Port Numbers

The table below lists all default server and listening port numbers used. When the firewall is well configured, it can be kept enabled. Client-side firewalls may cause issues when the Viz Artist/Viz Engine version is below 3.8.2 or the Graphic Hub version is below 3.0.0, since the communication protocol used was two-way and requires the firewall on the client side to be open for the Viz Artist/Viz Engine processes. However, it is not required to disable the firewall completely.

Port(s)

Descriptions and comments

MVCP and Xlator control port for video servers.

VDCP ports

Control Ports

6100 TCP
6700 TCP
6800 TCP
55000-55031 TCP
56000-56015 TCP

Communication ports used by Control Applications (like Media Sequencer) to connect to a Viz Engine program and/or preview channel. Viz Engine’s default program and preview port is 6100.

In a single channel configuration where both program and preview output is on the same machine, the default preview port is set to 6800 to separate the program and preview channels.

In a dual channel configuration, the default program ports are 6100 and 6800 for channel one and channel two, respectively. In a dual channel configuration, when used for stereo production, the default program ports are 6700 and 6800 for channel one (left eye) and channel two (right eye), respectively.

For controlling Graphics Channels and/or Super Channels, ports 55000-55031 and 56000-56007 are used (can be changed in the config).

These ports are configurable via Config GUI.

Multiplexing Ports

Ports

Viz Engine

All other ports

Still Preview Port

MUX Isolated PortMUX Shared PortMUX Fixed Port

The multiplexer functionality is an integral part of Viz Engine. When using Viz Engine a session management takes place internally, with one default session for the GUI and internal/external commands, and additional sessions created on-demand for the multiplexing ports or the preview port.

With multiplex ports, other than the MUX Still Preview port, the Viz Engine state is only switched when a command is received, which means a new session is created; hence, ten consecutive commands from a client only results in one state switch on the first command.

  • The MUX Still Preview Port (50010) state is switched when a command is received and immediately switched back to the main session such that On Air rendering is not hindered in any way.

  • The MUX Fixed Port (50009) is traditionally used by the old Viz Pilot Newsroom Client, and is the same as the MUX Shared Port, except that allocated resources are never cleared from memory. To avoid memory overload, it is recommended to clean up the Viz Engine regularly when this port is used.

Info: There is no automated cleanup of memory on this port.

  • The MUX Shared Port (50008) is a shared port where all connections from one single host shares one session. It is most often used by Viz Trio and the Newsroom Client to show preview frames.

  • The MUX Isolated Port (50007) is an isolated port where all connections get their own session. It is used, for example in an NLE configuration, to deliver frames to the host NLE-system when rendering or scrubbing video clips with graphics. Using this port also suppresses bounding box commands.

All multiplexing ports are supported by all Viz Engine versions, but require a license.
