A prompt to start from
Use Strata. Create an eight-second silent Strata typographic film composition using the packaged workshop footage. On Bone, set “Type, with a story.” across the upper portion in neutral Exposure[-30]. Below it, use the large editable word “MAKE” as an alpha track-matte source for the moving workshop video, so the footage is visible only inside the letter shapes. Keep the matte as Text and the video continuous and fixed. No prerendered letters, clipping-path approximation or luma matte should replace the actual alpha-matte relationship. Use generous outer margins and keep the footer separate.
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.
