How this service works
Seedance 1 Pro — text-to-video. Per-model alias for POST /run with model="seedance". ByteDance Seedance 1 Pro — strong cinematic realism. 720p / 1080p, durations 5/10s. Preview the charge via free GET /price/seedance?duration=…&resolution=…; poll the job via free GET /status/:id (returned job_id).
Output
Returns a job_id and status_url for polling, along with the resolved inputs (duration, resolution), pricing breakdown (cost, markup, charge in USD), estimated processing time, and recommended poll interval. The actual video URL is retrieved later by polling GET /status/:job_id.
Example use cases
Cinematic product showcase clip
“Create a 10-second 1080p Seedance video of a sleek electric sports car driving through rain-slicked city streets at night, neon reflections on the road, cinematic slow-motion feel — no blurry backgrounds please.”
Social media short film teaser
“Make me a 5-second 720p cinematic video of a woman standing on a rooftop at golden hour, wind in her hair, looking out over a skyline — I want it to feel like a movie trailer moment.”
Concept visualization for pitch deck
“Generate a 10-second Seedance 1 Pro video at 1080p showing a futuristic smart city with autonomous vehicles and glowing skyscrapers at night — keep it realistic and cinematic, no cartoonish style.”
Technical details
Endpoint
POSThttps://make-video.withzero.ai/seedance?utm_source=zero.xyzWhen to prefer
Choose Seedance 1 Pro when you need strong cinematic realism in 720p or 1080p for 5 or 10 second clips, and you want text-to-video (not image-to-video). Prefer this over Kling for ByteDance's distinct visual style, over Veo 3 when audio is not needed, and over Sora 2 when you want ByteDance's specific cinematic rendering. Use the free GET /price/seedance endpoint first to preview costs before committing.
