💡 This Skill includes references (resource) components.

What problem does it solve? Writing a video-to-video prompt that changes one element of real footage without re-rolling the subject's face, performance, or camera move is difficult; this Skill produces Seedance 2.0 prompts that lock the source plate and apply only the requested transformation. ## Core Features & Use Cases - Footage Transformation Prompts: Generates prompts for adding VFX elements (fire, creatures, morphing limbs), swapping environments around a preserved subject, and relighting or regrading a shot. - Preservation Guardrails: Builds @source declarations, lock-down clauses, NON-IP specs, and 4K mode-std settings so identity, wardrobe, framing, and camera motion survive the edit. - Timed Camera Moves: Anchors crash zooms and push-ins to dialogue with dual semantic and numeric timecode anchors, including prepended-intro duration budgeting. - Use Case: A user attaches a 6-second clip of themselves talking to camera and asks to place a giant photoreal chimp on the building behind them with a zoom synced to their spoken line; the Skill outputs a plain-text Seedance prompt with the source locked, the creature integrated with contact shadows and matching light, and the zoom anchored at the measured timestamp. ## Quick Start Attach your source clip and ask for a Seedance 2.0 video-to-video prompt that adds or changes one specific element while keeping everything else identical.

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

FAQPage Schema
How do I write a Seedance video-to-video prompt that keeps the original subject?

Declare the clip with an @source line that locks identity, face, wardrobe, performance, framing, and camera motion, then describe only the one change. Repeat the most fragile guardrail, such as face and identity unchanged, at the end of the action.

How do I sync a crash zoom to a spoken line in Seedance?

Anchor the move twice: semantically with the exact quoted line and numerically with a second mark read from the source audio. Keep SFX and source dialogue only in the specs so the talk track survives, and leave a 2-3 second tail for the payoff.

What resolution and mode should Seedance 2.0 footage transforms use?

Run transforms in Seedance 2.0 std mode at 4K, since faces and lip-sync hold at 4K where they warp at 1080p. Fast mode caps at 480p/720p and Cinema Studio caps at 1080p, so neither can deliver a 4K transform.

Why does my added creature look pasted into the footage?

Color matching alone is not enough; you must match key light direction, environmental bounce, atmospheric haze, depth of field, and edges, plus a real contact shadow. If it still reads as CG, attach a reference photo of the real animal as a texture-only input.

When should I use video-to-video instead of generating a scene from scratch?

Use video-to-video when a real clip is the starting point and its subject, performance, or camera move must survive the edit. For a brand-new scene built from image references with no source clip to preserve, the general Seedance director skill applies instead.

What are the Seedance 2.0 input limits for source clips and references?

Seedance 2.0 accepts up to 9 images, 3 videos totaling 15 seconds, 3 MP3s totaling 15 seconds, and 12 mixed inputs overall, with generation durations of 4-15 seconds. A source clip plus one texture reference fits comfortably within these limits.
