PoYo Seedance 2 Video Generation

Use this skill for Seedance 2 jobs on PoYo. It covers standard and fast variants, text-to-video, first/last-frame control, and multimodal reference-to-video workflows.

Use When

• The user explicitly asks for Seedance 2, Seedance 2.0, seedance-2, or seedance-2-fast.
• The task is a 4-second to 15-second video clip from text, first/last frames, or multimodal references.
• The workflow needs generated audio, reproducible seed, or reference images, videos, and audio.

Model Selection

• seedance-2: default standard-quality variant; supports 480p, 720p, and 1080p.
• seedance-2-fast: faster, lower-cost variant; supports 480p and 720p only.

Key Inputs

• prompt, resolution, and duration are required inside input.
• duration supports integer values from 4 to 15.
• aspect_ratio is optional and supports 1:1, 21:9, 4:3, 3:4, 16:9, 9:16.
• image_urls supports up to two images for first and last frame control.
• reference_image_urls, reference_video_urls, and reference_audio_urls support multimodal reference-to-video workflows.
• Do not combine image_urls with any reference_*_urls field in the same request.
• generate_audio and seed are optional.

Execution

• Read references/api.md for endpoint details, field constraints, example payloads, and polling notes.
• Use scripts/submit_seedance_2.sh to submit a raw JSON payload from the shell.
• If the user only needs a curl example, adapt one from references/api.md instead of rewriting from scratch.
• After submission, report the task_id clearly so follow-up polling is easy.

Output Expectations

When helping with this model family, include:

• chosen model id
• whether the request is text-to-video, first/last-frame, or multimodal reference-to-video
• final payload or a concise parameter summary
• whether generated audio or seed control is enabled
• returned task_id if a request was actually submitted
• next step: poll status or wait for webhook
