A skill for generating video with Layer: text-to-video, animating a still, extending a clip, camera motion, audio and lip sync. Useful when a prompt returns the wrong motion.

## What it does

The skill teaches the agent to write video prompts differently from image prompts. A video prompt describes what changes over the clip, not the scene: what moves, in which direction and how fast, how the camera behaves, what the pace is. Describe only the scene and you get a near-still frame with drifting artefacts — the most common failure here.

Pick the use case first: `text_to_video` from nothing, `image_to_video` to animate an existing frame, `video_extend` to continue a clip, `video_editing` to alter one. When an approved still already exists, `image_to_video` wins almost every time: the first frame fixes the character, palette and composition, so the model spends its capacity on motion. Pass the still as `init_image` or `first_frame`; where a model takes both `first_frame` and `last_frame`, supplying both controls where the shot ends up.

Clip length is per-model and short. Some models choose their own length and ignore `duration_seconds`, so filter for `fixed_duration` when the clip has to land on an exact length. Audio and lip sync are separate capabilities and need their own filters: `filter.capabilities` is an object of booleans, like `{generate_audio: true}`. Video hits a tighter rate limit than images: 60 generations per minute per user, of which at most 30 may be video. For a seam-free loop, filter for the `loop` capability instead of asking for a loop in the prompt.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add layerai/skills --skill layer-video -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add layerai/skills --skill layer-video -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add layerai/skills --skill layer-video -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install layerai/skills layer-video
```

2. **Manually: put the files in place**
- File: `.github/skills/layer-video/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add layerai/skills --skill layer-video -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/layerai/skills --path skills/layer-video
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add layerai/skills --skill layer-video -a opencode
```

### Claude.ai

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

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/layerai/skills/tree/HEAD/skills/layer-video/SKILL.md

## When to use it
- animate an approved key frame into a short clip
- get a seam-free loop that does not jump at the cut
- set camera motion instead of the default drift
- generate native audio or lip sync for a character line
- plan a multi-shot ad, trailer or cutscene

## Example prompts
- Animate this approved character key frame into a 5-second idle loop.
- Find a model for image_to_video with loop and fixed_duration, then show me its parameters.
- The prompt gives a near-still frame — rewrite it to name the motion, the camera and the rate.

# Layer Video Generation

## Overview

Video models take a prompt the way a director takes a shot list, not the way an illustrator takes a
brief. A video prompt describes **what changes over the clip**. A prompt that only describes the
scene yields a near-still image with drifting artefacts, which is the most common failure here.

Pick the use case first: `text_to_video` from nothing, `image_to_video` to animate an existing
frame, `video_extend` to continue a clip, `video_editing` to alter one. The loop and spend gate are
in the `layer` skill. Assembling finished clips into one deliverable is `layer-video-timeline`.

If a sibling skill named here is missing from your available skills, ask the user to install it
(`npx skills add layerai/skills --skill <name>`); unattended, proceed from tool schemas and flag the
gap.

## Anchor on an image whenever one exists

`image_to_video` beats `text_to_video` almost every time a look has already been approved. The first
frame fixes the character design, palette, and composition, so the model spends its capacity on
motion instead of re-inventing the subject. Attach the still as `init_image` or `first_frame`
depending on what the model accepts, and where a model takes both `first_frame` and `last_frame`,
supplying both is the most reliable way to control where a shot ends up.

Generate the key frame with `layer-image`, approve it, then animate it.

## Writing the motion

Name three things, in this order:

1. **Subject motion**: what moves, in what direction, at what speed. "The banner snaps taut in a
   gust, then settles" is a shot. "A banner" is a photograph.
2. **Camera**: static, slow push in, orbit, handheld drift, crane down. State "locked-off camera"
   when the camera must not move, because models add drift by default.
3. **Rate**: slow, deliberate, sudden, gradual over the full clip. Models otherwise pick a middling
```
