Watch everything
in 3D.
Real-time AI depth conversion turns any video or image into stereoscopic 3D - while you watch. Native stereo playback even for VR180° and VR360°. Free.
Built for
One player for all of 3D.
Real-time conversion, native stereo playback, every format, any GPU - in a single app that costs nothing.
Real-time
2D to 3D.
Any video or image - movies, YouTube, Netflix via screen capture, webcam, photos - converted to stereoscopic 3D on-the-fly using AI depth estimation. No rendering. No waiting. No upload.
The only free alternative that works on AMD and Intel GPUs - no NVIDIA required.

Frame layouts
Immersive Stereo
Full spherical stereoscopic 3D - a rare feature among desktop players. Fisheye footage plays as the sphere its lens covers, and a 360° recording still holding its two raw lens circles is stitched on the fly
3D Blu-ray
Both MVC eye views decoded natively - no open-source player can
Display output
3D scans
A Gaussian splat opens like any other file - a captured place you move through, not a picture you watch. No other player in the comparison below opens one.
Scene formats
The scene builds up while it loads, so you can look around it before it is finished. One split into a folder of pieces opens as the whole place, and one too large for the graphics card drops to a coarser level of detail instead of refusing
Moving through it
Walk through the scene, or circle whatever is in front of you. A gamepad works with nothing to set up first, and on a glasses-free 3D display leaning to the side is enough to look past a foreground object.

2D converts to 3D in real time. Side-by-side, top-bottom, VR180, VR360 and fisheye play natively, exactly as mastered - the depth AI stays off. MK3D, ISO, BDMV and SSIF carry a 3D Blu-ray, and both eye views decode natively.

Any still image converts to 3D the same way a video frame does - a phone snapshot, a scan, or a 32-bit workstation file.
Stereo & depth · 7 file types
These already hold two eye views or a depth map, so they show as captured rather than as an AI estimate - Apple Spatial Photos, Samsung Galaxy 3D photos and iPhone depth photos included. The format menu switches between the two.

Gaussian splat scans of a real place. A scan a tool split into a folder of pieces opens as the whole scene, and one too large for the graphics card opens at a lower level of detail instead of refusing.

Album art renders in depth-converted 3D, files without cover art play with a reactive 3D sphere. Multichannel soundtracks play in full 5.1 / 7.1 surround.
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. Unencrypted discs only - commercial discs are AACS-encrypted, Oku3D ships no decryption keys, and such a disc shows a notice instead of playing.
HDR10 and HLG. Playback preserves the source's full 10-bit precision end-to-end.
Cinema audio and subtitles. AC3, DTS and E-AC3 decode out of the box, as do embedded and external subtitles (SRT, ASS, PGS) - which 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.
No 3D glasses yet? perspektrum.de ships affordable anaglyph and polarized glasses across Europe.

Frequently asked
Not while Leia SR displays and VR headsets stay out of reach on a Mac, and not unless someone else carries the cost.
If your hope is to drive a Leia SR glasses-free display or a VR headset from a Mac, neither would work even with a macOS version of Oku3D. The Leia SR platform ships for Windows and Android only, and macOS has no working OpenXR runtime: Valve dropped SteamVR for the Mac in 2020 and nothing replaced it. What would work is anything that does the 3D itself - a 3D TV, a projector, glasses like the XREAL One, or a glasses-free display that does its own conversion. Even then, it would be the most limited version of Oku3D there is.
And even that version would not be free for me: $899 for the cheapest Mac, plus $99 a year to Apple for the right to give away free software. Without that fee, macOS tells anyone who downloads it that the app is damaged. Windows runs an unsigned program with a warning. Linux asks nothing.
The code is not the problem - the Linux port already did most of that work. What it needs is someone to carry the cost. If your company uses Oku3D in a professional setting, or you are interested in a partnership of any other kind, that is the route: jens@oku3d.com.
Nothing is wrong with the download. This is the routine notice for software that does not come through the Microsoft Store, and it stays until Windows has seen that exact file in circulation for a while - so every new Oku3D release starts the clock over.
- Run it anyway - in the "Windows protected your PC" dialog, click More info, then Run anyway.
- If the file is blocked instead - right-click it, open Properties, and check Unblock.
- Check it yourself - upload the file to VirusTotal and let around 70 virus scanners look at it. A couple of them flag anything they have not seen before, so go by the overall picture.
For a free project, the yearly fee of around $140 for a code-signing certificate would confirm who paid it - it would not make the installer any safer, nor would it remove the notice until the file has built up a download history.

Which depth model should I use?
All 13 models Oku3D ships and 63 more it does not, each at every inference resolution, on the same 25 scenes - 8,575 depth maps to flip through side by side, with measured speed and memory for each.

What actually shoots 3D?
34 phones, cameras and headsets from 29 makers record real stereo - most of their owners have no idea. What each one writes, what Oku3D does with it, and how to make any phone do it with an app.
