Edit Cut Video with FFmpeg

Overview

Automated pipeline for cutting highlights from live streams and fixing common playback issues (frame freezes, black screens, AV desync). Re-encode specific segments using FFmpeg's filter_complex at the raw frame level to ensure perfect synchronization.

When to Use

• You need to cut highlight clips from a long-form video or stream.
• You encounter black screens or frame freezes at the beginning of cut clips.
• Audio and video become desynchronized after cutting or concatenating clips.
• You need to ensure the final output is compatible with macOS (QuickTime).

Core Pattern

Instead of simple stream copying (-c copy), which causes keyframe and sync issues, use raw frame-level processing with -filter_complex and force re-encoding to standard formats.
