# kling-v3 - Text to Video

> Kuaishou's Kling 3.0 t2v model. Generate videos from text prompts with camera control, multi-shot storyboarding, and sound generation.

Kling 3.0 t2v is a text-to-video generation model from Kuaishou's Kling series, available through AnyFast API. Create videos from text descriptions with customizable camera movements, multi-shot storyboarding, and optional sound generation.

<Info>
  This page uses Kling's Legacy API: `POST /kling/v1/videos/text2video` with the `model_name` field. It does not use the upgraded `/text-to-video/kling-3.0` request structure.
</Info>

## Key capabilities

* **Text-to-Video** — Generate videos purely from text prompts
* **Camera Control** — Preset and custom camera movements (pan, tilt, zoom, roll)
* **Multi-Shot** — Create up to 6 storyboard shots with custom prompts and durations
* **Sound Generation** — Optionally generate synchronized sound or use up to 2 referenced voices
* **Multiple Output Modes** — `std` (720p), `pro` (1080p), and `4k`
