VOB → WebM

Ka taea e ia te mahi engari rawa kāore i te whakawātea, ā, ko ngā ihirangi VOB he tino whakawātea nā te mea ka tae mai te āhua i te wā o te whakawāteatanga me te DVD. Ka rokiroki ngā tātuhi whakawātea i ngā āpure haurua-whakapaetata e rua i whakawāteatia i te rima tekau o te tuarua; i runga i tētahi tātari pūwhitiwhiti, mātakitaki rānei e ako ana hei whakawhāiti whakawhāiti i tētahi mea e neke ana. Ka whakahohe te kōwhiringa whakawhāiti, ā, ka whakawhanake te kaituhituhi i ngā āpure ki ngā tātuhi whakawhāiti katoa i mua i te tuhi i te WebM. 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.

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. WebM 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 i te āhua tika. VOB e rokiroki ana i ngā aho maha hei whakataki ā-ira tuatahi, engari he āhua kore tonu te WebM tautoko whakataki i muri i te whakataki tuatahi, nā reira ko te nuinga o ngā kaiwhakaari ka whakaaturia anake tētahi. Ka kōwhiria te whakataki e hiahiatia ana e koe i mua i te tahuri; He pai ake te whakawātea i ētahi atu ki o rātau ake pūkete i te waiho i roto i tētahi kāwai e whakawātea ana i a rātau. Ka tiaki e te VOB te nui katoa o te DVD - he maha nga aronga, he maha nga reo oro me ngā aho whakahuatuhi e ora ana i roto. He kino te WebM i tētahi wāhi i waho o te kaiwhaiwāhi — ko ngā kaiwhakawhanake ataata, ngā whare karakia taketake o ngā tāuru me ngā Smart TV e tino whakakāhore ana i a ia.

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.

Heoi, ā, ko te tikanga ko te take katoa mō te tahuritanga. Ko tētahi VOB i whakawāteatia i roto i tētahi pātaka whatunga, e whakaatu ana i tētahi kaiwhakaari whakarewa, he whakahau rānei i tētahi whakataki, nā te mea kāore he whakawātea mō te whakawāteatanga. WebM e whakawāteatia ana i roto i te huānga o te HTML5 māori me te kore tātai, me te kore taupānga o waho. Ka tākaro ā-iwi te WebM i ia kaitiaki o nāianei me te kore tāpiri, kāore he utu ātete, ā, kāore he whakaaturanga ā-patenta, e noho ana hei tīpāho mō te ataata whakawaitara-wārangi.

Mō ētahi mea e hiahia ana koe ki te pupuri, ā, kei te VOB tētahi whakatupuranga o mua o ngā utauta ataata, ā, ko te pūmanawa e ako ana i a ia e ngaro tonu ana i ngā pūrongo, ngā kiritaki me ngā pūnaha whakahaere. Ko te neke i te pūwhitinga ki WebM ināianei, ahakoa kei te tīariari tonu tētahi whakakōrero mārō, ko te rerekētanga i waenganui i tētahi pūranga ka taea e koe te whakatupuranga tekau tau me tētahi kāore e taea e koe.

E whakawhirinaki ana ki te WebM 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. Ko te WebM he huinga iti o Matroska i whakaputaina e Google i te tau 2010 hei whakarato i te pouaka whakaata HTML5 me te kore utu.

Inā VOB me WebM 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 WebM 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 WebM; 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 → WebM 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 WebM tino haumaru mō tō rātou whāinga.
