AJA Corvid 44 12G PCIe 4-Channel 12G-SDI Full-Size BNC I/O Card (Tall Bracket, Fan)

AJA Corvid 44 12G Overview

AJA's Corvid 44 12G PCIe 4-Channel 12G-SDI Full-Size BNC I/O Card is an 8-lane PCIe 3.0 card with four bidirectional 12G-SDI BNC connectors. The bidirectional aspect provides a lot of flexibility for simultaneous capture and pass-through. The advanced card also offers a BNC reference input and internal 9-pin RS-422 port. This version of the card features a tall outer metal bracket for standard size systems and has a built-in fan on the rear for active cooling.

The card is designed for demanding video and audio workflows in applications including HFR, 8K, 4K, 2K, HD, SD, Deep Color, and HDR. It supports 10-bit 4:2:2 and 4:4:4 at up to 12-bit color spaces, and it allows for both ingest and output over backward-compatible 12G-SDI.

Key Features

• 12G-SDI I/O for 8K, UHD-2, DCI, UHD, 2K, HD, and SD with HFR support up to 8K60p at YUV 10-bit 4:2:2, and support for RGB 12-bit 4:4:4 up to 8K30p
• Four bidirectional 12G-SDI BNC connectors and one Reference In BNC
• LTC input via Reference In (switchable) on the card header
• 16-channel embedded SDI audio per 12G-SDI port
• 10-bit downstream keyer in hardware, supporting up to 4K resolution
• AJA SDK compatibility on Windows, macOS, and Linux, offering advanced features including multichannel 4K I/O
• Low-profile design for use in workstations or servers
• 8-lane PCIe 3.0 design
• RS-422 serial control via an internal 9-pin port on the header of the card
• Active heatsink
