Seedance 2.5 API — Frequently Asked Questions
Magic Hour's Seedance 2.5 API lets developers generate cinematic AI videos using ByteDance's Seedance 2.5 model via REST API. It supports text-to-video and image-to-video workflows with SDKs for Python, Node.js, Go, and Rust.
Sign up at magichour.ai, generate an API key from the Developer dashboard, and install an SDK or call the REST API directly. Seedance 2.5 requires a Creator, Pro, or Business plan and is not available on the free tier.
Seedance 2.5 supports text prompts plus optional start-frame and end-frame images on the image-to-video endpoint. Supported image formats include JPG, PNG, and WebP. The public text-to-video and image-to-video APIs do not accept separate audio or video reference uploads.
Seedance 2.5 generates videos up to 30 seconds per request. Within that duration it can produce multi-shot sequences with natural transitions.
Seedance 2.5 outputs at 480p and 720p resolution in 9:16, 16:9, and 1:1 aspect ratios.
Yes. Seedance 2.5 generates audio natively alongside video with synchronized sound. No separate audio pipeline or post-production layering needed.
Magic Hour offers subscription plans starting at $15/month (Creator), $39/month (Pro), and $99/month (Business), each including a monthly credit allotment. Credits are consumed per generation based on output length and model. You can also contact us to set up usage-based (pay-as-you-go) pricing. Seedance 2.5 requires a paid plan (Creator, Pro, or Business) and is not available on the free tier.
Seedance 2.5 has strict content filters that prevent humans in generated videos. It works best with structured prompts and reference assets for maximum control.
Sign up at magichour.ai/developer — no credit card required — to get an API key instantly. The key works across all Magic Hour API endpoints, but Seedance 2.5 itself requires a paid plan (Creator, Pro, or Business). Once subscribed, call it with our Python, Node.js, Go, or Rust SDKs.
Signing up is free and gives you an API key, but Seedance 2.5 is not available on the free tier — it requires a paid plan (Creator, Pro, or Business). Paid plans unlock Seedance 2.5 along with higher credit limits, concurrency, and commercial use rights.
