Gemini Omni 1.2 Flash API for 15-Second Video with Native Audio
Gemini Omni 1.2 Flash generates and edits video with synchronized speech, music and sound effects from text, images and video. Google says it produces clips of up to 15 seconds, lets you refine the same clip over several conversational turns and keeps faces, products and brand colors consistent across shots. Output runs from 360p drafts to 4K upscales in 16:9 or 9:16.
What's New in Gemini Omni 1.2 Flash
Google released Gemini Omni 1.2 Flash on November 5, 2026, as an update to Gemini Omni 1.1 Flash. These are the changes Google describes.
Clips and Edits of Up to 15 Seconds
Generation and editing now run up to 15 seconds, up from 10 seconds with Gemini Omni 1.1 Flash, according to Google. You set the length from 3 to 15 seconds in one-second steps. The model is part of the Gemini Omni family of video models.
Multi-Turn Conversational Editing
Refine the same clip turn by turn instead of starting over: swap a product or background, or change the lighting, weather, camera angle or aspect ratio. Google says editing works across full 15-second clips.
Closer Reference Following
Google says the model keeps faces, garments, packaging typography, brand colors, products and characters consistent across shots and camera angles, with less visual drift or morphing in first/last-frame interpolation and clip extension.
Native Audio, Dialogue and Lip-Sync
Every clip can carry synchronized speech, music and sound effects. Google says dialogue sounds more natural, lip-sync is clearer and the model keeps multiple speakers distinct.
Camera Moves and Multi-Shot Sequences
According to Google, FPV flythroughs, zoom-outs and orbits now run with fewer unwanted jump cuts than in 1.1 Flash. Google's own demo builds a four-shot, 15-second explainer from a single style frame.
Draft at Low Resolution, Upscale the Best Take
Output resolutions are 360p, 720p, 1080p and 4K. Google's recommended workflow is to draft at 360p or 720p, then upscale the chosen take to 1080p or 4K.

How to Work With Gemini Omni 1.2 Flash
This workflow for Gemini Omni 1.2 video generation follows Google's draft-then-upscale guidance and the model's published features.
- 1
Step 1: Draft at 360p or 720p
Generate several short low-resolution takes from a text prompt, a style frame or reference images, and choose the one with the right composition and motion.
- 2
Step 2: Lock Your References
Add product shots, character images or packaging (up to 6 reference images) to your prompts so faces, typography and brand colors stay consistent across shots and drafts.
- 3
Step 3: Refine in Conversational Turns
Edit the chosen clip turn by turn: change the background, lighting, weather or camera angle, or switch between 16:9 and 9:16, without regenerating from scratch.
- ✓
Step 4: Render the Final Take
Set resolution to 1080p or 4k for the final render, or pass the chosen clip of up to 15 seconds in video_list to refine it with an edit.
