebenzayo ethe tyaba eyenza ushicilelo olude okanye oluphezulu-bitrate luqhube ngokuthe ngqo, oko kukuthi, kutheni ushicilelo oludala lufika njengenxalenye1, ingxenye2, ingxenye3. M4V ayinalo umda ofanayo, ngoko ke iinxalenye zingadityaniswa kwakhona kwifayile enye eqhubekayo. I-VOB ihlukaniswe phakathi kweefayili, ingafihliwe nge-CSS, kwaye ihambisa iipakeji zokhangelo eziphazamisa abadlali abafunayo.

Ingaba kufanelekile ukutshintsha i VOB yoshicilelo oludala ukuya kwi M4V?

Ukuba ufuna ukugcina into, ewe. VOB 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. 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-audio enezithotho ezininzi izakuhlala iphila ukuguqulwa kwe-VOB ukuya kwi-M4V?

Ewe - yonke i-audio track kwi VOB (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 VOB 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 VOB ukuya ku M4V igcina abaphawuli besahluko / ulawulo olufana ne-DVD?

I-metadata yesichazi-magama idlulisa phakathi kwe-VOB 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 VOB 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 VOB ukuya kwi M4V ushiya ezi fayili zifakiwe xa i-M4V ayiyiyo i-MKV — i-elementary streams iguqula, kodwa umthwalo odityanisiweyo uhlala kummthombo. Gcina i-VOB 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 VOB 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-VOB ihlala kuphela kwi-MKV ene-HEVC; ukutshintsha kwi-M4V isiqulatho esingathwali umbala we-DV ihamba phantsi ukuya kwi-HDR10.

Ingaba i-VOB ukuya kwi-M4V igcina i-framerate eguqukayo (VFR)?

MKV ne WebM zirekhoda i-frame nganye yexesha elipheleleyo kunye nokuphatha i-VFR ngokusemthethweni, ngoko ke i-VOB VFR ihlala kwi-M4V 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 VOB ukuya kwi-24 / 30 / 60 fps M4V kwiinjongo ezinomngcipheko.

Kutheni i-M4V ifayili yam incinci / ikhulu kune-VOB 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 VOB (Blu-ray rip) ukuya kwi-bitrate ephantsi M4V (ukukhuphela kwi-web) yisizathu esiqhelekileyo sokuhla okuphezulu.

VOB

I-VOB (i-Video Object) yifomati yesikhongozeli esetyenziselwa ividiyo yeDVD. Ingaqulatha ividiyo, iaudio, izihlokwana, kunye neemenyu zokudlala kweDVD.
