Input Tab

Let’s consider configuring an input channel first. An input supplied by a SMTPE 2110 source is automatically converted to an NDI stream. The editable Channel Name under the viewport identifies output the channel to other NDI-enabled systems on the network.

The tabbed Input pane allows you to the video sources for this channel and set its format. The Video Source information display identifies the specific input you have chosen to configure. The nearby Video Format menu allows you to match the input to the format of the incoming SMPTE 2110 video stream.

A Delay setting is provided for both audio and video sources, allowing precise A/V synchronization where a/v source timing differs.

Capture

This tab is also where you assign the path and filename for captured still images.

The initial Grab Directory is the default Pictures folder on the system, but you can choose to use a network storage volumes or external drive connected to one of the USB ports on your Viz 2110 I/O’s rear panel instead.

Audio Levels

Faders in the Audio Levels section of the Configure Channel > Input tab let you modulate the audio levels for up to eight audio channels incoming from SMPTE 2110. The VU meters above the faders are calibrated in dB FS (Full Scale). Click the Speaker icon above an audio channel to mute the associated audio stream.

If you open the Configure Channel pane for an output, instead, there are settings related to output from the channel to SMPTE 2110.

The first choice you will usually make is which audio/video source you wish to output as SMTPE 2110. Often, you use the Audio/Video Source menu to select an NDI A/V stream from your network, but there are other possibilities, too. Selecting a Video Format at right determines the video output format applied.

Clips and IP Sources

As mentioned in the previous section, NDI® sources (such as a PTZ camera with native NDI network video output) can be directly selected. The Video Source drop down menu also contains an Add Media item to let you select a video file to play. The Add IP Camera menu item requires a little more explanation.

Clicking the Add IP Camera entry opens the IP Source Manager. Adding entries to the list of sources shown in this panel causes corresponding listings to appear in the Local group shown in the Video Source menu of the Configure Channel panel (along with the SMTPE 2110 inputs from SFP A and B). To use, click the Add New Camera menu, select a source type from the dropdown list provided. This opens a dialog suited to the particular source device you wish to add, such as one of the numerous supported PTZ camera brands and models.

Supplemental Audio Device

The Supplemental Audio Device allows you to direct audio output to system sound devices as well as well as any supported third part audio devices you may connect (typically by USB). As required, Audio Format options are provided in a menu at right.

Color Tab

Both input and output channels provide a Color tab.

This panel provides an extensive set of tools for adjusting the color characteristics of each video channel. Choosing Auto Color automatically adapts color balance as lighting conditions change over time.

By default, each camera with Auto Color enabled is processed by itself. Enable Multicam to process multiple cameras as a group. To apply Multicam to a source without its own colors being evaluated, check Listen Only. Typically, you enable Listen Only for all Multicam group members except one to make that source the master color reference.
