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
| Item | Options / range | Details / conditions |
|---|---|---|
| Playback speed | 0.25–3×; step 0.05× | Pitch compensation; reset to 1×. |
| AI mask size | 256 / 320 / 384 / 512 | Square model inputs; global preference. A new size may need initial preparation. |
| AI frame-rate limit | 10–40 FPS; step 1; initial default 30 | An upper limit, not guaranteed throughput. Existing saved choices remain. |
| Alpha feather / edge erosion | Each 0–100%; step 1% | Refine the AI outline; defaults are 100% feather and 40% erosion. |
| Video / photo AI depth | 0–200% | Flat mono media; video and photo preferences are separate. Native stereo media uses its own display path. |
| Flat-video distance | 0.8–8 m; step 0.1 m | Applies to the flat screen; immersive projection has different controls. |
| Flat-video screen size | 40–300%; step 5% | Relative screen size, distinct from photo size. |
| Video rotation | −90° to +90°; step 1° | Text subtitles stay upright. |
| Photo distance / size | 0.3–10 m / 40–600% | Single-photo adjustment; group layouts have their own placement. |
| Photo magnifier / wall | 2–8× / 1–3 rows | The magnifier is independent of overall photo scaling. |
| Subtitle sync | −10 to +10 s; step 0.1 s | Remembered separately for each subtitle of a video; positive delays, negative advances; reset to zero. |
| Text size / colors | 50–200%; step 5% / 5 styles | Text and outline styles; PGS retains its own palette. |
| Immersive text placement | 0.1–5 m; elevation −60° to +60° | Horizontal/vertical text; near placement should be adjusted for comfort. |
| Stereo alignment | Horizontal / vertical ±5%; step 0.05% | Per-video display offsets; does not change the headset IPD. |
| Fisheye angles | 180° / 190° / 200° / 220° | Choose the angle matching the source; available controls depend on its mode. |
| Color and display quality | Color presets / custom; independent sharpness and supersampling | Exposure, contrast, temperature, gamma, saturation and RGB controls; some effects require a costlier display path. |
| Playback memory | Per-video modes, tracks, subtitle timing and AI 3D choice | A newly opened video does not inherit manually enabled people passthrough. |
| Favorites PIN | 4 digits | Encrypted app collection; source media remains unchanged. A short PIN is not strong protection against offline guessing. |
| Favorites auto-lock | Relaxed 15 min / standard 2 min / strict immediate / manual until exit | Manual locking is also available; playback-history settings are independent. |
| Playback-history privacy | All / local only / none | Clear existing network or all history separately, without removing saved accounts or favorites. |
| Spatial-source matching | Recommended stereo offset / capture FOV when valid | Video 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.
Sources and library capabilities
| Item | Options / range | Details / conditions |
|---|---|---|
| Local / read-only USB | Local files; compatible FAT32/exFAT/NTFS drives and partitions | USB is read-only. Some system volumes need folder permission. Stop-all releases app access, not system power/unmount. |
| SMB / WebDAV | Network folder browsing and compatible remote playback | Permissions, seeking and writes depend on the source. |
| DLNA / Thru3D Server | Discovery, manual address entry and advertised subtitle resources | For Server people passthrough, select its compatible Alpha output. |
| Media servers | Emby / Jellyfin / Plex / Stash / XBVR | Capabilities vary; source-supported favorites do not imply full playback-progress writeback. |
| Cloud drives | 115 / Baidu / Aliyun / Quark / OneDrive | On-demand pages, supported sorting/search. Manual subtitle choices use the opened page; supported automatic discovery can target matching companions across pages. |
| STRM / companion files | Compatible indexed links, subtitles and matching dubbing audio | Access and discovery still depend on the underlying source. |
| File actions | Opt-in multi-select deletion, rename preview and companion-file linking | Source/permission dependent; 115 Open rename support is distinct from older cookie access. |
Operation guide
| Item | Options / range | Details / conditions |
|---|---|---|
| Select and open controls | Controller ray + matching trigger; supported pointing/pinch input | Menus are selected by pointing. Sticks scroll lists. |
| Play / library / back | Default right A / left X / B or Y | A plays/pauses video or collapses an opened photo. B/Y returns by context; ordinary video returns to the library. |
| Move and change distance | Hold grip; same-hand stick up/down | Grip moves panels/flat screens or rotates immersive media. Trigger-drag flat-video corners to scale; saved custom controls remain. |
| Seek | Preview target, return stick to center to commit | Defaults: left 20 s, right 10 s per step. Lists/settings/pointer capture isolate playback shortcuts. |
| Photo gestures / shortcuts | Pinch-drag, two-hand scaling; double-click 3D or volume icons | 3D toggles its effect; volume toggles mute. Button combinations are configured by scene. |
Compatibility and support scope
| Item | Options / range | Details / conditions |
|---|---|---|
| Headsets | QUEST / PICO; experimental OpenXR Android | Minimum targets: Quest 2 / PICO Neo3. Quest 3 / PICO 4 Ultra recommended for AI; not every device/effect is equally verified. |
| Blu-ray / MVC | Unencrypted main features; progressive 720p/1080p MVC, 8-bit 4:2:0 | Compatible multi-clip layouts only. No disc menu/decryption or promise of standalone MVC MKV/TS compatibility. |
| Spatial video and color | MV-HEVC software stereo; HEIC/HEIF spatial photos | Device-dependent software playback. Valid metadata enables source matching, not full Apple spatial presentation/true scale. Spatial photos output sRGB; DV P5 color is not HDR certification. |
| Subtitles | Text subtitles and flat-video PGS | ASS/SSA text does not imply full style/effect rendering; immersive PGS is outside the stated scope. |
| Alpha / head following | Compatible packed masks; supported single-content following | Not every Alpha layout or chroma-key source. No permanent room anchors or head-locked full photo walls. |
| Favorites and playback scope | App favorites PIN; video previous/next and repeat-one | Original 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.
