Preview and rendering — Natron 2.5.0 documentation

# Preview and rendering

## Preview

While working in Natron you can preview your work in many ways:

- connect the input of the viewer node to the node you want to look

  > - pick the input arrow of the viewer node

  > - select the node to view then use shortcuts `0` to `9`

- select the quality of the render (full/proxy)

- start playing

- the images are rendered in memory

- when the preview render is finished all memories are storeed in the memory cache and the playback becomes realtime and plays in loop

See The Viewer section for more information.

## rendering

When you want to get the result of your nodetree as image file(s) on disk: - create a write node (shortcut `w`) - connect the write node to the last node of your NodeTree

- start the render with the render button in the Write node properties

See The Write node section for more information.
