Which Gemini Omni Flash mode to use
Gemini Omni Flash has 3 modes. Pick by what you already have.

| Image → Video | A first frame, optionally a last frame, and a prompt | Bringing a picture you already have to life: a product shot, a character, an artwork. With a last frame: transitions and loops. | $0.089/s |
| Reference → Video | Up to 6 images, and a prompt | Keeping a character, product or style consistent, or matching a clip's motion or a sound. | $0.089/s |
Step by step
How to use Gemini Omni Flash in 6 steps
- 1
Open Gemini Omni Flash in the Studio
Open the Studio (it opens with Gemini Omni Flash selected), or choose the Video tab and pick Gemini Omni Flash in the model menu. Sign in with Google or your email; you pay per generation from prepaid credits.
- 2
Choose what to make
- Text → Video — a prompt.
- Image → Video — a first frame, optionally a last frame, and a prompt. Add it under “First frame” (and “Last frame” for a transition).
- Reference → Video — up to 6 images, and a prompt.
In reference mode, refer to each upload in the prompt by its tag — @Image1 — and say what to take from it.
- 3
Write the prompt
One shot per prompt works best. Cover these, in plain sentences:
- Subject. Who or what is on screen, with the details that must stay consistent: age, clothing, materials, colours.
- Action. One clear action in the present tense. For clips up to 10 s, describe a short sequence of beats.
- Camera. Shot size and movement: close-up, wide, dolly-in, orbit, handheld, drone.
- Scene and light. Location, time of day, and where the light comes from.
- Style. Lens, film look, colour grade or animation style.
- References. Say what each reference controls, e.g. @Image1: “@Image1 is the main character”.

The settings sit under the prompt; rarely needed ones are behind ⋯. What each does — and to the price — is in the table below.

Generate
The exact price is shown before you run: press Generate (or ⌘/Ctrl + Enter). The amount is held from your balance and refunded in full if the generation fails.

Download and iterate
Results appear above the prompt; download them from there. Change one thing per try — the prompt, the camera move or a setting — so you know what helped. Compare runs the same prompt on several models side by side, and Code shows the same request for the API.

Common Gemini Omni Flash mistakes
Expecting one long take
One generation is up to 10 seconds (4, 6, 8, 10 s). Plan longer pieces as several shots, and keep the subject consistent with the same reference images in each.
Several actions in one prompt
Give each clip one clear action and one camera move. A list of events in one prompt usually gets merged or skipped.
References the prompt doesn't name
Refer to each upload by its tag — @Image1, @Video1, @Audio1 — and say what to take from it (the face, the outfit, the camera move, the voice).
Describing what you don't want
Prompts work better when they describe what should be on screen. "No blur" or "no extra fingers" can pull the result towards the very thing you name.
