NDI Tally

Multiview for NDI supports displaying NDI tally status (preview/program) on each viewport. Tally can be reported via a border color change, a tally PNG flag, or both.

Each viewport can have it's own settings (breakaway), or you can apply the same settings to every viewport.

NDI Tally state is available in 2025.6.18.1 and onward.

Tally Flag Defaults

Before setting up your tally flag defaults, you should set up your viewports. These defaults will only apply to the viewports that exist when Apply to All Viewports is clicked.

In Edit Layout, there is a section called Tally Flag Defaults. This allows you to set the default tally flag PNG for all viewers.

By default, Multiview for NDI ships with the following tally flag PNGs.

Name	Image
pvw.png
pgm.png
pvw_triangle.png
pgm_triangle.png

In our example, we will set the Preview Flag to be pvw.png and the Program Flag to be pgm.png.

Next, we will set the location of those flags, along with border changes.

Flag Location & Border Changes

Tally flags can be positioned at the top-left, top-center, top-right, bottom-left, bottom-center, and bottom-right of a viewport.

If None is selected, that tally flag will never be displayed.

An NDI source can be in preview and program simultaneously. In that case, both flags will display if configured to display.

For the Border option, you can choose to have Multiview for NDI highlight the viewport with a Green border for preview, and Red for Program.

If a source is in both preview and program, the program border highlight will take precedence.

For this example, we will set the Preview Flag to display at the Bottom-Center, and the Program Flag to display at the Top-Center, and apply a border highlight when the viewport's source is in preview/program.

Click on Apply to All Viewports to apply the changes to this layout.

You will need to click Save Changes below to see these tally flag changes appear.

Applying Tally Flags & Borders Per Viewport (Breakaway)

After selecting a viewport in Edit Layout mode, you can set the location of each tally flag, along with border highlight.

Once finished, click De-Select, then Save Changes to see your tally state changes.

With some NDI sources added to your multiview, you should see tally similar to the following.
