Seedance 1.5 Pro is a next-generation AI video creation model launched by ByteDance, specifically engineered for native, joint audio-video generation. Unlike traditional tools that add sound post-production, Seedance 1.5 Pro generates high-fidelity visuals and synchronized audio simultaneously in a single pass. This breakthrough allows for a higher level of alignment between character lip movements, emotional tone, and performance rhythm, creating a truly immersive sensory experience.
A standout feature of Seedance 1.5 Pro is its unprecedented support for multilingual and dialect lip-syncing. Just describe the scene and the specific dialect, and the AI will accurately execute the video with local soul - whether it's a cinematic short film or a localized commercial. The model also features advanced cinematic camera control, making AI video suitable for professional-grade projects such as filmmaking, high-end advertising, and interactive gaming content.
