ffmpeg

I found a very helpful tool today. If you’re editing videos, and are having issues with your editor due to file size, it’s easy to copy a segment out to another file using ffmpeg.

Download the exe from this site: http://ffmpeg.zeranoe.com/builds/, or if you’re not on windows you can find the other builds on http://ffmpeg.org.

Documentation is here: http://ffmpeg.org/ffmpeg.html

First, I dropped the exe in the directory with the video, then opened a command prompt in that same directory, and used this command to copy a clip from 33 minutes into the video that was 1 minute and 22 seconds long. The source video was named 2016-03-02_05-16.54.mp4 and it was output to test.mp4 in the same dir.

ffmpeg -ss 00:33:28 -t 00:01:22 -i 2016-03-02_05-16-54.mp4 test.mp4
