What is Gemini Omni 1.2 Flash?
Gemini Omni 1.2 Flash (gemini-omni-1.2-flash-ext) is a unified multimodal video model engineered for fast iteration from draft 360p previews all the way to crisp 4K deliverables. Instead of switching tools between generation, character consistency, post-production restyling, and shot continuation, one model covers all five workflows.
It supports text-to-video (3–15s), image-to-video with a first frame and optional last frame, multi-image reference using up to 10 images to lock subjects or style, video editing to restyle or alter existing footage, and video extension to continue an uploaded clip seamlessly.
On Flux1 AI, every workflow runs directly in the browser on your shared credit balance alongside Wan 3.0, MiniMax H3, Grok Imagine 1.5, and Veo 3. Outputs render at 24 fps MP4 with synced audio, and failed runs are refunded automatically.

What Gemini Omni 1.2 Flash does well
Built for creators who want one workspace for drafting, framing, consistency, and shot finishing.
Five multimodal video workflows
Switch effortlessly between pure text prompts, first-frame animation, start-to-end transitions, 10-image reference guidance, video editing, and clip extension without changing pages.
Multi-image consistency up to 10 photos
Upload up to 10 reference photos of characters, wardrobe, products, or environments so lighting, identity, and visual style carry consistently across shots.
Video edit & extend from real footage
Drop in a clip up to 15 seconds to change outfits, lighting, weather, or props in Edit mode, or seamlessly add 3–10 new seconds in Extend mode—paying only for the newly added seconds when extending.
Flexible quality tiers from 360p to 4K
Test ideas rapidly at 360p (5 credits/s) or 720p (7 credits/s), step up to 1080p (8 credits/s) for social and web campaigns, or export master-grade 4K (16 credits/s).

Good to know
Key mode constraints and billing rules so there are no surprises.
Duration limits vary by mode
Text-to-video, first-frame image-to-video, and multi-image reference support 3–15 seconds. Adding a last frame or choosing Video Extend caps output duration at 3–10 seconds.
Video Edit vs Extend billing
Video Extend bills only the 3–10 newly generated seconds. Video Edit matches your uploaded source clip (up to 15 s) and bills by rounded source duration (max(1, ceil(seconds - 0.15))).
Mutually exclusive media inputs
Multi-image reference uses 1–10 photos and cannot be combined with a video file, while Edit and Extend take a single MP4/MOV/WebM clip (up to 15 s, max 50 MB here) without image inputs.
Aspect ratios & audio notes
Supported output ratios are 16:9 and 9:16. Most outputs include synchronized AAC audio; occasional 4K renders may arrive silent depending on upstream synthesis.
Gemini Omni 1.2 Flash FAQ
How much does Gemini Omni 1.2 Flash cost?
It costs 5 credits/s at 360p, 7 credits/s at 720p, 8 credits/s at 1080p, and 16 credits/s at 4K. A 5-second 720p clip costs 35 credits, and a 3-second 360p test clip costs 15 credits.
What modes does Gemini Omni 1.2 Flash support?
Five modes in one tool: Text-to-Video, Image-to-Video (first frame with optional last frame), Multi-Image Reference (1–10 images), Video Edit (restyle or change elements in an uploaded clip), and Video Extend (seamlessly continue an uploaded clip).
How does billing work for Video Extend vs Video Edit?
In Extend mode you only pay for the 3–10 new seconds you ask to add—the source clip is not billed. In Edit mode there is no duration slider because the output preserves the source clip length (up to 15 s), billed per rounded source second.
Why does adding a last frame lower max duration to 10 seconds?
First-and-last frame interpolation constrains both endpoints of the shot, which upstream supports for 3–10 seconds (single first-frame animation still allows up to 15 seconds).
What resolutions and aspect ratios are available?
You can render in 360p, 720p, 1080p, or 4K, in either 16:9 widescreen or 9:16 vertical, exported as 24 fps H.264 MP4.
What happens if a generation fails or is blocked?
All credits consumed for that job are automatically restored to your account whenever moderation rejects a task or an upstream job fails.
