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.

Kutheni le nto ifayili yam VOB ayiphumelelanga ukutshintshela kwi M4V?

Iifayile ze VOB zifihliweyo kwinqanaba le bitstream yindawo yokurhweba okanye isoftware ekhupha ifayile, kwaye umjelo 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.

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.

VOB

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