Shotcut is open source free video editing software. It’s one of those open source programs that really demonstrates how much a dedicated development community can improve a platform given time. In earlier versions, the Shotcut interface was a little bare, but later releases have added extra dockable panels, an intuitive timeline, and other touches that put Shotcut in the same league as premium video editors like Adobe Premiere Pro.

This video tool supports non-destructive audio and video editing, meaning you can compile effects without any quality loss. You can also use this platform to do color keying and grading operations, as well as more basic clip splicing and trimming. 

Perhaps the coolest thing about Shotcut is its ability to work with more or less any format of video, audio, or photo media. That’s largely thanks to FFmpeg, an open source video framework that sits under the hood of the Shotcut program.
