Ngabe isithombe esikhishwayo PNG siphuma ngesinqumo esingakanani?

Ukulungiswa okufanayo njenge WebM ividiyo — umsuka we-1080p ukhiqiza amafreyimu we-1920×1080 PNG; umsuka we-4K ukhiqiza amafreyimu we-3840×2160 PNG. Buyisela ubukhulu ngemuva kokukhishwa uma ufuna amathumbnail amancane.

Kungani ama-PNG amafreyimu ami akhishwa amnyama?

Kuyinto evamile ukushaya umsindo ovela emthonjeni WebM (ikhamera ihamba lapho ifreyimu ithathwa). Zama ukukhetha ama-timestamps kusuka emibonweni ehlala njalo, noma khipha amafreyimu ambalwa azungeze futhi ukhethe oqinile. Ipayipi alikhiqizi uqinile.

Ingabe le thuluzi lixhasa ukukhishwa kwefremu eyodwa ngeshintsho lendawo yokubukeka?

Akuna. Umguquli awunakukhomba isiboniso futhi awunakho indlela yesikhathi esisodwa-ngesekunxele: igcina noma ifremu eyodwa ngesikhathi esilandelayo lapho ufaka khona noma ifremu ngayinye. Isithombe esisodwa sesithombe, khipha ifremu eyodwa ngesikhathi isiboniso sishintsha.
