seedance-2.5-first-last-frame (balanced)

Generate a video transition between two images with Seedance 2.5. Input: prompt, images_list (required, exactly 2: [first_frame, last_frame]), resolution (480p/720p/1080p/4k, default 720p — price scales with resolution), duration (4-30s), aspect_ratio, seed. Use for: keyframe-driven scene transitions, before/after animation.

Request body

webhook_urlstring uri nullable
durationinteger

Video duration in seconds, from 4 to 30.

aspect_ratio'adaptive' | '16:9' | '9:16' | '1:1' | '4:3' | '3:4' | '21:9' | '9:21'
seedinteger nullable

Random seed for reproducible generation. Use -1 for random.

high_bitrateboolean
promptstring nullable
images_liststring[] nullable

First and last frame images, in order: [first_frame, last_frame]. Required unless draft_request_id is set.

resolution'480p' | '720p' | '1080p' | '4k'

Output resolution. Price scales with resolution — see the model's pricing table.

draftboolean

Generate a cheap 480p draft (resolution must be 480p or omitted when true — any other value is rejected). Finalize the draft you keep at 1080p by calling this same endpoint again with draft_request_id set to this request's request_id.

draft_request_idstring nullable

Finalize an earlier draft (submitted with draft=true) into a full 1080p render. Set to that draft's request_id; images_list/prompt/duration/seed are ignored and reused from the draft instead. resolution must be 1080p or omitted and draft must not be true (rejected otherwise); the draft must be completed and at most 7 days old.
