Release Notes

What's new in each version of Oku3D.

Preview builds of the next version, with its new features, come out first in #preview-builds on the Discord server.

v4.0.0

Video Export · macOS · Photo Editor · Settings Search · Keyboard Control

Windows: Installer · Portable Linux: .tar.gz · AppImage · Flatpak Linux ARM64: .tar.gz (platform preview) Mac: .zip (first start)

  • Video Export: Ctrl+S or the disk button saves a video's 3D conversion as MP4 or MKV in H.264 or 10-bit H.265, keeping HDR films in HDR except as anaglyph, with a preview of the result, or opens the frame in the Photo Editor.
  • macOS: A native version for Apple Silicon Macs shows 3D on TVs, projectors and video glasses such as XREAL, and converts 2D to 3D on the Mac's graphics chip, but does not output to VR headsets or Leia glasses-free displays.
  • 2D-to-3D: Fences and wire mesh behind people stay straight, depth flickers and bends less, a new shot gets its own depth at once while flashes no longer reset it, and the picture comes further out of the screen.
  • Photo Editor: Edits now show only in the editor, which asks about unsaved changes before closing, Revert to Original removes them all at once, Pick Screen Plane puts what you click on the screen plane, and photos can be edited one after another with Page Up / Page Down.
  • Subtitles: ASS, TTML, IMSC and DFXP subtitles show with their colors, outlines, positions, fonts and animations, TTML at the depth the file gives each line, SRT keeps its italic and colored words, and a switch in Settings > Subtitles puts your own size, color and outline over a file's styles.
  • Subtitle Lines: Ctrl+T or the subtitle menu lists every line of a subtitle track, finds lines by any text in them or by a time, and jumps to the one you click.
  • Settings Search: A search field at the top of Settings, or Ctrl+F, finds any setting even with typos or in English, and a button in it lists every setting you changed.
  • Video Playback: A film at 24 frames a second is now drawn 24 times a second instead of at every screen refresh, which takes load off weaker computers, and the performance panel's Render rate counts the frames actually drawn.
  • Video Resolution: A change in Settings > Display now takes full effect without reopening the video, and on Windows a lower setting no longer adds processor load to hardware-decoded videos.
  • HDR Photos: Ultra HDR JPEGs, iPhone photos, gain-map AVIFs and HDR PNGs open in HDR as bright as saved, the Photo Editor saves HDR photos as HDR PNG too, and its HDR switch takes SDR photos beyond white.
  • Playlist: A button beside the source button opens the playlist to select, add, remove, drag or sort entries and stop after the last file (Settings > General), PLS, XSPF, WPL, ASX, MPC-HC and PotPlayer playlists open and save alongside M3U, and CUE sheets list an album's tracks.
  • Side Panels: Widen a panel by its edge, move it or the control bar as a remote into its own window, or keep the picture beside the panels (Settings > Display).
  • VR Headset: Control bar and side panels stand beside the cinema screen, the grip moves a panel, and recentering while lying down turns the screen to your eyes.
  • Depth: A switch in Settings > Depth reads photos' depth in overlapping tiles for crisper 3D edges, and ZipDepth is a new, faster depth model for weaker graphics.
  • RGB-D: RGB-D videos and photos with their own depth map get the depth cleanup of 2D-to-3D.
  • Keyboard Control: Tab, the arrows and F6 move through panels, dialogs and the control bar, a gamepad D-pad or VR thumbstick through them too, and typing jumps through lists.
  • Media Controls: The media keys, the system's media panel and the lock screen control playback on Windows, and Stop works like Esc.
