Description
Product Overview
AJA Corvid 44 12G is a PCIe 3.0 x8 video I/O card built around four bidirectional 12G-SDI HD-BNC connections for high-density capture and playback. It handles 8K, UltraHD2, 4K, UltraHD, 2K, HD, and SD formats, with high-frame-rate workflows reaching 50/60p where the host system supports them. Full-height and low-profile versions are available with active or passive cooling, giving broadcast, post-production, and virtual production systems a compact route to multi-format SDI I/O.
The AJA Corvid 44 12G is a multi-format PCIe video I/O card available from Coremicro (coremicro.com), an authorized AJA dealer based in Union City, California. The card provides four bidirectional 12G-SDI HD-BNC connections, an 8-lane PCIe 3.0 electrical interface, and format support through 8K 8192 × 4320p60. AJA lists a US MSRP of $4,498 for the Corvid 44 12G family. Corvid products include a three-year AJA manufacturer warranty and access to AJA technical support.
8K and UltraHD2 Capture up to 60p
8K high-frame-rate video I/O reaches 8192 × 4320p60, while UltraHD2 reaches 7680 × 4320p60. Film rates including 23.98, 24, 47.95, and 48p are supported across 8K, 4K, and 2K workflows. Host performance matters — AJA notes that not every system configuration can sustain every raster and frame rate.
Real-Time Downstream Keying up to 4K
Hardware downstream keying supports graphics with alpha over video, matte, or framebuffer content up to UltraHD and 4K. That keeps overlay work inside the I/O path for live production graphics, broadcast branding, and real-time compositing without moving the keying task into a separate external device.
SCTE-104 and Dolby Vision Metadata Workflows
SDI metadata workflows in AJA Control Room can capture ancillary metadata such as SCTE-104 and Dolby Vision metadata, preserve it alongside media, and export synchronized sidecar data on a per-frame basis. AJA specifies this metadata toolset for macOS and Windows, making it useful in broadcast compliance, mastering, and post-production pipelines where metadata continuity matters.
12G-SDI I/O for Unreal Engine Virtual Production
Unreal Engine virtual production workflows can ingest live SDI camera feeds, combine them with rendered environments, and return the composited result over SDI. This makes the card relevant to augmented reality, on-set VFX, eSports production, and broadcast studios that need real-time interaction between camera signals and rendered content.
Genlock and LTC Reference for Frame-Accurate I/O
LTC and reference support includes a switchable HD-BNC reference connection on full-height models plus an internal LTC header. Reference accepts analog color black, composite sync, or HD tri-level sync, giving studio, broadcast, and post systems a direct way to align video I/O with facility timing.
Sony 9-Pin RS-422 for Frame-Accurate Deck Control
RS-422 machine control uses Sony 9-pin protocol for frame-accurate ingest and layoff workflows. Both low-profile and full-height cards provide RS-422 through an internal header, while full-height models can expose the connection on the PCIe bracket through a DB9 cable.
Four Bidirectional 12G-SDI HD-BNC Ports
Each SDI connection can be configured for input or output. At 2K and HD, capture and monitoring can run simultaneously, while 4K and 8K routing depends on whether the workflow uses single-link 12G-SDI or grouped SDI connections.
HDR, LUT, and FPGA Processing Support
The platform supports VPID signaling for SDR and HDR characteristics, PQ, HLG, Dolby Vision workflows, HDR metadata capture, up to 12-bit LUT files, and dynamic FPGA firmware reconfiguration for application-specific processing.
Embedded SDI Audio for Multi-Channel Production
Each 12G-SDI connection carries up to 16 channels of embedded audio at 48 kHz. Across four connections, that supports dense broadcast and live production systems where video and multi-channel audio need to remain synchronized through the same PCIe I/O card.
Broadcast Engineers
For multi-format SDI ingest, monitoring, keying, reference, and machine-control systems inside broadcast workstations.
Virtual Production
For Unreal Engine and AR stages that need real-time SDI exchange between cameras, render systems, and program output.
Post-Production
For high-resolution capture, playback, HDR metadata, LUT, and reference-driven mastering workflows.
Live Production
For multi-channel 4K and HD systems that need flexible SDI I/O, embedded audio, and hardware keying.
eSports Production
For graphics-heavy productions combining live sources, rendered environments, and high-frame-rate outputs.
OEM Developers
For custom systems built around AJA's developer ecosystem, PCIe I/O architecture, and configurable FPGA hardware.
AJA Support and Warranty
AJA covers Corvid products with a three-year manufacturer warranty and provides technical support for installation, configuration, and operation.
