Output
- Images are saved in PNG format
- Videos are saved in MP4 format (H.264 encoded)
- Veo generation takes ~30-60 seconds (async polling handled automatically)
Notes
- Veo 3.1 requires 4-8 second duration (enforced by API)
- Video generation is asynchronous — script handles polling automatically
- Use
{baseDir}placeholder in paths — it resolves to the skill directory
