There is no one button for this yet, but there is a stack the community has settled on. The trick is to let AI find the good moments from the transcript, then cut and caption with a normal editor.

The open problem is still B-roll: no tool reliably fills a talking-head clip with supporting footage yet, so keep clips simple for now.
The full roster and the latest notes are on the community wiki: Video Creation and Video Editing Tools.
Discussions are coming soon. Every skill, app, and guide will carry its own thread where shluchim compare notes on what worked.
