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 whakawhanake 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-pūmanawa, 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.

E whakawhirinaki ana ki te FLV kōpaka. MP4 te tīpako ki H.264 mō te tautoko pānui whānui rawa puta noa i ngā pūkoro, ngā kiritaki, me ngā Smart TV. MKV te tīpako ki H.265 / HEVC mō te haurua o te rahi o te pūkete i te āhuatanga ōrite. WebM te tīpako ki VP9. Ka whakawātea ngā kōwhiringa hōhonu i te kōwhiringa pūoko mēnā e hiahiatia ana kia whakawāteatia. 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 whakawaenga - ōrite te iti. Ki te rerekē ngā pūkōrero, ka whakawaengatia te oro ki te AAC / Opus / Vorbis i runga anō i te mea e tautoko ana te FLV kāwai. 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, i whakawāteatia te 29.97 → whakawhāiti 30, 60 rānei → 30 mō ngā tepe whakarewa), ka whakahaeretia e te kōwhiringa rārangi te 3:2 whakatata, te whakawāteatanga, me te whakakotahitanga rārangi i te whakawhitinga waehere ōrite.

He rite tonu te whakarerekētanga o te pūkōrero (WMV H.264 → FLV H.264 e huri ana i te kāwai): tata tonu ki te rahi ōrite. Ka taea te huri i te huringa pūkōrero: H.264 → H.265 i te nuinga o te wā e whakawātea ana i te pūkete 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 te āhua o te āhua o ia pūrere hōu. 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 kaiwhaiwāhi tuatahi. Kei roto i ngā kōwhiringa hōu he "whakapae pūrere" e kōwhiri ana i te pūrere/kōrero FLV tino haumaru mō tō rātou whāinga. 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 pūkōrero ōrite — 30 ki te 60 sekona mō tētahi pūkōrero 1-ora. Ka haere te pūkōrero katoa ki te 0.3-0.7x te roanga pūtake i runga i tātau pūkōrero GPU, nō reira ka oti te 1-ora WMV → FLV i roto i te 18-40 minu e ai ki te rongoā me te pūkōrero 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 te metadata HDR (HDR10, HDR10+, Dolby Vision ina noho) e mau ana i te wāhi e tautoko ana e ngā kāwai WMV me FLV.
