How to open .UVVV files on Windows
To open .UVVV files on Windows, check the file’s origin: if it came from a DECE/UltraViolet workflow or a system that labels it as UltraViolet video, keep it with its accompanying assets/metadata rather than moving it alone.
Step-by-step instructions
- Check the file’s origin: if it came from a DECE/UltraViolet workflow or a system that labels it as UltraViolet video, keep it with its accompanying assets/metadata rather than moving it alone.
- If double-clicking does not work, try opening it from within the application or system that produced/exported it (a DECE/UltraViolet-aware workflow is typically required), or inspect it as video/vnd.dece.video in your tooling that relies on MIME types.
Common issues
Nothing plays or the device says the file is unsupported
Many media players and mobile apps do not recognize .uvvv by extension, and DECE video tracks may be tied to a controlled playback environment rather than generic playback.
- Verify whether the file is part of a DECE/UltraViolet workflow/package and keep any associated files together.
- Handle the file as media type video/vnd.dece.video in your software stack (player/tooling must explicitly support this DECE type).
Web/server delivery uses the wrong Content-Type
If a server sends .uvvv as a generic type (or as a different video type), clients and downstream processors may mis-handle it. Tooling commonly maps .uvvv to video/vnd.dece.video.
- Configure your web server or application to serve .uvvv as video/vnd.dece.video.
- Confirm your pipeline recognizes the extension-to-MIME mapping used in common tooling for .uvvv.
File appears to be “MP4” but still won’t open
Some environments label UltraViolet-related files as MP4 video, but DECE specifications emphasize the DECE media type and parameters (including encryption flags). If encryption or DECE-specific signaling is present, a generic MP4 player may still fail.
- Check whether the DECE media parameters indicate encryption or a profile/codec combination your player doesn’t support.
- Use a workflow or toolchain intended for DECE/UltraViolet content rather than relying on a generic “MP4-capable” app.

Recover a deleted or lost .UVVV file
If the file was deleted by mistake or the drive was formatted, data recovery software may be able to get it back. Stop writing to that drive right away, because new data can overwrite what you want to recover.

Security note
.uvvv is associated with DECE video tracks and may involve encryption and controlled playback; avoid renaming it to a common extension to “force” playback, since that can confuse tools and lead to risky trial-and-error with untrusted parsers.
