MKV (Matroska Video) is the open-source universal container that can hold virtually any codec, multiple audio tracks, multiple subtitle tracks, chapter markers, and extensive metadata. RMVB is RealNetworks' proprietary container limited to RealVideo/RealAudio codecs. Converting RMVB to MKV preserves the content in a modern, open container with vastly superior player support — VLC, Kodi, Plex, mpv, and PotPlayer all handle MKV natively.
RMVB requires RealPlayer or specialized decoders. MKV is supported by every major media player and streaming server. Crucially, MKV can hold multiple audio tracks (useful for RMVB files that sometimes include both Chinese and English audio) and subtitle tracks (SRT, ASS) in a single file, something RMVB handles poorly.
FFmpeg decodes the RealVideo and RealAudio streams and re-encodes to H.264 (or H.265) with AAC audio in the Matroska container. MKV's EBML structure supports ordered chapters, segment linking, and extensive metadata. Multiple audio tracks can be preserved or added, and SRT/ASS subtitle files can be muxed into the container.
Re-encoding from RealVideo to H.264 at equivalent or higher bitrates typically improves visual quality — H.264 is significantly more efficient than RealVideo 9/10. At CRF 22-23, the MKV output looks cleaner than the original RMVB, especially in high-motion scenes where RealVideo showed more artifacts.

RMVB to MKV conversion is the ideal migration path for media server users and enthusiasts. MKV's open container, unlimited tracks, and universal player support make it the definitive home for former RMVB content.
