Seedance 2 is the next-generation AI video generation model developed by ByteDance's Seed team. Built on native audio-visual synchronization architecture, Seedance 2 integrates four input modalities — Text, Image, Video, and Audio — to produce multi-shot cinematic narratives with consistent characters, emotion-driven expressions, and phoneme-level lip-sync in over 8 languages. Seedance 2 delivers up to 2K resolution output, 30% faster than its predecessor.
Seedance 2 addresses the fundamental challenges in AI video creation — from uncontrollable outputs to inconsistent characters — through four breakthrough capabilities.
Seedance 2 accepts a mixed input of up to 12 files — images, videos, and audio — and accurately understands your creative intent. Use an image to define visual style, a video to specify character motion and camera movement, and audio to drive rhythm. No more struggling with complex text prompts alone.
Seedance 2 significantly enhances understanding of physical laws and instruction following. Facial features, clothing details, and overall visual style maintain high uniformity throughout every clip — enabling reliable character IP continuity for long-form content, brand storytelling, and commercial advertisements.
Beyond generation, Seedance 2 supports character replacement, content addition and deletion within existing videos, plus smooth video extension and concatenation based on prompts. Reshoot or tweak individual scenes without regenerating the entire clip — saving rendering time and computing costs.
The model natively supports audio input and generates synchronized visuals driven by rhythm. From complex camera movements hitting each beat to character lip movements matching reference audio, Seedance 2 achieves automated, high-level fusion of sight and sound for music videos and rhythmic ads.
Built on ByteDance's Dual-Branch Diffusion Transformer architecture, Seedance 2 simultaneously generates video and audio in a single forward pass.
Production-ready output across multiple formats, resolutions, and aspect ratios.
From e-commerce product showcases to narrative short films, Seedance 2 empowers creators across industries.
Generate compelling product promos, A/B test multiple creative variations, and produce localized campaign visuals across 8+ languages — all without a production studio. Seedance 2 accurately renders product textures, brand logos, and lifestyle scenes at broadcast quality.
Pre-visualize scenes, generate narrative sequences with consistent characters, and produce cinematic clips with director-level camera control. Ideal for short dramas, storyboarding, pitch decks, and social media content that demands professional production value.
Create animated explainers, training videos, corporate communications, and product demos. Turn complex concepts into engaging visual content with multilingual narration and synchronized lip-sync — no specialized video production software required.
Developed by ByteDance's Seed team — established in 2023 with labs across China, Singapore, and the United States — the Seedance line represents continuous advancement in AI video generation.
Seedance 2 is ByteDance's next-generation multimodal AI video generation model developed by the Seed team. It integrates four input modalities — Image, Video, Audio, and Text — to deliver native audio-visual synchronization, multi-shot storytelling, and up to 2K cinematic resolution. It addresses the long-standing "uncontrollability" challenge in AI video generation through precise composition restoration, complex action replication, and high character consistency.
Seedance 2 builds upon the Seedance 1.5 Pro foundation with four major upgrades: multimodal reference capabilities supporting mixed input of up to 12 files (images, videos, audio); significantly enhanced character consistency across scenes; native video editing and extension features; and audio-visual beat matching for rhythm-driven content. It also delivers 2K resolution output with a 30% improvement in generation speed.
Seedance 2 supports Text-to-Video (T2V), Image-to-Video (I2V), Audio-to-Video (A2V), video editing and extension, and multi-shot narrative generation from a single prompt with consistent characters and automatic scene transitions. It supports 480p to 2K resolution, multiple aspect ratios (16:9, 9:16, 4:3, 3:4, 21:9, 1:1), and 5–12 second clip durations.
Seedance 2 features phoneme-level lip-sync accuracy in over 8 languages including English, Mandarin Chinese, Korean, Japanese, Spanish, Indonesian, and select regional Chinese dialects such as Sichuan and Shaanxi. The model captures subtle vocal prosody and emotional tension in each language, enabling natural-sounding multilingual content production.
Seedance 2 is developed by ByteDance's Seed team, established in 2023 and dedicated to discovering new approaches to general intelligence. The team operates research labs in China, Singapore, and the United States, covering LLM, speech, vision, world models, infrastructure, and next-generation AI interactions. The Seedance model family is part of the team's broader multimodal AI research portfolio.
