Generative nodes expose shape settings that get passed to the underlying model.

​
Aspect ratios

Supported aspect ratios across image and video models: 21:9 · 20:9 · 19.5:9 · 2:1 · 16:9 · 3:2 · 4:3 · 5:4 · 1:1 · 4:5 · 3:4 · 2:3 · 9:16 · 1:2 · 9:19.5 · 9:20 · 9:21 Not every model supports every ratio. The node UI hides ratios the selected model can’t produce. Switching a node to another model keeps its aspect ratio when the new model supports it. Otherwise the node moves to the closest ratio the new model offers, so a 4:5 node moved to a model without 4:5 becomes 3:4, not 16:9.

​
Set an aspect ratio on multiple nodes

Select two or more image nodes, or two or more video nodes, and choose Aspect ratio in the Generation settings panel. The change applies to every selected node while preserving each node’s model choice, including Auto. The dropdown offers ratios supported by all selected nodes, using their models and connected inputs. It stays disabled when the selection has no shared ratio. The setting applies to the next generation; existing outputs keep their original dimensions.

​
Image resolutions

​
Video resolutions

​
Durations

Video nodes accept a clip duration in seconds, bounded by what the chosen model supports. Each video model has its own min/max — the node UI clamps your selection to that range.

​
Set the defaults for new nodes

Each model carries its own starting resolution, so a new node inherits whatever the selected model prefers — for most image models that’s 2K. Override it once and every node you create afterwards starts there instead:
  1. Open the hamburger menu in the canvas menu bar
  2. Click Project settings
  3. Expand Image defaults or Video defaults
  4. Pick a Resolution
The same panel sets the default Model, Aspect ratio, Variations, and — for video — Duration. Individual nodes still override their own settings from the node toolbar, so a project defaulting to 1K for drafting can hold a 4K node for the final render. Reset to default in the settings header clears the overrides and hands each setting back to the model. Defaults are shared with your team and apply to every canvas in the project. A canvas that isn’t in a project keeps its own defaults.
