Tahuri AV1 Tuhinga o mua WebM

Kāore i te āhua tika. AV1 e rokiroki ana i ngā aho maha hei whakataki ā-ira tuatahi, engari he āhua kore tonu te WebM tautoko whakataki i muri i te whakataki tuatahi, nā reira ko te nuinga o ngā kaiwhakaari ka whakaaturia anake tētahi. Ka kōwhiria te whakataki e hiahiatia ana e koe i mua i te tahuri; He pai ake te whakawātea i ētahi atu ki o rātau ake pūkete i te waiho i roto i tētahi kāwai e whakawātea ana i a rātau. E AV1 e whakarato ana i te whakawhāititanga tata ki te 30% pai ake i te H.264 i te āhuatanga ōrite, ā, kāore he utu ātete, nā reira e whakahaua ana e YouTube me Netflix. He kino te WebM i tētahi wāhi i waho o te kaiwhaiwāhi — ko ngā kaiwhakawhanake ataata, ngā whare karakia taketake o ngā tāuru me ngā Smart TV e tino whakakāhore ana i a ia.

Ka huri tēnei i te mea e tūmanakohia ana mai i te pūkete huaputa. Ko tētahi taha o tēnei tahuritanga e kiia ana he waehere, ehara i te whākōkī, nō reira ko te mea e hoki ana ko te rerenga ira i roto i te mea e tika ana — i te nuinga o te MP4, MKV rānei. Ko te whakaroanga e whakaatu ana i te mea; ko te pūkōrero te mea e whakatau ana i te rahi o te pūkete, ā, i reira ka whakapāpāhotia.

E ai ki te WebM. 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 WebM he huinga iti o Matroska i whakaputaina e Google i te tau 2010 hei whakarato i te pouaka whakaata HTML5 me te kore utu.

Inā AV1 me WebM 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 WebM. Ka tiakina te oro-maha (whakaaro, reo whirinoa).

Mā te pūmau, ā, — he 24fps AV1 e noho ana i te 24fps i roto i WebM; he 60fps AV1 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 (AV1 H.264 → WebM 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 WebM codec / waikawa tino haumaru mō tōtou ūnga. 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.

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 AV1 → WebM 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 AV1 me WebM.

He. Ka tuwhera ngā faila ataata i whakarewaina ki roto i ngā kaimahi motuhake, kāore i kitea e te tangata, kāore i whakarārangitia, ā, ka tangohia i roto i ngā minu o te whakaotitanga. Kua tuhituhitia te matapihi tauwhāiti i te /privacy/ ā, kāore e whakaputaina e tātau he whakaakoranga o te pūnaha mai i ngā tāurunga o te kaimahi.

Kāore i te hipanga ōrite — whakamahi i te /video-trim/, /video-cutter/ rānei hei whakaiti i te tuatahi, kātahi ka whakahaere i te tahuritanga AV1 → WebM. He tere ake te whakaiti me te tahuri i te whakakōrero anō i te katoa o te AV1 kia kore ai e whakamahia te pūwhitinga.
