One of common cases of using vizrt is videowall. Often the outputs have non standart proportion. Videowall in TV studio is a custom product constructed from several panels or blocks. So if you need to create a graphic for videowall you have to organize workflow of creating graphic templates.

Main parameter of proportion in vizrt is “Aspect”. For example 16:9 = 1.777(7)

For example: composite videowall with 6 standart 16:9 panels, three columns and two rows.

16:9 16:9 16:9
16:9 16:9 16:9

Total aspect is (16*3):(9*2) = 48:18 = 2.666(6)

Seting up custom aspect

For convenient workflow you have to change the setting:

If you are creating not only one format you can copy config and shortcut for launching Artist with different config.

Creating scene in new config Artist:

Using custom scene with standart license Engine

In onair we use standart VizEngine and VizTrio for videowall:

This Engines are configured with standart aspect 1.777(7) because 16:9. Our scene doesn’t work properly if scenes have setting “Camera Aspect = Config.” We must change aspect in scene to “User” with certain number.

This scene setting overrides config.
