About Matroska (MKV)
Matroska (MKV) is an open container format that can hold almost any video and audio codec, any number of audio and subtitle tracks, chapters and attachments.
It is popular for films and series with several audio languages and subtitle tracks, and for archiving video.
Many phones, browsers and TVs do not play MKV files directly, even when they support the codecs inside.

About Ogg Video
Ogg Video (OGV) is the open Ogg container from the Xiph.Org Foundation holding Theora video, usually with Vorbis audio.
Open-source projects and Wikimedia Commons, which accepts video only in free formats.
Theora compresses less efficiently than modern codecs, and Apple devices do not play OGV natively.
