About OGV to MKV Conversion
OGV uses Theora video with Vorbis audio in the Ogg container, while MKV (Matroska Video) is an open-source multimedia container that can hold virtually any codec combination. Both OGV and MKV are open-source formats, but MKV offers significantly more features: multiple audio/subtitle tracks, chapter markers, attachments, and support for modern codecs like H.264, H.265, VP9, and AV1.
Why Convert OGV to MKV?
MKV replaces OGV's limitations while keeping everything in the open-source ecosystem. Theora's compression efficiency is poor by modern standards — converting OGV to MKV with H.264 or VP9 video produces dramatically smaller files at better quality. MKV also enables adding multiple subtitle tracks, audio languages, and chapter markers that OGV's simple structure cannot support.
For media servers like Plex, Kodi, and Jellyfin, MKV is the preferred container format with full metadata and subtitle support.
