In the Matrox section, assign Matrox Input and Output channels to Viz Engine Input and Output channels. The GUI shows a drop down menu for the configurable parameters. The parameters available are dependent on the installed hardware.

This page provides information about the following:

General Properties

The General Properties Panel shows information about the installed hardware.

  • Serial No.: Shows the serial number of the installed Matrox board.

  • Board Info: Shows the model and type of the Matrox board.

  • DSX Info: Shows the software version and driver version.

  • Enable Hardware DVE (former Fast Texture Mode): Disable to shorten the ’in out’ delay in Texture Mode to a minimum.

Note: If Enable Hardware DVE is set to Inactive, DVE does not work (see Video Clip Playout Considerations and Video Playout in the Viz Artist User Guide).

  • Shared Input Host: Used to share the input with other Viz Engine instances.

  • CC Extraction: Enables or disables the closed captioning extraction for Matrox X.mio3 - DSX LE 4.

  • Print Clip Info: Enables printing of clip information to the console when activated. However, such information may cause the render loop to stall. Default mode is Inactive.

  • Watchdog: Sets a timer that allows a system to continue video pass-through during an application crash or system failure (see also Watchdog (Matrox X.mio3 Series) and Video Board):

    • Use Watchdog: When set to Active enables the Matrox X.mio watchdog feature. It passes the input signal to a hardcoded output port as soon as Viz Engine is unresponsive. Default mode is Inactive. 

    • Timeout: Sets the time, in milliseconds, until the watchdog takes over control. This value should not be smaller than the time of two fields/frames. Default value is 999 ms.

Note: Use Watchdog and Timeout can also be set and changed in Video Board.

  • Genlock

    • Use Flywheel: Adopts a tracking mode if the genlock signal is interrupted or lost that maintains the signal frequency until the source genlock signal is regained when activated. Default mode is Active.

    • Max Recovery Time: Represents the time in milliseconds (ms) provided to the flywheel to attempt to regain the genlock before an abrupt jump to the locked state is performed. Default value is 15.

    • Max Unclock Time: Represents the time in milliseconds (ms) provided to the flywheel to remain in the unlocked state before switching to the free running state. Default value is 15.

Configuration File Only

It is possible to increase the delay of the output to 1 frame to mitigate performance related frame drops that are indicated by Buffer has been dropped, cancelled late log messages. Increasing the delay to 2 or more frames does not have additional performance benefits.

This setting is only relevant with boards that do not have a hardware mixer (DSX LE series), or if using that mixer was disabled in the configuration. The most common way to disable the mixer is to Enable Hardware DVE mode.

Set Matrox0.VideoOut1.NodeFrameDelay = 0 to values other than 0.

Note: This value is set to at least 1 internally for UHD outputs on X.mio3 and DSX LE4 cards.

M264 Encoder/Decoder Boards

M264 encoder/decoder boards are usually configured automatically. If they do not appear in the configuration section, please double check the Matrox.Devices entry in the MATROX_CONFIG of the viz.cfg file.

It should look like Matrox.Devices = <device1>,<device2>.

Depending on your model(for example, a M264 S3, which supports three streams), the entry would look like: Matrox.Devices = <device1>,<m264device>,<m264device>,<m264device>.
