Automated multicam video editing uses audio energy levels to switch between synchronized camera recordings second-by-second, rendering a single MP4 output via ffmpeg. This process requires the polysync tool to generate edit decision lists and render the final video file.

Yes, you can add an optional picture-in-picture overlay when combining multiple camera angles. The multicam editing process creates a comprehensive main video feed and supports embedding a secondary PiP overlay directly into the final MP4 output.

The best way to sync multiple camera recordings is ensuring each video file includes its corresponding `.sync.json` metadata. The polysync tool then reads these synchronization files to accurately align camera angles for automated audio energy-based switching.

You need both ffmpeg and polysync to render multicam edits effectively. Polysync generates the edit decision list from audio energy analysis, and ffmpeg handles the actual rendering of the synchronized camera cuts into the final MP4 video.

Audio energy detection for switching camera angles analyzes the audio tracks of synchronized recordings to determine the loudest source second-by-second. It then generates an edit decision list that selects the camera angle with the highest audio energy for each timestamp.

Prerequisites for combining multiple camera angles include having synchronized video recordings with `.sync.json` files, and installing both ffmpeg and polysync. You must run the polysync edit command to generate an EDL before rendering the final MP4 output.
