.UVVH file extension
To open .UVVH files on Windows, check the file properties (right-click → Properties) and confirm the extension is .uvvh; if Windows prompts “How do you want to open this file?”, it likely has no default association.
To open a .uvvh file, try a video player or media workflow that can handle DECE/UltraViolet HD content and recognizes the MIME type video/vnd.dece.hd. If your system doesn’t know what to do with it, confirm the file is actually DECE HD video and then use a desktop environment where you can test players and associations.

How to open .UVVH files
Use these platform-specific instructions to open .UVVH files safely.
Windows
- Check the file properties (right-click → Properties) and confirm the extension is .uvvh; if Windows prompts “How do you want to open this file?”, it likely has no default association.
- Try opening it from within a capable desktop video player/library manager you already use; if it fails, treat it as DECE/UltraViolet media and look for software/workflows that explicitly support DECE/UltraViolet HD content (video/vnd.dece.hd).
Mac
- Double-click the file; if macOS says there is no application set, stop and verify the file is truly intended to be DECE/UltraViolet HD video (video/vnd.dece.hd).
- Try opening it from within a desktop media player you already have installed; if it won’t open, you may need a DECE/UltraViolet-aware workflow rather than a general-purpose player.
Linux
- Use your file manager or the command line to confirm the extension is .uvvh and that it is intended to map to video/vnd.dece.hd.
- Attempt playback with your installed media player; if it doesn’t recognize the file, look for tools/workflows that explicitly support DECE/UltraViolet HD media types.
iOS
- iOS is unlikely to recognize .uvvh directly; transfer the file to a desktop system first to inspect and attempt playback with DECE/UltraViolet-aware software.
Android
- Android is unlikely to recognize .uvvh directly; transfer the file to a desktop system to inspect and attempt playback with compatible software.
Security notes
- .uvvh is a video-related format mapping (video/vnd.dece.hd). While it is not an executable format, malformed media files can still trigger bugs in media parsers/decoders; open unknown .uvvh files only in trusted, up-to-date players.
- Because .uvvh is uncommon, attackers may use it to bypass simple extension-based filters. Prefer verifying content type (e.g., with MIME-aware tooling) instead of trusting the extension alone.
- DECE/UltraViolet-related files may be part of a broader content/rights ecosystem; avoid installing unknown “codec packs” or random tools claiming to ‘fix’ .uvvh playback unless they are from a trusted source.
Can't open this file?
These are the most common causes and fixes when .UVVH files fail to open.
Common reasons
- “Windows can’t open this file” / no default app
- File opens in the wrong application after choosing an app once
- Player reports unsupported format/codec
Fix steps
- Confirm the file extension is .uvvh and that your workflow expects DECE/UltraViolet HD video (video/vnd.dece.hd).
- Try opening the file from within an existing desktop media player instead of relying on double-click association; if it still fails, you likely need DECE/UltraViolet-specific tooling.
Recover a deleted or lost .UVVH 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 .UVVH file?
.uvvh is mapped in multiple MIME databases to video/vnd.dece.hd, which is the registered media type for DECE High Definition video. UltraViolet/DECE specifications reference this MIME type for HD video signaling in streaming contexts, and DECE documentation describes file-extension requirements for their media formats. In practice, .uvvh is a niche/legacy extension and may not be broadly supported by modern consumer players without the expected DECE/UltraViolet ecosystem.
Background
The .uvvh extension is most commonly associated with DECE (Digital Entertainment Content Ecosystem) / UltraViolet High Definition video. Multiple independent MIME mapping sources (and the IANA media-type registry) align on the identification of this content as video/vnd.dece.hd, which is the standardized media type name used for DECE HD video.
Common MIME types: video/vnd.dece.hd

Common .UVVH issues
“Windows can’t open this file” / no default app
Most systems do not ship with a default association for the niche .uvvh extension, even though it maps to the registered MIME type video/vnd.dece.hd.
- Confirm the file extension is .uvvh and that your workflow expects DECE/UltraViolet HD video (video/vnd.dece.hd).
- Try opening the file from within an existing desktop media player instead of relying on double-click association; if it still fails, you likely need DECE/UltraViolet-specific tooling.
File opens in the wrong application after choosing an app once
Manually selecting “Open with…” can create a file association that points .uvvh at a program that cannot parse DECE/UltraViolet HD video.
- Change the default app association for .uvvh back to “ask each time” or to a more appropriate media tool on your OS.
- Use an application that recognizes the DECE HD media type (video/vnd.dece.hd) rather than a random video editor/player.
Player reports unsupported format/codec
Even if the file is correctly identified as DECE HD video, your player may not support the specific packaging/constraints expected by DECE media formats, or the file may rely on a larger UltraViolet/DECE ecosystem.
- Verify the file really is DECE/UltraViolet HD video (not a mislabeled file).
- Try a different desktop media pipeline/player; if none work, you may need a DECE/UltraViolet-compatible environment rather than a generic player.
FAQ
What does .uvvh stand for?
It is commonly used for DECE/UltraViolet High Definition video and is widely mapped to the MIME type video/vnd.dece.hd.
Is there an official MIME type for .uvvh?
Yes. The IANA media types registry includes video/vnd.dece.hd, and multiple MIME mapping databases associate .uvvh with that media type.
Why won’t my phone open a .uvvh file?
Mobile operating systems typically do not include built-in handling for niche/legacy DECE/UltraViolet extensions. Move the file to a desktop system to inspect and attempt playback there.
