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 tātuhi 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 te whakawhiwhia, 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 mau ai te kōrero i te pūtoro matua, ā, ka tae mai ngā 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.

E ai ki te FLV. 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. 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.

Inā WMV me FLV 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 FLV. Ka tiakina te oro-maha (whakaaro, reo whirinoa).

Mā te pūmau, ā, — he 24fps WMV e noho ana i te 24fps i roto i FLV; he 60fps WMV 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 (WMV H.264 → FLV 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 FLV codec / waikawa tino haumaru mō tōtou ūnga. 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.

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 WMV → FLV 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 WMV me FLV.
