A system obtains respective video data generated by multiple recording devices. Each video data includes multiple image frames. For each recording device: based on a time value, the system identifies events captured in the video data generated by the recording device.

A graphical interface is generated that concurrently outputs each video segment for each recording device. ## Claims ### Claim 1 A computer-implemented method, comprising: identifying, based on a time value, video data generated by a recording device and that shows one or more events;
