No codec packs, no plugins. Full Chromium media support built in - hardware-accelerated H.264, H.265, VP9 and AV1, with HDR10, Dolby Vision, and HLG playback. Cinema audio (AC3, DTS, E-AC3) and embedded or external subtitles (SRT, ASS, PGS) decode out of the box - subtitles even render in stereo 3D.

Glasses-free 3D

Built for lenticular autostereoscopic displays. Most 3D software ignores this category entirely.

Direct native 3D output on any of these, on any GPU. The 3D screen can be a secondary monitor at any resolution - Oku3D switches it to 3D mode automatically. Samsung's and Acer's own players are vendor-locked to NVIDIA and their own monitors, and won't even launch until you've reconfigured the display by hand.

With glasses

Also supports polarized 3D TVs, anaglyph glasses, and any display that accepts side-by-side input.

Curious how 2D-to-3D conversion looks? Open the browser demo and point it at any video on your machine - no download, no account.

It's a demo, not the full thing. The browser version uses WebGPU and is many times slower than the native Windows app on the same hardware - depending on the GPU, the difference can be more than 30×. For real viewing, the native app is the way.

Frequently asked

Yes. Free to download, free to use - no time limits, no watermarks. If you want to support development, there's an optional donation link.
The native Windows app is the real product - it uses ONNX Runtime with DirectML for AI inference and Media Foundation for hardware video decode, so depth conversion runs many times faster than in the browser. Depending on the GPU, the gap can be more than 30× on the same machine. The browser version exists as a quick-look demo: useful to see the concept without installing, but not meant for actual viewing.
No. Oku3D works on NVIDIA, AMD, and Intel GPUs - the native app uses DirectML for AI inference, the browser demo uses WebGPU. Either way, no CUDA is required.
Yes. This is one of Oku3D's key features. Watch stereoscopic VR180 and VR360 content on your lenticular display or with anaglyph glasses, navigating the scene with mouse/keyboard controls. VLC supports flat 360° but not stereo 360° - Oku3D does.
Yes. The VR Headset (OpenXR) output mode plays flat, side-by-side, top-bottom, and VR180/360 sources on a virtual cinema screen inside Meta Quest, Valve Index, HTC Vive, and other OpenXR-compatible headsets. Screen curvature is adjustable from flat to IMAX-style wraparound, and subtitles float comfortably in front and follow your gaze with a soft lag. The right controller handles pause, seek, volume, recenter, and exit. True wraparound sphere rendering for VR180/360 is on the roadmap for a future release.
Yes - via screen capture. Point Oku3D at the browser window running Netflix or YouTube, and it converts the video to 3D in real time. Note: screen capture is subject to the DRM restrictions of the streaming service.
Mostly yes. AI models are downloaded once on first use (~25-100 MB depending on your selection). After that, Oku3D runs completely offline - no phone-home, no cloud dependency.
Yes. Oku3D offers anaglyph output with 14 color modes (Red-Cyan, Green-Magenta, Amber-Blue, and more) - works on any screen with the matching glasses. Row/column interleaved output supports older passive 3D TVs. Or use it purely as a native SBS/VR360 player on any monitor that accepts side-by-side input.
It depends on your display. Glasses-free lenticular displays (Samsung Odyssey 3D, Acer SpatialLabs, ASUS 3D OLED) need no glasses at all - that's their main appeal. Passive 3D TVs (LG Cinema 3D and similar) work with Oku3D's row/column interleaved output and their included polarized glasses. For anaglyph output, you need matching glasses (Red-Cyan, Green-Magenta, or Amber-Blue) - Oku3D supports 14 color modes that work on any regular screen.
Nothing leaves your computer. All depth estimation and 3D conversion runs locally on your GPU. There are no analytics, no uploads, no telemetry.
Impressive for real-time AI - and continuously improving. Works best on live-action film, TV, and games. Not as precise as a hand-crafted stereo conversion, but no other tool does this live, for free, on any content.
Oku3D offers 10 depth models ranging from lightweight (fast, lower quality) to heavy (slower, higher quality). You can also lower the inference quality (Low / Medium / High) or the render resolution in Settings to reduce GPU load. Smaller models run on most modern integrated graphics.
The interface is available in English, German, French, Spanish, Portuguese, Simplified Chinese, Traditional Chinese, Korean, and Japanese. The app auto-detects your system language on first launch, and you can change it any time in Settings > General. You can also set a preferred audio track language and a preferred subtitle language there, so the matching tracks are selected automatically when opening a video.
First, make sure you're on the latest version - the changelog lists what each release fixes. If the problem persists, you can capture a diagnostic log and send it in: close any running Oku3D instance (end oku3d.exe in Task Manager if the window is unresponsive), press Windows + R, and paste this command into the Run dialog:
cmd /k "%LOCALAPPDATA%\Programs\Oku3D Video Player\oku3d.exe"
A small terminal window will open alongside Oku3D and print any errors. Email the terminal contents to jens@oku3d.com and the issue will be addressed in the next release.
