Description
Like the MKV file extension, the WEBM royalty-free extension is developed by various online parties such as Google. It is a freeware offering streaming of online video content. It was first developed in 2010. By using the HTML5 version of YouTube, one can watch videos encoded in WEBM.
Technical details
Encoding and decoding in open-source WEBM video format are possible while using the ffvp8 software or libvpx from the Google support. When it comes to the Android, support a version of 2.3 (Gingerbread) and above, allowing playback of WEBM format can be used for encoding and decoding. Back in 2001, using Rockchip, a full hardware implementation of 1080p VO8 encoding was made possible. The video element of the file is encoded using VP8 video codec, and the audio component of the file is encoded using the Vorbis audio codec. It provides open video compression for HTML5 videos, and most major web browsers support WebM as a part of HTML5 video delivery. However, some programs like Quicktime and browsers like Internet Explorer and Safari do not have native WebM support. Fortunately, the Google WebM Project Team released plugins for Internet Explorer and Safari in 2011 to allow WebM files' playback through the standard HTML5 video tag.

Matroska Video File

Description
MKV Matroska is an open-source multimedia container format that supports more than one audio and subtitle tracks in the same file. It is the most convenient file type where you can add a large sum of data, such as videos, audios, texts, and various images. It is a RAW format which you can later flip and separate based on needed data tracks.
Technical details
Whether it is video, audio, subtitle, or image, every file will be stored in a separate data line. It is a lot similar to the MP4 or AVI format, although when users are packaging an MKV file, they rarely bundle all the tracks within the file. Various media players don't even support the MKV video format; therefore, the users need to use specialized media players who can help the MKV format, such as VLC media player.
