.UVH file extension
To open .UVH files on Windows, if the .uvh file came from a specific streaming or media workflow, open it in that same toolchain (or import it into the application that generated/downloaded it).
To open a .uvh file, try importing it into the player or workflow that produced it, or use a desktop video tool that can handle UltraViolet/DECE HD segments. If your usual media players won’t open it, treat it as a specialized streaming asset and consider converting or handling it within its intended pipeline rather than renaming the extension.

What “reviewed” means on this page
- Format fit: whether the “what is this file?” description matches common real-world use of the extension, including category, typical MIME types, and aliases.
- Opening paths: whether Windows / macOS / Linux steps read plausibly for current OS dialogs and default apps; we remove fantasy menus and unsafe shortcuts.
- Security framing: whether risk notes match the extension class (for example executables vs plain data) and whether affiliate wording does not contradict the security section.
- Sources and further reading: whether external links point to vendors, standards bodies, or other primary references where possible; we avoid inventing details we cannot ground.
- Limits: this is clarity and safety-messaging QA, not a guarantee that every statement is exhaustive or that every binary you download is harmless.

How to open .UVH files
Use these platform-specific instructions to open .UVH files safely.
Windows
- If the .uvh file came from a specific streaming or media workflow, open it in that same toolchain (or import it into the application that generated/downloaded it).
- If double-clicking fails, right-click the file → Open with… and try a video/packaging tool you already trust that can handle vendor-specific media types (video/vnd.dece.hd).
- If it still won’t play, treat it as a segment and look for accompanying streaming files (such as a manifest) from the same source; the segment may not be playable by itself.
Mac
- Try opening the file from the originating workflow/application (the one that produced or delivered the .uvh segment).
- Control-click → Open With… and test with trusted media tooling you already have installed; many general-purpose players may not support vendor-specific segment formats.
- If there are related streaming/playlist files from the same package, open the manifest/playlist instead of the .uvh file directly.
Linux
- Check what your desktop thinks it is: view file properties and look for the MIME type (often expected to be video/vnd.dece.hd for .uvh in DECE/UltraViolet contexts).
- If it isn’t associated, set an application association manually (your desktop uses the shared-mime-info database rules for extension/MIME mapping).
- If playback fails, assume it is a streaming segment and try opening the accompanying manifest/playlist file from the same set, not the .uvh segment alone.
iOS
- iOS typically won’t have common native support for specialized DECE/UltraViolet segment files; if it won’t preview in Files, transfer it to a desktop system or open it within the specific app/workflow that provided it.
Android
- Android players often won’t recognize specialized .uvh DECE/UltraViolet segments; if it won’t open, move the file (and any related manifest/segment files) to a desktop system or use the originating app/workflow that delivered it.
Security notes
- .uvh files are video data, but media parsers can have vulnerabilities; only open .uvh files from sources you trust, especially if your player or toolchain is outdated.
- Be cautious with “codec packs” or unknown third-party apps that claim to open every video format; prefer reputable software and keep it updated.
- If a .uvh file arrives alongside a streaming package (manifest/playlist plus many segments), treat the whole set as untrusted input and avoid running any included executables or installers that may be bundled with downloads.
Complex decoders and untrusted media
Image, audio, and video decoders are large software surfaces; issues are uncommon for everyday files but show up with crafted files from unknown sources. Keeping the OS and media apps updated matters most; scanning is reasonable extra caution for downloads you cannot vouch for.

Can't open this file?
These are the most common causes and fixes when .UVH files fail to open.
Common reasons
- The .uvh file won’t play in common media players
- The file opens in the wrong app (or shows as an unknown file type)
- You only received a single .uvh file and nothing else works
- Renaming .uvh to .mp4 doesn’t help
Fix steps
- Look for companion streaming files from the same source (for example, a manifest/playlist) and open that instead of the .uvh segment.
- Try opening/importing the file in the same software/workflow that created or downloaded it.
- If you must make it playable elsewhere, use a trusted conversion/packaging workflow from the original toolchain rather than renaming the extension.
OS-specific troubleshooting
What is a .UVH file?
.uvh is associated with “DECE High Definition Video” used in UltraViolet/DECE streaming contexts. The DECE Streaming Protocol specification references .uvh alongside mimeType="video/vnd.dece.hd", indicating it is meant to be identified and processed as a specific HD video media type. In practice, .uvh files may be media segments or components that rely on a surrounding streaming manifest/workflow to play correctly.
Background
.uvh is most often encountered as part of Digital Entertainment Content Ecosystem (DECE) / UltraViolet-related streaming assets. In that context, it is not necessarily a single, standalone “movie file” intended for double-click playback; it may be a segment or track used by a streaming system.
From a standards perspective, the DECE Streaming Protocol documentation explicitly ties UltraViolet/DECE HD video segments to the media type video/vnd.dece.hd and the .uvh extension, which helps systems identify the content correctly. This is also consistent with extension-to-MIME mappings reported by third-party file identification references.
On Linux desktops, file extension recognition typically depends on the shared-mime-info database (and its specification), which determines how environments map extensions to MIME types and select default applications. If .uvh isn’t recognized on your system, you may need to set the association manually or rely on the producing application’s tooling.
Common MIME types: video/vnd.dece.hd

Common .UVH issues
The .uvh file won’t play in common media players
.uvh is commonly used as a DECE/UltraViolet HD streaming segment type (video/vnd.dece.hd), which many consumer players don’t support directly or don’t treat as a standalone video file.
- Look for companion streaming files from the same source (for example, a manifest/playlist) and open that instead of the .uvh segment.
- Try opening/importing the file in the same software/workflow that created or downloaded it.
- If you must make it playable elsewhere, use a trusted conversion/packaging workflow from the original toolchain rather than renaming the extension.
The file opens in the wrong app (or shows as an unknown file type)
Your system may not have an extension→MIME mapping or default app association for .uvh. On Linux desktops this typically depends on shared-mime-info mappings and your chosen default applications.
- Manually choose the app: Open with… and select the correct tool for the workflow that uses the file.
- On Linux, verify the system’s MIME handling/associations and set a default application for the detected MIME type (often video/vnd.dece.hd in DECE contexts).
You only received a single .uvh file and nothing else works
In streaming workflows, a single segment may be incomplete without the rest of the package (additional segments, manifest/playlist, metadata).
- Ask the sender/source for the complete set of files required by the stream (not just one .uvh).
- Re-download or re-export the content from the original source to ensure all related assets are included.
Renaming .uvh to .mp4 doesn’t help
Changing the filename extension doesn’t convert the underlying format, and players will still fail if the internal structure isn’t MP4 (or if the file is only a segment).
- Restore the original extension and handle it as a DECE/UltraViolet HD video segment.
- Convert/export using an appropriate tool in the original workflow, if conversion is necessary.
FAQ
What does .uvh stand for or mean?
In common usage it is associated with DECE (UltraViolet) High Definition Video content and is tied to the vendor media type video/vnd.dece.hd.
What is the MIME type for .uvh?
In the DECE/UltraViolet streaming context, .uvh is associated with the MIME type video/vnd.dece.hd.
Why won’t my phone open a .uvh file?
Mobile platforms typically support mainstream consumer formats; .uvh is often a specialized DECE/UltraViolet segment type. If it won’t preview or open, move it (and any related manifest/segments) to a desktop system or use the original app/workflow that produced it.
Can I convert a .uvh file by renaming it to .mp4?
No. Renaming only changes the label, not the actual video/segment format. Use an appropriate conversion or export process from the original workflow if you need another format.
