One major limitation is that you don't get support for all the export formats that you'd find in Lightworks Pro. Lightworks is an award-winning video editor that's completely free.

Lacks collaboration features found in Pro version.

This free video editor for YouTube was designed for Windows 10 64-bit and macOS 11, 10.15, and 10.14. You can also set a custom maximum undo level, access several default template options including 1080p Full HD, mix and balance audio, use a helpful select tool to grab everything before or after the playhead, and add unlimited video and audio tracks. Some of HitFilms' best features include the ability to auto-save as frequently as every minute, its dozens of keyboard shortcuts, colored labels (for 3D effects, text, models, composite shots, images, and more), and the option to crop a clip and animate it to control which part is visible. Plus, there's still a lot to like with this free YouTube video editor, even if you never buy an add-on. Some of the more advanced capabilities like chroma key and picture-in-picture will cost you, but they're decently priced. HitFilm has lots of features any YouTuber will love. Many features must be purchased through add-ons. Large setup file might take a while to download.
