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.

Convert Ogg Video to MKV online free, no account required — MKV is a flexible open container for video with any number of audio and subtitle tracks.

Why won't my video editor or iPhone open my OGV file? The Theora-based format never left the browser world, so most hardware and software can't decode it — converting to MP4 or WebM makes it playable.

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.

Why convert video to MKV? When one file must carry several audio languages, subtitle tracks and chapters, no container holds them as flexibly.
