.UVV file extension
To open .UVV files on Windows, check what application is currently associated with .uvv (Right-click the file → Properties → “Opens with”).
To open a .uvv file, use software or a device implementation that recognizes DECE/UltraViolet CFF video (MIME video/vnd.dece.video). If your usual media player does not recognize it, the file is likely meant for a specific UltraViolet/DECE ecosystem workflow rather than generic playback.

How to open .UVV files
Use these platform-specific instructions to open .UVV files safely.
Windows
- Check what application is currently associated with .uvv (Right-click the file → Properties → “Opens with”).
- If it does not open, look for a DECE/UltraViolet CFF-capable player or device software in your environment and open the file from within that software (or set it as the default app for .uvv).
- If you do not have DECE/UltraViolet-compatible software, treat the file as a specialized vendor video container and use a desktop system that supports video/vnd.dece.video in your workflow.
Mac
- Try opening the file with the application that originally produced or delivered it (for example, a DECE/UltraViolet-capable workflow tool).
- If double-clicking fails, use “Open With…” to test any DECE/UltraViolet-aware media application you have available; general players may not recognize .uvv.
- If no compatible software is available on macOS, transfer the file to the system or device environment that is documented to support DECE CFF video.
Linux
- Identify the file’s intended workflow (DECE/UltraViolet CFF video with MIME video/vnd.dece.video) and try opening it with software in your environment that explicitly supports that vendor type.
- If you cannot find DECE/UltraViolet CFF support on your Linux setup, use a supported device/software stack that recognizes .uvv per the DECE device specification.
iOS
- iOS apps generally will not recognize .uvv unless they explicitly implement DECE/UltraViolet CFF; if it does not open, move the file to a desktop or device environment that supports video/vnd.dece.video.
Android
- Android players typically will not recognize .uvv unless they explicitly implement DECE/UltraViolet CFF; if it does not open, use the software/device stack that provided the file or supports video/vnd.dece.video.
Security notes
- .uvv is a video container format identified as video/vnd.dece.video; while it is not an executable type, malformed or maliciously crafted media files can still target vulnerabilities in media parsers. Prefer opening it only in trusted, up-to-date DECE/UltraViolet-capable software.
- Be cautious with files labeled .uvv that come from untrusted sources: the extension is uncommon, and some files may simply be renamed content that is not actually DECE CFF video.
- If a website or app asks you to install unrelated codecs or “special players” to open a .uvv file, treat that as suspicious; rely on known DECE/UltraViolet implementations in your environment.
Can't open this file?
These are the most common causes and fixes when .UVV files fail to open.
Common reasons
- “Can’t open file” or the OS doesn’t know what a .uvv file is
- File opens in the wrong application
- A player treats it as a generic video file but playback fails
Fix steps
- Confirm the file is intended to be a DECE CFF video file (extension .uvv and vendor media type video/vnd.dece.video are expected per DECE specs).
- Open it using the DECE/UltraViolet-capable application or device workflow that supplied the file, or set that application as the default for .uvv on your system.
Recover a deleted or lost .UVV 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.

OS-specific troubleshooting
What is a .UVV file?
A .uvv file is a DECE Common File Format (CFF) video file; DECE device specifications state devices shall recognize DMP files with the .uvv extension and the Internet media type video/vnd.dece.video. The extension-to-MIME association is also reflected in widely used MIME mapping tables.
Background
The .uvv extension is defined by the DECE/UltraViolet specifications as the required file extension for DECE Common File Format video files. In DECE documentation, it is tied to the vendor media type video/vnd.dece.video.
In practice, .uvv files are part of a standards-based packaging and delivery approach for video in the DECE/UltraViolet ecosystem. Because the format and its handling are defined through DECE device and media format specifications, whether you can play one depends heavily on whether your playback software or device stack implements DECE CFF support.
Outside DECE/UltraViolet-aware environments, .uvv files may not open in mainstream players simply because the extension and media type are specialized. When troubleshooting, the most important diagnostic is whether the tool you are using recognizes video/vnd.dece.video (or explicitly claims DECE/UltraViolet CFF support).

Common .UVV issues
“Can’t open file” or the OS doesn’t know what a .uvv file is
.uvv is a specialized DECE/UltraViolet CFF video extension and may not be registered with common media players. Many general-purpose players do not associate themselves with video/vnd.dece.video.
- Confirm the file is intended to be a DECE CFF video file (extension .uvv and vendor media type video/vnd.dece.video are expected per DECE specs).
- Open it using the DECE/UltraViolet-capable application or device workflow that supplied the file, or set that application as the default for .uvv on your system.
File opens in the wrong application
If another program has claimed the .uvv extension, double-clicking may launch an unrelated app that cannot parse DECE CFF video.
- Change the default “Open with” association to the DECE/UltraViolet-capable software you use for video/vnd.dece.video.
- If you do not have any compatible software installed, remove the incorrect association and handle the file only in the intended DECE workflow.
A player treats it as a generic video file but playback fails
Even though .uvv maps to a video/* MIME type, it is specifically video/vnd.dece.video; software that does not implement DECE CFF details may fail to parse or play it correctly.
- Do not rely on file extension alone; ensure the software explicitly supports DECE/UltraViolet CFF or video/vnd.dece.video.
- Use the device/software environment defined for DECE CFF playback or processing.
FAQ
What kind of file is .uvv?
.uvv is a DECE/UltraViolet Common File Format (CFF) video file extension. DECE specifications associate it with the Internet media type video/vnd.dece.video.
What MIME type is associated with .uvv?
DECE documentation and common MIME extension maps associate .uvv with video/vnd.dece.video.
Why won’t VLC/QuickTime/other common players open my .uvv file?
.uvv is a specialized DECE CFF vendor format (video/vnd.dece.video). If a player does not implement DECE CFF support, it may not recognize the structure or required handling even though it is “a video” file type.
Is .uvv the same as .mp4?
The DECE specs treat .uvv as a DECE Common File Format video file identified by video/vnd.dece.video. It should be handled as its own vendor-defined format rather than assumed to be a generic .mp4.
