Turn Full Lectures Into Short Educational Clips Automatically
A 50-75 minute lecture contains a handful of moments students actually rewatch: the core concept explained clearly, the worked example, the exam hint. OpenClip finds those segments in the recording, crops them to vertical, and captions every word — producing study clips for students and promo clips for the course itself.
Scenario
Lecture capture is everywhere — universities record through their AV systems, online educators record through Zoom or a camera at the whiteboard — but the recordings are used almost exactly once, by students cramming before exams and scrubbing blindly for the one explanation they need. Educators sit on hundreds of hours of this material while simultaneously needing short-form content for two very different jobs: study clips that help enrolled students review specific concepts, and promotional clips that show prospective students what the teaching actually feels like. OpenClip serves both from the same upload. The AI transcribes the full lecture, identifies the segments with the highest standalone value — definitions delivered cleanly, worked examples with a beginning and end, the moments where the lecturer says 'this is the key idea' — and cuts them into clips. Word-level captions handle the technical vocabulary that auto-captions elsewhere routinely mangle, and the transcript is reviewable so a TA can fix a domain term once and keep the timing intact. Vertical export means the same explanation that lived in a learning management system can recruit new students on TikTok and Shorts, where study-content audiences are enormous.
Workflow
Upload the lecture recording
Drop in the lecture capture file, Zoom recording, or camera footage — full 50-75 minute sessions as-is. Weekly uploads through a semester build a clip library alongside the course.
AI transcribes with word-level timing
The complete lecture becomes a searchable, reviewable transcript. Technical terms can be corrected once in text and every affected caption updates in sync.
Detection finds teachable standalone moments
The AI surfaces segments that work out of context: crisp definitions, complete worked examples, big-picture explanations, and the emphasized takeaways students rewind for.
Clips crop to vertical with the lecturer framed
Face tracking keeps the lecturer centered as they move at the board or podium, converting a static wide classroom shot into a clean 9:16 clip.
Export study clips and promo clips
Publish concept clips to the course site or LMS for revision, and post the most engaging moments to TikTok, Reels, and Shorts as recruitment content for the course.

Features
Key-Concept Moment Detection
The AI surfaces the segments students rewatch: clean definitions, complete worked examples, and the explicitly flagged 'this will be on the exam' moments.
Captions Built for Technical Speech
Word-level captions with a reviewable transcript — correct a domain term once and the timing stays perfect. Essential for STEM, medical, and legal material.
Whiteboard-Aware Framing
Face tracking follows the lecturer as they move between podium and board, keeping the vertical crop centered on the person teaching.
Accessibility by Default
Every clip carries burned-in captions, supporting deaf and hard-of-hearing students and meeting accessibility expectations without separate workflows.
Study Library + Promo Feed
The same detection pass produces LMS-ready concept clips for enrolled students and scroll-stopping promo clips for prospective ones.
Vertical Export for EduTok
Educational content is one of short-form's biggest categories. Clips export 9:16 and captioned for TikTok, Reels, and Shorts, where study audiences already are.
