Workflow Examples

Hero Section Asset

bash

uv run {baseDir}/scripts/generate.py \
  --image-prompt "Sleek iPhone 15 Pro showing Islamic prayer app interface, dark green and gold accents, floating against pure black background, dramatic studio lighting, premium product photography, 8K quality" \
  --video-prompt "iPhone floating and gently rotating in space, subtle purple glow, smooth seamless boomerang motion, premium cinematic lighting, dark background" \

  --image-prompt "Minimalist smartphone displaying prayer time interface, clean UI, dark mode with gold accents, studio lighting" \
  --output-image feature.png \
  --resolution 2K

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
