## Documentation

### skill-runway-video-gen

Wraps Runway Gen4 Turbo image-to-video API. Point at a product image, describe the motion, get an MP4. No browser needed.

### Usage

uv run scripts/generate_video.py \\
  --image product.jpg \\
  --prompt "water droplets falling, soft bokeh, slow motion" \\
  --output output.mp4 \\
  --duration 10 \\
  --ratio 720:1280

### Args

ArgDefaultDescription--imagerequiredPath to source product image--prompt""Motion description (optional but recommended)--outputrequiredOutput MP4 path--duration10Video length: 5 or 10 seconds--ratio720:1280Aspect ratio (vertical for TikTok)

### Config

API key is read from (in order):

RUNWAY_API_KEY environment variable
~/tiktok-api.json → runway.apiKey

### Cost

DurationCost5s$0.2510s$0.50

Always use 10s — you get more content to work with.

### Known quirks

Last 1–2s often freezes. Fix: stretch to 12s at 0.83x speed using MoviePy:

from moviepy import VideoFileClip
clip = VideoFileClip("output.mp4")
slow = clip.with_effects([vfx.MultiplySpeed(0.83)])
slow.write_videofile("output_12s.mp4", fps=30)

### Rate limits

No per-minute quota (unlike Veo). Runway charges per second of output.

### Pipeline integration

This skill feeds into skill-tiktok-video-pipeline as the video generation step. The pipeline handles slowmo stretch and caption overlay automatically.
