2Sankhani mmene zovuta kupweteka: quality kapena bitrate zofuna, ndi optionally ochepa kutalika ngati kukula ndi zofunika kwambiri kwa inu kuposa deta.
3Kuyamba ntchito ndi kulola ogwira ntchito re-kupaka wapamwamba; wanu oyambirira si nthawi zonse anasintha m'malo.
4Poyerekeza ndi kukula kwatsopano ndi mtundu wachibadwa, kenako ndikutsitsa fayilo ya GIF yosinthidwa.
Kuchepetsa GIF Mafunso Ofala
Kodi Kuchepetsa GIF imapanga fayilo yaying'ono?
+
Concretely, ntchito imakhala m'ma frame osati m'modzi: palette yogawana imasinthidwa, ma frame obwereza amatulutsidwa ndipo kugawa pakati pa ma frame kumasunga ma pixels omwe akuyenda, komwe kumachokera ku malo onse omwe amapulumutsa pa animation. Nothing about it depends on you installing software: the job runs server-side and hands back a finished file.
Kodi ndi ziti zosafunikira zomwe fayilo yanga idzalandira?
+
Zithunzi zazing'ono, zipatso za film ndi kulumikizana kwa sensor noise zimatsutsana ndi kulumikizana; mtundu woyera, malo akuluakulu, kulumikizana kwa line art ndi kulumikizana kwa mawu. Muyenera kuyembekezera kuchepetsa kwakukulu pazithunzi zazithunzi kapena logo ndi kuchepetsa kwachilendo pazithunzi zogwira ntchito.
Kodi mtundu wa fayilo yanga umasintha kuchuluka kwa ndalama zomwe ndingapulumutse?
+
Chotero kwambiri. GIF imathamanga pa 256-colour palette ndi single-bit (on/off) transparency ndi osachitapo kanthu alpha, chifukwa chake zithunzi zimayenda ndi kuwala m'malo mwake. Izi zimatsimikizira kuti pali ma headroom omwe alipo komanso ngati kupulumutsa kumakuwononga chilichonse m'chilungamo.
Kodi pali chinachake chokhacho cha GIF chomwe ndingadziwepo mukadzaza?
+
Yes — palette imagawidwa m'ma animations onse, choncho chilichonse chosintha kwa frame imodzi chimasankhidwa motsutsana ndi mabala omwe frame ina iliyonse ikufuna. Ndikofunika kudziwa kuti musanayambe kulemba pazomwe mungafunensonso.
Kodi ndi chiyani cholakwika chofala kwambiri pamene mukutsitsa GIF animations?
+
Kuzizira wapamwamba chimodzimodzi mobwerezabwereza. Kawirikawiri pa lossy mtundu ndi chitukuko chatsopano cha kuwonongeka ndi kupulumutsa kuchepetsa pamene kuwonongeka kumawonjezeka. Pitani kuchokera ku asalowe ku cholinga chanu m'njira imodzi, ndipo kusunga asalowe.
Kodi ndikufuna chiyani, ndipo ndingayang'ane bwanji kusiyana kwa ndalamazo?
+
Fayilo imodzi yozizira pa input, pa mlingo wabwino womwe mumasankha kuposa woyamba. Ngati zotsatirazo sizingatheke, kuchepetsa kukula kwa pixels kudzakhala kothandiza kuposa kuchepetsa mlingo wabwino.
Kodi ndingapeze chiyani pa Kuchepetsa GIF?
+
GIFs animated ndi static, kuphatikizapo WebP animated. Still zithunzi ntchitonso ndi kuonedwa ngati animation-frame imodzi, yomwe nthawi zina ndi zimene mukufuna pamene kulenga imodzi.
Kodi pali malire a kukula kwa fayilo pa Kuchepetsa GIF?
+
Yesani: maakaunti aulere amapanga zithunzi mpaka 25 MB, zomwe ndi zoletsa zachilendo za animation - maola angapo a GIF amtundu wa GIF amafika mofulumira.Ngati animation ili pamwamba pa malire, kuchepetsa kuchuluka kwa framerate ndi nthawi zonse kuyenera kukhala koyamba koyamba kuposa kuchepetsa kukula - khungu limalola 12 fps mofulumira kuposa momwe zimapangira chithunzi chocheperako.
Kodi Kuchepetsa GIF idzachepetsa mtundu wa GIF animations wanga?

Mphamvu yoletsa kugwirizana kwa GIF si ntchito, koma pali 256-color palette. Chomwecho chilichonse chomwe chimasintha ma pixels amachititsa kuti kugwirizana kwatsopano kukhalepo ndi palette yomwe imagawidwa ndi onse ma frame, komwe kumachokera ma bandings ndi dithering. Timing ya frame ndi kuwerengetsa kwa loop amasunga.
Yes, ndipo ndi zoyenera kuchita - per-fayilo overhead pa animation ndi wotchuka ndi decoding aliyense frame, kotero gulu amawawononga kwambiri bwino kuposa zofanana set of single maulendo.
Kodi animation amasunga, kapena ine kupeza chimango?
+
Animation ndi kupulumutsidwa. Gawo lililonse frame ndi decoded, processed ndi kusonkhanitsanso ndi zoyambirira delay ndi loop count intacts. Mudzakhalabe ngati inu mwamsanga kufunsa kwa modzi frame.
