Shizuku AI’s 2:04 launch film runs 12 scenes, about 10 s each. The product is on screen from the first frame and 5 features are revealed. There is no explicit call to action; a voiceover carries the film. The video opens on a title card, then runs one continuous voice conversation with the avatar, splitting it into labeled feature callouts (Backchannels, Turn-taking, Barge-in, Tools) laid out as a two-column panel with live waveforms and typed chat bubbles, and closes on a black logo card. Pacing is slow and steady at about half a cut per minute, with long takes, typewriter text, popping status pills, and sliding phone mockups as the main transitions.
No filming indicatedEstimated needs: 5 capture groups — your screens or recordings · 1 official logo — reused across the film · 2 graphic passages — draw or supply · 3 3D passages — build or supply

A white-haired anime avatar talks and gestures on the right over a blue starry background. A left panel shows User and Shizuku waveforms filling in; when the user cuts in, a pink Both talking badge and red marker appear and Shizuku's waveform stops. Subtitles type out the exchange.
On-screen text: “Barge-in”, “Stops when you cut in”, “User My mom's birthday is next week. What do you think I should get her?”, “Shizuku Hmm, maybe start by thinking about her hobbies and the things she likes.”, “User Oh, wait, wait. My budget's about 3,000 yen, and my mom isn't really into flowers.”, “Shizuku Got it. Around 3,000 yen, and no flowers.”
