What Is Seedance 1.5 Pro?
Seedance 1.5 Pro is a state-of-the-art AI video generation model built by ByteDance's Seed team, released in December 2025. Powered by a 4.5-billion parameter Dual-Branch Diffusion Transformer architecture, it represents a significant leap in controllable video synthesis — producing cinematic-quality clips with native audio, precise lip synchronization, and director-level camera movements.
Unlike models that bolt on audio as a post-processing step, Seedance 1.5 Pro co-generates audio and video simultaneously. This means sound effects, music, and speech are temporally aligned with the visual content from the ground up. Its phoneme-level lip sync engine supports 8 languages — English, Chinese, Japanese, Korean, Spanish, Portuguese, Indonesian, and Cantonese — making it the go-to choice for multilingual content creators.
The model supports three generation modes: text-to-video (describe your scene in natural language), image-to-video (animate a reference image), and first-last-frame interpolation (provide start and end frames, and the model fills in the motion). Combined with support for complex camera trajectories like dolly zooms, orbital shots, and tracking movements, Seedance 1.5 Pro gives creators Hollywood-level control without Hollywood-level budgets.
Key Features
Everything you need for professional AI video production, built into a single model.
Native Audio Co-Generation
Audio and video are generated together, not stitched after the fact. Sound effects, ambient audio, and speech are temporally aligned with visual content for natural, cohesive results.
8-Language Lip Sync
Phoneme-level lip synchronization across English, Chinese, Japanese, Korean, Spanish, Portuguese, Indonesian, and Cantonese. Perfect for multilingual marketing and localized content.
Director-Level Camera Control
Dolly zooms, orbital shots, tracking movements, crane sweeps, and more. Describe complex camera trajectories in your prompt and the model executes them with cinematic precision.
Three Generation Modes
Text-to-video from natural language prompts, image-to-video to animate reference images, and first-last-frame interpolation for precise motion control between keyframes.
10x Faster Generation
Model distillation reduces generation time to approximately 41 seconds per clip — an order of magnitude faster than comparable models without sacrificing visual quality.
Up to 1080p Resolution
Generate videos at 480p, 720p, or full 1080p with six flexible aspect ratios including cinematic 21:9 ultrawide. Ideal for any platform from mobile stories to widescreen displays.
