- I-AVIF inikeza ukucindezelwa okungcono ngaphezu kuka-50% kune-JPEG ngokusebenzisa i-AV1 video codec, okuthuthukisa kakhulu i-Core Web Vitals.
- Nakuba ukwesekwa kwesiphequluli manje sekucishe kube yinto yonke, isofthiwe yakudala kanye nezinsizakalo zokuphrinta zobungcweti zisadinga i-JPG ukuze ivumelane.
- Ukusebenzisa isu lokubuyela emuva kathathu ngesici sesithombe kuqinisekisa ulwazi lomsebenzisi olungenazihibe kuwo wonke amadivayisi.
Masibe yiqiniso: iwebhu empeleni iyiqoqo elikhulu lezithombe, futhi uma lezo zithombe zisinda kakhulu, abasebenzisi bakho bazogxuma ngokushesha kunalokho ongakusho “ububanzi bomkhawulokudonsa.” Sekuyisikhathi eside, besicabanga ukuthi i-WebP iyona mdlalo wokugcina, kodwa i-AVIF ingenelele ekubhaleni kabusha ngokuphelele incwadi yemithetho yokuthi siphatha kanjani izimpahla ezibonakalayo ku-inthanethi. Akuyona nje indlela encane yokulungisa; sikhuluma ngesinyathelo esikhulu ekusebenzeni kahle okwenza amafomethi esikole sakudala abukeke njengezinsalela zesikhathi sokudayela.
Uma wake wazibuza ukuthi kungani isiphequluli sakho se-Chrome siqala ngokuzumayo ukulondoloza izithombe njengamafayela e-.avif noma ukuthi kungani amanye amathuluzi akho ochwepheshe owathandayo engazivuli, usesendaweni efanele. Sizongena sijule ebuchosheni bobuchwepheshe be-AV1 codec , sihlole ukuthi singalinganisa kanjani ikhwalithi nosayizi wefayela, futhi sithole indlela engcono kakhulu yokukhonza lezi zithombe ukuze isayithi lakho lihlale lishesha ngaphandle kokuphazamisa abasebenzisi abasebenzisa imishini emidala.
I-Secret Sauce: Kungani i-AVIF ishintsha umdlalo
I-AVIF empeleni ayizange iqale njengefomethi yesithombe; empeleni iyifreyimu enganyakazi evela ku-codec yevidiyo ye-AV1 . Yasungulwa yi-Alliance for Open Media (kufaka phakathi iziqhwaga ezifana ne-Google, i-Netflix, ne-Amazon), yaklanywa ukubulala ama-codec anelayisensi futhi isinike indlela engenamali yokusakaza ividiyo ene-def ephezulu. Lapho besebenzisa lawo ma-algorithms afanayo ezithombeni ezimile, bathola okuthile okunamandla kakhulu: ikhono lokunciphisa osayizi bamafayela ngo-50% noma ngaphezulu uma kuqhathaniswa ne-JPEG ngenkathi kugcinwa ikhwalithi ebonakalayo ifana cishe.
Yini eyenza ibe ngcono kakhulu kune-WebP noma i-JPG? Konke kusezibalo. Ngenkathi i-JPEG isebenzisa uhlelo oluqinile lwamabhulokhi angu-8×8, i-AVIF isebenzisa ama-DCT transforms anosayizi oguquguqukayo , okusho ukuthi ingasebenzisa amabhulokhi amakhulu esibhakabhakeni esiluhlaza okwesibhakabhaka esicacile kanye namabhulokhi amancane ebusweni obunemininingwane. Ngaphezu kwalokho, isekela i- High Dynamic Range (HDR) kanye ne-Wide Color Gamut (WCG) , okuvumela imibala namazinga okukhanya angenakuba khona ku-JPG ejwayelekile.
Ukuwohloka Kobuchwepheshe: I-AV1 vs. Umhlaba
Ukuze singene shí embonweni, sidinga ukubheka izindlela ze-Intra Prediction . Ngenkathi i-WebP inezindlela ezimbalwa zokubikezela amaphikseli, i-AV1 inezindlela ezihlukene ezingu-71 zokuqondisa . Lokhu kuvumela i-encoder ukuthi inembe kakhulu ngalokho okwenzekayo esithombeni, okusho ukuthi kugcinwa idatha encane "engasasebenzi". Esinye isici esimangalisayo yi -Film Grain Synthesis . Esikhundleni sokuzama ukufaka ikhodi kuwo wonke umsindo esithombeni esikhanyayo kancane—esivame ukukhulisa usayizi wefayela—i-AVIF igcina nje amapharamitha ezibalo ze-grain bese itshela isiphequluli ukuthi "sizenzele" ngesikhathi sokudlala, silondoloze isikhala esiningi.
Ukushintshana: Isivinini vs. Ukusebenza Kahle
Nasi isiphetho: I-AVIF iyithuluzi eliwusizo kakhulu ngesikhathi sesigaba sokudala. Uma usebenzisa ithuluzi elifana ne -avifenc , uzobona ukuthi ukufaka ikhodi esithombeni kuthatha isikhathi eside kakhulu kunokuba bekungenzeka nge-WebP. Sikhuluma ngemizuzwana uma kuqhathaniswa nama-millisecond . Kwabathuthukisi abaningi, lokhu akuyona inkinga ngoba ukwenza kanye ngesikhathi senqubo yakho yokwakha, kodwa uma uzama ukuguqula izithombe ngokushesha kuseva ebukhoma , uzodinga isu lokulondoloza idatha elinamandla kakhulu noma uzoncibilikisa i-CPU yakho.
