No codec packs, no plugins. FFmpeg-powered decode covers H.264, H.265 / HEVC, AV1, VP9, MPEG-2 and ProRes out of the box - no Microsoft Store extension required. 3D Blu-rays play in real 3D: both MVC eye views decode natively, also from MKV and M2TS files that keep the MVC track. HDR10 and HLG playback preserves the source's full 10-bit precision end-to-end. 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. Dolby and DTS tracks - Atmos, TrueHD and DTS-HD included - can also be passed through untouched for an AV receiver to decode.

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.

Demo

No installation.

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

It's a demo, not the full thing. It's based on an older build and is missing many of the newer features. It also 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, you can chip in via PayPal or Buy Me a Coffee - entirely optional.

Just about anything - here's how each kind of source is handled:

  • 2D videos, films & games - converted to 3D by the AI in real time, on any content.
  • Side-by-side & top-bottom 3D - played natively, exactly as mastered - the depth AI stays off.
  • VR180 / VR360 (stereo) - played natively, no VR headset required - navigate with mouse and keyboard, or put on a headset.
  • iPhone Spatial Videos & Spatial Photos - both eyes decoded in stereo, with no conversion step - HEIC photos open directly, no JPEG conversion needed.
  • Photos with their own depth map - iPhone depth photos, Leia LIF files, and photos with a depth file beside them use that depth instead of an AI estimate - and the format menu lets you flip between the two.
  • 3D Blu-rays (ISO, BDMV, MKV, or M2TS with an MVC track) - both eye views decoded natively. Unencrypted discs only - a copy-protected disc shows a notice instead of playing.
  • Live streams (HLS, RTMP, RTSP, DASH, MPEG-TS) - converted in real time, with a live-edge badge on the player bar.
  • Netflix, YouTube & other DRM video - via screen capture - point Oku3D at the browser window. Subject to the service's DRM.
No. The native app runs its AI on DirectML, so any modern DirectX 12-capable GPU works - whatever the brand (NVIDIA, AMD, Intel, and even integrated graphics), no CUDA required. The browser demo uses WebGPU and is just as vendor-agnostic.
It depends on the look you want. 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. On any regular screen, anaglyph output with 14 color modes (Red-Cyan, Green-Magenta, Amber-Blue, and more) works with the matching inexpensive glasses. You can also play to a VR headset (Meta Quest, Valve Index, HTC Vive, and other OpenXR headsets) on a virtual cinema screen, or use Oku3D purely as a native side-by-side player on any monitor that accepts SBS input.
You have room to tune it. Oku3D offers 13 depth models from lightweight (fast) to heavy (higher quality), each with its own inference resolution - a smaller model at a lower resolution runs on most modern integrated graphics. The model comparison puts every model and resolution side by side with measured speed and memory use, and the Help page walks through what to lower first.
Mostly yes. AI models are downloaded once on first use (18 MB to 1.8 GB depending on your selection - the default Depth Anything V2 Small is 47 MB). The download runs in the background while you keep watching, and can be paused and resumed. After that, Oku3D runs completely offline - no phone-home, no cloud dependency.
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.
Point Oku3D's screen capture at the game and it converts the 2D image to 3D in real time - no SBS mod or 3D patch needed. Games in windowed or borderless mode capture directly. A game that only runs in exclusive fullscreen needs one extra step: add a free virtual display with the open-source Virtual Display Driver (run its VDD Control app and click Install Driver), make that virtual display the one the game opens on - set it as your main display, or pick it in the game's video options - run the game there, and capture that display. Either way you watch the 3D on your real monitor while keyboard, mouse, and controller keep driving the game, all on a single-monitor setup.
