Yai, ndipo ndi chinthu chimodzi chofunikira kudziwa za mtundu. Kawirikawiri, kupulumutsa kumayendetsanso kuwonongeka kwa encoder pazithunzi zomwe zakhala zikuyenda, motero zigawo za artefacts - zomwe zimawoneka ngati zoletsa m'mawu ndi haloes pazovuta zazikulu pambuyo pa zaka zambiri. Sinthani kuchokera ku master yopanda kusowa ndi kutumiza ku HEIC kamodzi, pamapeto pake, kuposa kutsegulanso ndikubwezeretsanso fayilo yomweyo. HEIC imasunga zithunzi zosasintha zomwe zakonzedwa ndi HEVC - mtundu umenewo umagwiritsa ntchito ma codecs osiyanasiyana - ndipo imatha kunyamula zithunzi zambiri, mapu a kutalika ndi kusintha kopanda kuwononga m'fayilo imodzi.
Kodi ndiyenera kugwiritsa ntchito mtundu wotani posintha ku HEIC?

M'malo pakati pa 80 ndi 90 kwa chilichonse munthu adzaona. pansi pa 75 za artefacts ayamba kusonyeza pa khungu, kuwala ndi iliyonse lalikulu flat area; pamwamba 95 fayilo amakula mofulumira pamene pafupifupi palibe amene angaone kusiyana. kukhazikitsa si khalidwe la chithunzi, ndi lamulo la za izi padera kutumiza — choncho kusankha izo kwa kumene fayilo ndi kupita, ndi kusamalira oyambirira kwa nthawi ina inu mukufuna yankho lina.
Kodi nthawi ya frame ndi looping imatha kusinthidwa ndi HEIC?
+
Ku mtundu wina wothamanga, yeah — kulephera kwa frame ndi kuchuluka kwa loop amasungidwa mu fayilo ndipo amapita patsogolo. Ku mtundu wosasinthasintha, frame imodzi yokha imakhalapo, nthawi zambiri yoyamba. Ku kanema, loop flag siyiyenera kupita ku malo ena, chifukwa wosewerayo amasankha yekha ngati akufuna kubwereza. Kafukula galimoto ya kusewera pambuyo pake pamene frame rate imasintha: mitengo yokhazikika imatha kuyerekeza kulephera kwa frame.
Kodi HEIC ndi yatsopano kwambiri kuti ithandizidwe mokwanira?
+
Kuchepetsa choncho chaka chilichonse, koma kusiyana ndi lakuti. Software thandizo anafika mofulumira; hardware thandizo akubwera ndi zipangizo zatsopano, ndipo foni, TV kapena wosewera mpira m'mbuyomu inu angathe kungokhala preeminent izo. pamene ali ovomerezeka ndi kuyerekeza bwino kuposa mtundu amasintha, chifukwa chake ndi bwino kusintha kwa kutumiza ndi kusinthidwa kwa kugwirizana. HEIC imasunga zithunzi zokwana theka la kukula kwa JPG yofanana ndi mtundu wowoneka bwino, ndi 10-bit ya mtundu ndi chingwe cha alpha choyenera.
Kodi ndimafunikira Mac kuti ndichite ntchito ndi HEIC mafayilo?
+
No. The mtundu anatuluka Apple ndi zimene zake zipangizo ndi mapulogalamu kupanga mwa default, koma mavidiyo okha ndi osiyana ndi kuphunzira bwino kumeneko ndi choyenera chida. Kusinthanitsa pano chimachitika pa seva, kotero palibe QuickTime kukhazikitsa, palibe Apple hardware ndi palibe platform-osiyana codec pakiti ndi kukhudzana kulikonse m'njira.
Nchifukwa chiyani HEIC sichiwonekera mu browser yanga?
+
Popeza masamba asakatuli amagwiritsa ntchito mndandanda wafupi wazithunzi zazithunzi ndi HEIC ndi kunja kwa izo - zimakhudza kujambula, kusindikiza kapena kusintha ntchito yogwira ntchito kuposa pa web. Fayilo siyowonongeka; siyikhala ndi decoder patsamba. Kusintha kwa mtundu wazithunzi za web-native ndi njira imodzi yosinthira ndipo nthawi zambiri imapangitsa fayilo kukhala yocheperako. HEIC ndi patent-encumbered ndipobe akukana kwambiri: mabrowser sakusonyeza, Windows amafuna codec yowonjezera, ndi mafomu ambiri otsitsa amakana kuwonjezeka kwachidule.
Kodi ndingasinthe dzina la chidacho popeza HEIC sichisintha?
+
Kwambiri nthawi zonse, ndipo ndi bwino kumvetsa chifukwa chake: kuwonjezeka ndi label, pamene bytes m'maganizo ndi zopangidwa kwa mtundu wina mfundo. Kusintha dzina amapanga fayilo amene dzina lake amalonjeza chinachake za zinthu zake sikuti kubweretsa, ndi zimene amatsegula izo kapena amakana fayilo kapena misreads izo. Mmodzi waukulu kulephera ndi awiri mtundu amene ndi weniweni wofanana wonyamula pansi pa dzina losiyana - ndi ngakhale pamenepo bwino rewrap ndi chitetezo kuposa kusintha dzina.
