How can I know the most proper values for video and audio bit rate within the output size I expect?
We have a small tool in the “Tools” menu, Bit Rate Calculator. By this tool, you will get the proper values for video and audio Bit Rate respectively according to the output size you enter there. Once again, you must highlight the title or chapter that you want to convert first. What you decide there will be shown in the relevant items on the right automatically after you confirm them.
