MPEG → MPG

He, ā, ko te huarahi tere. MPEG 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 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. 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.

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 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. 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.

He — ko ia whakataki oro i roto i te MPEG (whakaaro a te kaiwhakahaere, reo whirinoa, oro whakaahua) ka tiakina ki te MPG ina tautokona e te pūrere te oro-maha. MKV me MOV e whakahaere ana i ngā whakataki oro kāore i te whakawātea; he maha ngā MP4 e tautoko ana, engari ko ētahi kaiwhakaari pūrere e kite ana i te whakataki 1 anake; Ka whakawāteatia te WebM i te whakataki Opus / Vorbis kotahi.

Ka ora ngā whakahuatuhi māmā (ngā rererangi ka tīpakohia) ina taea e MPG te mau i a rātou: MKV kei roto i te SRT, ASS, SSA, PGS, VobSub māori; MP4 kei roto anake i te mov_text (he hanga whakawātea). Ko te tahuritanga o tētahi MKV me ngā whakahuatuhi āhua ASS ki MP4 ka whakaiti i a rātou ki te mov_text, ka whakarewa rānei i a rātou. Ko ngā whakahuatuhi matatini (i whakarewatia ki roto i te ataata) ka mau i a rātou ahakoa pēhea.

Ka whakawhitia ngā raraunga meta i waenganui i te MPEG me te MPG ina tautokona e ngā kāwai e rua tētahi ngota wāhanga (MKV, MP4, MOV). Ka penapena te WebM i ngā wāhanga i roto i tētahi kōpaka Matroska-hōpū, kia mārama ai ngā wāhanga MKV <-> WebM. Kāore he whakapūtā wāhanga a AVI, nā reira ka tahuri te tahuri AVI ki te MPG i tētahi pūranga kāore i te whakarārangi, engari rawa ka tāpiri i ngā tohu ā-ringa.

Ko MKV te mea anake e pupuri ana i ngā pūkete whakapiripiri (ngā tātuhi TTF mō ngā tātai ASS, ngā toi kāwai JPG, ngā tāurunga PDF i whakamāoritia). E haere ana mai i te MPEG ki te MPG ka whakapeka ēnei tātai ina kore te MPG he MKV — ka tahuri ngā rerenga taketake, engari ka noho te utu whakapiripiri i te pūtake. Whakataki MPEG hei tiaki i ētahi atu tātai mēnā e whakawhirinaki ana ki ngā tātai whakapiripiri.

E kōwhiritia ana te pūnaha waeheretanga pūnoa hei ōrite ki te MPG kaitakawaenga: MKV ngā pūnoa ki H.265 (HEVC) mō te whakawhāititanga pai ake; MP4 ngā pūnoa ki H.264 mō te tautoko pūrere whānui rawa; WebM ngā pūnoa ki VP9; AVI e whakamahi ana i te MPEG-4 ASP (DivX/Xvid lineage). Ka whakawātea mā te whakawātea codec hōhonu — Kei te wātea te AV1 mō MKV / WebM i reira e hiahiatia ana e koe te whakawhāititanga nui rawa, ā, ka taea te tūmanako mā te waehere. 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.

Ko te metadata HDR takoto (HDR10 nga uara whakaaturanga matua, te taumata mārama ihirangi) e mau ana ki te MPG ina tautokona e ngā kāwai me te pūāhua kōaro i kōwhiria (HEVC, AV1 i MKV / MP4). He nui ake te pōturi o Dolby Vision — ko te tātai DV 5 / 7 / 8.1 i te MPEG e ora noa ana ki te MKV me HEVC; te tahuri ki tētahi MPG kāwai kāore e mau ana i te apa DV ki te HDR10.

MKV me te WebM e whakataki ana i ngā rārangi wā-whāiti tūturu, ā, ka whakahaeretia e VFR māori, nā reira MPEG VFR e ora ana ki tētahi MPG o ēnei hanga kāore i te tāurunga. MP4 e pupuri ana hoki i ngā rārangi wā, engari ko ētahi kaitapere e whakaaro ana ki te CFR; Ka whakaaturia e te tahuri tētahi "pūngao CFR" e whakamātau ana i te VFR MPEG ki te 24 / 30 / 60 fps MPG mō ngā ūnga raruraru.

Ko te kōaro ōrite-kōrero remux e whakaputa ana i tētahi rahi tata tonu (he rerekē te taumaha o te kāwai e 0.1–2%). Ka taea e te huringa kōaro te huri i te rahi e 50%, neke atu rānei: H.264 ki H.265 e haurua ana i te faila i te āhuatanga ā-whakaahua ōrite; H.264 ki AV1 e haurua ana anō i runga i tētahi tauwhāiti pōturi. Ko te haere mai i tētahi bitrate tiketike MPEG (Blu-ray rip) ki tētahi bitrate iti MPG (whakahaere i te Wīwī) ko te take tino noa mō te hinganga nui.

He, tae atu ki te 8K (7680x4320) i runga i te Premium. Ka whakahaeretia e te taumata wātea 4K (3840x2160) tae atu ki te 1 GB te tauine faila. Ko ngā tāruatanga mārō (pānga-kōkiko ōrite) o te MPEG nui ki te MPG e whakawhāititia ana e te pūrere I/O, ehara i te CPU — ko te 30 GB MPEG e whakawhāiti ana ki te MPG i raro i te minu, ahakoa te rongoā. Ka whakawaenga anō me te tatau o ngā pikitia.
