Per-generation credit cost (open question)
Google has not published a per-generation credit cost for Omni Flash inside Google Flow. The best available signals as of 2026-05-29:
- Our own testing (Cited, 2026-05-28): a fresh 10-second 16:9 generation cost 30 credits. A single conversational edit on the same clip cost 40 credits — i.e., editing is 33% more expensive than re-generating from scratch. 🟡
- WaveSpeed's launch coverage reports a 4-second fresh clip at 15 credits plus 40 for an edit — different generation cost, same edit cost. Could be a shorter-clip discount, or pricing has shifted since. 🟡
- Google's only verified pricing signal is the existing Ultra tier including 12,500 monthly AI credits — confirming credits are the shared currency, but Omni's per-call rate is not officially listed.
Practical takeaway: if your generation didn't produce what you wanted, re-generate, don't edit. Editing burns more credits and frequently produces output that's visually indistinguishable from the original.
Where to use it
- Gemini app — primary interface; requires paid AI plan.
- Google Flow at labs.google/flow — full workspace with timeline + conversational editing.
- YouTube Shorts / YouTube Create App — free Omni Flash access, 18+.
- API for developers / enterprise — promised "in coming weeks" at launch (2026-05-19); not generally available as of 2026-05-29.
The base formula
Most working Gemini Omni prompts follow this structure:
[Subject] + [Action] + [Setting] + [Camera] + [Lighting] + [Style] Example: "A red panda chef tossing pizza dough, in a cozy mountain kitchen, low-angle close-up, warm tungsten light, Pixar-style 3D animation".
This is the same DNA as Sora / Veo prompts, but Omni adds two unique elements that most other models don't have:
- The "
@username" character summon syntax (for Avatar feature) - The conversational editing chain ("now change X, keep Y identical")
The opening-line trick
Lock these three things in the very first sentence:
Create a [duration]-second [aspect-ratio] [genre] video in one continuous shot. Why: Omni interprets "one continuous shot" as "no cuts" and respects the time / aspect ratio you specify upfront. Specifying these inline beats putting them in metadata.
Camera vocabulary Omni understands
From DeepMind's prompt guide, these terms are explicitly parsed:
Camera motion verbs
- Push: push in / punch in / dolly zoom
- Pull: pull-back / pull-up / pull-down
- Reveal: ascend revealing / pull-back and rotate
- Orbit: orbit around / sweep around / circle
- Pan: pan left / pan right / vertical pan
- Static: locked off / fixed / oner / continuous shot
Style references
- natural smartphone zoom
- film camera (warm, slight grain)
- webcam style (compressed, slightly soft)
- handheld (micro-jitter, organic)
Duration sweet spots
| Goal | Best duration | Aspect ratio |
|---|---|---|
| Mood / cinematic | 8-10s | 16:9 or 2.39:1 |
| Product hero | 6-8s | 1:1 or 16:9 |
| Reels / TikTok / Shorts | 5-7s | 9:16 |
| Slow-motion impact | 5-6s | 1:1 or 16:9 |
| Timelapse | 10s (max) | 16:9 |
| Avatar talking head | 10s (max) | 16:9 or 9:16 |

The "Keep X identical" lock
When using conversational editing (Omni's flagship feature), every follow-up turn should explicitly list what to preserve. Pattern:
[Change instruction]. Keep [X, Y, Z] exactly the same. Without this lock, Omni may re-style the entire scene when you ask it to change one element — losing the consistency that's the whole point of conversational editing. (Documented by Atlas Cloud's hands-on testing.)
The trigger pattern (for VFX)
One of Omni's strongest patterns — used in Google's own viral demos (mirror-arm-transformation, bubble sculpture, origami ships):
[Base scene]. When [specific trigger action], [specific transformation]. Keep [list] identical. Example: "A woman reaches toward a mirror. When her fingertips touch the glass, make the mirror ripple like liquid and her arm turn to reflective mirror material. Keep the parlor and lighting identical."
"It's blocking my prompt" — the two bugs you need to keep straight
Since launch, the phrase "Gemini Omni is blocking my prompts" has been used to describe two completely different bugs. Mixing them up is the most common source of confusion in the community right now.
Bug A — The false-positive policy block (still unresolved as of 2026-05-29)
Omni rejects clearly harmless prompts (Cat walks between rabbits,
Change the background to night) with a generic "I can't generate that video" / "policy violation" message —
claiming a rule violation that doesn't exist. Widely reported from 2026-05-19 onward. Google VP Josh Woodward
acknowledged the issue publicly and said Google was investigating and collecting affected examples.
As of today, no fix has been announced; users are still posting fresh examples on the
Google AI Developers Forum 🟡.
For the full breakdown of what's a real policy vs. this bug, see our
deep dive on Bug A.
Bug B — The quota counting bug (fixed 2026-05-28)
Unrelated to the policy block — this was a billing bug where failed generations (including ones killed by Bug A) were still being deducted from your quota. On 2026-05-28, Woodward announced:
- Failed requests no longer count against quota.
- AI Ultra Omni allowance doubled.
- Gemini 3.1 Flash-Lite prompts now completely free.
- Pro per-prompt quota capped to prevent runaway consumption.

How to tell which one hit you
- You got a "policy violation" / "I can't generate that video" message on an obviously innocent prompt → Bug A. Don't rewrite the prompt 10 times — it's the bug. Try again later or rephrase slightly.
- Your quota dropped despite a failed / refused generation → Bug B. That should be fixed now; if you still see it, contact Google support with the request ID.
Known failure modes (be honest about these)
DeepMind's own model card explicitly lists these as "Known Limitations" 🟢 — so when you hit them, it's not a prompt-writing problem, it's a model boundary.
Text rendering
Any onscreen text — labels, signage, captions, brand logos — degrades. Avoid mentioning text overlays in your prompt. Verified by PixVerse hands-on.
Hand articulation
Hands holding objects, sign language, typing — fine articulation drifts. Frame to hide hands when possible, or accept some imperfection.
Multi-shot character consistency
Per Atlas Cloud's multi-turn review:
Omni scores 3/5 on character consistency across 4+ shots. Use @character_name
with a reference image for best results, and accept drift past shot 4.
Complex motion
Per digit.in's test: complex actions (dancing, gymnastics, instrument playing) show AI artifacts more than static shots. Simple actions (walking, standing, talking) work best.
Word count over 50
Per Seaart's analysis: prompts longer than ~50 words dilute focus and reduce output quality. Be specific but concise.
What NOT to do
- Don't write Veo-style adjective stacks — DeepMind explicitly says Omni "doesn't need to be as prescriptive as Veo". Natural language beats template formulas.
- Don't change multiple variables per turn — split into separate conversational turns.
- Don't reference copyrighted IPs by name — "Studio Ghibli style" is risky; "hand-painted watercolor animation" is safer.
- Don't use Veo / Sora-specific syntax — Omni parses some of it but optimizes for its own conversational style.
- Don't request hardware brand names ("shot on DJI Mavic Pro") — Omni doesn't parse camera brands; use motion verbs instead.
Avatar feature hard rules
- Age requirement: 18+
- Geography: NOT available in EEA / Switzerland / UK at launch
- Language: English only at launch (May 2026)
- Watermark: every video carries Google SynthID, non-optional, embedded in pixels
- Reference recording: clear eyes / nose / mouth, no sunglasses / masks / hats covering face, no other faces in background
