Uma idivayisi yakho yeselula, isithombe noma ikhamera yevidiyo ikwazi ukurekhoda futhi ithwebule izithombe ngefomethi ye-HEIF noma ye-HEVC, kufanele usebenzise ngokunenzuzo. Ngoba ngendlela efanayo i-iPhone ejabulela ngayo isikhala esingenamkhawulo futhi ngaphandle kokulahlekelwa ikhwalithi kokuthi Izithombe ze-Google, okuthile kuze kube manje okwakuyinzuzo ye-Google Pixel kuphela, idivayisi yakho nayo ingaba nayo. Ngoba? Hhayi-ke, qhubeka ufunda futhi sizokutshela konke mayelana namafayela we-HEIF ne-HEVC, izinzuzo zayo kanye nebubi (okukhona futhi).
Amafomethi wesithombe se-HEIF ne-HEVC
Kuze kube manje, i-codec ye-H.264 kanye namafayela e-JPEG bekulokhu futhi kuseyizinketho ezidume kakhulu lapho ukhiqiza ividiyo noma ifayela lesithombe. Ziyisixazululo esihle futhi izinga lokuhambisana kwazo lisho ukuthi azikho izinkinga lapho uzibuka kunoma iyiphi isistimu yokusebenza kanye nedivayisi. Inkinga ukuthi azikho ezingeni eliphezulu njengoba kudingeka namuhla iminyaka.
Ngalesi sizathu, futhi ngaphandle kokuba ifomethi ye-RAW isisombululo sangempela somsebenzisi ojwayelekile ngenxa yalokho akuthathayo, kwafunwa isixazululo esikwazi ukuthuthukisa zonke lezi zici ezihlobene nekhwalithi nosayizi wefayela. Lena yindlela amafomethi we-HEIF kanye ne-HEVC avela ngayo. I-Apple yayingenye yezinkampani zokuqala ukuyisekela nge-iOS 11 kanye ne-macOS High Sierra. Nokho, lena akuyona ifomethi yobunikazi, ngakho-ke noma yimuphi omunye umkhiqizi nohlelo lokusebenza angahlanganisa ukwesekwa.
Endabeni yeWindows, bekukade kukhona, kepha manje yengezwa ngesandiso esilula esikuvumela ukuthi udlale ividiyo ye-HEVC kunoma yimuphi umdlali. Yebo kunjalo, intengo yesandiso yi-0,99 euros, nakuba inani lincane ngezinzuzo onazo ngokusekelwa okushiwo. Ngokuya ngamadivayisi eselula, i-Android 10 izokwengeza ukwesekwa ngokwemvelo, abakhiqizi abaningi bazohlomula kuyo. Kunjalo, akhona kakade amabhrendi avumela ukugcinwa ngefomethi ye-HEIF naphezu kokuba kunguqulo ephansi ye-Android.
Mayelana ne-HEIF ne-HEVC, awawona amafomethi ngokwawo kodwa ayiziqukathi. Okusho ukuthi, kuyilapho ku-JPEG kugcinwa isithombe esisodwa kuphela, ku-HEIF ukulandelana okuphelele kungagcinwa ngaphezu kwedatha eminingi ehlobene. Lokhu, ngokubuka imisebenzi emisha njengokuthwebula amavidiyo amafushane ngaphambi kokuthatha isithombe, kuyathakazelisa. Nakuba into engcono kakhulu ukuthi ikhwalithi ayilahleki futhi ubukhulu bokugcina bulawuleka kakhulu.
Amafayela e-HEIF nawe-HEVC ngokuvamile athatha cishe uhhafu kune-JPEG yayo efanayo noma ifayela levidiyo elingasetshenziswa. Ngenxa yalokhu nokuthi idatha yesithombe ngasinye icutshungulwa kanjani, ungakwazi ukujabulela ikhwalithi eyengeziwe ngaphandle kokudinga isikhala esengeziwe. Futhi-ke, ngaphandle kwamayunithi okugcina amakhulu ngokwedlulele okwamanje -abakhiqizi abaningi basabambelele kusisekelo esingu-64 GB naphezu kwamanani entengo yamatheminali abo, ahem ahem Apple- namakhamera akwazi ukuqopha ngokulungiswa kwe-4K, nabaningana kubo ngasikhathi sinye. , Izithombe Ezibukhoma, njll., zonke lezi zibalulekile.
Ngokufanayo, uma lezi kuyizinzuzo zawo womabili amafomethi, futhi kubalulekile ukwazi ukonakala kwayo. Okokuqala nokubaluleke kakhulu ukuthi kudinga ihadiwe enamandla kakhulu ukuze udale futhi uphathe. Emishinini yamanje akuyona inkinga ngoba banamayunithi athile ale misebenzi. Uma kungenjalo, inqubo kufanele yenziwe ngesofthiwe, kulayishwa i-CPU yekhompyutha ngaphezulu.
Ukunciphisa lowo mthwalo lapho wabelana ngokuqukethwe, ezinye izinhlelo ziguqulela ku-H.264 noma i-JPEG ukuze kube lula ukuphatha kukhompuyutha okuyiwa kuyo. Inkinga ukuthi izinzuzo zokuqala zilahlekile. Uyazi, ukusekelwa kolwazi olwengeziwe, izithombe zesikhala sombala we-16-bit ngokumelene nesikhala sombala esingu-8-bit se-jpeg, ukugcinwa kwenguqulo, isilinganiso esingcono sokuminyanisa esingu-40%, njll.
Ngakho-ke, noma nini lapho ukwazi, sebenzisa lezi zakhiwo ezintsha. Ikakhulukazi kusuka kumadivayisi eselula. Ngoba, njengoba sishilo, endabeni ye-Google Photos, uma ifayela line- ukulungiswa okungaphansi kuka-16MP futhi usebenzise ifomethi ye-HEIF uzokwazi ukujabulela inketho yesikhala esingenamkhawulo nekhwalithi yoqobo ngaphandle kokukhokha okunye. Ngoba uma i-Google iguqulele ku-JPEG, ngokwesibonelo, ifayela lizothatha okungaphezu kwelangempela.
