Seedance Models - The Essentials

Seedance is ByteDance’s premier AI video generation suite, engineered to create cinematic, high-fidelity content from text and images. The 1.0 series established a standard for fluid motion and multi-shot consistency, while the 1.5 series (Dec 2025) introduces native audio-visual (AV) synchronization and professional directorial controls.


1. Seedance Models Overview

The Seedance lineup consists of two generations:

  • Seedance 1.5 Pro (Dec 2025): A native Audio-Visual (AV) model. It generates pixels and audio simultaneously for perfect synchronization. Features 1080p output, multilingual lip-sync, and advanced directorial camera controls

  • Seedance 1.0 Pro: Tailored for production-quality clips, it delivers full 1080p resolution and advanced cinematic features.

  • Seedance 1.0 Pro Fast: A faster and cheaper version of Seedance 1.0 Pro

  • Seedance 1.0 Lite: Optimized for speed and iteration, this version outputs videos in 720p or 1080p resolution.


2. Key Strengths

Native Audio-Visual (AV) Synthesis

Seedance 1.5 generates audio and video in a single pass. This ensures environmental sounds (e.g., footsteps, glass breaking) and speech are perfectly timed to the on-screen action, eliminating the need for audio post-production.


Multilingual Lip-Sync & Expression

The 1.5 model supports precise dialogue in English, Mandarin, Spanish, Japanese, Korean, and even regional Chinese dialects (Sichuan/Shaanxi). It captures subtle micro-expressions and non-verbal cues like sighs, laughter, or "sobbing" tones.


Advanced Directorial Control

The models understand technical film grammar. Creators can invoke specific descriptions like:

  • “Dolly Zoom on the subject” (The Hitchcock effect).

  • “Long-take tracking shot following the character.”

  • “Whip pan transition to reveal the skyline.”


Native Multi-Shot Storytelling

Seedance performs well in generating videos with multiple cohesive shots, maintaining consistency in subjects, visual style, and atmosphere across transitions. This capability enables creators to produce narrative videos with seamless changes between different shots, enhancing storytelling.

Especially in 1.0 Pro, you can invoke cinematic descriptions, such as: “Drone fly-through of a snowy canyon”, “Tracking shot circling around a samurai” or “Close-up with shallow depth of field”. Use Prompt Spark to enrich those guidelines and get the best out of Seedance!


Diverse Stylistic Expression

Seedance 1.0 generates high-quality videos across different styles like realism, animation, advertising... It interprets cinematic descriptors embedded in prompts (e.g., “shot on 35mm film”, “cinematic noir lighting”), enabling creators to guide lighting and composition. This responsiveness allows for exploration across a wide range of visual directions, with the Pro version particularly attuned to film genres, and specific visual references.


Enhanced Motion Generation

Seedance shows great results generating fluid and intentional motion. Pro-version outputs feel “directed,” rather than stitched together. For instance, camera pans accelerate and decelerate naturally, and character motion reflects believable physical forces.

The model ensures natural motions for scenes and subjects, offering stable structures, camera control, and minimal distortion. Whether it's a skier gliding down a slope or a model walking on a runway, Seedance 1.0 captures motion with remarkable fidelity.


3. Parameters

Resolution and Duration

  • Seedance 1.5 Pro: Native 1080p; 5–12 seconds duration.

  • Seedance 1.0 Suite: 480p, 720p, or 1080p; 2–12 seconds duration.

  • Frame Rate: ~24–30 fps across all models to preserve cinematic fluidity.

  • All versions support a variety of aspect ratios, including 16:9, 4:3, 1:1, 3:4, 9:16, 21:9, and 9:21.


Input Modalities

  • Text-to-Video: Fully supported; 1.5 offers superior semantic interpretation of dialogue and sound.

  • Image-to-Video: Uses the "First Frame" to lock character identity and lighting.

  • First & Last Frame Control: Available in both 1.0 and 1.5 for precise beginning and end-point transitions.


4. Use Cases & Examples

Seedance is well-suited for creators seeking cinematic visuals and realistic motion in their video content. Key applications include:

Cinematic Shorts & Previsualization

Seedance Pro enables the transformation of static concepts into dynamic video clips, ideal for cinematic shorts and scene previsualization. The process begins with a carefully selected or generated base image that establishes the setting, characters, and visual tone. From there, a detailed prompt is written to describe the desired action, including camera movement, environmental effects, and element interactions. The model interprets this input to generate realistic animations with cinematic lighting and fluid motion. This workflow is perfect for testing visual ideas, building animated storyboards, and supporting larger productions. It saves time during concept development and provides a clear preview of the final visual direction.


Moodboards & Style Exploration

This workflow helps creators develop moodboards and explore visual styles quickly and effectively. The process starts with defining a set of reference characters, objects, or scenes and placing them against distinct backgrounds or color palettes to emphasize aesthetic variation. Detailed prompts describe subtle movements, expressions, or gestures to bring life to each element, adding personality and energy. This approach enables rapid testing of different design directions, helping teams align on tone, genre, and style for marketing campaigns, branding, or creative projects while maintaining a cohesive visual language.


Music Video Concepts

This workflow allows creators to design visually striking music video concepts by combining choreography, dynamic lighting, and cinematic camera movements. In this example, the process uses text-to-video to generate a full scene from a detailed prompt. The prompt defines the dancers, their outfits, and the environment, such as neon-lit stages or futuristic sets. Subtle descriptions of synchronized dance routines, camera paths, and mood lighting bring energy and rhythm to the scene. This approach is ideal for experimenting with creative ideas, previsualizing dance sequences, and building high-impact visuals for artists and production teams looking to refine their concepts before full-scale production.


Character-Focused Sequences

Creators can animate subjects with consistent identities and expressive motions using image-to-video. The process begins with a strong character design captured in a still image, then expands through prompts that describe emotional reactions, body language, and interactions with the environment. These animations preserve visual fidelity and personality across multiple shots, making it possible to craft dramatic scenes, dynamic chases, or subtle emotional beats. This approach is perfect for testing character-driven storytelling, previsualizing key narrative moments, and refining animation concepts for games or cinematic productions.


Product Demonstrations

In Product Demonstrations, the process involves transforming static product visuals into dynamic, cinematic presentations that showcase details and design features. Starting from a high-quality image of the product or environment, Seedance applies smooth camera movements like slow orbits and glides to highlight key angles and textures. Subtle motion effects, lighting adjustments, and environmental elements such as reflections or floating particles enhance realism and elegance. This approach creates engaging sequences for marketing, presentations, and social media, ideal for luxury items, interior spaces, and tech products.


5. Conclusion

Seedance 1.5 marks the shift from a visual generator to a complete Audio-Visual production engine. By unifying 1080p cinematic motion with native sound, it bridges a gap between AI experimentation and professional-grade video workflows.
