Question Free video editing software ?

I have a wildlife video camera that i leave out overnight to film foxes and badgers that visit my garden.
The videos are in 30 second segments and sometimes i get a segment that has been triggered but only has something visible on the last 5 seconds.
All i want to do is cut the empty section off the clips.
Maybe I already have something as part of Windows that I don't know about ?
