Seedance FAQ
Answers to the most common questions about Seedance: access, pricing, commercial use, capabilities and limits.
What is Seedance?
Seedance is a family of AI video generation models developed by ByteDance. The latest version, Seedance 2.5 (July 2026), generates continuous 30-second video clips in a single pass with native synchronized audio, up to 4K resolution, and support for up to 50 multimodal reference inputs.
How can I use Seedance?
Consumers can access Seedance through ByteDance's creative platforms: Dreamina (international) and Jimeng (China). Developers and enterprises can integrate it via the Volcano Engine API. Some third-party API aggregators also offer Seedance endpoints.
Is Seedance free to use?
Dreamina and Jimeng typically offer a limited free credit allowance for new users, with paid subscriptions for higher volumes and priority queues. API access via Volcano Engine is billed per second of generated video, with price varying by resolution and model version.
Can I use Seedance videos commercially?
Usage rights depend on the platform's terms of service and your subscription tier — check the current Dreamina / Jimeng / Volcano Engine terms before commercial use. Also note that generating content that imitates real actors, copyrighted characters or trademarked material can expose you to infringement claims regardless of the tool's license.
How long can a Seedance video be?
Seedance 2.5 generates up to 30 seconds in a single pass without stitching. A beta long-video mode extends clips to around 3 minutes. Earlier versions (2.0, 2.0 mini) generate roughly 10-second clips per pass.
Is Seedance better than Sora or Veo?
Each model has different strengths. Seedance 2.5's headline advantages are single-pass 30-second generation, 50 reference inputs and region-level local editing. Sora and Veo excel in their own ecosystems and integrations. See our comparison pages for a detailed breakdown.
Does Seedance generate audio?
Yes. Seedance 2.5 co-generates audio in the same pass as the video — music, sound effects, dialogue and lip-sync are natively synchronized rather than added afterward. You can describe the audio you want directly in the prompt.
What are multimodal reference inputs?
References are images, video clips or audio files you attach alongside your text prompt to control the output — for example a character photo to lock a face, a video clip to copy camera movement, or a song to set the rhythm. Seedance 2.5 accepts up to 50 references in one generation.
Should I write prompts in English or Chinese?
Both work, since the model is trained bilingually. English prompts tend to have broader community examples to borrow from; Chinese prompts work naturally on Jimeng. Whichever language you use, structure matters more: subject, scene, camera, lighting, style, audio, and pacing.