  • 3D Format: A tag like _SBS in a folder name now applies to every file inside, and Apply to All Files in the format menu covers the whole playlist.
  • Timeline: Ctrl+G or a click on the time opens a field that jumps to a time you type, and videos that store no length, such as raw .h264 and .265 streams, show one marked with ~ where estimated and can be jumped in.
  • 3D Camcorder Video: More interlaced 3D camcorder recordings, such as AVCHD 3D clips, play in real 3D instead of opening in 2D.
  • 3D Blu-ray: Disc images and folder copies of 3D Blu-rays that lack the interleaved .ssif files now play in 3D instead of 2D.
  • Lytro Light Field Photos: Photos from the Lytro Illum open in real 3D too, and all Lytro photos open faster.
  • Frame Packing: On Windows, the picture now also goes out through the 3D modes a TV's graphics driver offers, such as NVIDIA 3DTV Play.
  • Audio Device: Settings > Audio picks the device the sound plays on, such as a VR headset while other programs keep the speakers.
  • Installation: On Windows, the installer can set up Oku3D for all users of a computer, who then share every AI model they download.
  • Mouse Pointer: Instead of shaking the mouse, hold L and turn the wheel to enlarge the pointer, add Alt or AltGr to color it, and tap L to reset it.
  • Acer SpatialLabs: On Windows, Intelligence 3D in Acer's SpatialLabs 3D Hub now keeps Oku3D's fullscreen side-by-side video in 3D.
  • Other Improvements: The Depth slider ending at 2 %, an Eye Distance slider, a soft fade to full sharpness for splats, on Windows more 3D laptops and monitors found and the whole log in crash reports, files in 3D sooner, a fuller Ctrl+P report and a performance test.
  • Fixed - 2D-to-3D: Still backgrounds could pump while people moved, fast objects left a smeared trail, and on Linux, video could skip frames on weaker graphics at a high depth resolution and some older graphics cards showed an error instead of 3D.
  • Fixed - HDR: With Windows HDR on, HDR videos, photos, and screen captures looked darker than in other programs and changed brightness with the Windows SDR brightness slider.
  • Fixed - Photo Editor: With Windows HDR on, brightened photos looked oversaturated, with hard-edged Lens Blur highlights, unlike on an SDR monitor and in the exported file.
  • Fixed - Lens Blur: Blurred people before a blurrier background could get ragged outlines, the edge of a subject in focus could look stair-stepped with green or dark fringes, thin parts could blur away, and Light Boost made fog, signs, and sky glow over everything around them.
  • Fixed - Gaussian Splats: Scenes flickered while a slider was dragged, could look doubled on glasses-free 3D displays, barely answered the convergence slider once walked through, and a focus click could blur its spot.
  • Fixed - 3D Format: Some 2:1 films in 4K that start on a blank picture opened as VR180 video.
  • Fixed - Window Size: On Windows, after a switch to a smaller monitor, the player window could open larger than the screen, with its bottom edge out of reach.
  • Fixed - Subtitles: Lines beside a subtitle shown for over a minute could go missing, and after some jumps in a film, subtitles came several seconds late.
  • Fixed - Title Bar: In the Flatpak on Ubuntu and Debian with GNOME older than version 48, the mouse pointer disappeared over the title bar.
  • Fixed - Blu-ray: On some 3D discs, subtitles stayed flat, or Settings > Subtitles > Depth plane offered none of the planes in the video.
  • Fixed - Other: Further fixes for 3D Vision, audio sync, seeking, TV recordings, HLS, ProRes on Linux, VC-1, photo depth maps, 3D detection, music visualizer, Ogg audio, swapped eyes, mouse pointer on Windows, glasses-free 3D keyboard focus, and Motion-Sync 3D.

