Use the Streams tools to perform identical processing on multiple image streams avoiding the creation of identical sub-graphs to process a number of images in the same way. The Streams tools can also be used to support a stereo workflow in Composite —see Stereo Viewing. There are three Streams tools:
| Use: | To: |
|---|---|
| Merge Streams | merge multiple single-stream image inputs into a single multi-stream output. It has a single multi-valued image input socket, and a single output socket. You can connect as many inputs as you like to the Merge Streams tool. |
| Extract Streams | extract single-stream image outputs from the Merge Stream node using the Selector value editor. |
| Stereo Streams | input left eye and right eye image streams to create a 2-stream stereo image. The Stereo Streams tool takes two single-stream inputs and combines them into a single dual-stream output, placing the left image in stream 0, and the right image in stream 1. |
In the application, the default stream is stream 0. For example, if a color picker is used in the player, it will pick stream 0. If you pick a color in the Keyer, it will pick the color from stream 0. If you click Fit to Source in a warp tool, it will fit to stream 0.
