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.

Video Voiceovers

Content creators can use Bantr to generate high-quality voiceovers for videos, enhancing their productions with professional-sounding narration that captivates audiences. The extensive voice library allows users to select tones and styles that best fit their content.

Audiobook Narration

Authors and publishers can leverage Bantr to create engaging audiobook narrations. The natural-sounding voices make it easy to convert written content into audio format, allowing for a seamless listening experience for audiences.

E-Learning Content

Educators can utilize Bantr to develop interactive e-learning materials. By incorporating TTS into lessons and tutorials, teachers can make content more accessible and engaging for students, particularly those who benefit from auditory learning.

Game Character Dialogue

Game developers can harness Bantr's capabilities to generate character dialogue, bringing their narratives to life with expressive voice acting. This feature adds depth to gaming experiences, making interactions more immersive for players.

Rapid Social Media Content Creation

Marketing teams and social media managers can leverage Seedance 2.0 to rapidly produce a high volume of platform-specific video content. By quickly generating multiple versions of promotional clips, animated explainers, or engaging short-form videos in various aspect ratios (9:16 for Reels/TikTok, 1:1 for Instagram), teams can maintain a consistent posting schedule and A/B test content without extensive production timelines or resource allocation.

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. This allows for the fast iteration of visual ideas, camera movements, and scene compositions during pre-production. Teams can evaluate creative directions and present tangible visual concepts to clients or stakeholders before committing to full-scale filming.

Product Demonstration and Explainer Videos

Businesses can create polished product demo and explainer videos directly from reference images of their products or UI screenshots. The Image-to-Video mode can animate the product, showcase features, or simulate user interactions. The integrated audio generation can add voiceover and sound effects, resulting in a professional, engaging video asset suitable for websites, sales pitches, and customer education.

Brand-Consistent Advertising Campaigns

For brands running multi-channel advertising campaigns, Seedance 2.0's reference-first workflow ensures visual consistency across all assets. A core brand image or style guide can be used as a reference to generate a series of video ads, ensuring uniform character appearance, color grading, and aesthetic tone. This maintains brand integrity while enabling the scalable production of video ads tailored for different platforms and messaging angles.
