WebM → WebP

Ka whakatuwheratia ki roto i tētahi kaiwhakaari, ki te kimi i te wā me te tuhituhi i te wa, nā te mea kāore he WebM e mau ana i ngā tohu wāhanga hei whakatere i te nuinga o te wā. Ka whakatū i taua mea ki te āpure wā tīmatanga, ka tāpiri i tētahi roanga, ā, ka rapu te kaiwhakarere ki taua wāhi, ā, ka whakawātea anake i te tauine i tonoa e koe. He tika te rapu ki te tāwhana, engari ka pai rawa te tau e tukua ana — tirohia i mua i te whakaatu i te whakataki ki tētahi tātari roa. 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.

Ehara i te pikitia, ko te tūmanako anake. He WebM tētahi wharekaringa whānau Matroska, ā, ka noho te whānau i te wharekaringa me te pūrere whakawātea katoa - i whakatauria te mea i pupuri ai te faila i te wā i tuhituhitia, ā, kāore i whakawāteatia e te whakaroanga. Ka whakakōrerotia e te kaiwhakarere ngā mea e kitea ana ki ngā tāruatanga mārō i te tuatahi, ā, he ōrite ēnei tāruatanga ki te pūrere whakawhāiti i hangaia ai rātau. Kāore te utu whakakōrero i te ōrite: ko ngā pūrere hōu ake, he nui ake te roa o te whakawāteatanga i ngā mea tawhito, nō reira e rua ngā WebM pūkete o te roanga ōrite ka taea te roa kē atu i ngā wā rerekē hei tae ki te WebP ōrite. He whāiti te WebM: VP8, VP9 rānei te ataata (AV1 ināianei) me te Vorbis, te oro rānei, me ētahi atu.

He, ina whai te faila i a koe. Ko te WebM te mea e whakamahia ana e te Wīwī mō te ataata i roto i te raina, nā te mea kāore e whakapāpāhotia e ngā kaitiaki i te tā, nā reira ko te tākaro e whakapāhotia ana i roto i tētahi tīpako he WebM noa iho e tiaki ana, e whakarewa ana i reira pēnei i ētahi atu rārangi. Ko te āhua o te pūpāho tāuru e tuku ana i ngā wāhanga tau poto i te wāhi kotahi - me whakakotahi anō i mua i te whakarerekētanga o tētahi mea. Ko ngā mana ko tētahi atu mea e hiahiatia ana hei whakamātautau: kāore te kaha ki te whakataki i tētahi video i te ōrite ki te whakaae ki te whakaputa anō i tētahi whakaahuatanga i hangaia mai i a ia. 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.

Ko te ngaro, mō tētahi mea i tīmata hei ataata. Ka taea e tētahi whakaata WebP te whakawaehere i ōna tātuhi i te tikanga: ka pupuri te āhuatanga kore ngaro i ia piko, ā, ka ōrite ki ngā whakaahua papatahi me te kupu whakaata, i te wā e whakamahi ana te āhuatanga ngaro i te matapae ā-pātū o te momo e whakamahia ana e te pūkōrero ataata, ā, ka ōrite ki te pūwhitinga tūturu. He tino mārō ngā tātuhi kāmera me ngā kāwai e kitea ana e te whakawhāiti kore ngaro he tauira, nō reira ka taea e te whakaata kore ngaro o tētahi tātuhi whakatata te neke i ngā wā maha o te rahi o tētahi āhua ōrite. Ka waiho i te ngaro, engari rawa i te pūtake he whakataki mata o te kupu whakaata. Kei te WebP tonu te waeine tuarua i waho o te kaiwhaiwāhi — kāore e whakaaetia e ngā rerenga mahi tātai, ngā hanganga Tari tahito me ētahi whare tātari.

Ko te Animated WebP he rahi mō ngā tākaro i raro i te 10 sekone. He roa ake i tērā, ā, ka tere te tere o te huaputa — kāore te GIF i te whakawhāiti-i-te-whāiti, nō reira ko ngā tākaro māmā tonu e haere ana ki ngā megabytes maha. Mō ngā tākaro roa ake, ka ūngatia te WebP whakaata, APNG rānei, e ōrite ana ki ngā pūrere ā-whitiāhua o nāianei.

Mō te GIF whakaata i te 480p ko te hua noa iho ko te 2-8 MB e ai ki te matatinitanga o te nekeneke. Mō te WebP whakaata i te rongoā/whakahaere ōrite, e tūmanako ana ki te 200 KB ki te 1 MB — he 5-10 ngā wā nui ake te WebP whakaata i te GIF mō te āhuatanga ā-whakahaere ōrite. Ka whakarato rā anō te WebP i ngā āhuatanga ngaro me te kore ngaro, me te mārama ā-arawhiti me te whakaata i te taha kotahi.

Mā te pūmau e whakaiti ana mātou ki te 15 fps mō te GIF whakaata (ka pōturi te mahi a GIF i runga ake i te 25 fps i roto i te nuinga o ngā kaitirotiro) me te 24 fps mō te WebP / APNG whakaata (e whakahaere ana i ngā mokatere tiketike ake). Ka whakahōutia e te kōwhiringa whārite te pūmau hei pupuri i te mokatere pūtake mai i tōtou WebM mēnā ka tautokona e tōtou kaitirotiro ūnga.

Kāore — kāore ngā āhuatanga WebP whakaataata (GIF, WebP, APNG) e rokiroki ana i te oro. Mēnā e hiahiatia ana e koe te oro me tō koe tākaro, ka ūngatia tētahi tapawhā ataata (MP4, WebM, MKV) i te wāhi o WebP. He maha ngā whakataki pāpori (Twitter, Discord) e tahuri ana i ngā tāpiritanga MP4 ki ngā porowhita whakaari-whakaari-GIF, e tuku ana i te pai rawa o ngā mea e rua.

He — ko te kōwhiringa tatauranga-tau e whakahaere ana mēnā ka whakaroa te WebP i te mutunga kore (whakahaere), ka whakataetae N ngā wā, ka whakataetae rānei kotahi me te tū. Ka rokirokitia te tatauranga loop ki te WebP metadata kontener, ā, ka whakaaetia e ia kaiwhakaata hou, kaiwhakaari whetū, me te mata whakataki.

E rua nga take noa iho: te whakaiti i te rārangi-rārangi (e tango ana tātau i tētahi 30 fps GIF WebM ki te 15 fps mā te pūnaha — ka whakaiti te kōwhiringa rārangi ki te whakaora) me te whakarārangi rārangi (e whakawhāiti ana te GIF ki te 256 tae ia rārangi, e whakarārangi ana i ngā taumata i roto i tētahi āhuatanga kāore i mahi ai te taketake WebM). Ka huri te ūnga ki te WebP whakaataata mō te pono tae katoa.

He — ka whakamōkito te kōwhiringa whakarea i te tāuru i mua i te whakawāteatanga rārangi, e whakaiti ana i te rahi whakamutunga. He 480p i hangaia mai i tētahi 4K WebM he 16x iti iho i runga i te pūrere i tētahi 4K WebP. Ka whakahaeretia te whakaroa i roto i tētahi /trim/ motuhake, i tētahi /crop/ rānei i mua i te tahuri.
