iSpConverter vs MPO Viewer

Transform your photos and videos into immersive spatial experiences — or extract side-by-side (SBS) content from spatial media — right on your iPhone or iPad. iSpatialConverter is the essential tool for spatial video and spatial photo enthusiasts. Whether you want to view your memories on Apple Vision Pro, share SBS files with 3D video players, or prepare footage for professional editing in DaVinci Resolve, iSpatialConverter has you covered. KEY FEATURES Spatial Video -> SBS: Extract left/right eye frames from Apple spatial videos (MV-HEVC) into a standard side-by-side MP4 or MOV file compatible with any 3D player or NLE. SBS -> Spatial Video: Convert side-by-side videos into Apple-standard MV-HEVC spatial video. Compatible with iPhone 15 Pro / 16, Apple Vision Pro, and DaVinci Resolve. Spatial Photo -> SBS: Decompose Apple spatial HEIC photos into a flat SBS image. SBS -> Spatial Photo: Create Apple-standard spatial HEIC photos from side-by-side images. Full Parametric Control: Adjust horizontal FOV, stereo baseline, and disparity to perfect your 3D depth. Resize & Crop: Output at any resolution with Stretch, Crop-Fill, or Letterbox modes. Left/Right Swap: Fix reversed stereo pairs with one toggle. Audio Preservation: Keep original audio tracks during video conversion. Photo Library Integration: Pick source media directly from Photos via PHPicker, and save results automatically to named albums (ConvSBS or ConvSpatial). On-device Processing: All conversion happens locally — no uploads, no subscriptions, no internet required. PERFECT FOR Apple Vision Pro owners who want to convert their 2D/3D content library Videographers and photographers working with spatial media DaVinci Resolve editors who need Vision Pro-compatible spatial video 3D enthusiasts with SBS content collections TECHNICAL NOTES Spatial video conversion (SBS → Spatial) requires iOS 17.0 or later. Photo conversion is available on iOS 16.0 and later. Output videos are stored in your Photos library under the ConvSBS or ConvSpatial album.

MPO Viewer opens your stereoscopic 3D photos and video straight from the camera. No conversion, no computer. A dual-lens camera such as the Fujifilm FinePix REAL 3D W1 or W3 saves each photo as an .mpo file holding both eyes, and MPO Viewer shows that pair in six 3D modes and plays the stereo video those cameras shoot. VIEWING Point it at a folder of .mpo photos or .avi clips, on your device or in iCloud Drive, and browse a searchable grid or table. Open any photo in the mode that suits you: • Side by Side: the classic pair, for free-viewing or a stereo viewer • Crossed Eye: the same pair swapped, for cross-eyed viewing • Cardboard (experimental): the pair bent beforehand so the lenses of a cheap VR viewer straighten it out again, set to your own viewer • Anaglyph: both eyes merged for coloured glasses (Red/Cyan, Magenta/Green, Amber/Blue or Red/Blue), with eye swapping and ghost reduction • Wiggle: the two eyes flicker back and forth, on a timer or as you tilt the phone • Depth (experimental): a depth map built from the pair, warped as you tilt Stereo clips play with sound in Side by Side, Crossed Eye, Cardboard and Anaglyph. Whichever mode you pick, the pair is corrected first: the eyes are brought into line vertically and the nearest thing placed at the screen plane, which is what keeps the depth comfortable. Hide a photo or clip and the Hidden list brings it back, behind Face ID if you want. An info button shows what the camera recorded, down to lens, aperture, shutter and ISO, with a map when there is a location. WATCHING TOGETHER A few red/cyan glasses and a television make a stereo evening for the whole room. Mirror to an Apple TV or AirPlay television, or plug in HDMI: the picture moves to the big screen and the phone becomes the remote. Swipe, run a slideshow, play a clip with sound. Set the depth once per television and every photo is placed for that screen from then on. STEREO CARDS AND READY MADE PAIRS Old stereo cards become MPOs too, from any mount or an archive scan. Convert a photo of a card and the two prints are found by their edges, straightened and registered on each other, with the colour cast of the lamp taken out. Every card then carries three buttons of its own: turn it over, put the light back, or save it without colour. Or photograph one in the app, inside the frame it draws. A converted card can be coloured by a machine learning model on the device. The card itself is never touched. A picture that already holds the pair side by side goes in the same way. The app works out which of the two it has, finds the two panels and writes the MPO. Each row says what it decided; one button overrules it either way, another swaps the eyes, and one more cuts a picture down the middle on your word. FRAMES, SLIDESHOWS AND PLAYLISTS Frame photos and clips with a plain border in a colour of your choosing, or one of six passepartouts, from a stereo card to a cardboard peep box. Caption any photo; the caption takes a colour of its own. Run a slideshow through a folder, or save a selection as a playlist: the library then shows just that list, in your order, from the start or shuffled. SHARE AND EXPORT Side by Side, Crossed Eye and Anaglyph export as PNG or JPEG, Wiggle as an animated GIF or a cross-faded video, Depth as an MP4 tilt-sweep. Cardboard exports the plain pair. A clip exports as MP4 at three sizes, with or without its sound. Exports carry a watermark; MPO Viewer Pro removes it. ACCESSIBILITY Works with VoiceOver, the largest text sizes and Reduce Motion, where Wiggle and Depth follow your tilt instead of moving by themselves. Both work with one eye. PRIVACY Your photos never leave your device. No accounts, no analytics, no data collection. The one thing the app ever fetches is a larger colour model, only when you ask. In English and Dutch, for anyone rediscovering a box of old stereo photos and anyone still shooting 3D.
