Shortshort is an AI video editing web app that turns long-form videos into short, vertical clips for social media and digital content. Upload podcasts, webinars, online courses, interviews, livestreams, talks, sales calls, or other recordings, and Shortshort identifies complete, quotable moments that can be converted into concise video shorts.
The platform transcribes video content word by word, selects relevant passages, reframes footage into a 9:16 vertical format, and follows the active speaker using face and scene tracking. It also generates synchronized captions in four styles: Spotlight, Impact, Karaoke, and Minimal. Users can choose the number and target duration of clips, adjust framing keyframes, and export individual shorts as MP4 files in 1080 × 1920 resolution.
Shortshort supports MP4, MOV, and WebM uploads of up to three hours and 2 GB. It is designed for content repurposing, helping creators, marketers, educators, speakers, and sales teams transform existing long-form video into captioned short-form content for platforms such as YouTube Shorts, TikTok, and Instagram Reels. Exported videos are organized in the My Projects area, while the platform also provides a community gallery for sharing published shorts.
