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 o te whakaata GIF mō ngā tākaro i raro i te 10 sekone. I tua atu i tērā, ko ngā pūrere faila (ko te GIF te mea tino kāore i te whakawhāititia). Mō ngā whakaata roa ake, ka ūngatia te WebP whakaata, APNG rānei, e whakamahia ana e rāua te whakatakatanga ā-kōkiko-whakahaere-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 10x he nui ake te mātauranga 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 e whakaiti ana mātou ki te 15 fps mō te GIF whakaataata (e āhei ana ki te 25 fps) me te 24 fps mō te WebP / APNG whakaataata (e whakahaere ana i ngā mokatere tiketike ake). Whakapae mā te kōwhiringa whārite mēnā e tautoko ana e tōtou kaitirotiro i te mokatere pūtake.

Kāore — kāore ngā āhuahira GIF whakaata (GIF, WebP, APNG) e pupuri ana i te oro. Mēnā e hiahiatia ana e koe te oro, ka ūngatia tētahi taiwhanga ataata (MP4, WebM) i te wāhi o tētahi āhuahira whakaahua whakaata.

He — ko te kōwhiringa tatauranga porowhita e whakahaere ana mēnā he mutunga kore te GIF porowhita (whakahaere), e whakataetae ana i ngā wā N, e whakataetae ana rānei i tētahi. Ka rokirokitia te tatauranga porowhita ki te GIF metadata kontener, ā, ka whakaaetia e ia kaiwhakaata hou.

E rua nga take noa iho. Tuatahi, te whakaiti i te rārangi-rārangi: 15 fps GIF mai i te 60 fps WebM e whakaiti ana i te 75% o ngā tāurunga; ka whakaotitia me te tāurunga rārangi-rārangi. Tuarua, te whakarārangi rārangi: Ka whakawhāititia te GIF ki te 256 ngā tae me te tauine-maha WebM e kitea ana. Ka huri ki te WebP whakaata mō te pono-wairua.

He — ka whakamōkito te kōwhiringa rārangi ki raro i te WebM i mua 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 whakaiti i tētahi hipanga motuhake.
