Frequently Asked Questions

Can I use Seedance 1.5 pro for commercial projects?

Yes. All paid plans include full commercial usage rights. Use generated videos for advertising, social media, marketing campaigns, client work, broadcasting, and entertainment production. No additional licensing or attribution required.

What makes it different from other AI video generators?

Seedance 1.5 pro is a joint audio video model that generates video and audio simultaneously not as separate steps. This native approach ensures perfect lip sync, coordinated spatial sound effects, and smoother storytelling without post production audio editing. Unlike competitors that stitch audio onto silent video, our dual branch architecture creates both modalities together from the start.

Which languages are supported?

English, Mandarin Chinese, Cantonese, Sichuanese, Shanghainese, Taiwanese, Japanese, Korean, Spanish, Portuguese, and Indonesian all with great lip sync and motion alignment across different accents and dialects.

How long are videos generated?

Current generation supports 4~12 seconds per clip. For longer content, create multi shot sequences with narrative coherence maintained across transitions using first/last frame control for character consistency.

Can I generate videos without audio?

Yes. Toggle native audio generation off for faster generation (20~30% speed increase) and lower credit cost (approximately 50% savings). Perfect for B roll, background footage, or when adding custom soundtracks.

Does it work in languages other than English?

Yes, with full support for 8+ languages. Prompts work in multiple languages, though English may produce slightly better results due to training data distribution. Audio generation and lip sync work excellently across all supported languages.
