Convert to VOB
Video is re-encoded using the selected output’s defaults. Image quality, audio and metadata can change. Check playback and duration in the application where you will use it.
Download and check the result
Use Download after conversion completes. Open the result and check its content, quality and formatting before sharing it. Download links expire one hour after upload finishes. Uploaded and converted files are removed automatically by regular cleanup. Files may become unavailable sooner when the service restarts.
Tips for Converting WMV to VOB
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
WMV Video has a known limitation: proprietary format with poor cross-platform compatibility. DVD Video Object addresses this with a key advantage: standard format for DVD-Video ensuring universal DVD player compatibility. Converting from WMV to VOB is most worthwhile when this specific trade-off matters for the way you intend to use the file.
Match the format to the actual workflow
WMV Video is most commonly used for legacy windows video libraries and media collections, while DVD Video Object is the standard for dvd-video disc content storage and playback. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where WMV is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the VOB output
DVD Video Object has its own limitation worth understanding before you commit: mPEG-2 video compression is inefficient by modern standards. After the conversion completes, open the VOB file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.
Avoid transcoding unless necessary
Every time you transcode (re-encode) a video, some quality is lost unless you use a lossless codec. If you only need to change the container format without changing the codec, use a remux (stream copy) operation instead of a full re-encode. This preserves original quality and is much faster.
Understanding WMV and VOB Formats
Learn about the source and target file formats to understand what happens during conversion.
Source Format
WMV Video
video/x-ms-wmvWMV (Windows Media Video) is a proprietary video compression format developed by Microsoft, based on the Advanced Systems Format (ASF) container. It was designed for streaming and local playback on Windows platforms and includes built-in DRM support for content protection. WMV has largely been superseded by H.264/MP4 for most modern use cases.
Advantages
- Good compression efficiency, especially at low bitrates
- Native support in Windows Media Player and Windows ecosystem
- Built-in DRM support for protected content distribution
Limitations
- Proprietary format with poor cross-platform compatibility
- Not supported on iOS, many Android players, or web browsers without plugins
- Declining usage and relevance in modern video workflows
Common Uses
- Legacy Windows video libraries and media collections
- DRM-protected video content from older platforms
- Windows-based screen recordings and presentations
Target Format
DVD Video Object
video/dvdVOB (Video Object) is the container format used on DVD-Video discs, containing multiplexed MPEG-2 video, audio (AC3, DTS, or MPEG), subtitles, and navigation data. Each VOB file typically represents a portion of the DVD content, with files limited to approximately 1 GB due to the UDF filesystem used on DVDs. VOB files can include copy protection data such as CSS encryption.
Advantages
- Standard format for DVD-Video ensuring universal DVD player compatibility
- Supports multiple audio tracks, subtitle streams, and navigation menus
- Well-established format with decades of player and software support
Limitations
- MPEG-2 video compression is inefficient by modern standards
- CSS copy protection can prevent direct playback or conversion
- Limited to DVD resolution (720x480 NTSC or 720x576 PAL)
Common Uses
- DVD-Video disc content storage and playback
- DVD ripping and backup operations
- Legacy video archival from DVD collections
