Gemini Omni 1.2 is the third version of Google's video model, after Gemini Omni and Gemini Omni 1.1. The biggest change for your budget: you pay per second of video instead of a flat rate per job. Length is set in one-second steps from 3 to 15 s (previously 4-10 s), resolution from 360p to 4K. Every clip comes with sound. Aspect ratios: 16:9 or 9:16.

There are more inputs than in 1.1: text only, a photo as the first frame, a start-end frame pair, or up to 10 reference images (1.1 took 1 or 3). The vendor also has edit and extend modes for an existing clip, which Jantaris does not expose yet.

Best for

  • Cheap 360p drafts - here that tier really costs less, unlike in 1.1
  • Transitions between two frames (first and last frame)
  • Scenes with several characters or products from reference images
  • Longer shots up to 15 s in 4K

How to write prompts

  • Check the composition at 360p in a short clip, then raise resolution and length.
  • Frame pair: image_url is the start, end_image_url the end. Do not combine it with image_urls.
  • Describe the sound: ambience, steps, background music - the model always generates audio.
  • Leave on-screen text out.
