One twilight exterior photo is enough for a 6-second vertical open-house clip at $0.75 on Sume: Gemini Omni Flash 1.1 lists $0.10 per second at 720p, Sume bills the list price x 1.25 ($0.125 per second), and 6 seconds comes to $0.75. Ten listings are $7.50. Use the photo as the first frame so the house in the clip is the house in the photo.

A listing clip has one rule that other ads do not: it must not change the property. Animate light and weather around the home, not the home. Do not add rooms, a bigger yard, a finished basement or a view that is not there.

What to animate and what to leave alone

The prompt should describe motion in the scene, never the building.

Call it

gemini-omni-flash-1.1 accepts 3 to 10 seconds and 16:9 or 9:16, with native synced audio that is always on. Ask for quiet ambient sound. The default resolution is 720p; the model also lists 1080p ($0.1875 per second billed, $1.13 for 6 seconds rounded up) and 4K.

Add the facts afterwards

The price, address, open-house time and the agent's contact belong in captions, not in the generated scene. Build them with Video captions cues, or lay a still plate over the clip with Timeline compose.

Before you post, watch the clip against the photo. If the generated frames add a feature that is not in the listing, reject the take.

  • Re-roll costs $0.75 each at 720p.
  • Keep a copy of the source photo with each clip for your records.
  • Check your local rules on virtual staging and altered images before you publish.
