## What is DuoLens Video?

Record two videos simultaneously with iPhone’s dual rear cameras — wide and ultra-wide — to capture independent footage at the same time. Customize a distinct aspect ratio for each lens, including 9:16, 16:9, 4:3, 3:4 and 1:1. Adopting true dual 4K 60fps recording, it delivers professional-grade video quality.
Perfect for content creators, influencers and product videography, a single shooting session produces vertical, horizontal and square content that’s fully optimized for TikTok, Reels and YouTube. You can directly save recordings to external drives to free up iPhone storage, break storage limits and empower all-scenario creation.
We provide watermark-free original footage, lag-free stable operation and high-precision real-time dual-camera synchronization.
