From the "Choose Quality" button, set between Best, Normal, or Custom quality. Choosing quality will be the default from now on. Best Quality It is the ideal format for all sorts of content and downloads speed. Normal Quality All downloads will be of Normal Quality. It's lower than the Best quality but with little difference. But it'll increase the download speed. Custom Quality Please select from available qualities, and it could be normal or best. Every time system will ask you to choose quality.
