💡 Developer's Insight: Solving the "2-Second Drift"
“While building this extractor, I tested over 100 long-form podcasts. I discovered that YouTube's auto-caps often drift by up to 2 seconds during silent segments. Unlike standard downloaders, our tool uses a custom sync-correction algorithm to ensure your SRT files are ready for Premiere Pro or DaVinci Resolve without manual re-timing.”
