What Seedance 3.0 is
Seedance 3.0 is an AI video generation model from ByteDance, shown on the seedance3ai.ai website. The page positions it as a model for video generation with synchronized audio, meaning speech, ambient sound, and effects are produced together with the picture. You direct it by combining text, images, video, and audio references, and it supports up to fifty multimodal references in one job. A single generation can run up to thirty seconds at 480p, 720p, or 1080p, with several aspect ratios and batch output of up to ten videos. It also covers cross-shot consistency, camera movement intent, and continuation editing.
What you can do with it
- Generate a short video and matching audio from a written brief.
- Use image, video, and audio references to guide characters, scenes, and sound.
- Keep characters, props, lighting, and style consistent across connected shots.
- Continue an existing video or edit it by description to extend a story.
Who it is for
- Advertising and marketing teams that need many creative variants fast.
- Educators and trainers building visual explanations of scenes or steps.
- Social creators and short film makers working on hook-driven stories.
What to watch out for
The page does not publish pricing and points to cloud APIs and platforms, so access terms and free allowances can change at any time. Output length and resolution are capped by the model settings, so plan shots to fit. Generated footage still needs human review for factual accuracy, likeness rights, and platform rules before you publish, especially where real people or brands appear. For team use, agree on naming and editing conventions in advance to avoid version conflicts or duplicated work.
