Static shots lose attention. Dynamic editing keeps it.
Watch retention data from high-performing YouTube and podcast video channels consistently shows the same thing: static, unchanging shots see faster drop-off than footage with dynamic camera movement or zoom variation — even when the content itself is identical.
The problem is that adding zoom variation manually is time-consuming. A 30-minute interview might need 80–120 individual zoom keyframe pairs to feel properly dynamic — each one requiring you to find the right moment, set the scale, ease the curves, and check the timing.
Auto-Zoom reads your audio for emphasis peaks — the moments where a speaker is making a point, raising their voice, or delivering something important — and places smooth zoom keyframes at exactly those moments. The footage becomes more engaging without a single manual keyframe.

Who it's built for
YouTube creators
Single-camera talking-head content is the most common format on YouTube and the one that benefits most from dynamic zoom variation. Auto-Zoom makes static footage feel professionally edited.
Podcast video editors
Interview footage recorded from a fixed position gets significantly more engaging with subtle zoom variation timed to conversational emphasis — without looking artificially edited.
Corporate video editors
Executive interviews, training content, and talking-head corporate videos benefit from dynamic zoom to hold attention across longer runtimes.
