Gemini Omni 1.1 (Text-to-Video with Native Audio)

What is Gemini Omni 1.1?

Gemini Omni 1.1 (Gemini Omni 1.1 Flash) is Google's natively multimodal video generation model that turns a text prompt, and optionally images, into a short video complete with synchronized audio. Built on the Gemini Omni family and served through the Gemini Developer API, it processes text, image, audio, and video together, grounding motion in real-world physics and knowledge rather than surface-level pattern matching. On Segmind you call it as a simple text-to-video endpoint: send a prompt, get back an MP4 with a matching soundtrack. It is a fast, production-ready choice for developers and creators who need cinematic clips, animated stills, and consistent characters without stitching together separate generation and audio tools.

Key Features

• •Native text-to-video with synchronized audio generated in a single pass.
• •Multimodal inputs: animate a first frame, interpolate between a first and last frame, or seed subjects and styles with 1-10 reference images bound in the prompt using tags like <IMAGE_REF_0>.
• •Resolution control from fast 360p drafts through 720p, 1080p, and 4K (1080p and 4K are upscaled).
• •Aspect ratios for landscape (16:9) and vertical (9:16) delivery.
• •World-knowledge grounding for physically plausible motion, plus SynthID watermarking on every output.

Best Use Cases

Gemini Omni 1.1 shines for social and marketing clips, product shots brought to life, explainers, mood films, and rapid concept prototyping. In our testing, a single text prompt produced a clean, photorealistic 720p ocean-waves scene at golden sunset with dramatic sea spray and a matching audio track of crashing water, no separate sound step required. Use 360p to explore ideas quickly, then regenerate a favorite at 1080p or 4K for delivery. Reach for first and last frame interpolation to build smooth transitions, and reference images to keep a character or style consistent across a scene. Vertical 9:16 output slots directly into Shorts, Reels, and TikTok workflows.

Prompt Tips and Output Quality

Describe the scene, subject, camera movement, lighting, and mood, then spell out the sound you want, since explicit audio cues drive the synchronized soundtrack. For one continuous take, add phrasing like "single unbroken shot, no scene cuts." You can time events with natural language or a timecode syntax such as [0-3s] ... [3-6s], and place negatives directly in the prompt (for example, "no dialogue"). Duration is guidance honoured through the prompt and capped at 10 seconds per output; English prompts are fully supported. Detailed, specific prompts consistently beat vague ones.

FAQs

Does Gemini Omni 1.1 generate audio? Yes. It creates a synchronized audio track alongside the video in the same request; describe the sound in your prompt for best results.

Can I animate an image? Yes. Provide a first frame to animate a still, add a last frame to interpolate a transition, or pass reference images to carry subjects and styles into a new scene.

What resolutions and aspect ratios are supported? 360p, 720p (default), 1080p, and 4K, in 16:9 or 9:16. 1080p and 4K are upscaled outputs.

How long can the video be? Each generation is 3 to 10 seconds; requests longer than 10 seconds are clamped to 10 seconds of output.

Is the output watermarked? Yes. Every clip includes an imperceptible SynthID watermark for AI provenance.

Which languages work best? English is fully supported; other languages may work but are not formally evaluated.
