Q1: How to improve the quality of converted files?

A: Generally speaking, the output quality can be improved by modifying "Video Size" and video "Bit Rate". After you highlight the loaded file into the program, you will be able to modify them on the right panel of the main interface. But in certain format, there would be some limitations. And also, the output files would be in a larger size if you set larger values for these two items.
