Veo 3.1 model details
A deeper guide to Veo 3.1 input modes, quality choices, reference control, vertical video, and production settings in GemiOmni.
Veo 3.1 is for more controlled video work: text prompts, image-to-video, reference-to-video, vertical or horizontal framing, and quality modes. Use it when the clip needs a tighter relationship between prompt, reference images, camera movement, and final placement.
What do Text, Image, and Reference modes mean?
Text mode creates a scene from the prompt alone. Image mode uses first and last frame guidance for stronger visual control. Reference mode can use multiple images to guide subject, style, or composition when consistency matters more than pure exploration.
- Text-to-video for new scenes
- Image-to-video for frame control
- Reference-to-video for consistency
- Up to 3 reference images
How should I choose Lite, Fast, or Quality?
Use Lite or Fast when you want faster testing and prompt iteration. Use Quality when the shot needs better motion, light, detail, or production value. Reference-to-video currently uses Fast mode, so switch modes deliberately when you move between reference control and final-quality testing.
- Lite/Fast for iteration
- Quality for final candidates
- Reference mode uses Fast
- Test prompts before final runs
Which output settings does Veo 3.1 support?
Veo 3.1 in GemiOmni supports 16:9 and 9:16 output, Auto aspect where the selected image mode allows it, plus seed and watermark controls. It is especially useful when a single scene needs controlled framing for social video, ads, and cinematic placements.
- 16:9 and 9:16
- Auto for supported image modes
- Seed support
- Watermark control
Veo 3.1 vs Kling or Wan: when should I switch?
Choose Veo 3.1 for controlled cinematic scenes and reference-driven output. Try Kling for dynamic physical motion, Wan for stylized or flexible video prompts, Seedance for people and movement, and Hailuo for quick visual exploration.
- Veo 3.1 for control
- Kling for motion
- Wan for style
- Seedance for people and action
What prompt structure works best for Veo 3.1?
Use a compact production brief: subject, action, camera movement, lighting, location, mood, and intended platform. If you upload references, explain whether each image controls identity, style, background, or first/last frame.
- Subject plus action
- Camera and lighting
- Reference roles
- Platform-specific framing
