Person mattes.
Separate a person from the background for compositing.
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. Create an eight-second silent Strata person-isolation demo. Place “Stand / apart.” at left on Sky. At right, use the packaged speaking-creator footage to create a real Person Matte through the packaged RVM model, then use it as a Luma matte on an exactly aligned duplicate of that footage. Replace the room background with Sky and a large Sunset circle which expands gently behind the person. Preserve continuous movement and soft hair detail. Use actual segmentation rather than an illustrated silhouette.
A few useful details.
Does this isolate any object?
This workflow uses a supported person-segmentation model. It does not claim general object tracking or manual-quality rotoscoping.
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.
