An agentic harness that turns long videos into clips
S-Roll is a fully local agentic harness for video understanding. Open a podcast, gameplay recording, interview, or talk and describe the moment you want. S-Roll finds the footage, creates clips, suggests highlights, tracks subjects, and provides an editor for trimming, reframing, captions, titles, and export. All AI processing runs on your Mac, so videos, transcripts, and chats stay there. Free on the Mac App Store with no watermark.
