Multi-Camera Editing In Premiere Pro

Multi-camera editing has been a Premiere Pro feature since version 2.0.

You can use the Multi‑Camera Monitor to edit footage from multiple cameras, simulating live camera switching. You can edit footage from up to four cameras using this technique. For event videographers, this can be a huge time-saver.

Here's a video from Creative Cow's Aanarav Sareen on multi-camera work flow in Premiere Pro.
