VOB → MPG

Yeah, uye ndiyo nhanho yakanyanya. VOB uye MPG vanobatana neimwe yeiyo yakadzika yekuchengetera nharaunda, saka mavhidhiyo uye maaudio ma streams akakopwa kuburikidza nebyte-by-byte uye chete mudziyo wemudziyo unonyorwazve. Hapana chinhu chinodecoding uye hapana chinhu chinodzokororwa, saka faira refeature-length rinopera pasi peminitsi kwete hafu yeawa, nemhando yezvakagadzirwa zvakafanana nechigadzirwa. VOB ndiro Video Object chivharo yakawanikwa muVIDEO_TS folder yese DVD - MPEG-2 chirongwa mvura ne DVD-yakazvimirira navigation data akawedzera. MPG ndiyo imwe MPEG program stream se.mpeg — the three-letter extension is a DOS-era truncation, not a different format.

Hapana, uye iyi ndiyo imwe yezvikonzero zviri nani zvekufambisa. VOB mudziyo une yakapusa faira-file ceiling iyo yakareba kana yakakwira-bitrate rekodhi inoenda zvakananga, izvo ndizvo chaizvo nei makamera ekare achisvika sechikamu1, chikamu2, chikamu3. MPG haina muganho wakaenzana, saka mapikicha anogona kudzokera kune imwe file. VOB inonzi yakaparadzwa pakati pemafaera, inogona kunge iri CSS-encrypted, uye inotakura mapakeji ekufamba ayo anokonzera kusagadzikana kwevatambi vezvinangwa zvakasiyana.

Hazvigone kugara zvichisarudzwa, nekuti MPG haina soft-subtitles stream kuti ichengete. Kune nzira mbiri dzekubuda: nyora iwo muvhidhiyo panguva yekushandura, izvo zvinovaita kuti varambe uye vasingaite, kana kutumira kunze sezvimwe.srt pamwe ne MPG kuti mutambi atore. Mugadziri anotaura iwe izvo zvaakaita kupfuura kubvisa iwo zvisina kunaka. MPG anotora pazuva MPEG-2 kurambidzwa — heavy bitrate, interlacing, hapana soft subtitles — pamwe nekushaikwa kwezviviri kusvikira imwe format.

Zviri pachena kuti DRM. Zvimwe VOB mafaera anovharwa pabitstream level nekutengesa kana software iyo yakaburitsa iwo, uye yakavharwa mvura haigone kugadziriswa nedu kana nechinhu chero chipi zvacho pasina chiratidzo chelicensing. Mafaira aunenge wanyora, wakatumira kunze kana wakarodha pasi zvisingadzivirirwe zvinoshandura zvakajairika; chibvumirano chekutenga chisiri, uye hapana mushanduri anogona kuvimbisa zvakasiyana.

Kana chete kana chigadzirwa chine chinangwa chacho. Mafomati maviri aya anobva pamwechete pre-H.264 era, saka hapana kushandura kunotenga mhedzisiro, mhando kana kuchengetedzeka kwezuva nezuva — kunotenga kuenderana neimwe chigadzirwa. Kana chinangwa chiri kuchengetedza mavhidhiyo anogoneswa kwenguva yakareba, shandura kuita chigadzirwa chitsva chisina kugadziriswa.

Yeah — chero audio track mu VOB (munyori wemashoko, dzimwe rurimi, descriptive audio) inochengetwa mu MPG kana chinangwa chemudziyo chinotsigira multi-stream audio. MKV neMOV zvinodzora maaudio tracks asina muganho; MP4 inotsigira akawanda asi mamwe mahardware maplayers anoona chete track 1; WebM inorambidzwa kune imwe Opus / Vorbis track.

Soft subtitle (zvinhu zvinosarudzwa) zvinorarama kana MPG zvichigona kutakura iwo: MKV ine SRT, ASS, SSA, PGS, VobSub zvakananga; MP4 ine mov_text chete (yakavharwa fomati). Kushandura MKV ine ASS subs kune MP4 kunoita kuti zvive mov_text kana kuisa iwo. Hardsubs (yakavharwa muvhidhiyo) inoramba ichienda.

Chitsauko che metadata chinoshandura pakati pe VOB ne MPG kana zvese zviwanikwa zvichitsigira chitsauko che atom (MKV, MP4, MOV). WebM inochengeta chitsauko muMatroska-inowirirana block, saka MKV <-> WebM chitsauko chinofamba-famba zvakanaka. AVI haina chitsauko che spec, saka kushandura AVI kuenda ku MPG kunogadzira faira risina chitsauko kana iwe usingawedzera mamarkers nemwoyo wako.

MKV ndiyo chete mainstream container iyo inochengeta zvakananga zvakaiswa mafaera (TTF fonts ye ASS subs, JPG cover art, fan-translated PDF inserts). Kubva ku VOB kuenda ku MPG kunobvisa izvi zvakaiswa kana MPG hachisi MKV — elementary streams inoshandura, asi zvakaiswa payload zvinogara munzvimbo yekubva. Tenga VOB se backup kana iwe uchida kuvimba nezvinyorwa zvakaiswa.

Default codec inosarudza kusangana neMPG container zvakachengeteka: MKV defaults kune H.265 (HEVC) kune yakanakisa kumanikidza; MP4 defaults kune H.264 kune yakakura kwazvo chikuva rutsigiro; WebM defaults kune VP9; AVI inoshandisa MPEG-4 ASP (DivX / Xvid lineage). Kubvisa kuburikidza neyakakwira codec dropdown — AV1 iripo ye MKV / WebM uko iwe uchida kumanikidza kwepamusoro uye unogona kumirira nekunyora. MPG ndiyo kusvikira DVD authoring software, vanopfuura camcorders uye kutumira ingestion zvinhu kubvuma, saka inogara zvakanakira kune avo pipelines.

HDR static metadata (HDR10 mastering kuratidzwa mitengo, max content light level) inoenda kusvika ku MPG kana zvese zvidimbu uye yakasarudzwa codec ichiita (HEVC, AV1 mu MKV / MP4). Dolby Vision isiri nyore - DV profile 5 / 7 / 8.1 mu VOB inoramba ichirarama chete mu MKV neHEVC; kushandura kune MPG chidimbu chisina kutakura DV layer inoparadza HDR10.
