title: FFmpeg: How do I split a 100GB MP4 file into several 1GB files?
body: <p>I've tried using the -fs switch, but it only creates a single file. The -f segment option allows me to use the -segment_time option, but that only limits the video duration, not its size.</p>
  
  <p>So, suppose I want to use ffmpeg to split a 100GB MP4 file into several 1GB MP4 files, what's the switch?</p>
