A prompt to start from
Use Strata. Create an eight-second silent Strata reveal with the packaged workshop footage. Use a Bone canvas, “Ease / into it.” in large neutral Exposure[-30] at left and a broad elliptical film window at right. Fade the window in by animating the mask opacity from 0.1 to 1 between 0.5 and 3.5 seconds. Keep the video layer’s own opacity at 100% and its geometry fixed. Hold the fully revealed moving footage. The editable animation must target the mask item’s opacity, not the layer or an overlaid rectangle.
A few useful details.
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.
