Introduction To Seedance 2.5 1080p

ByteDance's Seedance 2.5 1080p turns a still image into a 1080p cinematic clip with sharper subject edges, richer texture detail, and more natural light and skin response for delivery-ready image-to-video. Trading plastic-looking draft renders for 10-bit-friendly color depth and cleaner high-frequency detail, it helps marketers, editors, and product teams move from stills to motion without heavy cleanup. For developers, Seedance 2.5 1080p on RunComfy can be used both in the browser and via an HTTP API, so you don't need to host or scale the model yourself.
Ideal for: Delivery-Ready Stills to Motion | Brand Product Clips | High-Detail Character Animation

Frequently Asked Questions

What is Seedance 2.5 1080p best used for?

Seedance 2.5 1080p is a ByteDance image-to-video endpoint that animates one still into a fixed 1080p clip. It fits delivery-ready product shots, character motion, and brand clips where edge detail and natural light matter.

How does Seedance 2.5 1080p differ from the 480p or 720p image-to-video variants?

Seedance 2.5 1080p keeps the same still-plus-prompt workflow but locks output at 1080p for sharper finals. Use 480p or 720p for cheaper drafts, then reuse the winning still and prompt here.

What inputs and duration does Seedance 2.5 1080p support?

Seedance 2.5 1080p requires a prompt and an input image. Duration spans 4 to 30 seconds (default 5). Output aspect follows the input image; generate_audio can add synchronized native audio.

Does Seedance 2.5 1080p support selectable resolution presets?

No. Seedance 2.5 1080p is fixed at 1080p by design. Choose a different Seedance 2.5 playground when you need 480p or 720p drafts.

Can developers call Seedance 2.5 1080p through the RunComfy API after trying it in the UI?

Yes. Prototype in the RunComfy model UI, then call the same Seedance 2.5 1080p template through the RunComfy API with matching parameters. Generations consume usd / credits on both paths.

How much does Seedance 2.5 1080p cost on RunComfy?

Seedance 2.5 1080p is billed at $0.57 per second of generated video. Longer durations scale linearly with the length you select.

When should I stay on Seedance 2.5 1080p versus a lower-resolution Seedance endpoint?

Stay on Seedance 2.5 1080p for client delivery, grading, and high-detail subjects. Use 480p or 720p first when you are still iterating prompts or camera direction.
