If you are looking for a video making and editing tool but don’t want to pay through the roof for it, there are a few options out there. But, based on my experience, I’d have to say one of the best is VSDC Free Video Editor. And yes, there is a decent free version.
Sure, there is a little learning required but you do a bunch with this program including placing videos side-by-side for viewing with a VR headset! It’s just a matter of experimenting and figuring out how.
