best editing programs

If you are a beginner when it comes to video editing then I suggest Hitfilm Express (there's a free version) but if you want to step up your game but still want something for free then Davinci Resolve is pretty good. There's also Adobe Premiere Pro but expensive unless you are willing to pirate it.

As for Photo editing, GIMP is pretty simple and free. Photoshop is where it's at and again, you'd need to pay for Photoshop or pirate it.
