I don't use this, but an R/C aircraft reviewer who does nice stuff on YouTube recommended this, so I bookmarked it. It's freeware along with other apps they offer (converters, CD ripper, etc.):

I did a great deal of investigating for user discovered bug complaints and their ease of use claims before going with this:

There is a newer version available:

However, you have to watch out because I don't know how many times I've read reviews where very serious users of previous versions of a particular video editor will point out that the newest version has serious issues.
From what I've found through reading many reviews, Windows video editors are notorious for innumerable bugs, mostly when run on newly released Microsoft Windows versions, I suspect because programmers are either doing tricks that aren't liked by the new OS, haven't learned and properly used the video related APIs and such of the new OS, or a combination of those factors.
Because of the HUGE variety of hardware that can be found in Windows machines, I think that many software houses that produce video editors for Windows simply release a new version without a huge amount of testing on different hardware, wait for bug complaints, then release patches... and release patches... and release patches.
This is an advantage of Apple machines where the hardware is known, but you pay more.
