Most video formats have a quality setting bar and some of them have Online/Offline option. Online and Offline options refers to that the source is a living source (online) or just a video file at local machine or network (offline). Choose a mode wisely according to the source in use.
- If it’s online, the bar refers to a performance bar. As it is increased, application works with better performance but may sacrifice quality.
-If offline is chosen, this bar refers to quality this time since performance is not that important according to online sources. As quality bar increases, quality of encoding gets increase but may cause encoder to slow due to machine’s system.
