The taxi ad: every prompt, free

A 20-second ad made with zero filming. One image-to-video prompt on Seedance 2.5 in Higgsfield (30 seconds, 9:16, 720p, one reference photo for the look), then cut and captioned locally in Diffusion Studio. Two renders, 390 credits in total. The person and the voice are AI-generated.

The Seedance 2.5 prompt

Vertical 9:16 phone-shot creator video, 30 seconds, night, back seat of a yellow taxi in a rain-wet city, neon bokeh sliding past the windows.

@image1 = the creator's look only: young woman, mid-20s, fair skin, dark wavy shoulder-length bob with violet-blue underlights, dark plum lipstick, small hoop earrings, silver chainmail halter dress under an open black leather jacket. Hold this look in every shot.
Editing: fast creator-ad rhythm, a hard cut every 2 to 4 seconds, handheld phone energy, exaggerated 3D moments (the frozen coffee splash, the screen lifting off the laptop).

Shot 1: Low angle from the seat as the taxi door swings open; she drops into the back seat with a coffee cup and a phone at her ear, breathless. Camera: handheld push-in to a medium close-up. She says "This is me, thirty seconds before the biggest pitch of my life."
Shot 2: Top-down over her lap; the coffee cup tips and the splash freezes mid-air for a beat, then she flips open a laptop showing a plain pitch deck titled only "PITCH" with three empty image boxes; no brand names or logos on screen. Camera: locked overhead. She says "The client said yes today, and I have zero visuals."
Shot 3: The laptop screen lifts off the keyboard and unfolds into floating glass panels around the cabin: a generic video-generation dashboard with model cards, clip thumbnails, a bright Generate button; no readable brand names or logos on screen. Camera: slow orbit around her head. She says "So I opened Higgs-field in the back of a taxi."
Shot 4: Rapid montage, one whip pan per beat: her fingers typing, a cinematic sports car rolling shot at golden hour appears on screen, then a perfume bottle macro with liquid ripples, then a sneaker landing in slow motion, city lights streaking past the window between each. She says "One prompt, one model, one minute per shot."
Shot 5: She spins the laptop toward the camera, grinning; the screen shows a finished grid of six polished clips. Camera: quick push-in to her face. She says "By the time the meter stopped, the deck was done."
Closing: She leans back, taps the rain-streaked window twice, looks straight into the lens in a held medium close-up for the final two seconds and says "Comment LOOP and I'll send you the prompts." Silence holds the final half second.

Voice: exactly one voice in the whole clip, hers, a young female voice, warm, confident, American accent, fast energetic delivery, slightly breathless in shots 1 and 2, playful and assured from shot 3. Realistic lip articulation, no exaggerated mouth opening, no head turns while speaking. No male voice, no second narrator, no voiceover other than her lines above.
Audio: tense low synth pulse and ticking percussion under shots 1 and 2, a riser into shot 3, then an upbeat driving electronic groove to the end; a hard whoosh on every cut, keyboard clicks and soft UI ticks in shots 3 and 4, a final chord on the closing. Dialogue clean and above the music, taxi cabin ambience subtle.
Look: crisp phone footage, shallow depth, warm tungsten cabin light against cool blue street neon, high contrast, film-like motion blur on the whip pans.
No subtitles, no on-screen text, no captions, no logos, no watermark.

How it was cut

Voice and music were split with demucs. Her lip-synced lines stayed with their own take; the off-camera lines came from the second take. Picture: intro, open the laptop, the floating-panel effect, the montage, the close-up. A 2-second zoom into the screen replaced the hard cut. Captions from a plain SRT file.

What did not work

A reference video for rhythm leaked its narrator and its on-screen text into the render. The brand name is still mispronounced by the model; spell it as two words or caption it.
