Izi ndi chifukwa chakenso mavidiyo ndi zochepa kwa zimene ali ndi chifukwa chake kusintha iwo ndi nthawi zambiri chinthu choyamba aliyense amachita.

Formatiyo imangotsegulidwa, ndipo palibe vuto la kusintha archive yomwe siyikuyambitsa mavuto, koma sikuti ndi komweko kumene ma tool kapena efficiency akuyenda. Kwa chilichonse chokhudzana ndi zinthu zatsopano, formati yatsopano siyimawononga ndalama zowonjezera ndipo imateteza ku mafunso ena a m'tsogolomu zaka zingapo zapitazo.
Kodi ma subtitle amapita ku fayilo ya AVI?
