You can use free video editing software to add subtitles, create a DVD menu, merge video files, extract or add audio, add special effects, and cut out parts of the video. Most vloggers need some kind of video editor.

Since most free video editors limit their features to promote their professional versions, you may encounter obstacles that prevent you from making advanced edits. For editors with more advanced features that aren’t free, you’re best off looking at mid-level digital video software or the best professional video editing programs.

iMovie is free for macOS users. It offers many basic options for editing video and audio, plus adding photos, music, and commentary to your videos. It's easy for beginners to use.

While more advanced editing features are limited, one of iMovie's best features is the ability to create movies in 4K resolution. You can even start editing on your iPhone or iPad and then finish it on your Mac.
