## Description

Dual Video lets you play multiple videos simultaneously on websites or on your phone, enabling side-by-side comparisons. You can compare two videos stored on your device or a video on a site, and even capture video with the in-app camera while another plays.

Usage and features include tapping a play box to pick a website or device video, a scroll-to-top button to quickly reset page position, bookmarking for favorites, and basic video trimming. It supports MP4 files; AVCHD (MTS, M2TS) must be converted to MP4 via the MTS button on the menu.
