Feature Comparison

Seedance 2 AI Video Generator

Multimodal Input Generation

Seedance 2.0 supports three distinct generation modes: Text-to-Video, Image-to-Video, and Video-to-Video. This multimodal flexibility allows users to initiate creation from a written concept, a visual reference image to maintain style consistency, or existing source footage for controllable restyling and motion transfer. Each mode is optimized for specific workflows, providing maximum creative flexibility whether you are concepting from scratch or iterating on established visual material.

Reference-First Workflow for Consistency

A key technical differentiator is its reference-first generation approach. By using an image or video clip as a reference input, the model anchors the output's character design, artistic style, color palette, and camera perspective. This significantly reduces the guesswork and iterative prompting often required in AI video generation, leading to more predictable, coherent, and brand-consistent results essential for professional projects and serialized content.

Joint Audio-Video Synthesis

The platform features advanced joint audio-video synthesis in a single generation pass. This includes synchronized audio generation encompassing sound effects (SFX), background music scoring, and voice dialogue. Critically, it supports accurate lip-sync for over ten languages, including English, Chinese, Japanese, and Korean. This integrated feature streamlines post-production by delivering a complete audiovisual package, eliminating the need for separate audio editing and syncing steps.

High-Fidelity Output Specifications

Seedance 2.0 delivers professional-grade output specifications. It generates videos up to 1080p resolution at a cinema-standard frame rate of up to 24fps for smooth playback. Videos can be created in durations of 5 to 10 seconds per generation, with extension capabilities, and in aspect ratios of 16:9, 9:16, and 1:1 for optimal display across social platforms, widescreen formats, and mobile screens. All output is delivered in the universally compatible MP4 (H.264) format.

Concept Visualization and Storyboarding

Filmmakers, ad agencies, and creative directors can use the Text-to-Video and Image-to-Video modes to visualize concepts and create dynamic storyboards.
