Parameter

Parameter	Typ	Erforderlich	Beschreibung
model	string	Erforderlich	"seedance2" for Pro quality or "seedance2-fast" for Fast quality
mode	string	Optional	"standard", "real", or "wild" rendering mode. channel is accepted as an alias.
type	string	Optional	"text-to-video", "image-to-video", or "media-to-video" (auto-detected from media_urls/image_urls when omitted)
prompt	string	Erforderlich	Text prompt (3-2500 chars)
media_urls	string[]	Optional	Reference media URLs. Supports images, videos, and audio; detected by file extension.
image_urls	string[]	Optional	Image-only reference URLs. media_urls takes precedence when both are provided.
input_image	string	Optional	Deprecated. Alias for image_urls[0]
aspect_ratio	string	Optional	"1:1", "21:9", "4:3", "3:4", "16:9", or "9:16" (default: 16:9)
duration	string	Optional	"4" through "15" seconds (default: 4)
resolution	string	Optional	"720p" or "1080p" (default: 720p). "480p" is additionally available only when mode is omitted. Resolution values select quality presets; actual encoding profiles are tuned per mode.
