What's your problem?

You want to remove or extract a part of a video.

You could download, install and/or buy some advanced editing software which has such feature (like Adobe Premiere Pro), but it takes a lot of time and energy, especially if you are working with several, long videos and the software has to decodes and re-encodes the files every time.

 

The solution: FFmpeg.

FFmpeg is a complete, cross-platform solution to record, convert and stream audio and video.

Ffmpeg has a simple command that lets you edit the file as you will, almost instantaneously. It also works for audio files.

 

1. Download the package

 => Windows

 => Mac

 => Linux

 

2. How to use it ?

Just run the following line from your command prompt

ffmpeg -i InputPath.mp4 -ss 00:10:00 -t 00:00:05 -acodec copy -vcodec copy OutputPath.mp4

Where -i is the path to your file.

-ss is the start position in Hours:Minutes:Seconds

-t is how long a clip you want - again in HH:MM:SS

The acodec and vcodec tells ffmpeg just to copy the file without changing its other audio and video properties.

 

That's about the fastest you can get it done.
