About formats

WMV (Windows Media Video) is a family of video codecs and associated file format developed by Microsoft, first introduced in 1999 as part of the Windows Media framework. The format encompasses several codec generations, from the original WMV 7 through WMV 9 (also standardized as VC-1 by SMPTE under the 421M specification). WMV files are typically contained within the ASF (Advanced Systems Format) wrapper and use the .wmv extension to indicate video content. WMV 9/VC-1 achieved compression efficiency comparable to early H.264 implementations, delivering good visual quality at moderate bit rates and earning adoption for HD DVD and Blu-ray disc content as an approved codec. The format was deeply integrated into the Windows operating system, Windows Media Player, and server-side streaming infrastructure, making it a natural choice for enterprise media delivery, corporate training videos, and Windows-centric web content throughout the 2000s. WMV supports features including interlaced video, multiple bit rate encoding for adaptive streaming, and digital rights management through Windows Media DRM. The Silverlight platform also used WMV as its primary video format for rich internet applications and streaming services. While the industry has largely moved to H.264 and HEVC for most applications, WMV remains present in legacy enterprise content management systems, archived media libraries, and workflows tied to the Windows Media ecosystem.

DVMS (Dutch Voice Messaging System) is a telephony-grade audio encoding born from the Netherlands' early push toward digital voicemail infrastructure. Deployed through KPN (formerly PTT Telecom) in the mid-1980s, the format stores mono voice data at a narrow 8 kHz sample rate, prioritizing compact message size over sonic breadth. Audio is compressed with a proprietary variant of logarithmic companding similar to European A-law encoding, squeezing recordings to roughly 8 kbit/s while keeping speech intelligible. Each file carries a small header identifying sample rate, compression type, and message metadata, which made automated routing across early PBX and voicemail systems straightforward. Although DVMS never gained traction outside Dutch telecom circles, it influenced how European carriers designed later voice messaging protocols. Tools like SoX and several legacy telephony libraries still read and write DVMS files, allowing archival playback of decades-old messages. Among its practical advantages: extremely small file sizes (a one-minute message occupies roughly 60 KB), reliable speech clarity despite aggressive compression, and a simple container layout that is easy to parse programmatically.

Frequently Asked Questions

Why convert WMV to DVMS?

DVMS provides telephony voice messaging format, which WMV cannot offer due to poor Mac, Linux, and mobile device support. The conversion bridges that gap.

How do I open a DVMS file?

For DVMS playback, try SoX or telephony-oriented audio applications. All of these support the format natively or with minimal setup.

Does the conversion work on mobile?

It does. Convertio.tools works in any modern mobile browser — upload your WMV, convert to DVMS, and download directly on your phone.

Can I adjust the output bitrate?

Yes — set the desired bitrate before converting. Lower bitrates produce smaller files, while higher bitrates preserve more audio detail.

How long does the conversion take?

Conversion speed depends on the WMV file size and chosen quality settings. Most files process within seconds to a couple of minutes.

What devices can play DVMS?

DVMS playback requires compatible software on your desktop or laptop. Check the recommended apps above to find the right player for your system.
