The Viz Engine Output Keeps Going Black Randomly

If you are using your Viz Engine as a preview server you may see this behavior. Use another Viz Engine to serve out thumbnails.

When I Run Viz Engine in Fullscreen My Graphic Quality Downgrades to SD

This typically happens when using multiple screens. Verify that Video wall/Multi display is set correctly in your Viz Engine.

Go to Viz Configuration > Video Output > Video wall/Multi display and set this to active.

Video Transfer from a Search Result to a GFX Channel Stays on 0%

This can happen if Media Sequencer did not grab the information for asset storage(s).

To resolve this in Viz Multiplay, go to Settings > General > Active Profile and set it to No Profile, and then back to the one you were using. This reinitiates all transfers.

Video Transfer from a Search Result Gives Errors

No destination available errors can occur when there is an error with the publishing point in Viz One. Verify that your Viz One can FTP into your Viz Engine.

The Search Panel Looks Disabled and It Returns an Error about Viz One

Viz Multiplay can’t access Viz One. This could be because there is no network connection to Viz One, or because there is incorrect host or login information.

In Viz Trio, verify the Viz One configuration by going to Search Media and performing a search. In Viz Multiplay, when you get the Viz One popup, use the same credentials as you used in Viz Trio.

My Clips/Graphics do not Appear on the Output Engines when I Put Them On Air

Always double check that the elements can be played out from Viz Trio. Also, run Media Sequencer in a console (not as a service) to get more information on what is wrong when taking elements on air. The messages in Media Sequencer console are often very useful.

No Thumbnails for My Graphics Appear in Viz Multiplay

Media Sequencer produces the thumbnail URLs for the elements, so it needs to have a Preview Server configured:

1. Go to Settings > Servers in Viz Multiplay, and verify that a preview server host is set.
2. When Viz Multiplay is loading, inspect the network traffic in the browser and look for the requests to Preview Server. Check the HTTP response, which contains an error message.

The Show Opens but Doesn’t Display Any Stories or Content

If a Viz Trio show contains elements which are not within a group, then they will not be visible in Viz Multiplay. The show may appear empty in Viz Multiplay, even though Viz Trio show contains elements.

Create a group in the show and move elements into the group.

I Have Set up Profiles but Get an Error about No Viz/Video Program

The error may look like: No Viz/video program for this entry. Please check the Viz/video program output configuration.

This means that an element has been added to a channel that does not support it (for example, adding video to a graphics channel or vice versa). This can also occur if a profile is selected which does not have a program channel. Also try to deactivate the profile and reactivate it again.

Problems Running Preview Server

To troubleshoot Preview Server, go to the debug page for Media Sequencer on http://mse-host:8580/debug and browse to your show elements. Do you see thumbnails on this page? If not, click on the thumbnail and you will get an error message. You can also inspect the network traffic in the browser (in Chrome and Firefox by pressing F12 and going to Network) when loading the show in Viz Multiplay. Inspect the HTTP response of the broken Preview Server requests, this should give you a hint as to where the problem lies.

Viz Multiplay Limitations

• Thumbnails for graphics with video texture will only display the graphic.
• Running Cleanup also cleans up the Presets scene. Therefore, after a cleanup, you must run a Preset before running other elements. To do this, click on a Preset.
• Avoid initializing while On Air, as this can result in a lag in the graphics output.
• Viz Multiplay does not support videos with overlay graphics as a timeline. To display graphics on top of videos, place GFX channels on top of each other and play elements manually in each channel.
