Convert WTV to MKV — Free Online Converter

WTV (Windows TV) is the DVR container format from Windows Media Center, storing broadcast TV recordings with MPEG-2 or H.264 video, AC3 or AAC audio, EPG metadata (program title, description, channel, ratings), and closed caption streams. The NTFS-like internal structure supports multiple audio tracks and subtitle streams within a single file. MKV (Matroska Video) is the modern open-source multimedia container, supporting virtually any combination of video, audio, subtitle, and metadata streams without codec restrictions.

Windows Media Center recorded millions of hours of personal TV content from 2007 until its discontinuation in Windows 10. MKV represents the ideal modern container to receive this content, matching and exceeding WTV's multi-stream capabilities with universal player support.

MKV is the premier format for preserving the full richness of WTV TV recordings. Unlike MP4 or AVI, MKV supports multiple audio tracks (preserving all language options from the broadcast), subtitle streams (closed captions), chapter markers, and extensive metadata — closely matching the multi-stream structure of WTV itself. This makes MKV the highest-fidelity container conversion available.

MKV plays on VLC, MPV, Kodi, Plex, Jellyfin, and all major media server platforms. Converting a Windows Media Center archive to MKV preserves everything that can be preserved while ensuring compatibility with modern home theater and media server setups.
