Reveal footage through an editable shape.
Give a video a custom silhouette without baking it into the footage. Your agent can reshape the mask and animate the reveal while keeping the video layer intact.
Try it in your agent.
Use this prompt as a starting point. Review the result, then ask for the details you want to change.
A prompt to start from
Use Strata to reveal the supplied coastal clip through an asymmetric curved window. Keep a quiet area beside it for a headline. Animate the window from narrow to fully open, then hold while the footage continues moving. Use an editable vector mask, keep the original video separate, and check that the person stays visible throughout.
Keep control of the result.
- Mask shape
- Edit the outline and its Bézier handles.
- Reveal timing
- Animate the mask’s geometry or transform over time.
- Source footage
- Replace or retime the clip separately from the mask.
A few useful details.
Does the mask modify the original footage?
No. The mask controls which parts of the video layer are visible. The source clip remains separate.
Can the mask move or change shape?
Yes. The vector outline and supported transforms can be animated, so the reveal can evolve over time.
How do I try this with my agent?
Copy the prompt into your supported local agent with Strata installed. Review the preview, then ask for the changes you want. The composition stays editable as you refine it.
Where does the video render?
Strata previews and renders locally on an Apple Silicon Mac. The local engine is free; your agent’s subscription or usage costs are separate.
