12G-SDI, Multi-Format PCIe I/O Card

Corvid 44 12G BNC boasts four bidirectional 12G-SDI spigots with a Reference Input. 8K Input or Output is possible using quad 12G-SDI cables and 4K/UltraHD I/O can be achieved with either a single 12G-SDI or 6G-SDI cable, or quad 3G-SDI cables. 2K/HD I/O can be achieved with a single SDI cable or dual link SDI, while allowing capture and monitoring via SDI to take place simultaneously.

Corvid 44 12G BNC is available with either active (fan) vs. passive cooling (no fan), with both versions supporting RS422 and LTC Input via headers on top edge of the card.

Other Corvid 44 12G models are available, including low profile versions with HD-BNC connections.

Raster and Frame Rate Support

Corvid 44 12G BNC supports 8K (8192 x 4320) and UltraHD2 (7680 x 4320) High Frame Rate (HFR) workflows up to 50/60p for the most demanding applications. Film rates of 23.98, 24, 47.95 and 48p are also supported across 8K, 4K, and 2K.

High frame rates are also available on multiple I/O 4K, UltraHD, 1080p and 720p HD up to 50/60p, making Corvid 44 12G BNC extremely flexible for your current and future needs.

Hardware Keying

The built-in hardware downstream keyer allows graphics and images to be easily overlaid on the input video in real time up to 4K.

Reference and LTC Input

Corvid 44 12G BNC provides one external, switchable LTC/Reference Input connection on the back of the card.

RS-422

A built-in RS-422 connection is available as an "internal" connection via a header on Corvid 44 12G BNC. RS-422 allows control of external devices for frame accurate ingest and layoffs.

Industry Leading Support

AJA’s technical support is recognized as among the best in the industry and is available to all AJA customers. If you need assistance with any aspect of your Corvid installation, configuration, operation or encounter any technical issue, AJA Support will work with you to get up and running.

Corvid products are covered by a generous three year warranty, including advance replacement as standard.
