MPG → MPEG

He, ā, ko te huarahi tere. MPG me MPEG 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-i-paepae, ā, ka tāruatia anō anake te whākōkī kāwai. Kāore he mea whakakōkī, ā, kāore he mea whakawhāiti anō, kia oti ai tētahi pūranga āhuahira-rohe i raro i te minu i te wā o te wā kotahi, ā, ko te huaputa o te huaputa e ōrite ana ki te pūtake. 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. Ko te tikanga o MPEG i tēnei he rerenga papatono MPEG-1, MPEG-2 rānei, ko te āhua i paerewa mō ngā CD Vitio, kātahi anō mō ngā DVD me ngā pouaka whakaata.

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. 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. E hiahiatia ana e MPEG-2 tata ki te whā ki te ono ngā wā o te mokatere bit o H.264 mō te whakaahua ōrite, ā, he rite tonu te whakawāteatanga o ōna ihirangi, e āhua ana he whakawātea i ngā whakaaturanga o nāianei.

E ai ki te MPEG. MP4 te pūnaha ki H.264 mō te tautoko pānui whānui rawa puta noa i ngā pūkoro, ngā kiriata, me ngā Smart TV. MKV te pūnaha ki H.265 / HEVC mō te haurua o te rahi o te faila i te āhuatanga ōrite. Ko te pūnaha WebM ki VP9. Ko ngā kōwhiringa tiketike e whakawātea ana i te kōwhiringa pūnaha mēnā e hiahiatia ana e koe kia whakawātea.

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

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

He rite tonu te kōwae-kore-kore (MPG H.264 → MPEG H.264 e huri ana i te kāwai): tata tonu ki te ōrite te rahi. Ka taea te huri i te kōwae: H.264 → H.265 i te nuinga o te wā e haurua ana te pūranga 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 ngā pūrere o nāianei. 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 kitenga tuatahi. Kei roto i ngā kōwhiringa tiketike he "whakapae pūrere" e kōwhiri ana i te MPEG codec / waikawa tino haumaru mō tōtou ūnga. Ka whakakōrerotia ngā rerenga papatono MPEG e ia kaiwhakaari DVD, te kāwai-tūtū me te mekameka whakapāpāho i hangaia i te wā katoa, ā, ka whakaaetia e rātau ngā hapa iti.

He tata tonu te whakarerekētanga o te pūrere ōrite — 30 ki te 60 ngā takiwā mō tētahi pūranga 1-ora. Ka haere te whakarerekētanga pūrere katoa i te 0.3-0.7x te roanga pūtake i runga i tātau pūtau GPU, nō reira ka oti te 1-ora MPG → MPEG i roto i ngā minu 18-40 i runga anō i te rongoā me te pūrere ūnga.

Tae atu ki te 8K (7680×4320) i runga i ngā mahere Premium. Ko ngā tahuritanga wātea e whakawhāititia ana ki te 4K (3840×2160) e te tepe o te rahi o te pūkete. Ko ngā metadata HDR (HDR10, HDR10+, Dolby Vision ina tīari) e mau ana i reira e tautoko ana e ngā kāwai MPG me MPEG.

He. Ka tuwhera ngā faila ataata i whakarewaina ki roto i ngā kaimahi motuhake, kāore i kitea e te tangata, kāore i whakarārangitia, ā, ka tangohia i roto i ngā minu o te whakaotitanga. Kua tuhituhitia te matapihi tauwhāiti i te /privacy/ ā, kāore e whakaputaina e tātau he whakaakoranga o te pūnaha mai i ngā tāurunga o te kaimahi.

Kāore i te hipanga ōrite — whakamahi i te /video-trim/, /video-cutter/ rānei hei whakaiti i te tuatahi, kātahi ka whakahaere i te tahuritanga MPG → MPEG. He tere ake te whakaiti me te tahuri i te whakakōrero anō i te katoa o te MPG kia kore ai e whakamahia te pūwhitinga.