v3.2.0

Photo Editor · Music Visualizer · CT & MRI in 3D · Archives · Playback Speed · Color Blindness

Windows: Installer · Portable Linux: .tar.gz · AppImage · Flatpak Linux ARM64: .tar.gz (platform preview)

The previous release, for going back if the current one gives you trouble.

  • Photo Editor: E or the pencil button opens a 2D or 3D photo in a built-in editor - light and color, masks, retouching, Lens Blur, 3D alignment, depth painting, crop, and export as a 3D photo, HDR included.
  • Music Visualizer: Besides the sphere, music now plays in four new 3D worlds - Sand Plate, Swarm, Sheet of Light, and Arcade Drive - picked in the menu above the track or left on Auto, which follows the song.
  • CT & MRI in 3D: CT and MRI scans from a DICOM disc or a NIfTI, NRRD, or MetaImage file open as a 3D volume to turn, cut, and step into, in VR too.
  • Archives: Photos, videos, and music inside ZIP, CBZ, TAR, and GZ files play as a playlist without unpacking.
  • Playback Speed: The ] and [ keys play videos and music from 0.25x to 4x, with voices keeping their pitch.
  • Color Blindness: Color Grading in Settings > Image corrects the picture for red-, green-, or blue-weak vision.
  • Glasses-Free 3D In HDR: With Windows HDR on for the 3D display, HDR films and photos keep their bright highlights in 3D.
  • NVIDIA 3D Vision: On Windows, a new fullscreen output drives 3D Vision shutter glasses through NV3D-Glass.
  • Ghosting Correction: A slider in Settings > Display > Advanced reduces the faint double image on glasses-free 3D displays.
  • 3D Comfort Warning: The depth, convergence, and subtitle depth sliders mark where the 3D becomes uncomfortable.
  • 2D-to-3D Conversion: Black bars around a video no longer flatten its 3D, and on Linux with NVIDIA graphics the depth can update up to 50% more often.
  • Playlist: Ctrl+L shows the playlist in a side panel, and M3U and M3U8 playlists, IPTV lists included, now open.
  • Frame Step: The . and , keys step one frame forward or back.
  • Crop Black Bars: Shift+C crops off the black bars around a video or picture.
  • Swap Eyes: F7 swaps the left and right eyes of the picture.
  • Subtitles: The size and position sliders now also apply to Blu-ray and DVD subtitles, and a subtitle file dropped on a playing video is added as a track.
  • 3D Subtitles: 3D Blu-ray subtitles also take their depth from OFS files, and depth authored on the disc is kept exactly.
  • Large Photos: Huge photos up to gigapixel size need far less memory and show their full detail when zoomed in, and gigapixel JPEGs and PNGs open several times faster.
  • Network Drives: When a network share or slow drive stalls, playback waits and continues where it stopped.
  • Faster Start: Oku3D opens sooner, uses less memory, and is about 27 MB smaller to download.
  • 3D Blu-ray Playback: 3D Blu-rays play with much less processing power.
  • ARM64: On Linux, a highly experimental download for ARM64 computers.
  • Optimized Anaglyph: The new default Red-Cyan (Optimized) mode keeps colors true with less ghosting.
  • Convergence Per Video: With Save per file on, videos remember their convergence as photos do, except Blu-ray discs and streams.
  • Motion Photos: Google and Samsung motion photos play their moment once when opened.
  • Other Improvements: A Gamma slider in Settings > Image, shaking the mouse to enlarge the pointer, Postshot projects, RAW photos from recent cameras, transparent pictures on a checkerboard, sharper SVGs, an update notice in Settings, and a fuller Ctrl+P report.
  • Fixed - 2D-to-3D Conversion: Large depth models could make the picture stutter on Windows 11, and on Linux with integrated graphics a Lotus-D photo could end the desktop session.
  • Fixed - VR Headset: On integrated graphics, videos in a VR headset could stutter heavily.
  • Fixed - 3D Detection: Untagged side-by-side or top-bottom videos could open as 2D when they began dark or blurred.
  • Fixed - Seeking: In some MP4, AVI, AVCHD, Blu-ray, and Vivo videos, jumps could stall the picture, be refused, or freeze the player.
  • Fixed - Audio Sync: On some Blu-rays, the sound ran more than a second ahead of the picture after a jump.
  • Fixed - 3D Blu-ray Playback: Played from a slow Blu-ray drive, a 3D Blu-ray hitched every few seconds.
  • Fixed - Subtitles: In a subtitle file beside a video, a line after a pause in the dialogue could show minutes early.
  • Fixed - Screen Lock: On Linux with XFCE and some other desktops, the screen could lock in the middle of a video.
  • Fixed - Other: Further fixes for rotated photos, playlists, folders, opening files, large photos, glasses-free 3D displays, Gaussian splats, screen sharing, capture sound, the clipboard, cropping, the mouse pointer appearing on file changes, and keyboard shortcuts.

