Imibuzo ebuzwa qho

Nguwuphi umahluko phakathi kokudluliselwa kweekhowudi kunye nokuguqula iifayile zevidiyo?

Ngelixa esetyenziswa rhoqo ngokutshintshanayo, la magama anomahluko ofihlakeleyo kodwa obalulekileyo kwiimeko zobuchwephesha. Ukuguqulwa kwevidiyo ngokubanzi ibhekisa ekutshintsheni ividiyo ukusuka kwifomati enye ukuya kwenye, enokubandakanya ukutshintsha isikhongozeli (umzekelo, MOV ukuya kwiMP4), icodec, isisombululo, okanye ezinye iiparamitha. Ligama elibanzi eliquka iintlobo ngeentlobo zeenguqu.

Ukuguqula iikhowudi, ngakumbi, ibhekisa ekuguquleni ikhowudi kwividiyo kwikhowudi enye kwaye uyifake kwakhona kwenye ikhowudi. Olu luhlobo loguqulo olujolise ngokukodwa kwinkqubo yokufakwa kweekhowudi kunokutshintsha nje izikhongozeli okanye imetadata. Umzekelo, ukuguqula i-H.264 ukuya kwi-H.265/HEVC iya kuba yi-transcoding.
