This is the best flexible video converter ever. The only reason this software has such a low rating is because it also tries to act as a youtube downloader. However I think this is not the program for that and I think the developer should abandon this feature and only focus on the converter part. This software as a converter offers features like eg.: converting files from different folders and putting the converted file in the source folder, so far nothing special, but with the option when successful converted, to put the source file in the bin or any folder you want. Another feature is the flexibility and the possibility to write and save your own presets. Furthermore when you put in a file(s) eg. by drag-n-drop, it shows the size and duration, so you can easily judge if it is feasible to encode the file to save space or not. Well, just try it yourself as it opensource and free! Cheers
