xAI’s 0:31 launch film runs 6 scenes, about 5.3 s each. The product is on screen from the first frame and 2 features are revealed. The call to action lands at 0:26 (82% in), over a voiceover. The video holds on a single black field, letting white type slide in, hold, and dim while one fluid red sphere and a dark two-card audio UI carry the visuals. Pacing is slow and even at about 108 bpm, with word-by-word transcript typing and the orange highlight swapping between ORIGINAL and CLONED as the signature moves.

SpaceX Super Intelligence - Voice Cloning is now live via the xAI API! Create a custom voice in, scene by scene
· 6 scenes as text
01 · Product intro · 0:00–0:04
On black, the white headline slides in from the left, holds, then fades out. A glowing red and white fluid sphere, a voice waveform, rises from the bottom edge, settles at center and keeps undulating.
On-screen text: “Clone your voice with Grok API”
Techniques: Kinetic type
Camera: Pan
02 · Feature reveal · 0:04–0:22
A dark panel holds two side-by-side audio cards, ORIGINAL and CLONED, each with a waveform and play/stop button; the active one glows orange. A red smoke wisp fades from the top as a caption line types the call transcript word by word while the orange highlight swaps between cards.
On-screen text: “Nice to meet you, Jane. How can I help?”, “Okay, let me make sure that I got that right.”, “Is that [email protected]?”, “Is that spelled J A N E dot D O E at Gmail dot com?”, “Let me go ahead and send an authentication code to that email, one sec.”
Techniques: Kinetic type
Camera: Pan
03 · Feature reveal · 0:22–0:23
A dark voice-cloning UI with original and cloned cards plus a transcript line fades to black as a large white headline slides up from the bottom into the center.
On-screen text: “Or use our catalog of over 80 voices”
Techniques: Kinetic type
Camera: Pan
04 · Feature reveal · 0:23–0:26
A white sans-serif line, “Or use our catalog of over 80 voices”, slides in and holds on a black field. It then gives way to a centered sign-off: “Available now” above the URL x.ai/news/grok-custom-voices.

05 · CTA · 0:26–0:28
Two lines of white text hold centered on a black field: a short headline above a long URL. The frame stays locked and still, then the type dims to a dark gray as the scene closes.
On-screen text: “Available now”, “x.ai/news/grok-custom-voices”
Camera: Static
06 · Outro · 0:28–0:31
The white Grok symbol and wordmark fade in at the center of a black field and hold still as the closing sign-off. The caption “Available now” and the URL x.ai/news/grok-custom-voices complete the lockup.
