Seedance 2.5 reference-to-video capability illustrated

Using a reference video as the anchor, this demonstrates how inputs are organized for the Seedance 2.5 reference-to-video pipeline: reference_video_urls is the required media input, and the prompt points to the reference material in order via placeholders such as @video1; parameters including duration, resolution, aspect_ratio, output_format, and generate_audio are all submitted according to the schema's enum/default values, illustrating how resolution tiers, duration ranges, and the audio-video sync switch affect the final output. Composition of the work: a reference video generated by the pipeline (as the sole required media), plus an explicit instruction-style prompt that constrains the model to follow the reference material's camera movement and subject appearance, outputting a 16:9, 720p, 10-second final video with audio. Applicable scenarios include: establishing a stylistic foundation for advertising storyboards and product demo films, maintaining subject consistency across serialized short videos, and serving as a sample for validating parameter and prompt syntax before integrating this pipeline. Note: this model ID is intended for reference-guided generation, not video editing or clip extension; the reference video must meet constraints such as mp4/mov, 854x480 or higher, 24–60 fps, 2–30 seconds, and a single file within 200 MB, with a combined duration not exceeding 30 seconds.
