# vfx

Turns a plain clip into a cinematic AI-VFX shot: the skill reads every frame and the audio, writes the prompt, then re-renders the same shot through Seedance.

## What it does

You hand the skill a clip and one change you want in it. It pulls every frame locally with `ffmpeg`, tiles them into contact sheets of 25 (a 5×5 grid) and works through the audio: speech, music, SFX, ambience. That feeds a Seedance reference-to-video prompt which locks the face, gestures and camera move, and time-codes the change to the right beat. The same shot is then re-rendered with the VFX baked in.

Seedance treats the reference as a motion and style anchor, not a pixel-locked base, so fidelity lives in the prompt. Reading every frame instead of a sample is the mechanism here: skip that pass and you get a different face, a different room, a missed motion beat. One run produces one clip for one requested change.

You need the pika MCP available and a local `ffmpeg` in the run environment. Inputs are the clip (local file or public URL) and the change itself; resolution defaults to 1080p, with 4K or 720p only on request. The `fast` model covers 720p, `standard` covers 1080p and 4k. Rendering costs money and cannot be undone, so the skill stops at an agreement gate on prompt, resolution and cost before it generates.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Pika-Labs/Pika-Plugins --skill vfx -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/vfx/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/vfx/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Pika-Labs/Pika-Plugins --skill vfx -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/vfx/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Pika-Labs/Pika-Plugins --skill vfx -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/vfx/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Pika-Labs/Pika-Plugins vfx
```

2. **Manually: put the files in place**

2. **Platform CLI**
```bash
gemini skills install https://github.com/Pika-Labs/Pika-Plugins --path skills/vfx
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/vfx/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Pika-Labs/Pika-Plugins --skill vfx -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- turn a plain clip into a shot with VFX
- keep the face and gestures intact through a video re-render
- time a visual change to a music beat
- describe the source shot so Seedance does not lose it
- build contact sheets from every frame of a clip

## Example prompts
- turn the plaza into an open desert on a finger snap
- vfx: set the room on fire behind me, 1080p
- vfx: morph my jacket into glowing armor, --resolution 4k

# vfx

Maps a video-to-video VFX move onto the Pika MCP's **Seedance reference-to-video**, at **1080p by default** (bump to 4K, or drop to 720p, only if the user asks). The user hands you a clip + the change they want; you **read EVERY frame** (locally extracted with ffmpeg and tiled into contact sheets) **and understand the audio** (speech + music + SFX + ambience), author a Seedance-faithful prompt that locks the original (face, gestures, camera move) and time-codes the change to the right beat, then re-render the **same shot** with the VFX baked in. **One run produces one clip** for one requested change.

> For a 4K-only version of this skill with no resolution choice, see `/pika:4k-vfx`.

## How it works — why reading EVERY frame (and the audio) is the mechanism (do not skip the reading pass)
Seedance treats the reference video as a **motion/style anchor, NOT a pixel-locked base** — it does not copy the input frame-for-frame, it re-generates the shot guided by your prompt. So fidelity comes from the **PROMPT**: the more exhaustively the prompt describes the original (subject identity, exact gestures, camera move, framing, lighting, palette, wardrobe) **and the audio** (dialogue + lip-sync, music/SFX beats), the more the output reads as the *same* shot with the change layered on, at any resolution. **Reading EVERY frame — not a sample — is how you build that exhaustive description:** you locally extract all frames with ffmpeg, tile them 25-to-a-contact-sheet (5×5), and analyze every sheet so the prompt is built from the *entire* timeline rather than a handful of stills. Skip the read (or read only a sample) and the output drifts — a different face, a different camera move, a different room, a missed motion beat. The reading pass — all frames + the audio — IS the skill.
