I don't find trimming videos with ffmpeg particularly difficult, is just-ss xx -to xx -c copy basically. Sure, you need to get those time stamps using a media player, but you probably already have one so that isn't really an issue.
What I've found to be trickier is dividing a video into multiple clips, where one clip can start at the end of another, but not necessarily.
