A prompt to start from
Use Strata. Create an eight-second Strata Levels example with a tall crop of the workshop footage occupying the left 1216 px and a quiet Bone editorial panel on the right. Set three large Exposure lines “Light.” “Shade.” “Balance.” and small Denim branding. Leave the opening untreated, then ease Levels input black to 10, input white to 240 and gamma to 1.18 between 1.2 and 3.6 seconds. Keep output endpoints at 0 and 255. Preserve moving footage, neutral type, ample spacing and editable controls.
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.
