LumiCut supports all video formats that macOS can read, including MP4, MOV, M4V, and AVI. For best results, use H.264 or H.265 (HEVC) encoded videos.
Toggle on "Subtitles" in the right panel. The App uses WhisperKit (open-source) with CoreML models bundled in the app to transcribe your video's audio entirely on-device. No download or internet connection required. Choose from 7 caption styles: Classic, Bold Pop, Outline, Boxed, Karaoke, Neon, and Fill. You can also pick an animation style and accent color.
AI-Frame uses Apple's Vision framework to detect people in your video and automatically keeps them centered in the 9:16 crop. Enable it in the export settings panel. It works best with videos that have a clear subject.
AI Shorts analyzes your long-form video to automatically find the best 30-60 second clips. It uses face engagement detection, transcript analysis, and silence detection to score and select the most engaging moments. You can also enable filler word removal, hook text overlays, and end cards for each clip.
Multi-Format export renders your video to multiple aspect ratios in a single batch: 9:16 (vertical), 1:1 (square), 4:5 (Instagram portrait), and 16:9 (landscape). Each format is saved as a separate file.
No. All video processing, subtitle generation, and AI features run entirely on your device. No video, audio, or personal data is ever uploaded. See our Privacy Policy for full details.
