If the file is Mov or mp4 format it can be done very easily with Registrator Viewer

I use ffmpeg:

ffmpeg -ss 65 -i a119-1.mp4 -t 21 -c copy out1.mp4

this would extract footage starting at 65 seconds up to 86 seconds (21 seconds long) without re-encoding

If you have a Mac computer and are using QuickTime Player (supplied with the OS) you can easily Split and Trim video clips to any desired length. You can also combine clips using the "Add Clip to End" menu selection.

avidemux, handbrake can do the job :

2nd vote for avidemux. it can do it without re-encoding and works on mac/linux/windows. Registrator Viewer looks more geared towards archive/organization.

You may need to send unaltered files for legal reasons depending on what happened.

Registrator Viewer is not reencoding and is very simple to use in 4 steps
Ctrl+Home for start of the cut
Ctrl+End for end of the cut
Ctrl+S to save the desired segment of the video.

Registrator Viewer is also good for Novatek platform to remove the 1 second overlap when joining files that are exported

We should post the link then: http://www.registratorviewer.com/index_en.html

btw, splitting in VLC looks painful

Yep, lots of ways to do this. Yet another option: You can use Export Movie Fragment feature of Dashcam Viewer produce a clip

@dave798 the thread title is wrong. Instead of crop you should use Cut or Trim. Will be nice if you will edit the topic title.

enjoy,

yeah i believe crop is if you zoom in one some part of the footage.
