Every stereo layout, every spatial projection - including immersive VR stereo that VLC cannot play.
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 eye views decoded in full, from an ISO, a disc folder or an MKV - with subtitles at the depth the disc gives them. How it works
Display output
3D scenes
A Gaussian splat scene opens like any other file - a place you move through, not a picture you watch - and any photo can become one. No other player in the comparison below opens one.
Scene formats
A very large scan fills in over a moment once it has been read - across the whole place at once, not corner by corner - and you can already look around while it does. One split into a folder of pieces opens as the whole place, and one too large for the graphics card opens with less 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.
From a photo
One click rebuilds a photo as a scene you step into - move, and what stood behind the foreground comes into view. Built on your own graphics card with Apple's SHARP model, which Apple licenses for non-commercial research use
Photographing it
Frame the scene like a camera and save the shot as a stereo photo - side-by-side, anaglyph, JPS, MPO and more - rendered again at up to eight times the window's size, so it gains real detail.
Photo editor, stereo pairs included
Press E on a photo, 2D or 3D, and finish it right where you view it - light, color, retouching and the 3D itself - then page on to the next photo without leaving the editor. A stereo pair stays in 3D on your screen while you align it. The photo itself never changes: you save a copy, or keep the edits beside it for later.
Aligning stereo photos, step by stepLight & color
Exposure, white balance, curves and color grading as in a photo editor, with looks that preview live and presets of your own. Lens Blur softens the background by the photo's depth, in the style of a real lens - from a swirly vintage lens to an anamorphic one.
Retouch & fix
Remove a speck or a stray object, limit any change to a brushed area, a color or a distance, and level a tilted horizon or a leaning building.
The 3D itself
Straighten a stereo pair that came out crooked, even out the colors of its two eyes, and set where the picture sits in depth. Depth Scope marks the nearest and farthest point and anything that breaks the frame before you save. Where something stands at the wrong distance, paint it nearer or farther by hand - on an ordinary photo and on a real stereo pair alike
Saving it
Export as a 3D photo in the layout your screen or glasses need, as separate eyes, or as an ordinary photo. An HDR photo from an iPhone or an Android phone keeps its bright highlights from opening to saving.

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. Gigapixel panoramas open quickly and show their full detail when you zoom in, and Google and Samsung motion photos play their moment once, with sound, when opened.
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.
3D scenes · 14 file types

Gaussian splat scenes - a scanned real place, or one Oku3D built from a photo. A scene a tool split into a folder of pieces opens as the whole scene, and one too large for the graphics card opens with less detail instead of refusing.
Camera RAW · 31 file types

Opens straight off the memory card with the camera's own colors, with no conversion to JPEG first.

Album art renders in depth-converted 3D. Without cover art, or whenever you pick it instead, music plays in a reactive 3D world - Sphere, Sand Plate, Swarm, Sheet of Light or Arcade Drive, or Auto to follow the song. Multichannel soundtracks play in full 5.1 / 7.1 surround.
CT & MRI · 6 file types
+2 moreShow less
A CT or MRI scan opens as a 3D volume you can turn, cut and step into, in a VR headset too. A DICOM disc opens straight from the drive.
Archives & playlists · 15 file types
+8 moreShow less
Photos, videos and music inside an archive play as a playlist without unpacking. Playlists from other players open too - M3U, PLS, XSPF, WPL, ASX, MPC-HC and PotPlayer lists, IPTV channel lists included - and a CUE sheet lists the tracks of an album.
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.
HDR, 10-bit and wide color. With HDR switched on in Windows, HDR10 and HLG films and HDR photos - Ultra HDR JPEGs, iPhone photos, gain-map AVIFs and HDR PNGs - reach the brightness they were made for, on a glasses-free 3D display too. The picture reaches the screen in full precision, so a 10-bit monitor gets smooth gradients and a wide-gamut screen the deep reds and greens of a BT.2020 or DCI-P3 video.
Color grading built in. Give a film or photo one of 13 cinematic looks - Chrome, Bleach Bypass, Hollywood and more - at the strength you want, or fine-tune exposure, gamma, contrast, highlights, shadows and saturation yourself. Each look previews live as you move over it in the list.
Corrected for color blindness. Color Grading recolors the picture for red-, green- or blue-weak vision, so colors you would otherwise confuse stand apart - in a VR headset and on a glasses-free 3D display too.
Cinema audio and subtitles. AC3, DTS and E-AC3 decode out of the box, as do embedded and external subtitles (SRT, fully styled ASS, TTML, PGS) - which even render in stereo 3D, on a 3D Blu-ray at the depth the disc sets, or that OFS files beside a remux restore. 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. A ghosting correction in Settings > Display > Advanced reduces the faint double image some displays leave.
With glasses
Also supports polarized 3D TVs, anaglyph glasses, NVIDIA 3D Vision shutter glasses, 3D projectors over HDMI, and any display that accepts side-by-side input.

Frequently asked
Nothing is wrong with the download. This is the routine notice for software that does not come through the Microsoft Store. Oku3D's downloads are signed, so the notice names the publisher, and it fades as Windows sees more people install files from that publisher - trust that carries over from one release to the next.
- 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 the signature - in the same Properties dialog, the Digital Signatures tab shows who signed the file. A valid signature also means the file has not been changed since it was signed.
- Have it scanned - 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.
The signature confirms who built the file and that nobody has changed it since. No certificate switches the notice off by itself - Windows lifts it once the publisher has built up a download history.
_L / _R - and the photo editor lines up the two eyes (height, tilt, size and keystone) in one click or from points you pick, evens out their colors, and sets the depth and the stereo window. A depth check marks the nearest and farthest point and anything that breaks the frame. The pair stays in 3D on your screen while you edit, and saves as MPO, JPS, PNS, LIF, side-by-side, freeview or separate files. The stereo photo guide walks through it.Yes, 3D movies included. In Settings > Display, set Output Format to Mono and choose the left or the right eye. A side-by-side or top-bottom file, a line-interleaved 3D DVD or a 3D Blu-ray then plays as one normal picture in its correct proportions. VLC, for comparison, usually shows such a file as two pictures next to each other, or striped.
Plain 2D videos open in 3D by default. Turn off Settings > General > Open 2D videos in 3D and they play exactly as they are, while 3D files keep playing in 3D. For a single video or photo, pick Original in the format menu.

Fix a stereo pair that came out crooked
Line up the two eyes, even out their colors, set the stereo window, check the depth, and save as MPO, JPS, LIF or side-by-side - while the pair stays in 3D on your screen. HDR photos stay HDR.

3D Blu-ray, in real 3D
Most players show a 3D Blu-ray flat. Oku3D decodes both eyes from an ISO, a disc folder or an MKV, keeps the subtitles at the disc's depth, and sends the film to a 3D TV, a projector, a glasses-free monitor or a VR headset.
