## Runway's full-quality model

Runway 4.5 is Runway's flagship video generation model, built on a Transformer-based architecture that prioritizes spatial coherence, subject consistency, and cinematographic control. Where [Runway Gen 4 Turbo](/ai-models/video/runway-gen-4-turbo) is optimized for speed, Runway 4.5 delivers maximum quality — finer detail, more stable motion, and stronger adherence to complex camera and subject instructions.

The model handles both text-to-video and image-to-video workflows, with standout performance on controlled camera movements, consistent character behavior across a clip, and physically accurate scene composition.

## Capabilities

<CardGroup cols={3}>
  <Card title="Precise camera control" icon="video">
    Responsive to cinematographic prompts — dolly shots, pans, tilts, tracking shots, and static frames all render reliably with the specified movement.
  </Card>

  <Card title="Subject consistency" icon="user">
    Maintains consistent appearance of characters and objects throughout a clip, reducing drift or morphing common in earlier video models.
  </Card>

  <Card title="Text-to-video" icon="text">
    Generates high-quality video directly from detailed text prompts, with strong spatial and narrative coherence.
  </Card>

  <Card title="Image-to-video" icon="image">
    Animates a static reference image with specified motion, lighting changes, or camera movement.
  </Card>

  <Card title="Multiple aspect ratios" icon="expand">
    Supports 16:9, 9:16, 1:1, 4:3, 3:4, and 21:9 for flexible delivery across platforms and formats.
  </Card>

  <Card title="Cinematic motion quality" icon="film">
    Transformer architecture delivers smooth, physically plausible motion — natural inertia, realistic object interaction, and stable scene composition.

## Prompting tips

* **Use camera terms precisely** — "Slow dolly forward," "handheld close-up tracking the subject," and "static wide shot with subtle camera shake" all produce reliably different cinematic results.
* **Describe subject behavior** — "A woman slowly turns to face the camera," "a car accelerates from a standstill" — specific actions translate to consistent motion.
* **Specify lighting** — "Soft diffused window light," "high-contrast backlit silhouette," or "golden hour side lighting" guide the visual mood.
* **Image-to-video: match your prompt to your image** — The reference image anchors the scene; the prompt should describe the motion and changes, not restate what's already visible.

### Example prompts

> A lone astronaut stands on the surface of Mars, slowly turning to survey a vast red canyon. Cinematic wide shot, dust particles catching the sunlight, no sound. 24 FPS.

> Close-up on a steaming cup of coffee being placed on a marble table. Slow-motion, soft natural window light, shallow depth of field, bokeh background.

<Tip>
  For fast iterations and drafts, use [Runway Gen 4 Turbo](/ai-models/video/runway-gen-4-turbo). Switch to Runway 4.5 for final-quality renders where the extra generation time is worth the result.
