Working with Audio Contexts
While working on one clip or branch of the process tree, you can listen to the audio of another clip. Audio
contexts work in much the same way as video contexts. You can set up to two audio contexts in ConnectFX.
To set an audio context:
1 In the schematic, select a clip that contains audio.
2 Click the Au Context button, or right-click the clip and select Set as Audio Context.
Clips with an audio context are labelled A1 or A2 and are outlined by a pink dotted line.
3 To hear an audio context, select Context1 or Context2 from the Audio Source box in the ConnectFX
Preferences menu.
NOTE Playback of audio is only available when playing a clip. However, you can scrub audio anytime in ConnectFX.
You can scrub your audio context by using Alt (quick scrub) or Alt+Ctrl (real-time scrub) on any node.
About CFX Output Nodes
A ConnectFX pipeline always terminates with a CFX Output node. This node is created automatically when
entering ConnectFX from the timeline and cannot be deleted.
Both RGB and alpha results can be generated from a CFX Output node to the timeline.
Since an effect created in ConnectFX is a setup applied directly to one or more timeline segments, CFX can
be rendered directly in ConnectFX or upon returning to the timeline. If rendered in ConnectFX, a clip may
be previewed by clicking the Player button.
Naming Output Nodes
The CFX Output node and ConnectFX inherit the timeline segment name by default. To help organize
outputs, an Output node can be automatically named as any output socket in the process tree. To do this,
select the Output node in the schematic, then press N and click any node output: the name of the Output
node is updated accordingly. To change the Output node name or to change the name of the original output
socket, simply redo this naming process.
Renaming the CFX Output node automatically renames the segment at the timeline level as well as the
ConnectFX in the Media panel. Renaming the timeline segment similarly updates the CFX Output node
and the ConnectFX.
NOTE Once the ConnectFX name is explicitly modified, the timeline segment and CFX Output Node names are
no longer automatically updated.
Outputting an Alpha to the Timeline
Alpha results may be outputted in addition to the RGB result from a CFX Output node. Connect the RGB
result to the front input of the CFX Output node, and the alpha result to the matte input of the CFX Output
node. The output node now displays CFXa. Both results are updated on the timeline.
A Comp Timeline FX is automatically added on output, provided that the Add Comp On Matte Output
button in the ConnectFX section of the Preferences menu is enabled (default).
