Parameters
Every generation setting Vizzy manages — aspect ratio, resolution, model, and video duration, audio, and loop — and how to set each one by chat or in the advanced controls.
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. Paid plans produce images up to 4K quality, print-ready. Higher resolution looks sharper but costs more credits 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 Nano Banana Pro".
Video parameters
These apply in Motion mode.
| 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 Veo" |
Motion renders at up to 1080p on Pro and up to 4K on Max. Image upscaling goes up to 16 MP on Pro and 32 MP on Max. See Plans & credits.
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 Motion · 5s") and the form controls update to match. Nothing changes silently.
