What they did
Brooke Lacey, who has more than 290,000 TikTok followers and used to cut every video by hand, walked Claire Vo through her editing setup on the How I AI show. She drops a raw video shot on her phone onto her computer and Claude Code runs the edit chain: Whisper transcribes the speech and FFmpeg makes the jump cuts. She taught Claude her own cutting rhythm, how she likes hooks to open and what she finds funny, and keeps notes and status files it works from. She also has it go through her TikTok comments to find ideas for the next scripts.
How it went
On the show Claude edited a video live, and she says a typical edit takes about 15 seconds. She now posts about once a week with no editor and says her audience keeps growing. She also covers the times Claude lets her down and how she steers it back with her status files and follow-up prompts. The episode notes give no figures on cost or error rate.
Worth knowing
The speed comes from the style notes she wrote, not from a single prompt: the cadence, hook and humour rules had to be taught. This is an interview summary from a podcast, so the details of the edit chain are in the episode rather than in writing. FFmpeg and Whisper both run locally on her machine.
