I'm looking for a good free video editing software, as I'm seeking to upload some videos to Youtube (or at least just to tinker with on my computer). Every software I've found so far seems to look free at first, but after installing it, I find it says it's only free for a "7 day trial period", and then they expect you to buy it. Is there not any video editing software out there that's JUST "free"? Or would I be better suited plunking down some cash for a good quality video editing software? Any help would be appreciated.
