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-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 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.

He — ko ia whakataki oro i roto i te MPG (whakaaro a te kaiwhakahaere, reo whirinoa, oro whakaahua) ka tiakina ki te MPEG 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 MPEG 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 MPG me te MPEG 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 MPEG 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 MPG ki te MPEG ka whakapeka ēnei tātai ina kore te MPEG he MKV — ka tahuri ngā rerenga taketake, engari ka noho te utu whakapiripiri i te pūtake. Whakataki MPG 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 MPEG 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. 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.

Ko te metadata HDR takoto (HDR10 nga uara whakaaturanga matua, te taumata mārama ihirangi) e mau ana ki te MPEG 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 MPG e ora noa ana ki te MKV me HEVC; te tahuri ki tētahi MPEG 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 MPG VFR e ora ana ki tētahi MPEG 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 MPG ki te 24 / 30 / 60 fps MPEG 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 MPG (Blu-ray rip) ki tētahi bitrate iti MPEG (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 MPG nui ki te MPEG e whakawhāititia ana e te pūrere I/O, ehara i te CPU — ko te 30 GB MPG e whakawhāiti ana ki te MPEG i raro i te minu, ahakoa te rongoā. Ka whakawaenga anō me te tatau o ngā pikitia.
