Thru3D Media Player

Full features. Every setting in view.

Explore AI passthrough, spatial media, Blu-ray 3D, cloud browsing, read-only USB and private favorites. Regular features describe 0.11.1; newer audio work is listed separately as a development preview.

Feature scope 0.11.1QUEST / PICOOn-headset AI

Complete features

Video formats and stereo

  • Flat, VR180, 360°, fisheye, side-by-side and top-bottom stereo, including half/full layouts and eye swap.
  • Automatic mode detection, manual mode lock, per-file viewing memory and horizontal/vertical stereo alignment.
  • Compatible unencrypted Blu-ray and MVC 3D ISO main features, including supported multi-clip playlists, audio selection and seeking.

AI people passthrough and Alpha

  • Live AI background removal for supported VR180 and spatial videos; ordinary flat photos can be prepared as 3D portraits.
  • Adjust model size, mask feathering, edge erosion and the processing frame-rate limit. Unsupported runtimes fall back to the supported rendering path.
  • Compatible full side-by-side fisheye videos can use a built-in packed Alpha mask instead of live AI; the choice is remembered per video.

Apple spatial media and AI 3D

  • Native MV-HEVC video and HEIC/HEIF spatial photos; valid source data enables recommended stereo offsets for videos and capture-FOV matching for videos/photos.
  • On-headset 2D-to-3D for flat mono videos and photos, with adjustable strength and independent video/photo preferences.
  • Spatial videos can use supported people-passthrough processing. Native stereo photos do not use the ordinary-photo AI portrait route.

Photos and immersive galleries

  • Flat and panoramic photos, side thumbnails, a one-to-three-row Photo Wall and Memory Fragments.
  • Pinch and drag to browse, two-hand resizing, group switching, an independent magnifier, adjacent-image preloading and 3D caching.
  • Keep photo layouts and placement; use a selected 360° panorama as the Player background.

Libraries, sources and search

  • Local files, compatible read-only FAT32/exFAT/NTFS USB drives, SMB, DLNA, WebDAV, STRM and cloud/server integrations.
  • Emby/Jellyfin posters, landscape cards and lists with size preferences, cast links, multi-image details, filters, sorting and multi-part selection.
  • On-demand cloud pages and service-supported sorting, keyword/type search, library context retention and compact/full browsing during playback. WebDAV reuses loaded directory snapshots.

Audio, subtitles and dubbing

  • Choose other same-folder text subtitle files, including alternate names/versions; audio/subtitle selection and per-subtitle timing are remembered.
  • Adjust text size/color/position/distance and horizontal/vertical layout. Flat-video PGS remains visible in supported 2D-to-3D playback and retains its palette.
  • Matching .si.mix.m4a tracks from VR Video Toolbox CUDA, variable playback speed and pitch compensation.

Viewing, controls and file tools

  • Screen position, scale, rotation, curvature and color controls, independent sharpness/supersampling and supported compositor display with fallback.
  • Session head following for flat video, single/portrait photos and menus; an independent environment-passthrough switch.
  • Scene-specific buttons and combinations, grip movement, bookmarks, resume/history, previous/next, repeat-one, rename previews and multi-select deletion where supported.

Personal favorites and privacy

  • Save videos, photos and folders, return to the source directory, batch-remove records and undo recent removals without deleting original files.
  • Choose all/local/no history and clear network/all history independently of saved accounts and active favorites.
  • Protect the app collection with a four-digit PIN, encrypted storage, manual lock and automatic-lock policies; locked protected playback closes.

Read-only USB and comfortable controls

  • Read compatible FAT32, exFAT and NTFS drives/partitions with media and same-folder subtitles. Stop all app USB access with one global action.
  • Resize a flat video proportionally from its corners with a trigger; the default right stick adjusts screen size or immersive zoom.
  • Deliberate movement/button presses wake controller rays; multi-row photo navigation keeps its row and 3D photos switch only when ready.

