Gemini Omni reference clips: 3 videos, 3 seconds each, VIDEO_REF_0

Reference-to-video on Gemini Omni Flash 1.1 is how you ask for a new clip that borrows a look, a person or a motion from material you already have. The limits are tight and specific, and the prompt needs to name each reference by position.

The limits

Sume documents the 3-second limit and its request schema repeats it. Trim longer clips before you send them.

Address references in the prompt

References are 0-based and numbered in list order within each kind. Write <IMAGE_REF_0> for the first image and <VIDEO_REF_0> for the first clip. A single reference image with no frame field is reference-to-video, not image-to-video; use image_url when you mean a first frame.

What it costs

The docs bill Omni by output second at list times 1.25 as a function of resolution, and describe no separate reference charge. An 8-second 720p clip is $1.00; a 10-second one is $1.25. Audio is always on and cannot be switched off, and there is no reference_audio_urls field on this model.
