Mastershot Studio is a video editor that runs in your browser. Trim and split clips, add text, transitions, music and a voiceover, and export an MP4 in up to 4K with no watermark. Your files open straight from your disk and are never uploaded. The AI tools run on your computer too: automatic subtitles, background removal without a green screen, Magic Cut for pauses and ums, clean audio and blur faces. It's all free, with no credits and no length limit.
