What is Seedance 3.0 AI?+
Seedance 3.0 AI is an online studio for creating videos with ByteDance’s Seedance video models. You can generate from a text prompt, animate a first frame (with an optional last frame), or guide a shot with image, video and audio references, and download the result as an MP4 with native audio.
Which Seedance models can I choose?+
The model picker lists every Seedance model in the studio with its modes, resolutions, durations and per-second credit cost. Pick a model before you generate; the selected model is shown on the request and in your history.
How long can a video be?+
You can choose 5, 10, 15 or 30 seconds depending on the selected model, in 16:9, 9:16, 1:1, 4:3, 3:4 or 21:9. Available durations and resolutions are shown for the model you pick.
Does Seedance 3.0 AI generate sound?+
Yes. Seedance creates ambience, effects, music and dialogue in the same pass as the picture. You can turn audio off for a request when you need a silent clip.
How do I write a good Seedance prompt?+
Write it like a director’s brief for one continuous shot: the subject and setting, then the camera (shot size, position, movement and speed), then the action in the order it happens, then the sound (ambience, effects, dialogue or music), and finally what must stay consistent. A few precise instructions work better than a list of cinematic buzzwords.
How much does it cost?+
Videos are paid with credits, priced per second of output for the selected model and resolution. The exact cost is shown before you generate, and credits for failed generations return automatically. Plans and one-time credit packs are on the pricing page.
Can I use the videos commercially?+
Rights in the videos you generate, including commercial use, follow the terms of service and applicable law, and you need the rights to any image, video or audio you upload. We do not guarantee exclusivity or copyright eligibility.
