Free Online XVID to MKV Converter

XviD is a codec based on the MPEG-4 standard. The codec distorts colors but it has high definition in dynamic scenes. XviD is constantly updating because it is an open source codec and anyone who is interested can participate in the development of the program. Using XviD may be illegal in some countries because the compression methods used in MPEG-4 are patented.

MKV is an open source container that can contain media data compressed with a use of different codecs. It has a lot of advantages over the legacy AVI container: it can contain audio tracks and subtitles in different languages, that can be switched without stopping the playback, file seek and rewind are very fast. Also the format is easy to edit, that is why audio and video data can be extracted effortlessly.
