Model Details

Veo 3.1 redefines video creation by allowing users to generate high-fidelity, 8-second videos that transition seamlessly between a specific starting image and an ending image. This "frame-specific generation" capability gives creators precise control over the video's trajectory, ensuring the output begins and resolves exactly as intended. Whether animating a character's movement, transforming a scene's lighting, or depicting a changing landscape, the model intelligently interpolates the frames between the two inputs based on a descriptive text prompt.

Beyond simple cross-fading, this model understands semantic context and physics, generating realistic motion and intermediate states that bridge the gap between the provided visuals. The result is a smooth, cinema-quality video available in 720p or 1080p resolutions, accompanied by natively generated audio that synchronizes with the visual events.

### Use Cases * **Storytelling:** Visualizing a character disappearing, a prop changing location, or a scene evolving over time. * **Creative Transitions:** Morphing one object into another or shifting between distinct environments (e.g., day to night). * **Marketing:** Creating dynamic transitions between product states, such as a box opening or a device turning on.

### How to get the best results * **Prompting:** Clearly describe the action, movement, or change occurring between the two frames in the `prompt` field (e.g., "The fog thickens and swirls around her, and she slowly fades away"). * **Image Alignment:** For the most cohesive results, ensure the first and last images share a consistent artistic style and aspect ratio. * **Configuration:** The model creates 8-second videos by default for this mode. Select between `16:9` or `9:16` aspect ratios to match your input images and target platform.

To run via ModelRunner javascript client, use the following code:

```javascript import { modelrunner } from "@modelrunner/client";

const result = await modelrunner.subscribe('google/veo-3.1-first-last-frame-to-video', { input: { "prompt": "The fog thickens and swirls around her, and she slowly fades away, vanishing completely.", "negative_prompt": "low quality, blurry, distorted, cartoon", "image_url": "https://storage.googleapis.com/generativeai-downloads/images/ghost_girl.png", "last_frame_url": "https://storage.googleapis.com/generativeai-downloads/images/empty_tree.png", "aspect_ratio": "16:9", "resolution": "720p" } }); ```
