Beat Sync Reel

Description

Generates Instagram Reels where product image cuts are synced to audio beats. Accepts audio as a local file, URL, or search query. Uses librosa for beat detection, FFmpeg Ken Burns for scene animation, and Pillow for text overlays. No AI video generation — fully free, fast, and scalable.

What this skill does

1. 1Downloads audio from a local file, URL, or search query using yt-dlp, then detects beats with librosa.
2. 2Scrapes product images from an e-commerce URL using Shopify JSON, HTML, or Chrome DevTools fallback.
3. 3Classifies and orders images by type — hero, detail, alternate angle — and assigns each to a beat interval.
4. 4Generates Ken Burns zoom/pan clips per image using FFmpeg and stitches them into a beat-synced sequence.
5. 5Optionally adds a branded end card with product name, price, and CTA, then mixes the audio with fade in/out.
