Parameters
Every generation setting Vizzy manages, from aspect ratio, resolution and quality to video duration, audio and loop and the 3D level, and how to set each one by chat.
Vizzy sets sensible parameters for you on every generation, so most of the time you can ignore this page. When you do want control, you have two ways to change any setting: just say it in chat, or open the advanced controls in the message bar. Manual changes always win over Vizzy's defaults.
You rarely need the controls panel. "Make it 16:9", "portrait", "higher resolution", "5 seconds", "add sound" - Vizzy applies the change and confirms it inline. See Talking to Vizzy.
Image parameters
Aspect ratio
The shape of the output. Common options include square (1:1), landscape (16:9, 4:3, 3:2), and portrait (9:16, 3:4). There's also an auto setting: when you're rendering from an uploaded image, auto matches the output to the base image's proportions so nothing gets cropped or stretched.
Say: "change to 16:9", "make it portrait", "match the original".
Resolution
How much detail the render is generated at. Free renders up to 1K, Hobby up to 2K, and Pro and Max up to 4K, print-ready. Higher resolution looks sharper but uses more of your plan and takes a little longer.
Say: "higher resolution", "4k please".
Model
Which generation model produces the image. Vizzy picks a default suited to your request; you can switch - for example to a premium model for a tougher scene. See the Models reference.
Say: "use the pro model", "use Ultra quality".
Background
Whether the image comes back as a PNG with a transparent background. Vizzy turns it on when you ask for a cutout, a sticker or "no background". It works on Pro and Ultra; on Base Vizzy asks you to switch first. See Transparent backgrounds.
Say: "on a transparent background", "cut it out, no background".

Video parameters
These apply when you generate video.
| Parameter | What it does | Say something like |
|---|---|---|
| Duration | Length of the clip in seconds | "make it 5 seconds" |
| Aspect ratio | Landscape for walkthroughs, portrait for social | "vertical video" |
| Audio | Turn generated sound on or off | "add sound", "no audio" |
| Loop | Make the clip seamless for backgrounds | "loop it" |
| Model | Which video model renders the motion | "use another video model" |
Video renders at up to 768p on Hobby, 1080p on Pro and 4K on Max. Image upscaling goes up to 8 MP on Hobby, 16 MP on Pro and 32 MP on Max. See Plans and renders.
3D model parameters
These apply when you make a 3D model. A 3D model has one setting, the level, in the same quality menu as images: Pro (the default, the most detail, 900 credits) or Standard (smaller files, 300 credits). There is no aspect ratio, resolution or duration. The views themselves are the input: one to four images of the same object, and Vizzy works out which side each one shows.
Say: "use Standard for this one", "make it at Pro detail".
How Vizzy confirms changes
Whenever a parameter changes - whether you typed it or Vizzy adjusted it - a compact inline note appears in the chat (for example, "Aspect ratio → 16:9" or "Switched to Video · 5s") and the form controls update to match. Nothing changes silently.