Adjustable parameters

ItemOptions / rangeDetails / conditions
Playback speed0.25–3×; step 0.05×Pitch compensation; reset to 1×.
AI mask size256 / 320 / 384 / 512Square model inputs; global preference. A new size may need initial preparation.
AI frame-rate limit10–40 FPS; step 1; initial default 30An upper limit, not guaranteed throughput. Existing saved choices remain.
Alpha feather / edge erosionEach 0–100%; step 1%Refine the AI outline; defaults are 100% feather and 40% erosion.
Video / photo AI depth0–200%Flat mono media; video and photo preferences are separate. Native stereo media uses its own display path.
Flat-video distance0.8–8 m; step 0.1 mApplies to the flat screen; immersive projection has different controls.
Flat-video screen size40–300%; step 5%Relative screen size, distinct from photo size.
Video rotation−90° to +90°; step 1°Text subtitles stay upright.
Photo distance / size0.3–10 m / 40–600%Single-photo adjustment; group layouts have their own placement.
Photo magnifier / wall2–8× / 1–3 rowsThe magnifier is independent of overall photo scaling.
Subtitle sync−10 to +10 s; step 0.1 sRemembered separately for each subtitle of a video; positive delays, negative advances; reset to zero.
Text size / colors50–200%; step 5% / 5 stylesText and outline styles; PGS retains its own palette.
Immersive text placement0.1–5 m; elevation −60° to +60°Horizontal/vertical text; near placement should be adjusted for comfort.
Stereo alignmentHorizontal / vertical ±5%; step 0.05%Per-video display offsets; does not change the headset IPD.
Fisheye angles180° / 190° / 200° / 220°Choose the angle matching the source; available controls depend on its mode.
Color and display qualityColor presets / custom; independent sharpness and supersamplingExposure, contrast, temperature, gamma, saturation and RGB controls; some effects require a costlier display path.
Playback memoryPer-video modes, tracks, subtitle timing and AI 3D choiceA newly opened video does not inherit manually enabled people passthrough.
Favorites PIN4 digitsEncrypted app collection; source media remains unchanged. A short PIN is not strong protection against offline guessing.
Favorites auto-lockRelaxed 15 min / standard 2 min / strict immediate / manual until exitManual locking is also available; playback-history settings are independent.
Playback-history privacyAll / local only / noneClear existing network or all history separately, without removing saved accounts or favorites.
Spatial-source matchingRecommended stereo offset / capture FOV when validVideo offset is optional per file; FOV matching applies to supported videos/photos with capture data, not a generic true-scale reconstruction.

Regular parameters describe release 0.11.1; packages vary by channel. Development-preview features are not included in that release. Settings are not performance guarantees.

Alpha / head followingCompatible packed masks; supported single-content followingNot every Alpha layout or chroma-key source. No permanent room anchors or head-locked full photo walls.
Favorites and playback scopeApp favorites PIN; video previous/next and repeat-oneOriginal media is not encrypted. No claim of complete cross-page video auto-next or full server progress sync. Audio preview modes are separate from video playlists.

Development preview

Development builds only, not included in standard 0.11.1 packages. Headset coverage, sustained performance and release availability remain under validation. No voice pack or model download is offered on this page.

On-device subtitle narration

  • Read selected subtitle text aloud locally, with voice selection, audition, narration volume and original-audio ducking.
  • Prepared cues follow the video clock; paused-video auditions are separate. Cold starts or seeks may skip unprepared cues.
  • Current device work is Quest 3 development validation, not all-headset or arbitrary-language/zero-latency certification.

Unified audio library and playlists

  • One logical playback channel for music or ambience, six built-in music pieces and six ambience recordings, shared by the home player and photo controls.
  • Create/reorder playlists, browse the library/queue and choose list repeat, single repeat or shuffle. Playback pauses for video or lost app focus.
  • Import MP3, Ogg Vorbis or WAV from local/USB/SMB/cloud/WebDAV into complete persistent local copies for offline use; current per-file guard is 64 MB. No Android background service after app exit.
