AJA Compact 12G-SDI Power
Desktop I/O
Overview
Take command of the most challenging projects using the immense power of Corvid 44 12G, AJA’s blazingly fast, compact 8-lane PCIe 3.0 I/O card with four bidirectional 12G-SDI HD-BNC connections, designed for today’s most demanding video and audio workflows. Corvid 44 12G is available in several configurations, including full-height or low-profile, with passive or active cooling.
Whether you are working with HFR 8K/4K/UltraHD, 2K/HD, SD, Deep Color and/or HDR, experience the quality and peace of mind that Corvid 44 12G brings to your projects. Supporting 10-bit 4:2:2 and 4:4:4, at up to 12-bit color spaces, Corvid 44 12G offers ingest and output over 12G-SDI, which is also backwards compatible with 6G-SDI, 3G-SDI, and 1.5G-SDI. The bidirectional 12G-SDI ports provide immense flexibility for capture and simultaneous pass-through for a range of solutions.

12G-SDI, Multi-Format PCIe I/O Card
Corvid 44 12G 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.
The Corvid 44 12G family also includes models for active vs. passive cooling, RS422 on PCIe bracket vs. card header, and HD-BNC vs. full-size BNC connectors.
Flexible Frame Rate Support
Corvid 44 12G 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 not limited to 8K and UltraHD2 with Corvid 44 12G, multiple 4K, UltraHD, 1080p and 720p HD inputs and outputs are also supported at frame rates up to 50/60p, making Corvid 12G 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.
LTC and Reference Input
Corvid 44 12G provides one external, switchable LTC/Reference Input connection on the back of the card. A second LTC input is available on an internal header for providing additional reference to Corvid 44 12G.
RS-422
A built-in RS-422 connection is available either as an external connection on the full-sized Corvid 44 12G or as an internal connection on the low profile Corvid 44 12G. RS-422 allows control of external devices for frame accurate ingest and layoffs.
