MP4 → 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 MP4 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. Ko MP4 anake e tautoko ana i tētahi hanga tuhituhi ā-whānui (mov_text), ā, kāore te oro-maha i te whakawhirinaki i waho o ngā kaiwhakaari papatahi.

Ko te nuinga mo te aronga. He MP4 he pūranga pāpāho taketake ISO, ā, ko taua whānau e tuhituhi ana i te hurihanga hei tohu i roto i te kāwai, kaua e te huri i ngā pikitia — ko te take ka taea e tētahi tākaro te kite tika i tētahi tākaro, ā, ka noho i tōna taha i tētahi atu. Ka hangaia te whakatangi mai i ngā pikitia whakawaenga, kia honoa ai taua tohu i mua i te tuhi i te tākaro tuatahi; mēnā ka hoki te tirohanga ki te taha, ka huri te pūtake me te tahuri anō. Ko ngā mea katoa e pā ana ki tētahi kāmera, tātuhi rānei ko te take ngāwari: tētahi whakataki ataata, tētahi aho pūmau o ngā tātai. Tata tonu ki ia MP4 i te mohoao he ataata H.264 me te oro AAC; kei roto hoki i te kāwai he HEVC, AV1 me VP9.

Ināianei, ina whai i te faila i a koe. Ko te MP4 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 MP4 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. Ko MP4 te ūnga whakawhiwhinga tino haumaru rawa - ko ia whatunga, kaitiaki, pāpāho, kaiwhakawhanake me te Smart TV i hangaia i roto i te tekau tau i muri mai e whakawhiwhia ana ki te kore pūmanawa tāpiri.

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 MP4 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 MP4 e kitea ana. Ka huri ki te WebP whakaata mō te pono-wairua.

He — ka whakamōkito te kōwhiringa rārangi ki raro i te MP4 i mua i te whakawāteatanga rārangi, e whakaiti ana i te rahi o te pūkete GIF. Ko te 480p GIF mai i te 4K MP4 e tata ana ki te 16x iti iho i te 4K GIF. Ka whakamahia te /video-cutter/ mō te whakaiti i tētahi hipanga motuhake.
