and a single output socket. You can connect as many inputs as
you like to the Merge Streams tool.
extract single-stream image outputs from the Merge Stream node
using the Selector value editor.
Extract Streams
input left eye and right eye image streams to create a 2-stream
stereo image. The Stereo Streams tool takes two single-stream
Stereo Streams
inputs and combines them into a single dual-stream output, pla-
cing 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.
NOTE Paint strokes will only be applied to stream 0.
Performing Multi-stream Processing
You can perform identical processing on multiple image streams. The following
example workflow applies a blur to five imported layers.
To apply a blur to multiple layers:
1 Import multiple layers into Composite. Composite creates a composition
per layer.
2 Perform a multiple selection of the imported layers, drop them into a
new composition and swipe through the Link option. Composite creates
a link node per layer in the new composition.
