FAQ

What is Seedance 2?

Seedance 2 is ByteDance's next-generation AI video model built around strong prompt following, native multi-shot narrative coherence, and fast video generation up to 1080p — all in a creator-first text-to-video and image-to-video workflow.

What makes Seedance 2 stand out?

Seedance 2 features native audio generation, strong multi-shot character consistency, and high-quality 1080p output — making it ideal for narrative short-form content and ads.

Should I use Text-to-Video or Image-to-Video?

Use Text-to-Video when you want to build a scene from scratch with full creative control. Use Image-to-Video when you already have a reference frame or character sheet and want the motion to stay anchored to that visual.

Is Seedance 2 good for ads and short-form content?

Yes. Its 5–12 second output range matches the most common ad and social placements, and native audio means the clip is ready to test immediately without extra sound design.

What is a simple prompt structure that works well?

Lead with the subject and action, then add environment and mood. For example: 'A young woman runs through a neon-lit Tokyo alley at night, rain-soaked, cinematic slow motion.' Keep it specific but leave room for the model to interpret atmosphere.

How long should Seedance 2 videos be?

For social and ad content, 5–8 seconds is the sweet spot — long enough for a clear beat, short enough to hold attention. Use 10–12 seconds when you need a complete three-act micro-story.

How do you keep outputs consistent across a series?

Reuse the same core prompt structure and anchor phrases for each character or location, and keep the aspect ratio and resolution fixed. Slight variations in action or camera direction will feel cohesive as long as the subject description stays identical.

What should you avoid in a prompt?

Avoid stacking too many unrelated subjects or conflicting styles in one prompt. Vague mood words alone — like 'epic' or 'beautiful' — add little; replace them with specific visual cues such as lighting, camera angle, or motion style.

Can Seedance 2 replace video editing?

It reduces the editing workload significantly, especially for short clips. However, assembling multiple clips into a longer cut, adding titles, or syncing custom audio still benefits from a dedicated editing step after generation.

What is a realistic expectation for the first generation?

Treat the first generation as a draft. Aim for a clear story beat and clean motion, then refine one detail at a time until the clip is ready to post. It improves fastest when you give focused edits rather than rewriting the entire prompt each time.
