ffmpegX is an application that allows users to convert between a very generous range of audio and video extensions. It makes use of some of the most popular open-source media processing tools available (well-known for their flexibility and speed like ffmpeg, mpeg2enc and mencoder) to offer a fully customizable conversion alternative.
Thanks to the 20 Unix tools integrated, the capabilities of ffmpegX are certainly impressive. You can choose a specific audio or video codec used for encoding, change the bitrate, sampling, channels and many more parameters in order to reach the desired output.
The application also provides multiple presets for quick conversion tasks as well as drag and drop support. While both features are meant to enhance your productivity, ffmpegX has no support for batch conversion; users can only convert one file at a time.
With this tool you can add subtitles to your video files after converting them to a new format. This is available to the popular VobSub, SubRip, MicroDVD extensions and more.
Overall, ffmpegX is a thoroughly versatile media converter that is best suited to an advanced user. However, the application is still in its early stages of development and it will become more appealing to users in the future.
