A prompt to start from
Use Tesseract. Create an eight-second silent Tesseract composition. On a Bone canvas, use the Exposure[-30] title “Let light / lead.” at left. Reveal a moving coastal film at right through a fully opaque black-to-white horizontal gradient using a Luma track matte: the dark side disappears into the canvas while the bright side preserves the person and sea. Keep the matte source separate and editable. Use continuous footage as the motion; the mask should have a stable, soft spatial reveal.
Tesseract plugins and runtime downloads are coming soon.
A few useful details.
How do I try this with my agent?
Tesseract plugins and runtime downloads are coming soon. Save the sample prompt for launch. Once Tesseract is installed, your local agent can use it to create, preview, and refine an editable project.
Where does the video render?
Tesseract previews and renders locally on a Mac. The local engine is free; your agent’s subscription or usage costs are separate.
