SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Producing cinematic trailers, teasers, and multi-shot video clips with synchronized audio requires coordinating multiple AI video gateways, prompt structures, and provider-specific parameters, which is error-prone and inconsistent without a unified workflow. ## Core Features & Use Cases - Multi-gateway video generation: Route Seedance 2.0 requests through fal.ai, Replicate, Runway, or Higgsfield via the OpenMontage video_selector with automatic provider scoring and fallback. - Structured prompt methodology: Apply the Higgsfield prompt format with shot-structure openers, temporal markers, identity-lock language, and camera negations for multi-shot and lip-synced generations. - Reference-conditioned generation: Use up to 9 images, 3 video clips, and 3 audio clips to maintain character identity across shots with anti-drift fallback strategies. - Use Case: Generate a 10-second 21:9 cinematic trailer clip with multi-shot cuts, quoted dialogue lip-sync, and native sound effects by calling video_selector with preferred_provider set to seedance. ## Quick Start Ask the agent to generate a 10-second cinematic trailer clip with Seedance using a multi-shot prompt and save it to the project assets folder.

Frequently Asked Questions about seedance-2-0

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate a video with Seedance 2.0 in OpenMontage?▼

Call the video_selector tool with preferred_provider set to seedance, plus prompt, operation, aspect_ratio, duration, and output_path. The scoring engine picks whichever configured gateway (fal.ai, Replicate, Runway, Higgsfield) is available.

What prompt structure works best for Seedance 2.0 multi-shot videos?▼

Open with a shot-structure declaration such as the montage or single-POV opener templates, then add environment detail, character blocks, beat-by-beat choreography with temporal markers, and explicit camera negations like no cuts or no zoom.

Which API keys does Seedance 2.0 support across providers?▼

Seedance 2.0 works with FAL_KEY for fal.ai, REPLICATE_API_TOKEN for Replicate, RUNWAY_API_KEY for Runway Enterprise non-US plans, and HIGGSFIELD_API_KEY with secret for Higgsfield. Any one configured gateway is sufficient.

How do I keep character identity consistent across Seedance shots?▼

Use the reference-to-video endpoint with a clear front-facing portrait, reuse the same reference across all shots, and stack identity-lock phrases like the same character, no drift, and do not alter clothing category or primary color.

When should I use the fast variant instead of standard Seedance 2.0?▼

Use the fast variant only for b-roll, previews, or latency-constrained drafts at lower cost. Avoid it for slow-motion, multi-shot, or complex camera moves, since it routinely misses those on the first attempt.

What are the limitations of Seedance 2.0 video generation?▼

Clips cap at 15 seconds and 1080p on some endpoints, readable text rendering is unreliable, dialogue over six words risks lip-sync drift, and complex music scoring should be handled by dedicated audio tools instead.
