Reproducible workflow · verified July 19, 2026
From four property photos to a reusable listing video
This is a synthetic demonstration, not a customer project or performance claim. The source property does not exist. We publish the inputs, output, settings, limitations, and SHA-256 checksums so the workflow can be inspected without trusting a highlight reel.
1. Input selection
The four views were generated as one coherent contact sheet with OpenAI image generation, then cropped into equal source images. The order follows a listing narrative: exterior, living room, kitchen, bedroom.
2. Generation and export
- Scene order
- 4 images × 7.5 seconds
- Motion
- Centered Ken Burns zoom, 1.00→1.08
- Output
- MP4/H.264, 1920×1080, 30 fps, 30.00 s
- Audio
- None, to keep the media rights and method explicit
3. Edit
Reorder source images, replace listing details, choose a motion preset, and preview before export. No claim is made that synthetic rooms represent an actual property.
4. Export
Use the browser workflow for an MP4 file. Confirm image permissions, property facts, contact details, and platform-safe music before publishing a real listing.
5. Reuse
Create aspect-ratio variants from the approved master, keep the source order and listing facts together, and archive the export with its input checksums.
Files, checksums, and limitations
The machine-readable record at metadata.json contains the final generation prompt, exact media settings, every SHA-256 checksum, and the toolchain disclosure. This test covers deterministic scene assembly and export; it does not measure lead conversion, property accuracy, or paid model quality.
