AI Flow: Video

"""Compose a 1280 x 720 thumbnail: the narrator (cut out) pointing at the product picture, and a two-line headline.
  python3 compose.py --person pose-cut.png --product product.jpg --line1 "AI built this" --line2 "for my daughter." \
      --tip 1230,555 --out thumb.jpg [--font /path/Bold.ttf] [--scale 0.54]
--tip is the fingertip in the person photo (pixels). The person is placed so the fingertip lands on the product
picture's edge. No logo is added: the film is the user's own."""
