Introducing Seedance 1.5 Pro Fast Image-to-Video on WaveSpeedAI
The way we transform static images into dynamic video content is evolving rapidly. Today, we’re excited to announce the availability of ByteDance Seedance 1.5 Pro Fast Image-to-Video on WaveSpeedAI—a powerful model that converts your still images into cinematic, production-ready video clips with unprecedented speed and quality.
Whether you’re creating ad content, social media shorts, or short-drama sequences, this model delivers the visual fidelity and motion control that professional workflows demand.
What is Seedance 1.5 Pro Fast Image-to-Video?
Seedance 1.5 Pro Fast Image-to-Video is ByteDance’s latest advancement in AI video generation technology. Built on the Dual-Branch Diffusion Transformer (DB-DiT) architecture with 4.5 billion parameters, this model takes a single reference image—plus an optional text prompt—and generates smooth, cinematic video clips ranging from 4 to 12 seconds.
What sets this model apart from its predecessors is the significant leap in both quality and capability. While Seedance 1.0 focused on establishing a stable foundation for motion generation, version 1.5 Pro pushes the boundaries of what’s possible. The model now features native joint audio-video generation, meaning it can produce synchronized sound alongside your video in a single pass—no separate dubbing step required.
The “Fast” variant is specifically optimized for rapid iteration, allowing creators to explore ideas quickly without sacrificing the core qualities that make Seedance exceptional: subject consistency, coherent motion, and that distinctive live-action aesthetic.
Key Features
First-Frame Fidelity
Your input image becomes the foundation of the video. The model preserves subject identity, lighting conditions, and compositional elements with remarkable accuracy, ensuring the generated video feels like a natural extension of your original vision.
Precise Motion Control
Guide exactly how your scene comes to life through detailed text prompts. Describe what moves, how it moves, and the intensity—from subtle ambient motion to dynamic action sequences.
Flexible Camera Behavior
Control your virtual camera with professional precision. Whether you need a locked-off tripod shot, a slow dolly-in, a sweeping orbit, or handheld documentary feel, the model responds accurately to your directorial intent.
Adaptive Aspect Ratios
Support for multiple aspect ratios (21:9, 16:9, 4:3, 1:1, 3:4, 9:16) means you can optimize for any platform—vertical for TikTok and Instagram Reels, widescreen for YouTube, or cinematic ultrawide for film projects.
Native Audio Generation
Toggle audio generation on or off based on your needs. When enabled, the model creates synchronized sound—including ambient audio, action sounds, and background elements—with millisecond-level precision.
Seed-Based Reproducibility
Lock your random seed to compare prompt variations fairly. This feature is invaluable for iterative refinement, letting you isolate exactly what changes when you adjust your prompts.
Resolution Options
Choose between 720p for rapid drafts and iteration, or 1080p for final production output.
Real-World Use Cases
Advertising and Commercial Content
Transform product photography into engaging video ads. A static shot of a luxury watch can become a cinematic reveal with ambient light play and subtle motion. Fashion brands can animate lookbook images into dynamic content that captures attention in crowded social feeds.
Social Media Short-Form Content
Content creators can multiply their output by animating key frames into scroll-stopping video clips. The model’s support for vertical aspect ratios and short durations (4-12 seconds) aligns perfectly with platform requirements for TikTok, Instagram Reels, and YouTube Shorts.
Short Drama and Narrative Content
Filmmakers and storytellers can use reference images to establish visual consistency across scenes. The model’s ability to preserve subject identity makes it ideal for creating character-driven content where maintaining visual continuity matters.
Game Cinematics and Concept Visualization
Game developers and concept artists can bring static artwork to life, visualizing how environments and characters might move before committing to full production. The model’s responsiveness to camera direction prompts enables rapid exploration of different cinematographic approaches.
E-commerce Product Showcases
Online retailers can transform product photography into dynamic presentations—rotating products, demonstrating features in motion, or creating lifestyle contexts that static images cannot achieve.
Getting Started on WaveSpeedAI
Using Seedance 1.5 Pro Fast Image-to-Video on WaveSpeedAI is straightforward:
-
Upload your image — Start with a well-composed reference image. Clean subjects and strong compositions yield the best results.
-
Write your prompt — Describe the shot as a single directive: what moves, how it moves, and the overall aesthetic. Structure it as subject/setting, motion, camera behavior, and visual style.
-
Configure your settings — Select your aspect ratio, duration (start short for iteration), and resolution. Enable audio if you want synchronized sound.
-
Generate and iterate — Use fixed seeds to compare prompt refinements, then vary the seed once you’ve locked in your direction.
Example prompt:
Futuristic orbital living room interior. Soft sunlight, vast luminous planet outside the panoramic window. Slow dolly-in, subtle floating dust, gentle parallax, cinematic color grade, calm mood.
