This is the only program i use for video conversion now. Before I used to use Xillisoft, now I found this FF to produce a much better picture quality when converting to AVI using xvid engine with same bitrate on both programs. The user interface is not very flashy but if that is what is required for speed, I am happy with it. Once used to the interface, very smooth to operate and select what ever feature you like to use. It is ugly interface but the plus side is, you know where every functions are.
