How to input only part of the video file in ffmpeg

Question

I'm using ffmpeg in order to process videos.

ffmpeg -i C:\test.mp4 [rest of the command]

When I use above command it process whole video. How can I select a paticular part of the video and process?

Answer 1

This can be done by using -ss and -t options.

-ss seeks for the start position

-t limits the duration

so the command is like this.

ffmpeg -ss 50 -t 10 -i C:\test.mp4 [rest of the command]

this processes 10 seconds of video, starting at 50 and going onto 60.
