AESyphon is a plug-in for Adobe After Effects that acts like a Syphon server and provides a live preview to any Syphon client. Just drop the file in the Plug-ins folder, start After Effects and you are ready to go.
PLEASE NOTE: AESyphon does not appear anywhere in After Effects. It is a plugin without a user interface. Simply start After Effects and your Syphon client will show the input from After Effects.
Just unzip the file and move it to your After Effects’s plug-in folder. Typically:
/Applications/Adobe After Effects CC/Plug-ins/
