npx hyperframes add caption-blend-difference
```

## Paste it into your composition

Open `compositions/components/caption-blend-difference.html` and copy what is inside into your own composition.
The file opens with a comment header that walks you through it.

A component has no size or duration of its own. It takes both from the composition
you paste it into.

Tagged `text` `text-effect` `effect` `blend-mode` `contrast` `inversion`.
