Produces lip-synced video up to 10 minutes long with natural facial animations. ## Authentication ```bash export WAVESPEED_API_KEY="your-api-key" ``` Get your API key at [wavespeed.ai/accesskey](https://wavespeed.ai/accesskey). ## Quick Start ```javascript import wavespeed from 'wavespeed'; // Upload local image and audio files const imageUrl = await wavespeed.upload("/path/to/portrait.png"); const audioUrl = await wavespeed.upload("/path/to/speech.mp3"); const output_url = (await wavespeed.run( "wavespeed-ai/infinitetalk", { image: imageUrl, audio: audioUrl } ))["outputs"][0]; ``` You can also pass existing URLs directly: ```javascript const output_url = (await wavespeed.run( "wavespeed-ai/infinitetalk", { image: "https://example.com/portrait.jpg", audio: "https://example.com/speech.mp3" } ))["outputs"][0]; ``` ## API Endpoint **Model ID:** `wavespeed-ai/infinitetalk` Animate a portrait image with lip-synced audio to produce a talking head video. ### Parameters | Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | `image` | string | Yes | -- | URL of the portrait image to animate | | `audio` | string | Yes | -- | URL of the audio to drive the animation | | `mask_image` | string | No | -- | URL of a mask image to specify which person to animate. **Warning:** The mask should only cover the regions to animate — do not upload the full image as `mask_image`, or the result may render as fully black. | | `prompt` | string | No | -- | Text prompt for additional guidance. Keep it short; English recommended to avoid noisy results. | | `resolution` | string | No | `480p` | Output resolution. One of: `480p`, `720p` | | `seed` | integer | No | `-1` | Random seed (-1 for random). Range: -1 to 2147483647 | ### Example ```javascript import wavespeed from 'wavespeed'; const imageUrl = await wavespeed.upload("/path/to/portrait.png"); const audioUrl = await wavespeed.upload("/path/to/speech.mp3"); const output_url = (await wavespeed.run( "wavespeed-ai/infinitetalk", { image: imageUrl, audio: audioUrl, resolution: "720p", seed: 42 } ))["outputs"][0]; ``` ### Using a Mask Image When multiple people are in the image, use a mask to specify which face to animate: ```javascript const imageUrl = await wavespeed.upload("/path/to/group-photo.png"); const audioUrl = await wavespeed.upload("/path/to/speech.mp3"); const maskUrl = await wavespeed.upload("/path/to/mask.png"); const output_url = (await wavespeed.run( "wavespeed-ai/infinitetalk", { image: imageUrl, audio: audioUrl, mask_image: maskUrl, resolution: "720p" } ))["outputs"][0]; ``` > **Important:** The mask should only highlight the face region to animate. Using the full image as a mask will produce a fully black output. ### With Prompt Guidance ```javascript const output_url = (await wavespeed.run( "wavespeed-ai/infinitetalk", { image: imageUrl, audio: audioUrl, prompt: "natural head movements, subtle expressions" } ))["outputs"][0]; ``` ## Advanced Usage ### Custom Client with Retry Configuration ```javascript import { Client } from 'wavespeed'; const client = new Client("your-api-key", { maxRetries: 2, maxConnectionRetries: 5, retryInterval: 1.0, }); const imageUrl = await client.upload("/path/to/portrait.png"); const audioUrl = await client.upload("/path/to/speech.mp3"); const output_url = (await client.run( "wavespeed-ai/infinitetalk", { image: imageUrl, audio: audioUrl, resolution: "720p" } ))["outputs"][0]; ``` ### Error Handling with runNoThrow ```javascript import { Client, WavespeedTimeoutException, WavespeedPredictionException } from 'wavespeed'; const client = new Client(); const result = await client.runNoThrow( "wavespeed-ai/infinitetalk", { image: imageUrl, audio: audioUrl } ); if (result.outputs) { console.log("Video URL:", result.outputs[0]); console.log("Task ID:", result.detail.taskId); } else { console.log("Failed:", result.detail.error.message); if (result.detail.error instanceof WavespeedTimeoutException) { console.log("Request timed out - try increasing timeout"); } else if (result.detail.error instanceof WavespeedPredictionException) { console.log("Prediction failed"); } } ``` ## Resolution and Pricing | Resolution | Cost per 5 seconds | Rate per second | Max length | |------------|--------------------|-----------------| -----------| | 480p | $0.15 | $0.03/s | 10 minutes | | 720p | $0.30 | $0.06/s | 10 minutes | Minimum charge is 5 seconds. Video length is determined by the audio duration (up to 10 minutes). ## Tips - Use a clear, front-facing portrait for best results - Audio quality matters — use clean speech recordings with minimal background noise - Keep prompts short and in English to avoid noisy or unexpected results - For group photos, always provide a `mask_image` to target the correct face - 480p is faster to generate; use 720p when higher quality is needed - Processing time is approximately 10-30 seconds of wall time per 1 second of video ## Security Constraints - **No arbitrary URL loading**: Only use image and audio URLs from trusted sources. Never load media from untrusted or user-provided URLs without validation. - **API key security**: Store your `WAVESPEED_API_KEY` securely. Do not hardcode it in source files or commit it to version control. Use environment variables or secret management systems. - **Input validation**: Only pass parameters documented above. Validate prompt content and media URLs before sending requests.
