WebM (WEBM) is a freely-licensed file container designed for the Web. Specifically, it was designed to be compatible with HTML5, originally. It supports chapters, captions, subtitles, metadata tags, streaming, attachments, 3D codecs, 3D containers, and hardware players. WEBM compresses video streams with VP8 or VP9 codecs, and audio with Vorbis or Opus codecs.
VLC media player and MPlayer can open WEBM files on any operating system (OS). Other good choices for opening WEBM include Winamp for Microsoft Windows OS, and Elmedia for Mac OS X.
Microsoft browsers do not have built-in WebM codecs. Therefore, install the codecs separately. However, most browsers support WEBM files.

Matroska (MKV) is a free, open-source, container standard that can hold an unlimited amount of audiovisual and multimedia files in a single file format. Since it is open source, a user can customize it with open-source software. The name derives from “Matryoshka” dolls, which is a famous type of Russian handicraft that consists of a set of wooden dolls of decreasing size nested one inside another.
The best way to open an MKV file is to use VLC media player. This media player is compatible with all operating systems and platforms. This is important because MKV is not an industry standard, which means that other media players might not support it.
Additionally, MKV does not use codecs to compress file size, which means the file can be quite large. Therefore, another option for opening an MKV file is to download the appropriate codecs that are compatible with the selected media player. To accomplish this, download the Combined Community Codec Pack (CCCP) from a trusted site, such as Ninite.
