Does it cut videos with no talking?

Yes. Videos with sound or music but no talking (try-ons, unboxings, product shots) are cut by what's on screen. The getting ready at the start and end comes out, and long still moments can too; the video keeps its sound, and anything you say is kept. If getting ready is most of the video (a get-ready-with-me), or the product is on screen for under 5 seconds, the getting ready stays. It's labelled “Cut as B-roll”.
