Media Coder is a free software that converts the format of audio and video files. Use it if you have devices which only support a specific type of extension.

The interface may be a little overwhelming at first, especially for rookies, because there are so many featured included here. But advanced users will surely get a kick out of MediaCoder.

You first need to select the source file you wish to convert, whether it's a video or audio track, the format of the output file, additional settings if you want to, and Start Transcoding (or hit F5 on your keyboard).

MediaCoder supports a lot of formats, but not all commonly used ones can be found here, which is a pity.

There are a lot of additional features for each file type. For example, if you want to convert something to XviD format, you can enable high quality mode, greyscale, cartoon, quarter-pixel, or global motion compensation, while a FLAC output file's compression level can be configured.

The time for each file to complete conversion is excellent, and the quality is fairly maintained overall (as much as it can be).

While MediaCoder is busy converting something, CPU and memory resources are minimally consumed.

MediaCoder generally has a lot of functions, and these are usually explored only by expert users. But if you ever feel overwhelmed at some point, you can view the online support forum, or just switch to simple interface mode.

So, if you want an effective software that will convert your multimedia files, MediaCoder comes in handy. Again, too bad it's not compatible with more file extensions. But at least it's free!
