The chipangizo si chimapanga mfundo zazikulu, ndi kulemba zimene zake firmware akudziwa. Izi ndi chifukwa chakenso mavidiyo ndi lalikulu kwa zimene ali ndi chifukwa chake kusintha iwo ndi nthawi zambiri chinthu choyamba aliyense amachita.
Nchifukwa chiyani msakatuli wanga sadzasewera fayilo ya AVI?

Pa desktop yatsopano yomwe ndi yowononga; pafoni, laptop yakale kapena smart TV imawonekera ngati ma frame osunthira, mpweya wa fan ndi batri. Kusintha kwa mtundu wothandizidwa ndi hardware kumachotsa vuto lonse. AVI owona anayamba m'mbuyomo m'ma codecs m'madera: kuyembekezera MPEG-4 gawo 2 (DivX / Xvid), Motion JPEG kapena raw uncompressed mafano osati H.264.
Kupatulapo ngati zinthu zina zimafuna kuti zichotsedwe. 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?
