Features

ThinkSound

ThinkSound is a cutting-edge video-to-audio generation model that creates realistic sound effects and audio tracks from video content. By analyzing the visual elements and actions in your video, it generates high-quality audio that perfectly matches what’s happening on screen.

Why It Stands Out

• Video-to-audio generation: Converts video content into corresponding audio tracks automatically.
• Context-aware sound: Analyzes visual elements and actions to generate matching audio.
• Prompt-guided output: Add text descriptions to guide the style and type of audio generated.
• Prompt Enhancer: Built-in AI-powered prompt optimization for better audio results.
• High-quality output: Produces clear, realistic audio that enhances the multimedia experience.
• Reproducibility: Use the seed parameter to recreate exact results or explore variations.

Parameters

How to Use

1. Upload your video — drag and drop a file or paste a public URL.
2. Add a prompt (optional) — describe the type of sound you want. Use the Prompt Enhancer for AI-assisted optimization.
3. Set a seed (optional) for reproducible results.
4. Click Run and wait for audio generation.
5. Preview and download the result.

Best Use Cases

• Video Post-Production — Add sound effects to silent footage or animations.
• Content Creation — Generate audio tracks for social media videos and clips.
• Game Development — Create sound effects for gameplay footage and trailers.
• Film & Animation — Produce foley and ambient sounds for scenes.
• Advertising — Add impactful audio to promotional videos.

Pro Tips for Best Quality

• Use videos with clear visuals and distinct actions for best audio matching.
• Add prompts to specify the type of sound you want (e.g., “engine roaring”, “footsteps on gravel”).
• Ensure the video has visible sound-producing elements like movement, impacts, or environmental features.
• For complex scenes, describe the primary sound you want the model to focus on.
• Fix the seed when iterating to compare different prompt variations.

Notes

• Ensure uploaded video URLs are publicly accessible.
• Processing time varies based on video length and current queue load.
• Please ensure your content complies with usage guidelines.
