What is Gemini Omni 1.1 Flash?

Gemini Omni 1.1 Flash is Google's update to Gemini Omni Flash, announced on August 27, 2026. It adds the production controls creators need for more precise scenes: first/last-frame keyframes, a short reference-video input, and 4K upscaling.

Muapi wraps the update as focused text-to-video and image-to-video endpoints. The text endpoint accepts multimodal references and reusable profiles; the image endpoint controls a transition between first and last frames.

What's new in 1.1

First/last-frame keyframes

Specify a start and end frame to guide a continuous, controlled transition between two shots.

4K upscaling

Move approved 720p or 1080p work toward 4K final delivery when the project is ready to ship.

Video reference input

Use a short reference-video window to carry style and motion continuity into a new scene.

Native synchronized audio

Retain Gemini Omni Flash's native dialogue, ambient sound, and music generation in the same pass.

Focused endpoints

Use text-to-video for multimodal references and image-to-video for first/last-frame keyframe control.

Gemini Omni 1.1 Flash use cases

Keyframed transitions

Anchor first and last frames for precise, controllable movement between two shots.

Style-consistent sequels

Reference a short existing clip to keep a new scene visually and tonally aligned.

Consistent characters and voices

Layer saved character and voice profiles onto multimodal prompts for recurring-cast scenes.

Multimodal narrative shorts

Drive scene composition, camera direction, and dialogue from one rich prompt with native audio.

Final delivery at 4K

Upscale a reviewed draft for broadcast, streaming, or high-resolution campaign delivery.

Gemini Omni 1.1 Flash FAQ

What is Gemini Omni 1.1 Flash?

It is Google's August 27, 2026 update to Gemini Omni Flash, adding first/last-frame keyframes, a short reference-video input, and 4K upscaling through Muapi endpoints.

How is 1.1 different from the original Gemini Omni Flash?

The 1.1 update adds keyframe-controlled generation, a reference-video input for continuity, and 4K upscaling while keeping native synchronized audio.

Can I combine keyframes with a reference video or images?

No. Keyframe generation uses the image-to-video endpoint with a prompt, first_frame_url, and optional last_frame_url. Reference images, a video reference, voice profiles, and character IDs belong on the separate text-to-video endpoint.
