It leverages Shopify's public products.json to generate product videos automatically at low cost (~$0.12 per video), preserving the original product photo as the anchor frame to avoid AI hallucinations.
Before: ordinary catalog photos, pulled straight from deathwishcoffee.com's public products.json.
↓ gen4.5 image → video ↓
After: a Reels-ready 9:16 video per product, the catalog photo preserved as the anchor frame. Full-quality MP4s in examples/.
Point it at a store. It pulls each product's photo, animates it with gen4.5 (your catalog shot is the anchor frame, so the product stays true, no hallucinated variants), and exports a Reels-ready 9:16 video per product.
Your first run: about ten minutes. A 5-second clip is 60 credits (~$0.60), so the $10 minimum credit purchase covers around 16 product videos.

That second command is the whole point: most Shopify stores expose products.json publicly, so this runs against your real catalog with zero app installs and zero auth dances.
