Iisihloko ezisezantsi eziboshwe kwividiyo phambi kokuba ibe yi AV1 ziyingxaki eyahlukileyo - ngoko ziyinxalenye yomfanekiso kwaye yonke i-frame ekhutshwe igcina ezi.

Ingaba i-Image ixhasa ukubonakaliswa ngokucacileyo?

Ifomati isebenza, kodwa umbhali akafuni i-alpha ukunika - ii-frames zevidiyo kunye neephepha ezibonisiweyo zicacile ngokupheleleyo, ngoko ke zonke ii-pixels zifika ziqinile. Isiqhagamshelanisi se-alpha sihlala sisetyenziswa emva koko: kuthetha ukuba ungacima into ephuma kwi-Image kamva ngaphandle kokuguqula i-format kwakhona. Ukukhetha isiphelo ngokuzenzekelayo kuthetha ukuba ufumana ifayile evula naphi na ngaphandle kokufuna ukuqonda malunga nee codecs kuqala.

Oku kurhwebo oluchanekileyo xa imifanekiso i feed iqhubekeka, kwaye okubi xa zihamba ngqo kwiphepha le-web.

Lithini ubungakanani befayili yesakhelo esitshatweyo Image?

Ixhomekeke kwisisombululo kunye ne-Image codec. I-1080p PNG frame ihlala i-2 ukuya kwi-5 MB; i-1080p JPG kwi-quality-85 i-200 ukuya kwi-500 KB; i-4K PNG i-6 ukuya kwi-15 MB. Kwimeko egqithisileyo, ukukhupha i-PNG frame nganye ye-10-minute 1080p AV1 kwenza ~50 GB ngokupheleleyo.
