VOB → MPG

He, ā, ko te huarahi tere. VOB me MPG e tiritiri ana i te hanganga kāwai ā-roto ōrite, kia tārua ai ngā aho whakaata me te oro oro puta noa i te paepae-ki-paepae, ā, ka tāruatia anō anake te whākōkī kāwai. Kāore he mea whakakōkī, ā, kāore he mea whakawhāiti anō, kia oti ai tētahi pūranga āhuatanga roa i raro i te minu i te wā o te wā kotahi, me te huaputa ā-whakahaere ki te pūtake. Ko te VOB te taiwhanga Video Object e kitea ana i roto i te pūrākau VIDEO_TS o ia DVD — he rerenga papatono MPEG-2 me te tāpiri i te raraunga whakatere DVD-mātau. Ko te MPG te rerenga papatono MPEG ōrite ki te.mpeg — ko te whakaroatanga tuhipoka e toru he whakaroatanga o te wā DOS, ehara i te hanga rerekē.

Kāore, ā, ko taua tētahi o ngā take pai ake hei neke. He tauine pūtahi-pūtahi te VOB kōwae e haere tika ana ki ngā pūkete roa, ki ngā pūkete bitrate-high rānei, ko te take i tae ai ngā tāurunga tahito hei wāhanga1, wāhanga2, wāhanga3. MPG kāore he tepe ōrite, nō reira ka taea te whakakotahi anō i ngā wāhanga ki tētahi pūkete tūturu. Ka wehea te VOB i waenganui i ngā pūranga, ka taea te whakawaehere i te CSS, ā, ka mau ngā pakiaka whakatere e whakamātau ana i ngā kaiwhakaari taketake.

Kāore e taea te tīpako, nā te mea kāore he pūwhitinga pūāhua-whakaahua mārō a MPG hei pupuri i a rātau. E rua ngā ara kia puta mai: ka whakamārō i a rātau ki roto i te ataata i te wā o te tahuritanga, e noho ai rātau ki te noho tonu, ki te kore āhua, ki te whakawātea rānei i a rātau hei.srt motuhake i te taha o te MPG mō te pūpāho hei whakarewa. E kī ana te kaiwhakarere ki a koe he aha i mahi ai, kaua e whakawātea i a rātau. Ka tukua e MPG ngā whakawhāiti katoa o MPEG-2 — te mokatere bit taumaha, te whakawhāititanga, kāore he whakarārangi māmā — tae atu ki te whakawāteatanga o ngā whakaroatanga e rua mō tētahi hanga.

Tata tonu ki te DRM i ngā wā katoa. Ko ētahi VOB ngā pūranga e whakawaeheretia ana i te taumata bitstream e te puna, i te pūmanawa rānei i tukuna ai rātou, ā, kāore e taea te whakawaehere i tētahi rerenga whakawaeheretia e tātau, e tētahi atu rānei me te kore te kī ā-whakahaere. Ko ngā pūranga i whakahuatia e koe, i whakawātea, i whakawāteatia rānei i te whakarerekētanga kāore i te parea; kāore e taea e te hoko ā-pūmanawa, ā, kāore e taea e te kaiwhakarere te whakaū i tētahi atu mea.

Ahakoa rā, mēnā e hiahiatia ana e tētahi wāhanga motuhake o ngā pūrere te ūnga. Ko ngā āhuahira e rua e puta mai ana i te wā o mua-H.264 ōrite, nō reira kāore te tahuritanga e hokona ana i te tōtika, te āhuatanga, te whakaūtanga rānei i te wā o muri ake - e hokona ana i te ōritetanga ki tētahi pūrere motuhake. Mēnā ko te take kia mau ai te pūwhitinga e whakamahia ana i te wā roa, ka tahuri ki tētahi kāwai o nāianei, kaua e pāpāho.

E whakawhirinaki ana ki te MPG kōpaka. MP4 te tīpako ki H.264 mō te tautoko pānui whānui rawa puta noa i ngā pūkoro, ngā kiritaki, me ngā Smart TV. MKV te tīpako ki H.265 / HEVC mō te haurua o te rahi o te pūkete i te āhuatanga ōrite. WebM te tīpako ki VP9. Ka whakawātea ngā kōwhiringa hōhonu i te kōwhiringa pūoko mēnā e hiahiatia ana kia whakawāteatia.

Inā VOB me MPG e tiritiri ana i tētahi pūkōrero oro (hei tauira, e mau ana rāua i te AAC), ka whakawāteatia anō te oro me te kore whakawaenga - ōrite te iti. Ki te rerekē ngā pūkōrero, ka whakawaengatia te oro ki te AAC / Opus / Vorbis i runga anō i te mea e tautoko ana te MPG kāwai. Ka tiakina te oro-maha (whakaaro, reo whirinoa).

Mā te pūmau, ā, — he 24fps VOB e noho ana i te 24fps i roto i MPG; he 60fps VOB e noho ana i te 60fps. Mēnā e hiahiatia ana e koe kia huri i te mokatere (hei tauira, i whakawāteatia te 29.97 → whakawhāiti 30, 60 rānei → 30 mō ngā tepe whakarewa), ka whakahaeretia e te kōwhiringa rārangi te 3:2 whakatata, te whakawāteatanga, me te whakakotahitanga rārangi i te whakawhitinga waehere ōrite.

He rite tonu te whakarerekētanga o te pūkōrero (VOB H.264 → MPG H.264 e huri ana i te kāwai): tata tonu ki te rahi ōrite. Ka taea te huri i te huringa pūkōrero: H.264 → H.265 i te nuinga o te wā e whakawātea ana i te pūkete i te āhuatanga ā-whakaahua ōrite; He āhua ōrite tonu te VP9; AV1 e whakaiti ana i tētahi atu 20-30% engari he pōturi ake te waehere.

MP4 / H.264 e tākaro ana i te āhua o te āhua o ia pūrere hōu. E tākaro ana te MOV / H.264 i ngā pūrere Apple me te nuinga o ngā TV, engari kāore i te wā katoa i runga i te Android tawhito. E hiahiatia ana e MKV te VLC i runga i te iOS. Ko te WebM te kaiwhaiwāhi tuatahi. Kei roto i ngā kōwhiringa hōu he "whakapae pūrere" e kōwhiri ana i te pūrere/kōrero MPG tino haumaru mō tō rātou whāinga. Ko MPG te whakaroanga o te pūmanawa tuhituhi DVD, e mōhiotia ana e ngā kāmera tawhito me ngā utauta whakateretanga pāohotanga, nā reira ka noho whai hua tonu mō ēnei pūtautau.

He tata tonu te whakarerekētanga o te pūkōrero ōrite — 30 ki te 60 sekona mō tētahi pūkōrero 1-ora. Ka haere te pūkōrero katoa ki te 0.3-0.7x te roanga pūtake i runga i tātau pūkōrero GPU, nō reira ka oti te 1-ora VOB → MPG i roto i te 18-40 minu e ai ki te rongoā me te pūkōrero ūnga.
