Seedance 2.5 4K Image to Video is a ByteDance image-to-video endpoint that animates a single still into a 4K clip. It suits product hero shots, campaign cutdowns, and character beats where texture like hair, fabric, or brushed metal needs to stay readable at full size.
The input and prompt behaviour are the same across resolutions; Seedance 2.5 4K Image to Video locks the output at 4K instead of 480p, 720p, or 1080p. Use a cheaper tier to test framing and motion, then rerun the same still and prompt here for the delivery version.
Seedance 2.5 4K Image to Video takes a prompt describing motion and camera, an image URL for the still to animate, duration from 4 to 30 seconds with a default of 5, and generate_audio. There is no aspect_ratio field, because the output frame follows your input image.
Feed a sharp, well-exposed still at or above the target frame size. Soft, heavily compressed, or already-enlarged sources limit what Seedance 2.5 4K Image to Video can resolve, since the model animates the detail present in your input rather than inventing missing texture.
Seedance 2.5 4K Image to Video is billed at $1.79 per second of generated video, scaling linearly with the duration you choose. Generations draw down your RunComfy usd / credits balance.
