This blog post will explain how to use FFMPEG to cut out a section of a video. The FFMPEG command will use input.mp4 as the input video. The -ss flag will determine the starting position of the section that is going to be cut out. The -to flag will determine the ending position of the section that is going to be cut out. The -c:v copy and -c:a copy flags will copy the commands audio and video output into the file output.mp4.

ffmpeg -i input.mp4 -ss 00:00:00 -to 00:03:18 -c:v copy -c:a copy output.mp4
