Action nodes provide in-context access to a fully functional Action module. The Action node supports direct media and indirect media.

Indirect media is connected directly to an Action Media node and appears in the schematic. With indirect media, you can connect any source (a clip, node, or group output, for example) to an Action node. Indirect media is available only with Action nodes in Batch.

Direct media appears directly inside an Action node. Although direct media does not appear in the schematic, media and all related settings are saved with the Batch setup. Direct media is also supported by the Action module.

The Action node supports multiple outputs. For example, you can set up your scene to output your entire composition or just the mattes and then select the type of output you want to process. You can also output stereo results of your scene.

If you are working with stereo material, you can automatically set the startup mode to stereo when you drag an Action node from the node bin. This prevents you from having to manually set stereo settings.

The chapters in the 3D Compositing with Action section provide detailed information on how to work with Action.
