Introducing ByteDance Seedance 1.5 Pro Text-to-Video on WaveSpeedAI

The AI video generation landscape just took a major leap forward. WaveSpeedAI is excited to announce the availability of ByteDance Seedance 1.5 Pro (Text-to-Video)—a production-grade model that transforms text prompts into cinematic, live-action quality video clips with unprecedented realism and control.

Built by ByteDance’s Seed team, Seedance 1.5 Pro represents the next evolution in text-to-video generation, specifically engineered for professional workflows in advertising, short drama production, and creative content creation.

What is Seedance 1.5 Pro?

Seedance 1.5 Pro is ByteDance’s flagship text-to-video model designed from the ground up for cinematic realism, strong prompt adherence, and expressive motion. Unlike models that prioritize speed over quality, Seedance 1.5 Pro focuses on delivering production-ready output that rivals traditional video production.

The model leverages a sophisticated Diffusion Transformer architecture with 4.5 billion parameters, incorporating post-training optimizations through Supervised Fine-Tuning (SFT) on high-quality datasets and Reinforcement Learning from Human Feedback (RLHF). This technical foundation enables the model to understand complex scene descriptions, execute nuanced camera movements, and generate emotionally resonant performances.

What sets Seedance 1.5 Pro apart is its ability to understand the narrative intent behind your prompts. It doesn’t just generate pretty clips—it creates coherent moments with proper pacing, composition, and emotional beats that feel like they belong in a professionally produced piece.

Key Features

Cinematic Visual Quality

Seedance 1.5 Pro delivers a natural, live-action aesthetic with stable lighting, harmonious color grading, and professional-grade composition. The output looks like footage from a high-end production, not synthetic AI-generated content.

Superior Prompt Adherence

The model accurately interprets detailed scene descriptions, specific shot instructions, and emotional tone. Whether you’re describing a close-up of a character’s reaction or a sweeping establishing shot, Seedance 1.5 Pro executes your vision faithfully.

Expressive Motion and Emotion

From subtle facial expressions to dynamic action sequences, the model generates natural motion with strong rhythm. Fine-grained emotional delivery makes it ideal for drama-like performances and high-impact advertising content.

Flexible Duration Control

Generate clips anywhere from 4 to 12 seconds with precise integer control. The Smart Duration feature (-1) lets the model intelligently determine the optimal length based on your prompt’s narrative arc.

Multiple Aspect Ratios

Choose from six aspect ratio options: 16:9, 9:16, 4:3, 3:4, 1:1, and 21:9. The adaptive setting allows the model to automatically select the best ratio based on your content.

Reproducible Results

Seed-based generation ensures you can recreate results consistently—essential for iterative creative workflows where you need to refine specific elements while maintaining overall consistency.

Rich Visual Effects Through Prompting

Achieve a wide variety of visual effects directly through natural language prompts, from cinematic camera techniques like dolly zooms to stylistic treatments—no additional tools required.

Real-World Use Cases

Advertising and Marketing

Marketing teams can create professional promotional videos with product demonstrations, compelling narratives, and premium aesthetics. Seedance 1.5 Pro’s cinematic quality makes it ideal for luxury brands, product launches, and social media campaigns that demand high production value.

The model excels at generating emotion-forward content—those critical “hero moments” in advertisements where viewer connection matters most. Its ability to maintain stable visual quality across multiple generations also enables efficient A/B testing of different creative concepts.

Short Drama and Episodic Content

Content creators producing short dramas, web series, and story-driven social content will find Seedance 1.5 Pro invaluable. The model maintains character consistency, emotional continuity, and narrative coherence—moving beyond isolated clips toward structured storytelling.

Its understanding of cinematic language means it can execute proper shot compositions, pacing, and emotional beats that feel professionally directed rather than randomly generated.

Template-Based Creative Workflows

For agencies and production houses requiring rapid iteration, Seedance 1.5 Pro’s prompt-driven approach enables template-like creative effects. Teams can quickly experiment with different visual styles, camera movements, and narrative structures without lengthy production cycles.

Social Media Content at Scale

The combination of flexible duration control, multiple aspect ratios, and consistent quality makes Seedance 1.5 Pro perfect for creating platform-optimized content. Generate vertical content for TikTok and Instagram Reels, widescreen for YouTube, or square formats for feed posts—all from the same workflow.

Pro Tips for Best Results

• Keep prompts specific but focused: Limit the number of primary subjects and simultaneous actions, especially for shorter clips
• Use fixed camera for stability: If you notice shaky composition, enable fixed_camera and describe motion through subject movement rather than camera movement
• Write to a narrative endpoint: When using Smart Duration, include a clear “end beat” in your prompt so the model knows where to conclude naturally

The Future of Video Production

Seedance 1.5 Pro represents a significant milestone in AI video generation—where quality, control, and accessibility converge. It’s no longer about choosing between speed and production value; you can have both.

For creative professionals, marketing teams, and content creators, this means dramatically accelerated workflows without compromising on the cinematic quality your audiences expect. For businesses, it means professional video content is now accessible at a fraction of traditional production costs.
