How to Automatically Add Random Audio to Videos with Python MoviePy Script
This video shares a Python script designed to fill silent videos with random background music using MoviePy. It picks audio files from a specified folder, matches or loops them to fit the video duration, then saves the result as a new video with integrated sound.
The idea came from managing repetitive post-production tasks—especially when dealing with batches of content like shorts or reels. This script helps automate part of that process by randomly assigning audio, looping it if it's too short, or trimming it if it's too long, making each video feel dynamic and fresh.
The setup uses moviepy.editor, scans for video formats like .mp4, .avi, or .mov, and selects .mp3 audio files. The newly generated videos are saved to an output folder, ready to be published or processed further.
This kind of automation is useful for creators, editors, and digital marketers who handle high-volume content. Instead of manually syncing music to every clip, this approach speeds up the workflow with consistency and flexibility.
No UI, just clean, focused scripting that does exactly what it's meant to: simplify your video pipeline while giving every video its own vibe.
