Bézier point handles.

Shape the curvature entering or leaving a point.

Change curvature by moving Bézier handles while keeping anchor endpoints fixed. cubic control points pull a straight Sea path into a wave, with aligned tangent lines showing their direction. The path, control points and separate before/after geometry remain editable.

Try it in your agent.

A prompt to start from

Use Strata. Create an eight-second silent Strata Bézier study on Bone. Set “Shape the flow.” across the upper-left area. A broad Sea curve spans the lower canvas. Keep its two anchor endpoints fixed while its outgoing and incoming cubic handles separate vertically, turning a straight path into a relaxed wave. Show thin tangent lines and small Sunset handle dots, all aligned with the actual cubic control points. Retain editable before/after path geometry; do not substitute a hand-drawn motion overlay for the cubic edit.

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?
