Video editor without a required account: Movavi Video Editor
If the whole account requirement is a dealbreaker, you have a genuine alternative. Not every editor gates you behind a login the way Microsoft Clipchamp now does. Movavi Video Editor is a desktop app for Windows and Mac that you can download and start using without creating an account first.
Because it's installed software rather than a cloud service, there's no mandatory sign-in just to open the timeline. You download the program, accept the license agreement, choose an install location, and you're editing. A Movavi account only becomes relevant for managing purchases and activation keys, not for basic access, which is a very different model from Clipchamp's login-first approach.
What you get is a beginner-friendly but capable editor: cutting and cropping, transitions, titles, filters, color correction, audio tools, and one-click AI features like automatic subtitles, noise removal and background removal. It's aimed squarely at the same audience Clipchamp courts, people making vlogs, social clips and family movies without wanting a steep learning curve.
Which matters more depends on you. If you're happy to trade an account for a fully free browser tool, Clipchamp is hard to beat, especially since it's free with Microsoft account access already built into Windows. If avoiding a mandatory login is your priority and you don't mind a trial's limits (or eventually paying), Movavi removes that friction entirely.
