About S-Roll

S-Roll is a desktop application for macOS that converts long videos into shorter, shareable clips using local AI processing. Users upload a video file and the tool automatically transcribes the content, identifies self-contained sections, and generates clips in vertical, square, or wide formats. The application scores clips and presents them with titles and summaries for review. Users can search clips using natural language queries, apply subject tracking to maintain focus on moving subjects, and edit clips in a built-in editor to trim, adjust framing, and style captions before exporting as MP4 files. All processing occurs locally on Apple silicon Macs running macOS 26 or later, with no internet required after initial setup. The tool emphasizes privacy by keeping videos, transcripts, and project data on the user’s device.
