You don't need
a video editor.
HyperFrames renders the
HTML you already
write into pixel-perfect,
deterministic video.
```
Copy npx hyperframes add streaming-text to the clipboard
That writes one file: `compositions/components/streaming-text.html`.
## Paste it into your composition
Open `compositions/components/streaming-text.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.
## Variables
Every one of these has a default, so the piece works untouched. Set the ones you
want to change on the element:
| Variable | Default | Accepts | What it does |
| - | - | - | - |
| `size` | `27` | 18px to 64px, step 1px | Type size of the streamed words. |
| `tone` | `dark-on-light` | `dark-on-light`, `light-on-dark` | Ink pair: dark words on a light ground, or light words on a dark ground. |
Set them with `data-variable-values` on the element that mounts it. These are the
defaults, so this behaves exactly like the preview above until you change one:
```html wrap theme={null}
