Food truck weekly special clip: Gemini Omni Flash 1.1, vertical, sound

A food truck can make a weekly special clip by sending a dish photo and a short prompt to POST /v1/videos with model: "gemini-omni-flash-1.1". Sume lists this model at 3 to 10 seconds, in 16:9 or 9:16, at 360p, 720p, 1080p or 4K, with native synced audio, so a sizzle comes with the picture.

That sound is the point for food. A silent clip of a burger is a photo that moves; a clip with a sizzle and a crunch is closer to a story-ready ad.

What the model is good for

Sume's docs give a 3 to 10 second window, and say this model accepts image and video references but not audio references.

Ten seconds is long enough for one dish: the plating, a steam shot, the box closing. If you need a longer menu reel, make several clips and cut them together.

The request

Send the dish photo as an input_references entry and describe sound in the prompt. Use 9:16 for stories and reels. Keep resolution at 720p while you iterate, and move up only for the take you will post.

Do not promise the dish looks exactly like the clip. The photo is a guide, and the generated food may differ in garnish or portion, so check it against what you actually sell.

Poll, download, and add the words

The job is asynchronous. Poll the polling_url until completed and download unsigned_urls[0]. A completed video has its own audio track, so check the volume and any generated speech before you post.

For the special's name and price, add text yourself or burn captions onto the clip with Sume's video-captions route. Captions work from audible speech, and a silent clip fails with caption_no_speech; for authored overlay text without speech, send cues with text, start and end.

Keep it truthful

Use the clip for atmosphere and the real photo for the menu. If the clip shows an ingredient you do not serve, an allergen claim that is untrue, or a portion bigger than yours, it is a bad ad even if it looks good. Re-run with a tighter prompt rather than posting a close miss.
