Sichipezeka mu njira yoyamba - kugwiritsa ntchito "1 pa mphindi" monga njira yowerengera, kenako kujambula zithunzi zosintha zithunzi. M'mabuku a maphunziro pali njira yopezera zithunzi zosintha zithunzi.

Kodi ndingagwiritse ntchito BMP ma frame omwe ndataya pantchito?

Ndiyo, malinga ndi lisensi yomwe imayendetsa WebM. Kusintha kwa mtundu sikungawonjezera chitsimikizo chilichonse - sitiwonjezera chizindikiro cha madzi ndipo sitigwiritsa ntchito lisensi pa BMP.
