Superside Seedance 2.5 Reference-to-Video
Seedance 2.5 Reference-to-Video on fal. Returns a native VIDEO plus the URL, so SaveVideo or PreviewVideo connects straight in. Endpoint: default - bytedance/seedance-2.5/us/reference-to-video fal price (2026-10-30): For 480p, your request will cost roughly $0.2205 per second of generated video, for 720p, you will be charged roughly $0.4730 per second of generated video, and for 1080p, roughly $1.164 per second of generated video.

Inputs (20)
| Name | Type | Default | Description |
|---|---|---|---|
| api_key | STRING | — | |
| promptopt | STRING | The text prompt used to generate the video. | |
| resolutionopt | COMBO | 720p | Video resolution - 480p for faster generation, 720p for balance, 1080p for high quality. |
| durationopt | COMBO | auto | Duration of the video in seconds. Supports 4 to 30 seconds, or auto to let the model decide based on the prompt. |
| end_user_idopt | STRING | The unique user ID of the end user. | |
| codecopt | COMBO | auto | 'auto' retains default video codec behaviour; 'H264' uses H.264; 'H265' uses H.265. |
| seedopt | INT | 0-1–2147483647 | Random seed for reproducibility. Note that results may still vary slightly even with the same seed. -1 = let the model choose. |
| audio_urlsopt | STRING | Reference audio to guide video generation. Refer to them in the prompt as @Audio1, @Audio2, etc. Supported formats: MP3, WAV. Up to 10 files. Each file must be 1.8 to 30.2 seconds and no larger than 15 MB; combined duration must not exceed 30.2 seconds. One URL per line. | |
| aspect_ratioopt | COMBO | auto | The aspect ratio of the generated video. Use 16:9 for landscape, 9:16 for portrait/vertical, 1:1 for square, 21:9 for ultrawide cinematic, or auto to let the model decide. |
| video_1opt | VIDEO | Reference videos to guide video generation. Refer to them in the prompt as @Video1, @Video2, etc. Supported formats: MP4, MOV. Up to 10 videos. Each video must be 1.8 to 30.2 seconds and no larger than 200 MB; combined duration must not exceed 30.2 seconds. Dimensions must be 300 to 6,000 pixels per side, aspect ratio 0.4 to 2.5, and frame rate 24 to 60 FPS. | |
| video_2opt | VIDEO | Reference videos to guide video generation. Refer to them in the prompt as @Video1, @Video2, etc. Supported formats: MP4, MOV. Up to 10 videos. Each video must be 1.8 to 30.2 seconds and no larger than 200 MB; combined duration must not exceed 30.2 seconds. Dimensions must be 300 to 6,000 pixels per side, aspect ratio 0.4 to 2.5, and frame rate 24 to 60 FPS. | |
| video_3opt | VIDEO | Reference videos to guide video generation. Refer to them in the prompt as @Video1, @Video2, etc. Supported formats: MP4, MOV. Up to 10 videos. Each video must be 1.8 to 30.2 seconds and no larger than 200 MB; combined duration must not exceed 30.2 seconds. Dimensions must be 300 to 6,000 pixels per side, aspect ratio 0.4 to 2.5, and frame rate 24 to 60 FPS. | |
| video_4opt | VIDEO | Reference videos to guide video generation. Refer to them in the prompt as @Video1, @Video2, etc. Supported formats: MP4, MOV. Up to 10 videos. Each video must be 1.8 to 30.2 seconds and no larger than 200 MB; combined duration must not exceed 30.2 seconds. Dimensions must be 300 to 6,000 pixels per side, aspect ratio 0.4 to 2.5, and frame rate 24 to 60 FPS. | |
| image_1opt | IMAGE | Reference images to guide video generation. Refer to them in the prompt as @Image1, @Image2, etc. Supported formats: JPG, PNG, WebP, BMP, TIFF, GIF, HEIC, HEIF. Max 30 MB per image. Up to 30 images. Total files across all modalities must not exceed 50. | |
| image_2opt | IMAGE | Reference images to guide video generation. Refer to them in the prompt as @Image1, @Image2, etc. Supported formats: JPG, PNG, WebP, BMP, TIFF, GIF, HEIC, HEIF. Max 30 MB per image. Up to 30 images. Total files across all modalities must not exceed 50. | |
| image_3opt | IMAGE | Reference images to guide video generation. Refer to them in the prompt as @Image1, @Image2, etc. Supported formats: JPG, PNG, WebP, BMP, TIFF, GIF, HEIC, HEIF. Max 30 MB per image. Up to 30 images. Total files across all modalities must not exceed 50. | |
| image_4opt | IMAGE | Reference images to guide video generation. Refer to them in the prompt as @Image1, @Image2, etc. Supported formats: JPG, PNG, WebP, BMP, TIFF, GIF, HEIC, HEIF. Max 30 MB per image. Up to 30 images. Total files across all modalities must not exceed 50. | |
| generate_audioopt | BOOLEAN | true | Whether to generate synchronized audio for the video, including sound effects, ambient sounds, and lip-synced speech. The cost of video generation is the same regardless of whether audio is generated or not. |
| bitrate_modeopt | COMBO | standard | Output bitrate mode. 'high' requests a higher-quality, larger-file encode from the model; 'standard' uses the default bitrate. |
| taskopt | COMBO | reference | The type of video generation task. Reference uses the supplied media as guidance. Editing modifies a reference video and automatically coerces aspect_ratio and duration to auto. Extension continues a reference video and automatically coerces aspect_ratio to auto. Auto leaves the task type unset so the model decides it from the prompt and references. |
