MKV is not actually a format. It is an EMBL-based (Extensible Binary meta Language) envelope, which contains audio, video and subtitle streams. MKV files may contain several audio tracks recorded in different languages. You can extract any type of file information you are interested in. Because MKV files are too large for online transmission, they need to be converted to more compact video formats.
Total Movie Converter converts videos in batch. You can check as many files as you need to convert right now and launch conversion. It takes moments for the tool to convert many files in one go. This video converter can be launched from within other programs via command line. Besides, it integrates into the right-button popup menu, so you can convert MKV to AVI right from the desktop.
