for Startups Hasan Minhaj's 54-minute interview with Neil deGrasse Tyson, start to finish. The agent recognized both voices and tracked them through all 18 topics they covered before it made a single cut.

A real run. Waveform and topics come from the episode itself. Clip positions are matched to the source audio. Speaker colours are estimated.
Crop, follow or stack. StarZero's proprietary video understanding model determines who is speaking, how many cameras there are and what is on screen, and frames every moment to match. Every reframing shown on this page is from a real edit using real data.

Write on the clip the way you would on a Frame.io review, press Send, and the new version comes back.
