M4V ukuba VOB Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Xa i M4V ne VOB 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 VOB isiqulatho kwaye kutshintsha kuphela umgqomo. I-remux ye-1 GB M4V kwi VOB ihlala igqiba kwimizuzu eyi-5-15 ngaphandle kokufumana inzuzo yomgangatho. Ngokusisiseko i-M4V yi-MP4 — H.264 okanye HEVC nge-AAC — ene-Apple FairPlay DRM ekhethiweyo kunye ne-iTunes isithuba se-metadata. 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.

Kutheni ndiyiguqula i M4V ibe yifomati edala njenge VOB?

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 VOB kwaye akukho nto enye. Uguqulelo luya kugqiba inqanaba ezantsi kwimpumelelo, ithengiswe ukutshintshela ukusebenza kwisixhobo esingakho enye indlela yokukhetha. I-VOB igcina yonke i-DVD yothutho olusebenzayo - ii-angles ezininzi, iilwimi ezininzi zesandi kunye nengoma yomxholo ophantsi zonke zihlala ngaphakathi.

Ingaba i-audio enezithotho ezininzi izakuhlala iphila ukuguqulwa kwe-M4V ukuya kwi-VOB?

Ewe - yonke i-audio track kwi M4V (umbono womlawuli, iilwimi ezitshintshiweyo, i-audio echazayo) igcinwa kwi VOB 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-VOB yi Video Object Container efumaneka kwi VIDEO_TS ulawulo lwe DVD nganye — i MPEG-2 inkqubo yokuhamba nge DVD-ekhethekileyo yokukhangela idata efakwe.

Ingaba iingoma zesicatshulwa zigcinwa xa uguqula M4V ukuya ku VOB?

Izihloko eziphantsi ezicocekileyo (iingoma ezikhethiweyo) zihlala zikhona xa VOB 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 M4V ukuya ku VOB igcina abaphawuli besahluko / ulawulo olufana ne-DVD?

I-metadata yesichazi-magama idlulisa phakathi kwe-M4V ne-VOB 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-VOB yenza ifayili engachazi-magama ngaphandle kokuba udibanisa abaphawuli ngesandla.

Yintoni malunga neziqulathi zeefayili ze-MKV (ifonti, umzobo wesiqulathi seefayili) xa usiya kwi M4V ukuya kwi VOB?

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 M4V ukuya kwi VOB ushiya ezi fayili zifakiwe xa i-VOB ayiyiyo i-MKV — i-elementary streams iguqula, kodwa umthwalo odityanisiweyo uhlala kummthombo. Gcina i-M4V njengengxelo yangaphambili ukuba uxhomekeke kwifonti ezifakelweyo.

Yeyiphi i-codec esetyenziswa yi-VOB kwimveliso ngokumiselweyo?

I-codec emiselweyo ikhethiwe ukuhambelana ne VOB 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-VOB ihlukaniswe phakathi kweefayili, ingafihliwe nge-CSS, kwaye ihambisa iipakeji zokhangelo eziphazamisa abadlali abafunayo.

I-HDR (HDR10, Dolby Vision) ihlala njani M4V ukuya ku VOB?

I-HDR metadata ehlala njalo (i-HDR10 ibonisa amaxabiso aphezulu, umphakamo ophezulu wokukhanya kwezinto eziquletheyo) ihamba phantsi ukuya kwi-VOB 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-M4V ihlala kuphela kwi-MKV ene-HEVC; ukutshintsha kwi-VOB isiqulatho esingathwali umbala we-DV ihamba phantsi ukuya kwi-HDR10.

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

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

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

Ingaba i-M4V ukuya kwi-VOB iguqula i-4K / 8K / 60fps iqulethe?

Ewe ukuya kwi-8K (7680x4320) kwi-Premium. Umphakamo okhululekileyo uphatha i-4K (3840x2160) ukuya kwi-1 GB yefayili. I-pure remuxes (i-codec efanayo edlulayo) ye M4V enkulu kwi-VOB imiselwe yi-disk I/O, hayi i-CPU — i-30 GB M4V iqhelekileyo i-remuxes kwi-VOB ngaphantsi komzuzu ngaphandle kokuxhomekeka kwi-resolution. I-re-encodes i-scale nge-pixel count.

Ingaba i-M4V yam ifayile ifihlakeleyo ngexesha lokuguqulwa kwe-VOB?

Ewe — iifayile ezilayishwe phezulu M4V ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu yokuphela. Asizukuzijonga, sizigcine, sizigcine, okanye sizonwabele iziqulatho. Bona /privacy/ kwifestile yokugcina i-data. Inkqubo yokuguqula iqhuba kwihardware esilawulayo ukusuka ekupheleni ukuya ekupheleni; akukho qela lesithathu le-APIs lifumana ifayili yakho. I-M4V igcina abaphawuli besiqendu, umsebenzi wobugcisa kunye nengoma yesihloko esingaphantsi kwisimo i-Apple TV app ilindeleyo, eyona MP4 iqhelekileyo ihlala ilahlekelwa yiyo.

M4V

I-M4V yifomati yefayile yevidiyo ephuhliswe nguApple. Iyafana neMP4 kwaye iqhele ukusetyenziselwa ukudlala ividiyo kwizixhobo zeApple.

VOB

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