Help - 3DGS Video Creator for Musubi

info About This App

This web app creates rotating and oscillating videos from 3D Gaussian Splatting (3DGS) models, optimized for Looking Glass's new photo frame, "Musubi". It runs entirely in your browser — no installation required, and it works on both PC and Mac.

💡 How Musubi works: "Musubi" is a photo player that overlays a transparent LCD panel on top of a lenticular sheet that creates the illusion of a 3D frame. Brighter parts of the video become transparent, letting the 3D frame behind show through — so a flat 2D video appears to have real 3D depth.

star Key Features

Musubi-optimized recording resolution: Videos are exported at a fixed portrait resolution of 576×1024 pixels, ready to play on Musubi as-is.
Freely adjustable background color: Choose any background color for your 3DGS model. Brighter colors produce a stronger 3D effect, since more of Musubi's transparent LCD shows through.
Adjustments for SHARP-generated models: 3DGS models made from 2D photos using Apple's SHARP often have an off-center rotation pivot. Use the Z Position slider to recenter the subject, and the White Border slider to frame the render and enhance the 3D effect.
Just copy it over USB: Transfer the saved .mp4 file to Musubi via USB and it plays automatically — no conversion needed.

file_open Opening 3DGS Files

You can load models using either of the following methods:

Click the folder icon folder_open on the far left of the toolbar and choose "Open File".
Drag and drop 3DGS files directly onto the viewer.

Supported formats: .ply / .splat / .ksplat / .spz / .sog

📂 Multiple Files: Both methods let you select multiple files at once. When several files are loaded, use the arrow_backarrow_forward (Prev/Next) buttons to switch between them.

apps Toolbar Functions

Icon	Function
folder_open 3DGS	"Open File" (multiple selection supported) and "Save .spz" (converts and saves the loaded model in the compact .spz format).
palette Background Color	Pick any background color with the color picker, or choose a preset with one click: (Default / White / Gray / Black / Green Screen / Blue Screen). Your choice is remembered the next time you open the app.
arrow_back / arrow_forward	Switch between models when multiple files are loaded.
fullscreen Full	Toggle fullscreen display.
play_arrow Auto Play	Choose from four camera animations — Horizontal Orbit, Horizontal Oscillation, Vertical Oscillation, Elliptical Orbit — or Stop.
radio_button_checked Record	Start/stop recording. See "Recording & Transferring to Musubi" below for details.

tune Slider Adjustments

Slider	Range	Description
White Border	0 to 100	Fades a white frame in from the edges of the render. It's alpha-blended so the original image gradually reappears toward the center, which helps emphasize the 3D effect on Musubi. Set to 0 to disable.
Z Position	−3.0 to +3.0	Adjusts the model's front-to-back (Z-axis) position. 3DGS models generated with Apple's SHARP are often off-center, so use this slider to align the rotation pivot with the subject (typically around −1.5 to −2.0).

Click restart_alt to reset both sliders to their default value (0).

movie Recording & Transferring to Musubi

Click radio_button_checked in the toolbar to start recording, and click it again to stop. The elapsed time is shown while recording.
Recording is always captured at 576×1024 pixels (Musubi's optimized resolution), regardless of your window size.
After you stop, "Exporting video…" is shown while the file is being encoded. The button won't respond during this time — that's expected, not a malfunction. Once finished, the .mp4 file downloads automatically.
Files are saved with the name 0000_<timestamp>.mp4.

📼 Playing on Musubi: Just copy the saved .mp4 file to Musubi over USB — no conversion needed, it plays right away.

photo_camera Creating a 3DGS Model from a 2D Photo (Apple SHARP)

To generate a 3DGS model from your own 2D photo, we recommend using Apple's "SHARP". OnnxSharp on Windows and MLSharp on Mac let you generate a 3DGS model directly from a 2D photo.

content_cut Advanced 3DGS Editing (Super Splat)

If you need advanced editing — such as extracting a single subject out of a 3DGS model that captures an entire scene — we recommend the web app "Super Splat". It lets you crop, remove unwanted points, and adjust position/rotation, all in your browser.
