Trimming and Extracting Audio

You can perform video editing tasks without opening a heavy GUI editor.

Extract Audio

Get the MP3 layer from a video file:

ffmpeg -i video.mp4 -vn -ab 320k audio.mp3

Trimming Video

Cut a video from 00:01:00 for 10 seconds:

ffmpeg -ss 00:01:00 -i input.mp4 -t 00:00:10 -c copy output.mp4

Placing -ss before -i is faster because it jumps to keyframes, but it might be slightly less accurate than placing it after.
