# Video sources and credits

Product interface, fictional patient records, and the reviewed demonstration summary: Harmony Dental Wellness working product demo, using the September 9, 2026 demonstration records. Captures exclude credentials and private patient access links. Interface shots were cropped, resized, and animated in the edit; clinical image content was not generated for the film.

- **Film treatment:** Displayed inside the Harmony viewer, with the demo’s illustrative AI-written guide and focal zoom. This is a public sample unrelated to the fictional patient. The overlay does not perform live image analysis or diagnosis.

## CT and surface model

- **Sample:** CBCTDentalSurgery / PreDentalSurgery, distributed through 3D Slicer SampleData.
- **Catalog:** [3D Slicer SampleData](https://github.com/Slicer/Slicer/blob/main/Modules/Scripted/SampleData/SampleData.py).
- **Original file:** [SlicerTestingData sample](https://github.com/Slicer/SlicerTestingData/releases/download/SHA256/7bfa16945629c319a439f414cfb7edddd2a97ba97753e12eede3b56a0eb09968).
- **License:** 3D Slicer License. The complete license accompanies this film in `Slicer-LICENSE.txt`.
- **CT treatment:** Actual axial slice changes captured from the viewer. The source volume is 360 × 360 × 330, with 0.5 mm spacing. Film shots are screen-display derivatives.
- **Surface treatment:** A nonclinical display derivative of the same sample, produced with marching cubes using every third source voxel and a threshold of 650 in stored values. No smoothing, registration, tooth identification, or validated segmentation. The film shows actual rotation of this uploaded model in the app. It is not an iTero export and is not a scan of the fictional patient. Source orientation is unverified.

The sample providers and equipment vendors do not endorse Harmony. Vendor names identify the demonstrated workflow and intended file sources.

## Production

Both editions include synthetic narration and on-screen feature captions, without music. Harmony’s Spectral and Hanken typefaces and forest/ivory palette are used in the edit. Animated framing, transitions, a mobile frame, and the PDF close-up were composed from captured product screens. Public samples remain labeled in the film.

## Expanded system tour

The 3:11 tour adds captured patient history, tooth-level records, search, source reports, a supplied synthetic report import, treatment planning, pharmacy links, coronal and sagittal CT views, file intake, and simulated aftercare scheduling and callback review. No external calls or messages were made. Private patient-link URLs were excluded from the film.

## Voiceover

Narration was generated locally with the standard `af_heart` voice using [Kokoro-ONNX](https://github.com/thewh1teagle/kokoro-onnx) and [Kokoro-82M](https://huggingface.co/hexgrad/Kokoro-82M). No real person’s voice was cloned. The scripts were written for the captured demonstrations; clips were timed by chapter and normalized for consistent playback. The model is Apache 2.0 licensed and the inference package is MIT licensed. Speech is encoded as AAC at 48 kHz. The original feature captions remain visible, with optional verbatim narration subtitles.
