[Top AVI Converter] 1. Free Studio [Pros] A good-looking interface, it lets you control the output properties of your video and it offers a very good performance. [Cons] As you are working you will notice certain windows showing up every one in a while that will annoy you here and there and it only has support for Windows users. [Key Features] 
This application offers a wide range of multimedia options, on a good interface as well and lets you control most of the option you need on your files, but most of the software included in it are tools that you probably will not use that much. The problem with this application, among others is that you get a pop-up with advertisement every once in a while. Guess nothing comes completely free.
