To create a composition with a predetermined set of published ports defined by a protocol, go to the
menu, select , and select the protocol you want. Typically, a protocol is used when running a Vuo composition inside another application, such as a VJ or video postproduction app. That application should instruct you about the protocol to select.The published ports in a protocol appear in a tinted area of the published port sidebars, with the protocol name at the top. You can’t rename or delete these published ports. However, you can add other published ports to the composition and rename or delete them as usual.
