vz (ViZualizator) Real-Time TV dynamic graphics production, channel brending, system



vz (ViZualizator) is software complex for generation realtime TV-graphics. Fine and easy solution for TV studio graphics, channel branding and TV-Interective solutions in SD and HD modes.

Scene (or project file) is external file (in XML format). It's tree - based description of graphics primitives layout and operation about parameters changing.

Managing of vz behavior performed by external program that communicate with main rendering module using TCP or UDP protocols. Main program provides telnet-like shell where external commands send throw using predefined syntax. Command could be used for loading "scene" file (primitives layout), modification parameters of graphic primitives or for starting/stopping timeline's complex (called director).

Hardware requirements

Minimum is nVidia VGA board higher ther GeForce 5200, other manufacturer's board not supported. CPU and RAM configuation depends on task it will be used for.

For dual video input channels + animated background its require Dual Xeon configuration with nVidia QuadroFX board.

The easy task you need the lighter hardware configuration required.

Supported Outputs

Video output provided by professional TV video output board. For now there are 2 supported:

decklink (blackmagic design)

  • Decklink Pro: SD modes, tested agains DeckLink Windows 6.8.3 drivers version
  • Decklink HD Pro: SD and HD modes, tested agains DeckLink Windows 6.8.7 drivers version

Board supports only FILL+KEY output operations only. No input available.

Manufacturer site is Blackmagic_Design.


  • SD|Greed, SD modes, tested against 5.4.26 drivers version, input (single and dual) and output (FILL+KEY) supported.

Most tested video output driver. Support almost all hardware supported features.

Manufacturer site is www.Bluefish444.com.


StreamAlphaPlus card tested long time ago. Not sure about current version. Manufacturer site is www.stream-labs.com


Fake output video module. Used for emulating CPU load, texture transfer and can be used as skeleton for writing new output modules

Output driver could be written for almost all adapters with open SDK.

vz linked against libraries supplied by another projects. For compiling VZ you will need:

For operating with vz throw IP i recommend to use PuTTY - A Free Telnet/SSH Client
