IMA Seedance2.0 Video Generator

Seedance 2.0 AI video generator — two models in one skill: Seedance 2.0 (ima-pro) for cinema-grade quality with high frame-rate temporal consistency, precise camera language control, and 2K output; Seedance 2.0 Fast (ima-pro-fast) for faster iteration. Supports text-to-video, image-to-video, first-last-frame, and reference-media video generation with image, video, and audio references. Works for cinematic prompting, storyboard-driven clips, consistent-character workflows, product demos, and short-form content generation. Requires IMA_API_KEY.

IMA Seedance 2.0 — OpenClaw Calling Protocol

Hard Rule

OpenClaw must call scripts/ima_video_create.py.

OpenClaw must not:

• build /open/v1/tasks/create payloads
• compute attribute_id
• compute credit
• build src_img_url
• build src_image
• build src_video
• build src_audio

Required Read Order

1. references/protocols/execution.md
2. references/protocols/event-stream.md
3. On demand:
   • references/contracts/create-task.md
   • references/contracts/credit-rules.md
   • references/contracts/payload-rules.md
   • references/flows/reference-image-to-video.md
   • references/limits/reference-media-rules.md

Supported User Intents

• text-to-video
• image-to-video
• first-last-frame transition
• reference-image-to-video
• multimodal reference-image-to-video with image / video / audio inputs

Input Entry Points

• --prompt
• --model-id
• --task-type when explicit task type is required
• --input-images
• --reference-image
• --reference-video
• --reference-audio
• --extra-params

Stop Conditions

Stop before task creation if:

• prompt is missing
• model cannot be resolved
• reference media preflight validation fails
• any reference media compliance verification fails
• create-task returns a hard failure

Task Type Rules

Input pattern	task_type
text only	text_to_video
one image	image_to_video
explicit first-last-frame with 2 images	first_last_frame_to_video
any video input	reference_image_to_video
any audio input	reference_image_to_video
multiple images without explicit first-last-frame intent	reference_image_to_video

Model ID Reference (CRITICAL)

Use exact model_id from this table. Do NOT infer from friendly names.

Friendly Name	model_id	Notes
Seedance 2.0	ima-pro	✅ Quality priority, 300~900s
Seedance 2.0 Fast	ima-pro-fast	⚠️ Speed priority, 120~600s

User input aliases:

• Quality/Professional/Pro/专业版/高质量 → ima-pro
• Fast/Speed/Quick/极速/快速 → ima-pro-fast
• Default/默认 → ima-pro

Model Selection Priority

1. User preference (if explicitly stated) → highest priority
2. Fallback default: ima-pro

Task	Default	Fast Alternative
text_to_video	ima-pro	ima-pro-fast
image_to_video	ima-pro	ima-pro-fast
first_last_frame_to_video	ima-pro	ima-pro-fast
reference_image_to_video	ima-pro	ima-pro-fast
