Installation

  1. Make sure you have the correct hardware and software platform.

  2. Ensure that Viz Engine is installed and that you have a working local Graphic Hub and Media Sequencer or have network credentials to the Graphic Hub and Media Sequencer.

  3. Download the latest Viz Trio installer and Release Notes with FTP from download.vizrt.com/products/VizTrio/LatestVersion/.

  4. Read the Release Notes carefully. They may contain important last minute information.

  5. Double-click the downloaded installer and follow the installation instructions.

  6. Visit docs.vizrt.com to learn more about the software or press F1 / Help > View Help to browse the local help.

Note:

  • You can only have one Viz Trio installed on a computer.

  • Any installed previous version of Viz Trio installed is overwritten by the new Viz Trio installer.

  • The Installer attempts to preserve previous data/configuration settings.

Upgrade

Follow the upgrade path instructions below to ensure that Viz Trio client, settings, profiles and shows are retained at upgrade.

Updating Viz Trio 4.x

  • Always back up the Media Sequencer file default.xml file before upgrading.

Upgrading to Viz Trio 4.x from 3.x

  • Always back up the Media Sequencer file default.xml file before upgrading.

Major system architectural improvements were introduced with Viz Trio 4.x.

  • All versions of Viz Trio that were released prior to version 4.0 are built with 32 bits. From 4.0 the product is built only for 64-bit Windows and is a 64bit application.

  • Viz Trio 4.0+ can only operate with 64-bit software, incompatible 32-bit software can no longer function with Viz Trio.

Borland Database Engine Limitations

The Borland Database Engine, used in various VTW templates is 32-bit software that is no longer supported.
To use existing VTW templates with Trio 4.x, these VTW templates must first be modified to instead use ODBC database drivers, with no dependency on the Borland Database Engine.

Follow the procedure below.

  1. Freely download the 64-bit version of Microsoft Access Database Engine 2016 Redistributable from Microsoft.

  2. Install on the local computer.

  3. You will now set up an ODBC connection to the Microsoft Access database, to register your database in the system

    1. Run the 64-bit version (not 32 bit!) of the ODBC Data Sources application.

      64bODBC.png

    2. Once ODBC Data Sources (64-bit) is running

    3. Select tab User DSN

    4. Click Add

    5. In Create New Data Source select the driver that matches your database type of your database. For example Microsoft Access Driver:

      setupoODBC.png

    6. Click Finish.

    7. In the ODBC <dBase type> Setup menu that appears provide an alias name (use a name without space characters) for your database that you will be later using in VTW template:

      setupODBC.png

    8. Click Select, then select the database file in filesystem:

      selectDB.png

    9. Click OK.
      Your database is now registered in the system.

    10. In the ODBC Microsoft Access Setup dialog box, click OK.

Modifying VTW Templates

Info:

  • There is a lot of information about how to build connection string over the internet. This is generic in regard to ODBC database access technology

  • You may actually use a connection string that points to the exact location of database file, so you do not need to register your database in the system.
    However, this is a trial and error method, it is highly recommended to register a database alias as the default method.

To modify VTW templates

  1. Start the Template Wizard application and open your VTW template.

  2. Navigate to Database page and on the Component palette put two new components on a form:

  3. ADO Connection

  4. ADO Query
    For example, their names are ADOConnection1 and ADOQuery1

  5. Assign Connection property of ADOQuery1 to ADOConnection1
    This makes the query component use the connection component.

  6. For the property of ADOConnection1, clear the check value of LoginPrompt
    (otherwise username and password will be requested for the Trio session, even if they are not used).

  7. Set the ConnectionString property of ADOConnection1 component to refer to the database you want to use.
    For example, assuming sample screenshots above:
    Provider=MSDASQL.1;Persist Security Info=False;Data Source=MyDatabase;

    conString.png

  8. For those properties that are the same between this new ADOQuery1 component and your existing Query component (let’s say it has name Query1),
    for the ADOQuery1 component set same values as in Query1 component. This could be, for example, the SQL property.

  9. (Example) If the existing Query1 component has some event handlers code, create the same event handlers for ADOQuery1 and copy the code there.

  10. Delete your existing Query1 component so only the ADOQuery1 component remains.

  11. Using Find and Replace, modify the script so it uses ADOQuery1 where Query1 was previously named.

  12. Once you have deleted the Query1 component, delete its event handlers code.

  13. (Optional) You can control your ADOConnection1 connection separately from queries.

    1. You can open the connection once (ADOConnection1.Connected = True) and close it whenever you want.

    2. When the connection is open, setting the ADOQuery Active property to True or False does not affect the connection state.

    3. When the connection is closed, when set to Active, the first ADOQuery will also open the connection.

    4. Closing the connection makes all possible ADOQuery instances inactive (closed) if they were active.

  14. Save the template with a new name (to differentiate it from the old one).

  15. Start Trio 4.x+

  16. Open your show.

  17. Open Show properties.

  18. Click the … icon next to the Active VTW template setting.

  19. In the VTW Templates dialog box, select the existing VTW template and delete it.

  20. Add and select new template that you’ve created at step 13.

  21. Click OK.

  22. Click OK.

The old template is replaced by the new one and is ready to use.

VTW template verification on Trio 3.x

To test upgraded VTW template using Trio 3.x

Technically you don’t need to upgrade from Trio 3.x to upgrade your VTW templates from using Borland Database Engine to ODBC.
This route requires a planned switching to Trio 4.x+ which must avoid using BDE, while still using Trio 3.x.

  • For this route, you follow the same upgrade steps as above, but register your database with the 32-bit version of ODBC Data Sources application instead of 64-bit one.

Important usage Notes

  • Be aware that registering database in 64-bit version of ODBC Data Sources application is crucial in regard of using the VTW template in Trio 4.x+.

  • The 64-bit version of the ODBC Data Sources application allows creating, configuring and removal of only 64-bit connections.
    The 32-bit version of the ODBC Data Sources application allows creating, configuring and removal of only 32-bit connections.
