How to Use Gemini Omni 1.2 Flash

Step 1 — write the shot, not a story

Gemini Omni 1.2 Flash takes a text prompt describing one shot. The prompts that land name four things: the subject, the action, the camera, and the light — "a red drone glides low over a rainy neon street, slow tracking shot, wet reflections".

Keep one action per clip. If the story needs a second beat, generate it as a second clip with the same references instead of packing two events into one prompt.

Step 2 — attach references when identity matters

Add up to seven reference images when a face, product, or world must stay consistent. Then tell the model what each image is for inside the prompt — "the woman from image one walks through the market in image two". Unnamed references still help, but named ones steer harder.

Step 3 — draft cheap, finish high

Start at 720p with a 4–6 second clip and iterate on the prompt until the motion and framing read right. Only then re-render the keeper at 1080p or 4K — you pay for polish once, not on every draft.
