## The fastest AI video generation available

xAI's Grok Video is built on Aurora — an autoregressive architecture that predicts video frames sequentially rather than through the diffusion process used by most other models. This fundamental difference is what enables Aurora's \~17-second generation time, making it the fastest AI video model available on ImagineArt by a significant margin.

Despite the speed advantage, Grok Video delivers native audio (background music, sound effects, and ambient audio synchronized with the video), identity preservation with up to 7 reference images, and smooth natural motion. The reference-to-video mode is particularly strong: character identity, style, and visual consistency are preserved across the generation with minimal drift.

## How to use

<Steps>
  <Step title="Open the AI Video Generator">
    Log into ImagineArt and go to the **AI Video Generator**.
  </Step>

  <Step title="Select xAI Grok Video">
    Choose **xAI Grok Video** from the model dropdown.
  </Step>

  <Step title="Choose your generation mode">
    Select text-to-video, image-to-video, or reference-to-video.
  </Step>

  <Step title="Upload references (optional)">
    For reference-to-video, upload up to 7 reference images to anchor identity and visual style.
  </Step>

  <Step title="Write your prompt">
    Describe the scene, motion, and audio environment. Include sound cues explicitly for the audio generation.
  </Step>

  <Step title="Generate">
    Click **Generate** — expect results in approximately 17 seconds.
  </Step>
</Steps>

## Prompting tips

* **Use it for rapid iteration** — 17-second generation means you can test 10–15 variations in the time it takes other models to produce 2 or 3. Explore directions aggressively before committing.
* **Audio cues work naturally** — "With upbeat jazz playing in the background" or "the sound of waves crashing" integrate naturally into Grok Video's audio generation.
* **Reference-to-video for consistent characters** — Upload multiple reference angles of a character (front, side, 3/4 view) to improve identity consistency across different generated scenes.
* **Keep prompts focused** — Aurora's sequential architecture produces the most coherent motion when the prompt describes a single, clear visual sequence rather than a complex multi-event narrative.

### Example prompts

> A golden retriever puppy plays in a field of daisies, tail wagging. Upbeat acoustic guitar music. Bright afternoon sunlight, slow motion on the playful moments. 6 seconds, 16:9.

> A barista writes a customer's name on a coffee cup with a marker. Soft café ambient sounds, quiet chatter in background. Close-up, handheld feel. 6 seconds.

| [Runway Gen 4 Turbo](/ai-models/video/runway-gen-4-turbo) | \~30s     | No    | —           | Fast cinematic, no audio |
| [Seedance Pro Fast](/ai-models/video/seedance-pro-fast)   | Under 60s | No    | Image input | Fast Seedance quality    |
| [PixVerse v5](/ai-models/video/pixverse-v5)               | \~30s     | No    | —           | Fast character animation |

<Tip>
  xAI Grok Video is the right choice when generation speed is a priority — especially for clients needing fast previews, high-volume production pipelines, or exploratory rapid iteration with audio. For maximum resolution or longer clips, other models in the lineup offer higher output specifications.
