Powerful Open Source Video Converter meGUI

Video converters are abundant, both paid and free ones, and developers tend to focus more towards simplicity, ease-of-use, etc to make it easier for an average Joe. meGUI is one of the most powerful open source feature-rich video converters out there, with less focus on simplicity and more towards performance. In a nutshell, it is targeted towards power users or the so called advanced users but that doesn’t make the app much difficult to use. If you have tried plenty of video converters before then using this app would be a piece-of-cake.

meGUI has a necessary dependency, an open source program called Avisynth, which should ideally be installed before installing meGUI. On its first run, the software will check for updates both for program components and encoding profiles.

The final step is to mux the audio and video. This is done by clicking on Tools > Muxer and selecting the appropriate tool (either avi, mkv or mp4) from the available options. Add the processed video and audio in the new window and queue the muxing in the end. Switch back to the queue tab and click the start button to begin muxing which will join the video and audio in the resulting video format. This completes the basics of a simple video conversion without involving all the parameters possible. There are automation options available as well but they need to be preconfigured. meGUI works great on Windows 7.
