Users can also define the frames from the video needed to be captured.

$ ffmpeg -ss 00:00:01 -t 00:00:04 -I video.mp4 output_file%3d.jpg
$ ffmpeg -I video.mp4 -c:a libmp3lame -q:a 0 -map a output_file.mp3

There is also a way to extract specific frames of audio from any video.

$ ffmpeg -I video.mp4 -ss 00:00:08 -t 00:00:10 -q:a 0 -c:a libmp3lame -q:a 0 -map a output_file.mp3

Cropping video is also another functionality supported by FFmpeg.

$ ffmpeg -I video.mp4 -filter:v “crop=w=50:h=200:x=100:y=200” output_file.mp4

Write-out the following command to trim the video by specifying the starting and ending part.

$ ffmpeg -I video.mp4 -ss 00:00:20 -t 00:00:10 -c:v h264 -c:a aac output_file.mp4
