MPG → VOB

Yeah, uye ndiyo nhanho yakanyanya. MPG uye VOB 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. MPG ndiyo imwe MPEG program stream se.mpeg — the three-letter extension is a DOS-era truncation, not a different format. VOB ndiro Video Object chivharo yakawanikwa muVIDEO_TS folder yese DVD - MPEG-2 chirongwa mvura ne DVD-yakazvimirira navigation data akawedzera.

Yeah. MPG haina kushandiswa kweiyo soft-subtitle track, saka subtitle ye MPG zvikamu zvaifanira kusvibiswa mufananidzo kana kuendeswa seyakazvimiririra sidecar faira. VOB inotakura subtitle sezvavanosarudza, saka mushure mekushandurwa unogona kubatanidza SRT track iyo muverengi anogona kuvhura, kudzima kana kushandura.

VOB ichengeta mabhuku semetadata ebhokisi, saka bhuku rinogona kuendeswa nechikamu sezviri mukati, kwete nekucheka mutsara wekumhanya. MPG haina chero nzvimbo yekuisa iyo ruzivo, saka kana iyo nzvimbo yakatakura nebhuku rebhuku, yaive mu file sidecar - shandisa iyo converter uye inonyorwa mu VOB. VOB inochengeta yose DVD payload - akawanda angles, akawanda audio rurimi uye subtitle matracks vese kurarama mukati.

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. MPG anotora pazuva MPEG-2 kurambidzwa — heavy bitrate, interlacing, hapana soft subtitles — pamwe nekushaikwa kwezviviri kusvikira imwe format. VOB inonzi yakaparadzwa pakati pemafaera, inogona kunge iri CSS-encrypted, uye inotakura mapakeji ekufamba ayo anokonzera kusagadzikana kwevatambi vezvinangwa zvakasiyana.

Yeah — chero audio track mu MPG (munyori wemashoko, dzimwe rurimi, descriptive audio) inochengetwa mu VOB 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 VOB 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 MPG ne VOB 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 VOB 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 MPG kuenda ku VOB kunobvisa izvi zvakaiswa kana VOB hachisi MKV — elementary streams inoshandura, asi zvakaiswa payload zvinogara munzvimbo yekubva. Tenga MPG se backup kana iwe uchida kuvimba nezvinyorwa zvakaiswa.

Default codec inosarudza kusangana neVOB 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.

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

MKV neWebM anonyora mazita enguva enguva uye anodzora VFR zvakananga, saka MPG VFR inorarama mu VOB eaya mafomati pasina kudzokorora. MP4 inochengeta mazita enguvawo asi vamwe vatambi vanofunga CFR; mushanduri unopa "force CFR" toggle iyo inodzokorora VFR MPG kusvika 24 / 30 / 60 fps VOB kune zvinonetsa zvinangwa.
