Technical Details
Container Format Conversion
WMV uses Microsoft’s Advanced Systems Format (ASF) container, while MKV utilizes the open Matroska container. This conversion preserves video streams (typically WMV9/VC-1 codec) and audio streams (Windows Media Audio) while repackaging them into the more flexible MKV structure that supports multiple tracks and enhanced metadata.
Codec Compatibility Handling
During conversion, Windows Media Video codecs (WMV7, WMV8, WMV9) are either preserved within the MKV container for maximum quality retention, or optionally transcoded to more universal codecs like H.264 or H.265 for broader compatibility. The process maintains original resolution, frame rate, and bitrate specifications.
Metadata and Stream Preservation
The conversion process carefully extracts and transfers all embedded metadata including title, artist, duration, and creation date from the WMV file’s ASF header to the MKV container’s metadata blocks. Audio streams, video parameters, and any existing subtitle tracks are preserved with full fidelity during the container migration.

Frequently Asked Questions
Will converting WMV to MKV reduce video quality?
No quality loss occurs when converting WMV to MKV, as this is primarily a container format change. The video and audio streams are typically preserved exactly as they were in the original WMV file, maintaining identical resolution, bitrate, and codec specifications.
Can MKV files play on Windows Media Player after conversion?
Windows Media Player has limited MKV support depending on your version and installed codecs. However, MKV files play perfectly in VLC Media Player, Media Player Classic, and most modern media players, offering better compatibility than the original WMV format.
How large will my MKV file be compared to the original WMV?
The converted MKV file will be nearly identical in size to the original WMV file when no transcoding occurs. The MKV container is actually more efficient, potentially resulting in slightly smaller files while maintaining the same quality and content.
Does the conversion preserve metadata like title and creation date?
Yes, all embedded metadata from the WMV file including title, artist, description, creation date, and technical specifications are carefully extracted and transferred to the MKV container’s metadata blocks during conversion.
Can I convert DRM-protected WMV files to MKV format?
No, WMV files with Digital Rights Management (DRM) protection cannot be converted as they are encrypted and protected by Microsoft’s Windows Media DRM system. Only unprotected WMV files can be successfully converted to MKV format.
Will subtitles embedded in WMV files transfer to MKV?
Yes, any embedded subtitles in the WMV file will be preserved and transferred to the MKV container. Additionally, MKV format supports more subtitle formats and multiple subtitle tracks, offering enhanced flexibility for multilingual content.
How long does it take to convert a WMV file to MKV?
Conversion speed depends on file size and your computer’s processing power, but most WMV to MKV conversions complete within seconds to minutes. Since this is primarily a container change without transcoding, the process is much faster than quality-altering conversions.
Can I batch convert multiple WMV files to MKV simultaneously?
Yes, Convertify supports massive batch processing, allowing you to convert thousands of WMV files to MKV format simultaneously. The multi-threaded processing engine handles large batches efficiently without crashes or memory issues.
