Probably overkill, but DaVinci Resolve - Mac, Win & Nix - is freeware unless you're a pro video editor who needs hardware integretion. That's literally one of the world's best video edit suites… for free. I honestly have no idea why it's not mentioned in that review, it's right up there with Final Cut Pro & Adobe Premier. Otherwise, people tend to ...

ImageMagick for titles & captions The other optional dependencies GIMP for image editting VLC for previews The really good news with the above is the total price, ($0....

I personally use Adobe Premier Rush and I love it. I have used Final Cut Pro and Adobe Premier in the past but for the price they're not worth it for creating simple split-screen videos. Here is a Youtube video of how to actually make one: https://www.youtube.com/watch?v=yc3Un8WacK4 It isn't free, but you can start by paying monthly for it on Adobe and ...
