What broke (and the fix)
- Generation 1 (Veo 3.1 Lite, 10 credits) was usable, but the glass only cracked as the slice separated. Generation 2 — the shipped final — cracks visibly while the knife is still pressing in, which is the shot the prompt asks for.
- Honest audio caveat: the glass-crack ASMR sound could not be fully verified in remote playback. There is no speech and no music — consistent with the natural cutting sound the prompt requests — but check the fine crackle on headphones before relying on it.

Veo 3 ASMR Prompt — Glass Fruit Cutting (Vertical)
by MotionPrompts (own run)
Prompt
Banned list —Beat grid —Build method —Self-review —
Extreme macro close-up: a crystal-clear glass strawberry on a dark slate board. A chef's knife slowly slices through it with a crisp, satisfying glass-crack ASMR sound, the slice falling away to reveal sparkling glass segments inside. Studio lighting with sharp reflections and refractions, black background, ultra-detailed, photorealistic, no music, only the natural cutting sounds.

No project file to download — a text-to-video prompt has no code. The prompt above plus these settings is the whole recipe: paste it into Google Flow (or any Veo 3.1 surface), set the aspect, and generate.
The exact text pasted into Google Flow — no structure tags, no code; Veo generated the film from this one paragraph. This entry cost 20 Flow credits (2 × Veo 3.1 Lite generations); together with the dialogue entry it used the account's full 50-credit daily allowance.