Ukuguqulwa Okusebenzayo: Kusukela ku-JPG kuya ku-AVIF
Uma usebenzisa isikhulu i-libavif amathuluzi, i cq-level (izinga lokulinganisa) yilona dial yakho ebaluleke kakhulu. Ngokungafani nesilinganiso se-JPEG esingu-0-100, Izinga le-cq le-AVIF liphambene: 0 ayilahleki (futhi inkulu kakhulu), kanti u-63 uyikhwalithi ephansi kakhulu. Kumaphrojekthi amaningi ewebhu, "Indawo emnandi" ivame ukuba phakathi kweminyaka eyi-18 nengama-23Noma yini ephansi ikunikeza izinzuzo ezinciphayo ngosayizi, futhi noma yini ephezulu iqala ukubukeka ilukhuni kancane uma usondeza isithombe.
Uma ukhululekile ngomugqa womyalo, ungakwenza lokhu ngokuzenzakalela usebenzisa iskripthi se-batch. Ukusetha ipharamitha ye-–speed ibe ngu-6 ngokuvamile kuyindlela engcono kakhulu yokulinganisela; kushesha ngokwanele ukuthi kungacasuli kodwa kusebenza kahle ngokwanele ukugcina lawo mafayela emancane. Kulabo abazonda i-terminal, amathuluzi asekelwe kuwebhu afana ne -Squoosh noma i-FormatVault akuvumela ukuthi ulungise ikhwalithi ngokubonakalayo futhi ubone imiphumela ngesikhathi sangempela ngaphandle kokufaka into.
Igebe Lokuhambisana: Kungani Usadinga I-JPG
Naphezu kokuba nokusekelwa kwesiphequluli okucishe kube ngu-95% ku-Chrome, Firefox, Safari, kanye ne-Edge, i-AVIF akuyona into ewusizo kukho konke. Inkinga akuyona isiphequluli; konke okunye. Isofthiwe endala efana ne-Photoshop CS6 , izinguqulo ezindala ze-Windows Photo Viewer, kanye nama-portal amaningi kahulumeni noma ezinkampani awakwazi ukufunda amafayela e-AVIF. Uma uzama ukulayisha i-.avif kusevisi yokuphrinta noma i-CMS endala, cishe izovele ifake iphutha lokuqinisekisa.
Yingakho ukuguqula i-AVIF ibe yi-JPG kuseyikhono elidingekayo. Kungakhathaliseki ukuthi kungokweklayenti le-imeyili elifana ne-Outlook elingakwenzi lokho, noma isethulo se-PowerPoint, i-JPG isalokhu iwulimi olujwayelekile lwezithombe. Amathuluzi afana ne -Total Image Converter alungele lokhu, ikakhulukazi uma udinga ukucubungula ifolda yonke yokulandwa ngesikhathi esisodwa.
Ukukhonza Izithombe Njengochwepheshe: I-Triple Fallback
Akufanele nje ushintshe ama-JPG akho ngama-AVIF bese uthemba ukuthi kuzokwenzeka okuhle. Indlela yobungcweti yokwenza lokhu ukusebenzisa <picture> isici. Ngokufaka ohlwini I-AVIF kuqala, bese kuba yi-WebP, bese kuba yi-JPEG ekugcineni, uvumela isiphequluli ukuthi sikhethe ifomethi engcono kakhulu esiyiqondayo ngempela. Kufana nokuba nemenyu enezinketho ezintathu; isiphequluli sithatha eyokuqala esiyithandayo.
Ukugcina i- Amavidiyo we-Core Web kuluhlaza okotshani, faka njalo izimfanelo zobubanzi nokuphakama ezicacileLokhu kuvimbela i-Cumulative Layout Shift (CLS) eyesabekayo, lapho okuqukethwe kwakho kugxumagxuma khona ngenkathi izithombe zilayisha. Ukuze uthole isithombe sakho "seqhawe" esiyinhloko, engeza fetchpriority="high" ukutshela isiphequluli ukuthi sibambe ngokushesha, kodwa sebenzisa loading="lazy" ukuze konke okunye kugcine umthwalo wokuqala ulula.
Umthelela ku-SEO kanye nolwazi lomsebenzisi
I-Google ayikuniki ibheji ngokusebenzisa i-AVIF kuphela, kodwa igxila kakhulu ku-LCP (Largest Contentful Paint) . Uma unciphisa isithombe esikhulu somkhiqizo kusuka ku-400KB siye ku-150KB, unciphisa ngqo isikhathi esisithathayo ukuze ikhasi lizizwe "likulungele." Lokhu kuholela emazingeni aphansi okushintshashintsha kanye nokuguqulwa okuphezulu , ikakhulukazi kubasebenzisi abaxhumene neselula lapho i-kilobyte ngayinye ibalwa khona.
