Original Summary

Hi HN,<p>I built S-Roll, a macOS app for turning long-form video into clips entirely on-device.<p>Drop in podcasts, gameplay videos, or other long videos and get shorts or viral reels instantly.<p>You can chat with the video to find a specific moment and turn it directly into a clip. S-Roll also does subject tracking, so the person or object you care about stays in frame when converting to vertical video.<p>Everything runs locally on your Mac, including transcription and video understanding.<p>S-Roll: <a href="https:&#x2F;&#x2F;saliency.dev&#x2F;s-roll" rel="nofollow">https:&#x2F;&#x2F;saliency.dev&#x2F;s-roll</a><p>Discord: <a href="https:&#x2F;&#x2F;discord.gg&#x2F;B6HnneePm" rel="nofollow">https:&#x2F;&#x2F;discord.gg&#x2F;B6HnneePm</a><p>Would love feedback :)
