After being impressed with soundconverter, I decided to look for a front end for ffmpeg. What I found was WinFF, a multiplatform graphical interface to the video converter.

No more need to remember all the command-line option as WinFF already incorporates several presets. WinFF's layout is also quite intuitive, so there's not much to explain.

However, as I already covered before, the ffmpeg in the Ubuntu repositories does not incorporate some proprietary codecs. For this reason, it's best to compile and install your own. Then, specify the location of the files in WinFF's preferences.
