Blur In
Each word resolves out of a soft blur the moment it is spoken, for captions that arrive quietly
Installation
$ pnpm dlx shadcn@latest add @remocn/caption-blur-inUsage
CaptionBlurIn takes a timed transcript and renders only the text block, so
place it inside your own AbsoluteFill. Every word stays hidden until its own
start time, then resolves from a blur into sharp focus while it fades up. The
space for the whole phrase is reserved from the first word, so the line never
reflows as it builds. See Positioning
for safe placements and Get a transcript
for producing captions.json.

| Prop | Type | Default | Description |
|---|---|---|---|
captions | Caption[] | — | The timed transcript, in the `Caption` shape from `@remotion/captions`. Times are relative to the start of the surrounding `Sequence`. |
blur | number | 12 | Blur radius in pixels each word starts from before it comes into focus. |
combineTokensWithinMilliseconds | number | 1200 | How much speech one page may span before the next word starts a new page. Pages also break at the end of a sentence and on any pause of at least `holdMs` (300 ms minimum). |
holdMs | number | 600 | How long a page stays after its last word when the next page is not already due. It fades out at the end of the hold instead of hanging through the pause. |
fontSize | number | 64 | Font size in pixels. |
fontWeight | number | 800 | Font weight. The font itself is inherited. |
color | string | "#ffffff" | Text colour. |
shadow | boolean | true | A tight text shadow that keeps the caption legible over bright footage. |
className | string | — | Classes for the text block — width, font family, `uppercase`. |
