Create a video from one prompt
Describe the whole video. We'll break it into short scenes, generate each clip with Gemini (Veo), then stitch them into one film.
Upload people, logos, products, places, etc. and describe them in your prompt (e.g. "the woman in the photo"). Omni uses them all; Veo uses the first 3 per clip.
Seamless composes one background music track that plays unbroken over the whole video (added when you click Stitch), so it never sounds stitched. Any narration you write in your prompt is spoken at the right moment — just include it, e.g. Narrator: "In the beginning…". No narration in the prompt → music only.
