Mention video-editing software and two products will immediately spring to mind: Adobe Premiere and Final Cut Pro. There's a third option, though, that every professional and aspiring filmmaker should consider. DaVinci Resolve 15 is a single application for editing, color correction, audio postproduction and visual effects. It's made by BlackMagic -- the Australian company that builds those fancy video cameras -- and works on Mac, Windows and Linux. The best part is that it costs $299 and doesn't require an ongoing subscription. If you want to try before you buy, or don't feel like you need all those features, consider DaVinci Resolve 15 -- it includes a lot of the paid app's features free of charge.
