Free Auto Cut Software for PC, Mac & Linux: Master Automatic Video Editing with Auto-Editor

Are you tired of trimming silence from your interviews, podcasts, or vlogs manually? With Auto-Editor, you can automate the entire process — removing silence, cutting scenes, and even syncing edits across multiple tracks — all without touching a timeline.

🔍 What Is Auto-Editor?

Auto-Editor is a powerful, open-source command-line tool that analyzes video and audio files and automatically removes unwanted sections such as silence, inactive segments, or uneventful scenes.

It uses sophisticated algorithms to detect:

Audio loudness (removes silence)
Motion activity (cuts out still frames)
Scene changes (splits clips by transitions)

This makes it ideal for automating repetitive editing tasks like trimming long podcast recordings, cleaning up raw interview footage, creating highlight reels, and preparing raw material for further editing.
