WebM → GIF

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 i roto i 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 tātari, engari ka taea anake te pai pēnei i te tau e tukua ana — tirohia i mua i te whakaatu i tētahi tākaro i mua i te whakapā atu 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 whāinga whāinga Matroska, ā, ka noho te whāinga me te pūkōrero i te wāhanga tino wehe - 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 pūkōrero i hangaia ai rātau. Kāore te utu whakakōrero i te ōrite: ko ngā pūkōrero hōu ake, he nui ake te roa o te whakawāteatanga i ngā tau o mua, nō reira e rua ngā WebM pūkōrero o te roa ōrite ka taea te roa kē atu i ngā wā rerekē hei tae ki te GIF ōrite. He whāiti te WebM: VP8, VP9 rānei te ataata (AV1 ināianei) me te Vorbis, te oro rānei, me ētahi atu.

Ināianei, ina whai i 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 whakarerekētanga he kaiwhakaari rerenga 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 ētahi atu mea e hiahiatia ana hei whakamātautau: kāore te kaha ki te whakataki i tētahi video i te ōrite ki te whakaae ki te tānga 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.

Kāore — he GIF he faila whakaahua, nō reira ka tīmata i te wā ka whakakōrerotia, ā, kāore e mau i te whakataetae, te whakawhāiti, te whakahaere rānei i tētahi wāhi. Ko te āhuatanga o te āhua, ehara i te pātaka e noho ana, ko te take e tino nui ai te tāruatanga tuatahi i tēnei i te wā i roto i tētahi ataata: ko ngā kaimātai i tono mo te nekeneke whakaiti, me ngā kaimātai tāuru e whakarārangi ana i tētahi tāruatanga anake, ka kitea taua tāruatanga, ā, kāore anō ētahi atu mea. Hiko tētahi pito tīmata e pānui ana te tāruatanga i te tāruatanga i runga i a ia anō.

He pai rawa te mahi a Animated GIF mō ngā tākaro i raro i te 10 sekona. I tua atu i tērā, ko ngā pūrere faila (ko te GIF te mea tino kāore i te whakawhāiti i te rārangi). Mō ngā whakatangi roa ake, ka ūngatia te WebP, APNG rānei, e rua e whakamahi ana i te whakawhāiti ā-wāhanga-kōrero-whitiāhua me te tauine pai ake.

GIF whakaata: 2 ki te 8 MB i te 480p e ai ki te matatinitanga o te nekeneke. WebP whakaata: 200 KB ki te 1 MB i te rongoā ōrite / āhuatanga. Ko te WebP whakaata 5 ki te 10 ngā wā nui ake i te GIF mō te āhuatanga ā-whakaahua ōrite. Kāore e ngaro te GIF engari i whakawhāititia ki te tae 256-wae i ia tā, mā te whakamahi i te whakawhāititanga LZW me te mārama ā-rua-wae kotahi.

Mā te pūmau ka whakamōhio mai mātou ki te 15 fps mō te GIF whakaata (e āhei ana ki te whakamātautau i runga ake i te 25 fps) me te 24 fps mō te WebP / APNG whakaata (e whakahaere ana i ngā mokatere tiketike ake). Whakapae mā te kōwhiringa whārite mēnā ka tautokona e tōmu kaitirotiro te mokatere pūtake.

Kāore — kāore ngā āhuahira GIF whakangākau (GIF, WebP, APNG) e rokiroki ai i te oro. Mēnā e hiahiatia ana e koe te oro, ka ūnga ki tētahi tahuri ataata (MP4, WebM) kaua ki tētahi āhuahira whakaahua whakangākau.

He — ko te kōwhiringa ripanga-tau e whakahaere ana mēnā he mutunga kore te GIF ripanga (whakahaere), ka tākaro N wā, ka tākaro rānei i te kotahi. Ka rokirokitia te tatau ripanga ki te GIF metadata kontener me te whakawhiwhia ki ia kaiwhakamatau hou.

E rua nga take noa iho. Tuatahi, ko te whakaiti i te rārangi-rārangi: 15 fps GIF mai i te 60 fps WebM e whakaiti ana i te 75% o ngā tāruatanga; ka whakaotitia me te tāruatanga rārangi-rārangi. Tuarua, ko te whakarārangitanga o te rārangi: Ka whakawhāititia te GIF ki te 256 ngā tae me te tauine-tōtō-tōtō WebM. Ka huri ki te WebP whakairo hei pono-whāiti.

He — ka whakamōhio te kōwhiringa whakarerekē i te WebM ki raro i te whakawāteatanga rārangi, e whakaiti ana i te rahi o te pūkete GIF. Ko te 480p GIF mai i te 4K WebM e tata ana ki te 16x iti iho i te 4K GIF. Ka whakamahia te /video-cutter/ mō te whakawhāiti i tētahi hipanga motuhake.
