Emdash’s 1:28 launch film runs 54 scenes, about 1.6 s each. The product is on screen from the first frame and 9 features are revealed. The call to action lands at 1:16 (86% in), over a voiceover. The video opens with the two founders on a couch, then cuts to a fast screen-recording walkthrough of the dark Emdash interface, punctuated by zooms into controls, 3D window tilts and a small facecam inset, and closes with a couch call to action and an animated logo. Pacing is quick at about 44 cuts per minute, with white caption pills carrying the narration over a blurred nature wallpaper.

Footage neededEstimated needs: 10 capture groups — your screens or recordings · 1 official logo — reused across the film · 2 filmed passages — shoot, supply or replace · 5 graphic passages — draw or supply · 1 3D passage — build or supply
