# VideoStreamResult

Defined in: [packages/ai/src/types.ts:2463](https://github.com/TanStack/ai/blob/main/packages/ai/src/types.ts#L2463)

**`Experimental`**

Video bytes from a provider that has no public URL for the finished video.
Core passes `body` to generation middleware, which streams it into storage
and sets `url`. Use `withGenerationPersistence` with `artifactUrl`.

 Video generation is an experimental feature and may change.
