Seedance 1.5 Pro is a next-generation AI audio-video generation model developed by ByteDance’s Seed research team that produces native, synchronized video and sound in a single unified pass from text prompts and image or visual inputs, eliminating the traditional need to create visuals first and add audio later. It features joint audio-visual generation with highly accurate lip-sync and motion alignment, supporting multilingual audio and spatial sound effects that match the visuals for immersive storytelling and dialogue, and it maintains visual consistency and cinematic motion across multi-shot sequences including camera moves and narrative continuity. Able to generate short clips (typically 4–12 seconds) in up to 1080p quality with expressive motion, stable aesthetics, and optional first- and last-frame control, the model works for both text-to-video and image-to-video workflows so creators can animate static images or build full cinematic sequences with coherent narrative flow.

Seedance 2.0 is ByteDance’s advanced AI video generation platform built to turn creative inputs into cinematic-quality videos. It supports text prompts, images, audio, and video, blending them into polished visuals with smooth transitions and native sound. The platform uses sophisticated multimodal and motion synthesis to preserve visual consistency and character identity across multiple scenes. Users can combine up to twelve reference assets in a single project, enabling complex storytelling without manual editing. Seedance 2.0 automatically plans camera movement and pacing, giving creators director-level control with minimal effort. The system is capable of producing high-resolution video output, including 1080p and above. Its rapid popularity highlights its ability to generate engaging animated and narrative-driven content from simple inputs.