v3.1.0

HDR Output On Windows · Frame Packing · Photo To Gaussian Splatting · Multiple Instances

  • HDR Output: On Windows with HDR on, HDR10 and HLG films and HDR photos reach their full brightness instead of an ordinary picture's range.
  • Frame Packing: A new output sends a 3D projector or TV each eye at full resolution over HDMI instead of a halved side-by-side picture.
  • Photo To Gaussian Splatting: A new button turns a 2D photo into a Gaussian splatting scene you can step into, using the Apple SHARP model (1.2 GB download).
  • Multiple Instances: With "Allow multiple instances" in Settings > General, several Oku3D windows run side by side.
  • 3D Detection: 3D photos and videos without a hint in their name now open in 3D by themselves, 360° 3D photos and camcorder recordings included.
  • Splat Photos: Photograph a splat scene with focus and depth of field, and save the shot as a stereo photo, a VR180 or 360° panorama, or RGB-D.
  • Gaussian Splats: Splat scenes move more steadily and open in a better first view.
  • Gamepad: A game controller now runs the whole player, from playback and seeking to 360° views and 3D depth.
  • 3D Camcorder MP4s: MVC MP4s from 3D camcorders play in real 3D at full resolution per eye.
  • Picture Quality: Full 10-bit output, wide-gamut colors on wide-gamut screens, cleaner gradients, and AMD FSR 1 for video smaller than the window.
  • Depth Models: Both Depth Anything V1 models and MiDaS DPT-Hybrid are now Oku3D's own, more accurate builds - pick yours again after the update.
  • 3D Subtitles: Subtitles on 3D Blu-rays and their MKV remuxes reach the full depth the disc asks for, in VR too.
  • Sound Without Picture: A video whose picture cannot be decoded plays its sound with a notice instead of failing.
  • VR Headset: Taking the headset off no longer ends VR output.
  • Verified Publisher: The downloads are digitally signed, so Windows names the publisher.
  • Shortcuts: Fullscreen is no longer on F and stays on F11, double-click, and the button.
  • Delete Key: Deleting the file on screen now takes holding Delete while a ring fills.
  • Other Improvements: MVC and MV-HEVC in the format menu, a link to the AI model folder, 3D DVD subtitles keeping their depth in VR, endless drag on Linux X11, lighter controls and start screen, and a more complete Ctrl+P report.
  • Fixed - Glasses-Free 3D: Resizing the window or moving it to a screen with different scaling could freeze the computer for two seconds and lose the 3D picture until a restart.
  • Fixed - VR Headset: On Linux, switching to or from the headset could garble its picture or close Oku3D, and some VR systems ended VR within a second.
  • Fixed - 3D Conversion: On Linux, a second graphics chip kept the AI 2D-to-3D conversion from starting, and in some 10-bit videos the depth jumped mid-shot.
  • Fixed - MiDaS Models: All three MiDaS models produced less accurate depth than they can.
  • Fixed - HDR Video: HDR videos played slightly too dark.
  • Fixed - Standard-Definition Video: DVDs, camcorder, and TV recordings played with a faint magenta tint.
  • Fixed - Seeking: In some videos without sound, incomplete downloads, old AVIs, long MP4s, and TV recordings, jumps could land late, freeze, or be refused.
  • Fixed - Sound: In videos with few or irregular pictures, such as screen recordings, the sound dropped out for seconds.
  • Fixed - Other: Further fixes for splat scenes, subtitles, 3D detection, MVC and MV-HEVC, photo colors, HDR photos, screen capture, anaglyph, damaged videos, very large photos, opening several files, and settings.

v3.0.0
