Summary
Turn one long video, podcast or webinar into a week of vertical shorts — how to find the best moments, reframe to 9:16 and caption them for TikTok and Reels.
Every long video is a goldmine of shorts. A single 30-minute podcast or webinar can yield ten vertical clips — a week of daily posting from one recording. Here is how to mine it.
Find the moments worth clipping
The best short-form moments share a shape: a strong claim, a surprising fact, a tight story, or a clear how-to. Skim for spikes in energy and self-contained ideas. AI clip detection scores transcript segments for "virality" so you do not have to scrub the whole thing.
Reframe to vertical without ruining it
Landscape footage must be reframed to 9:16, keeping the subject centered. Smart cropping tracks the action so faces and key visuals stay in frame instead of being chopped off.
Caption for silent viewing
Add word-by-word animated captions. On TikTok and Reels, captions are not optional — they are the retention mechanism.
Title each clip as its own video
A clip is not a leftover; it is a standalone video. Give each one a hook title and SEO description. Ten clips means ten more chances to be discovered.
