Bytedance Waver 1.0 API Documentation

Playground

Waver 1.0 is an all-in-one model for text-to-video, image-to-video, and text-to-image generation. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

Waver 1.0 is a powerful image-to-video generation model that transforms static images into dynamic, cinematic videos. Simply provide an image and describe the motion you want — the model brings your visual to life with smooth, high-quality animation.

Why It Stands Out

• Image-driven generation: Start from any image and animate it into a coherent video while preserving the original style and composition.
• Prompt-guided motion: Describe camera movements, actions, and atmospheric effects to control how your image comes to life.
• Prompt Enhancer: Built-in AI-powered prompt optimization helps craft better descriptions for improved results.
• High-quality output: Produces smooth, cinematic videos with natural motion and visual fidelity.
• Reproducibility: Use the seed parameter to recreate exact results or explore variations.

Parameters

How to Use

1. Upload your source image — drag and drop a file or paste a public URL.
2. Write a prompt describing the motion, camera movement, and atmosphere you want. Use the Prompt Enhancer for AI-assisted optimization.
3. Set a seed (optional) for reproducible results.
4. Click Run and wait for your video to generate.
5. Preview and download the result.

Best Use Cases

• Cinematic Content — Transform concept art and stills into dynamic movie-like sequences.
• Social Media Content — Turn photos into engaging video posts for TikTok, Reels, and Shorts.
• Marketing & Advertising — Animate product images and hero shots without expensive video production.
• Storytelling & Art — Bring illustrations, sci-fi scenes, and fantasy artwork to life.
• Game & Film Previews — Create animated concept trailers from static artwork.

Pricing

Pro Tips for Best Quality

• Use high-resolution, detailed source images for optimal results.
• Be specific in your prompt — describe camera movement (pan, zoom, tracking), subject actions, and environmental effects.
• Include atmospheric details like lighting changes, particle effects, or weather conditions.
• For sci-fi or fantasy scenes, describe volumetric effects like clouds, smoke, or energy.
• Fix the seed when iterating to compare different prompt variations.

Notes

• Ensure uploaded image URLs are publicly accessible.
• Processing time varies based on current queue load.
• Please ensure your prompts comply with content guidelines.
