Command · Create Shorts

shorts.create

Makes one new sequence per short (from shorts.find): the range cut out of the source sequence, reframed to 9:16 (or "aspect") with editable keyframes following the speaker, captioned, with the title as a hook for its first seconds; optionally cleaned of fillers and silences and normalised to -14 LUFS.
