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.
S-Roll is an AI-powered video editing tool for iOS that automatically identifies and clips segments from long videos based on user descriptions. It processes all data locally on Mac devices, ensuring privacy for videos and transcripts.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
