Schema

[Core Function] Seedance 2.5 R2V is ByteDance Dreamina Seedance 2.5 reference-to-video generation from up to 30 reference images. [Strengths] It supports optional reference audio, fixed or adaptive aspect ratio, 480p/720p/1080p, 4-30 second duration, and mp4 or mov output. [Best For] Highly recommended for: multi-image character consistency and image-led storytelling on Seedance 2.5. [Limitations] Do NOT send first_frame_image, last_frame_image, or video_urls. Do NOT use audio_urls alone. Do NOT use this model when the user requires 4k output. [Routing] Prefer this model when the user provides reference images without a driving video. Use Seedance 2.5 I2V for first-frame or first-and-last-frame animation, Seedance 2.5 T2V for text-only requests, and Seedance 2.5 V2V when reference video is required.

输入

Optional. Video description. Maximum 10000 characters. Use @Image1 and @Audio1 when referencing inputs.
Required. Reference image URLs (1-30). Do not pass first_frame_image or last_frame_image.
提示：可拖拽文件、从剪贴板粘贴（Ctrl/Cmd+V），或提供 URL。
Optional. Reference audio URLs (1-10). Must accompany reference_images; audio-only is not supported.

Whether to keep the camera fixed during generation
Video duration in seconds. Allowed values are integers from 4 to 30
Task expiration time in seconds
Whether to generate an audio track with the video
Task type hint for multimodal reference only (requires `reference_images`). Do not pass this field for first-frame or first-last-frame generation. `auto` infers the type from the prompt and inputs. `reference` generates a new video from reference images; `ratio` and `duration` have no special constraints.
Output video container. mp4 for general playback; mov for higher color precision in editing workflows
Aspect ratio of the generated video.
Specifies the resolution tier for the generated video. Seedance 2.5 supports 480p, 720p, and 1080p
Whether to return the last frame of the generated video
Random number seed for reproducibility. Use -1 for random. Identical seeds cannot guarantee completely identical results
