3D camera motion capture with iPhone ARKit for AI style transfer
Film space is built for AI video workflows. Block a scene in 3D, then walk through it with your phone in Camera mode to perform real-world camera motion. Record that footage and bring it into a tool like Seedance 2.0 — the recording gives the model a clear reference for your blocking and camera path, so you can map the motion you performed in real life onto a stylized or generated output.
Under the hood it's a lightweight virtual studio: grid floor, human stand-ins, lens presets, and on-device recording to your photo library.
Film space gives you a lightweight staging environment for blocking and camera exploration:
- AI style transfer workflow — Record your scene here, then use that clip as a motion/camera reference in tools like Seedance 2.0 to apply a new look while preserving the path you walked in real life.
- Virtual studio — A 3D space with a checkerboard floor, grid, and axis guides so you can orient subjects and camera positions.
- Human stand-ins — Add, select, rotate, and reposition figure placeholders to block talent in the scene.
- Edit mode — Orbit around the studio, zoom in and out, and arrange your blocking from a bird's-eye or close-up view.
- Camera mode — Carry your phone through the scene. Physical movement translates into camera movement; tilt and turn to look around, as if you're operating a real camera on set.
- Lens simulation — Cycle through 35mm, 50mm, 75mm, and 200mm focal lengths to preview different fields of view.
- Recording — Capture the rendered scene (with microphone audio) and save the video to your photo library.
Film space runs entirely on your device. Landscape orientation is recommended.
The toolbar at the bottom of the screen holds all controls. Some buttons change depending on whether you're in Edit or Camera mode.
| Control | Action |
|---|---|
| Edit | Stage the scene — orbit the view, move stand-ins, and set up your blocking. |
| Camera | Walk through the scene using device motion and record footage. |
| Gesture | Action |
|---|---|
| Drag (no stand-in selected) | Orbit the camera around the scene. |
| Pinch | Zoom in and out. |
| Tap a stand-in | Select it for editing. |
| Tap empty space | Deselect the current stand-in and return to orbiting. |
| Drag (stand-in selected) | Move the selected stand-in across the floor. |
| Control | Action |
|---|---|
| ↺ / ↻ (hold) | Rotate the selected stand-in counterclockwise or clockwise. Requires a selected stand-in. |
| Figure | Add a new human stand-in to the scene. |
| Trash | Delete the selected stand-in. Requires a selected stand-in. |
| Control | Action |
|---|---|
| ↑ / ↓ (hold) | Raise or lower the camera framing (moves the orbit center vertically). |
| Joystick | Move the camera rig horizontally and forward/backward relative to the current view. |
| Lock | Save the current camera viewpoint. Use this to mark a shot you want to return to. |
| Return | Snap back to the locked viewpoint. Disabled until you've set a lock. |
In Camera mode, move through the virtual space by physically walking and turning with your phone. The app uses ARKit device tracking to translate your real-world movement into camera movement in the scene.
| Control | Action |
|---|---|
| Focal length (e.g. 35mm) | Tap to cycle through 35mm → 50mm → 75mm → 200mm lenses. |
| Control | Action |
|---|---|
| Shoulder placement | Place the camera at shoulder height (~1.5 m) at the scene center, using your phone's current tilt and heading. |
| Lock | Save your current camera position and orientation as a return point. |
| Record | Start or stop recording. While recording, the button shows a square stop icon. Video is saved to your photo library when you stop. |
| Return | Snap the camera back to the locked viewpoint at your current physical position. Disabled until you've set a lock. |
