A guide for writing physically specific visual-effects prompts for Seedance 2.0, a video-generation system.

In plain words
What is it for?
Use it to describe particles, energy, destruction, transformations, weather, magic, explosions, smoke, fire, water, and other visual effects.
Why use it?
It replaces vague effect labels with details about each effect's material, source, movement, interaction, timing, and end state.

About the project

seedance-2.0 is an agent-driven production pipeline for creating AI films from text, images, videos, and references, including audio and platform-specific workflows. Filmmakers and creators use it to plan scenes and generate coherent prompts for Seedance-related tools, while the catalogue contains skills from that workflow.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

seedance-vfx scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

seedance-vfx

Before producing prompt text, a prompt-ready block, a rewrite, an example, or a compiled clip, load the Director's Read, classify the brief, and complete its canonical narrative or non-narrative record. Translate that record into visible or audible carriers and keep its internal labels out of final generation prose.

VFX prompts need material behavior, source, timing, and consequence. Treat every effect as physical: it starts somewhere, interacts with light and objects, changes over time, and ends in a visible state. Avoid generic words such as magical, explosive, or cinematic unless they are translated into particles, fluids, smoke, light, debris, deformation, or energy behavior.

Intent

The user wants wonder, and wonder dies the moment it stops obeying physics. This skill's purpose is magic with a budget of cause and effect: every effect has a source, a journey, and an ending, so the impossible reads as witnessed rather than rendered.

Effects Contract

State: effect source, material, motion path, interaction with light, interaction with objects, dissipation, and endpoint.

Effect Prompt-ready phrase Stability note
Product particles gold dust particles spiral from behind the logo, catch the backlight, then settle on the table Keep logo and bottle rigid.
Energy thin blue electrical arcs crawl along the cable, briefly illuminating fingerprints on the plug Keep arcs attached to source.
Smoke cold white vapor rolls over the rim, sinks down the glass, and thins near the tabletop Describe density and direction.
Transformation paper edge chars inward from the corner, flakes curl and fall, final logo remains untouched Protect identity anchor.
Weather wind pushes rain diagonally across the frame, puddles ripple outward from each step Tie weather to surfaces.

VFX Integration Rules

Use one hero effect per clip. Anchor the source to a clear object or body part. Make the effect respect gravity, wind, collision, reflection, and occlusion. For VFX near faces, hands, logos, or text, keep the core identity stable and place the effect around it rather than through it.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
