Seedance 1.5 Pro Video Generation Demo

What Is Seedance 1.5 Pro

Seedance 1.5 Pro is an advanced AI video model developed by ByteDance for native audio-visual generation. It creates video and audio together in a single process, allowing motion, speech, and sound to stay precisely aligned. The model supports dialogue-driven scenes, cinematic camera movement, and coherent multi-shot storytelling. By reducing sync issues and manual post-processing, Seedance 1.5 Pro helps creators and teams produce realistic, story-focused videos with greater stability, speed, and creative control.

Key Features of Seedance 1.5 Pro

Seedance 1.5 Pro combines native audio-visual generation with flexible resolution, duration, and frame control for professional video creation.

Text-to-Audio-Visual Generation

Seedance 1.5 Pro generates synchronized video and audio from text prompts, supporting 480P and 720P output. Creators can produce clips from 4 to 12 seconds at 24fps, achieving smooth motion and natural sound alignment.

First-Frame Image-Guided Audio-Visual Control

By setting a starting frame, creators can define style, composition, and character appearance. The model generates fluid motion and synced audio at up to 720P, maintaining visual consistency across 4–12s sequences.

Start-to-End Frame Controlled Generation

Seedance 1.5 Pro allows creators to specify both the first and last frames of a video. This enables precise control over narrative flow while producing stable 24fps audio-visual output within a 4–12 second duration.

Native Audio-Visual Synchronization

Audio and visuals are generated together in a single process, ensuring accurate lip sync, timing, and emotional rhythm. This unified pipeline produces smooth 24fps videos with coherent sound and motion.

Multi-Shot Narrative Continuity

Across multiple shots, Seedance 1.5 Pro maintains consistent characters and scenes while supporting short cinematic sequences from 4 to 12 seconds. This makes structured storytelling possible even in compact video formats.

Core Advantages of Seedance 1.5 Pro

Seedance 1.5 Pro delivers tightly synchronized audio-visual generation, realistic dialogue, and cinematic storytelling in a single, controllable workflow.

High-Precision Audio-Visual Synchronization

Seedance 1.5 Pro natively generates audio and visuals together, including voice, background music, ambient sound, and action effects. All elements are aligned at millisecond level for consistent timing and realism.

Multi-Character and Multilingual Dialogue

The model supports monologues and multi-character conversations with precise lip-sync. It covers Mandarin, regional dialects, English, and other languages, delivering natural pacing and authentic conversational texture.

Cinematic Narrative Tension

With natural motion range and strong rhythm control, Seedance 1.5 Pro captures fine-grained actions, facial expressions, and emotional shifts. This results in vivid scenes with film-level narrative impact.

Built-In Visual Effects and Creative Styles

Seedance 1.5 Pro includes native support for multiple visual effects and style templates. Creators can trigger effects directly through prompts, making it especially effective for animation, stylized stories, and creative experiments.

Storytelling & Emotional Expression

Auto-fill narrative beats and keep emotions, expressions, and actions cohesive across shots.

Film-Grade Cinematography & Visual Quality

Smooth camera moves, strong composition, and rich atmosphere—close-up to wide shot.

Core Technical Breakthroughs in Seedance 1.5 Pro

Seedance 1.5 Pro introduces native audio-visual modeling and a unified generation architecture to improve realism, stability, and production efficiency.

Native Audio-Visual Joint Generation

Seedance 1.5 Pro generates video and audio within a single unified process rather than separate stages. This design improves lip-sync accuracy, timing alignment, and rhythm consistency, reducing post-processing and synchronization errors.

Unified Multimodal Generation Architecture

The model uses a unified multimodal architecture that allows audio and visual signals to interact during generation. This strengthens temporal alignment and semantic consistency across scenes and different input tasks.

High-Quality Audio-Visual Data Framework

Seedance 1.5 Pro is trained on curated audio-visual datasets that emphasize motion clarity, sound realism, and visual aesthetics. Rich annotations help the model better understand scene context and intent.

Optimized Training and Inference Pipeline

Through supervised fine-tuning, audio-visual RLHF, and inference acceleration, the model achieves faster generation while maintaining stable quality, supporting real-world production workflows.

Professional Use Cases with Seedance 1.5 Pro

Seedance 1.5 Pro supports professional audio-visual creation across narrative, commercial, and experimental workflows.

Film, Animation, and Digital Storytelling

Seedance 1.5 Pro enables film and animation creators to produce complete audio-visual clips in minutes. Native sound and motion generation reduce post-production work while supporting expressive characters and cinematic storytelling.

Advertising and Brand Campaigns

For advertising teams, Seedance 1.5 Pro shortens production cycles and lowers costs. Finished videos with synced voice, music, and visuals can be delivered quickly, making campaigns more agile and scalable

Short Dramas and Online Series

The model supports dialogue-driven scenes and multi-character interactions, allowing rapid creation of short episodes. Minute-level generation helps teams iterate faster and respond to audience feedback.

Marketing Content and Social Media Videos
