WMV → FLV

Ka taea e ia te mahi engari rawa kāore i te whakawātea, ā, ko ngā ihirangi WMV 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 whakawhāiti te kaituhituhi i ngā āpure ki ngā tātai whakawhāiti katoa i mua i te tuhi i te FLV. Ko WMV te Windows Media Video, he hanga ā-ASF a Microsoft mai i te wā o Windows XP.

Tata tonu ki te DRM i ngā wā katoa. Ko ētahi WMV 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-whakahaere, ā, kāore e taea e te kaiwhakarere te whakaū i tētahi atu mea. He tino tūkino te WMV: e hiahiatia ana e macOS, iOS, Android me ia kaiwhaiwhai ngā whakakōrero tuatoru, ā, ko ētahi pūranga WMV e mau ana i te DRM kāore e taea te tahuri.

Ka whakawāteatia ki te pūoro, nā te mea kāore he ara ā-maha e whakawhirinaki ana ki te FLV. Ka whakamahia e te whakatata te taurite ITU paerewa kia noho ai te kōrero i te pūtoro matua, ā, ka tae mai te rohe ki te taumata iti iho, kaua e ngaro. He mea katoa e whakawhirinaki ana ki te tauwāhi pūtoro motuhake, kua ngaro i muri mai. Kāore he kaituhi, he pūkoro, he pouaka whakaata rānei e taea te whakatangi i te FLV - me neke atu ētahi mea i roto i tēnei kāwai kia noho ai te mātakina.

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.

He — ko ia whakataki oro i roto i te WMV (whakaaro a te kaiwhakahaere, reo whirinoa, oro whakaahua) ka tiakina ki te FLV 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. Ko te FLV te pūrere Video Flash nāna i mau te katoa o ngā ataata tīwae mai i te tau kotahi mano e 2003 tae noa ki te mutunga o te tau 2020.

Ka ora ngā whakahuatuhi māmā (ngā rererangi ka tīpakohia) ina taea e FLV 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 WMV me te FLV 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 FLV 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 WMV ki te FLV ka whakapeka ēnei tātai ina kore te FLV he MKV — ka tahuri ngā rerenga taketake, engari ka noho te utu whakapiripiri i te pūtake. Whakataki WMV 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 FLV 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 te utu iti o FLV i ia pakiaka i tino pai ai ki te whakawhitiwhiti i runga i ngā heretanga kāore i te tika o tōna wā, ā, kei te tīari tonu ngā pūranga nui.

Ko te metadata HDR takoto (HDR10 nga uara whakaaturanga matua, te taumata mārama ihirangi) e mau ana ki te FLV 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 WMV e ora noa ana ki te MKV me HEVC; te tahuri ki tētahi FLV 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 WMV VFR e ora ana ki tētahi FLV 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 WMV ki te 24 / 30 / 60 fps FLV mō ngā ūnga raruraru.
