Real estate agent intro clip: headshot, logo and listing photos

For a branded real estate intro, put the agent's headshot, the brokerage logo and two or three listing photos into reference_image_urls on gemini-omni-flash-1.1, and refer to each as <IMAGE_REF_0>, <IMAGE_REF_1> and so on in the prompt. The index follows your list order, starting at 0. You get a 3 to 10 second clip with native audio.

Do not rely on the model to draw a logo or an address. Overlay the real logo and address afterward. Source: Video Router, read 2026-10-04.

Reference order

Order the references so the prompt reads naturally. The tag numbers below are the ones to use in the example.

Request

Use the headshot only with the agent's consent, and keep the property photos honest. A generated move through a room is an interpretation, so avoid prompts that add features the house does not have.

Add the real details

Add the address, price and phone number with Timeline compose in overlay mode: a still plate over your clip at a position you choose, a flat $0.02 per job. For spoken-word captions, POST /v1/video-captions is $0.20 for a clip up to 60 seconds, and a clip with no speech needs cues.

References are guidance, not frames

Plain image_to_video is the better route when you want the actual photo as the first frame. Reference-to-video treats images as guidance and does not promise to reproduce them exactly.
