ABOUT THE WORKFLOW

Generate a Video from a Prompt
Write a prompt describing the scene, action, camera movement, and sound. Gemini Omni Flash generates a video with native audio in a single pass. Pick your duration and aspect ratio, then download the MP4.

Partner node. This workflow calls an external API, so each run uses credits from your API wallet. No API key needed. Floyo handles the connection.

Model

• Gemini Omni Flash by Google. A multimodal video generation model built on the Gemini Omni architecture, grounded in real-world knowledge. Generates video with native audio, maintains character and object consistency, and supports conversational multi-turn editing.

HOW IT WORKS

Step 1. Write your prompt
Describe the full scene: subject, action, camera movement, lighting, mood, and sound. "A golden retriever runs through a sunlit meadow toward the camera, wildflowers swaying, bees buzzing, warm afternoon light, shallow depth of field" gives the model clear direction.
Works great with: cinematic scenes · product reveals · nature footage · character action · social content

Step 2. Set duration and aspect ratio
Duration defaults to 8 seconds. Aspect ratio defaults to 16:9 widescreen. Switch to 9:16 for vertical or 1:1 for square.

Step 3. Hit run and download
Gemini Omni Flash generates the video with synchronized audio and returns an MP4 at 30fps.
Ready for: Premiere · DaVinci Resolve · After Effects · TikTok · Instagram · YouTube

First time? Write a detailed prompt and hit run. Leave duration and aspect ratio as-is.

RECOMMENDED SETTINGS

Quick-start guide. Find the goal that matches yours and copy the settings.

• Standard video from text — 8 seconds, 16:9, safety checker off. Write your prompt and run.

• Vertical for social media — Switch aspect ratio to 9:16. Native portrait output for TikTok, Reels, and Shorts.

• Shorter clip — Lower duration to 4 or 5 seconds. Faster generation, lower cost. Good for hooks and teasers.

• Audio not matching the scene — Add explicit sound descriptions in the prompt. "Waves crashing, seagulls calling, wind in the grass" steers the generated audio.

• Motion looks stiff or generic — Use cinematic camera terms: "slow dolly push-in," "handheld tracking shot," "low-angle crane rising." The model follows camera language.

• Scene lacks detail — Write a longer prompt. Describe materials, light direction, color temperature, and spatial relationships. Gemini Omni Flash is grounded in real-world knowledge, so specific scene descriptions produce more accurate results.

Prompt: Structure it as subject, action, camera, lighting, then sound. "Close-up of hands shaping clay on a pottery wheel, camera slowly orbits, warm studio light, soft instrumental music" is specific. "Cool video of pottery" is not.

WHAT WORKS BEST / WHAT TO AVOID

✅ Works great

• Detailed prompts with subject, action, camera, lighting, and sound

• Cinematic camera terms (dolly, tracking, pan, crane, orbit)

• Sound descriptions written directly in the prompt

• Moderate action with clear subjects and defined environments

⚠️ May produce softer results

• Very short prompts with no camera or lighting direction

• Extremely complex multi-character choreography

• Prompts with no sound or atmosphere description

• Requesting exact brand logos or copyrighted characters

FAQ

What is Gemini Omni Flash?
Gemini Omni Flash is Google's multimodal video generation and editing model, released June 30, 2026 alongside Nano Banana 2 Lite.

What is the difference between Gemini Omni Flash and Veo 3.1?
Veo 3.1 is optimized for generating single high-quality clips. Gemini Omni Flash focuses on iterative, conversational editing that combines multiple assets such as images and video.

Do the outputs have a watermark?
Google applies an invisible SynthID watermark to all videos from Gemini Omni Flash. It does not change how the video looks or sounds, but it stays embedded in the file to mark it as AI-generated.

Can I use Gemini Omni Flash videos for commercial projects?
Gemini Omni Flash is a proprietary Google model. Commercial use is governed by Google's terms of service. Review the current terms for your specific use case, and note that outputs carry the SynthID watermark.
