M4A → WebM

E kōwhiri ana e koe tēnei, nā te mea kāore he whakaahua i roto i te oro. Ko te pūmau he whakarārangi momo ngaru takoto, ā, ka taea e koe te whakarato i tētahi whakaahua tūturu i reira - te toi whakawhāiti, he kāri taitara, he whakaahua - e pupuritia ana mō te roanga katoa. Ko te mea e whakataki ana te faila ki ngā papatono whakaata anake kāore e whakaaetia ana he whakataki oro. Ka tākaro ā-iwi te WebM i ia kaitiaki o nāianei me te kore tāpiri, kāore he utu ātete, ā, kāore he whakaaturanga ā-patenta, e noho ana hei tīpāho mō te ataata whakawaitara-wārangi.

Ki te mea e whakaae ana te WebM kōwae ki te pūtake o te pūoko oro, ka tāruatia te rerenga i te kore e pā ki te āhua o te bit-identical. Ki te kore, ka whakakōrerotia te oro kotahi ki tētahi mea e whakaae ana te WebM, i te mokatere bit e ōrite ana ki te pūtake kia iti iho ai te utu o te whakawhitinga tuarua. Kei roto i te M4A te AAC i te nuinga o nga take, Apple Lossless rānei (ALAC) ina puta mai i tētahi tāruatanga kore. He whāiti te WebM: VP8, VP9 rānei te ataata (AV1 ināianei) me te Vorbis, te oro rānei, me ētahi atu.

He iti iho te nui ake, mēnā e whakamahia ana e koe te whakaahua tūturu pūmau. Ko te tāruatanga o tētahi tāruatanga kotahi ki te kore e tata ki te roa katoa nā te mea he ōrite ia tāruatanga ki te whakamutunga, nā reira ka whakahaeretia te faila e te rererangi oro. Mā te kōwhiri i tētahi āhua haurangi whakairoiro i te wāhi e tāpiri ai te raraunga ataata tūturu, ā, ka taea te rua, te toru rānei te hua.

Ko te nuinga o te wā. Ko te taitara me te kaiwaiata e mahere ana ki ngā āpure metadata o te pūrere ataata, ā, ko te toi kāwai i whakarārangitia he āhua tūturu mō te whakaahua tūturu e whakaatu ana te ataata. Ko ētahi atu mea katoa - te tau rererangi, te pūrākau, te tau, te momo - kāore he tauwāhi ōrite i roto i tētahi pūranga ataata, ā, ka whakawāteatia i te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te āhua o te

He — WebM e mau tika ana te oro-maha, nā reira ka noho te 5.1 he 5.1 me te papatono kanikani i te āhua nei, kaua e whakaroa ki te stereo. E pā ana tēnei mēnā kua whakaritea te faila mō tētahi kaiwhiwhi kiriata kāinga, kaua ko tētahi tātari, ka whakawātea i te wā whakataetae.

DRM, i te nuinga o ngā take. Kua whakawaeheretia tētahi M4A ā, ka hono ki tētahi kāwanatanga, ā, kāore e taea e tētahi kaiwhakarere te whakawaehere i a ia — tae atu ki a tātau. Ko ngā pūranga i hangaia e koe, i hokona rānei mai i tētahi whare DRM-free, ka whakawhiti i te kore raruraru. E rua nga mea rerekē e whakawāteatia ana e M4A i muri i tētahi whakaroanga — AAC ngaro me ALAC kore ngaro — ā, kāore te tautoko ā-Apple i te ōrite.

He — he wātea te tahuritanga taketake M4A -> WebM me te kore rāhuitanga. Ka tāpiri te utu ki ngā tepe nui ake o te tauine-reihi, he nui ake ngā kaimahi whakatōpū, ā, ka tangohia ngā whakatūnga.

Ko ngā kāwanatanga wātea: tae atu ki te 100 MB ia M4A. Whakawhiwhinga: i te nuinga o te 1 GB ia pūranga, i runga anō i te momo pūtake M4A. Ka wehea ngā pūranga nui ki ngā wāhanga pāpāho-pāpāho ina whakaaetia e te āhua WebM.

Ka pupuri te tahuri i ia wāhanga mōhiohio e taea ai e M4A me WebM te tohu. Kāore e taea te penapena i ngā āhuatanga o te āhua WebM (ngā raraunga raupapa i roto i te huaputa raster, ngā tātai i roto i te huaputa kupu-pūnoa, ngā tātai whakarārangi i roto i te huaputa whakaahua) ka whakarārangitia, ka whakawāteatia rānei - ko te hua o te pātū e tohu ana i ngā huaputa āhuahira.

He — he maha ngā pūkete M4A ki te rohe tāpiritanga, ā, he ōrite ōrite rātau. He nui ake ngā kaimahi ōrite o te Premium; i runga i te 50-file batch ko tēnei te rerekētanga i waenganui i ngā minu me ngā takirua.

Heoi — He urupare te UI, ā, ka haere te whakawhitinga i te taha hoapā, kia whakatakia ai ngā pūrere poke-kātahi ka whakatakia pēnei i ngā papamuri. iOS me ngā kaipāho Android (roller kāmera, taupānga Files) e mahi ana i te mutunga ki te mutunga me te kore taupānga.
