Why Convert Xvid to MKV?

MKV (Matroska) is the most flexible video container — supporting multiple audio tracks, subtitle tracks, chapter markers, and virtually any codec. Converting Xvid to MKV is ideal for archiving with multiple audio languages, adding subtitle tracks to legacy Xvid movies, preserving maximum quality in an open-source container, and organizing media libraries with rich metadata.
