BlueFish444 IridiumSD

BlueFish444 Iridium|SD is the native successor of the Digital Voodoo DeepBlue LT and the predecessor of BlueFish444 SD Lite Pro Express, providing Fill, Key, GenLock and Composite Fill connectors. The Iridium|SD is fully compatible with older DeepBlue-LT installations.

The card was mostly used with Viz Trio NV which basically was a system with the ability to run a Viz Trio client with local preview and video output on a single machine; hence, there was no video input or video playback support as with the Matrox X.mio Series. The local preview was able to render a different scene than the one being output on video. The card was typically seen on HP xw4600.

IMPORTANT! Supports for the Iridium|SD card ended with Viz Engine 3.5. For supported versions, see the most recent BlueFish444 cards.


The BNC connectors from left to right are:

  • SDI Out A (Fill) - SDI 4:2:2/4:4:4/Video

  • SDI Out B (Key) - SDI 4:2:2/4:4:4/Video

  • Ref In - Analog GenLock input

  • Composite Out - Composite fill output

Driver Installation

The driver installation works the same way as for DeepBlue-LT cards. Use driver versions available on the Vizrt FTP server to make sure of correct functionality and ring buffer support.

Iridium|SD is fully compatible with existing DeepBlue-LT installations and can be used with any recent Viz version supporting the older DeepBlue-LT device.

Caution: Only Bluefish444 v3.1 is guaranteed to support an adequate ringbuffer size. Any other driver reduces or completely disables ringbuffer support.
