Webinars are content goldmines—but only if people actually watch them. Over the last few years, I've tested countless workflows to repurpose long recordings into short clips that perform on TikTok, Reels, and YouTube Shorts. The rise of the AI tool for repurposing webinars into clips has changed everything: instead of scrubbing timelines for hours, we can now rely on long video repurposing AI to find highlights automatically.
In this article, I'll share my hands-on experience reviewing five tools that excel at AI powered long video summarization, smart clipping, and vertical formatting. If you're serious about scaling content, understanding how tools like CapCut long video to shorts fit into a modern workflow will save you time—and sanity.
Why AI Long-to-Short Tools Matter for Webinar Creators
- They unlock hidden value in long content. Webinars often run 60–180 minutes. A strong AI tool for repurposing webinars into clips can extract dozens of engaging moments, turning one recording into weeks of short-form content without starting from scratch.
- They reduce manual editing time. With AI powered long video summarization, the software analyzes speech, pacing, and engagement signals, replacing tedious timeline scrubbing with automated highlight detection that's surprisingly accurate.
- They improve discoverability across platforms. Shorts dominate feeds. Using a smart long video chapter creator, creators can publish focused clips that match platform algorithms and audience attention spans.
- They support consistent branding at scale. Templates, captions, and smart formatting ensure every clip looks on-brand, even when batch-generated by long video repurposing AI.
