AVMatrix VC12-4K Single-Channel HDMI 2.0 4K60 PCIe Capture Card

AVMatrix VC12-4K: A Dedicated 4K60 Capture Engine Inside Your PC

The AVMatrix VC12-4K is a single-channel HDMI 2.0 PCIe capture card that pulls a 4K60 source directly into a computer's expansion bus. It is built for the operator who wants capture that lives inside the machine, free from the bandwidth ceilings and cable-shuffle of external dongles. With an HDMI loop-out, high-bit-rate capture, and hardware image processing, it turns a desktop into a purpose-built recording and streaming workstation. For serious rigs that run for hours, it is the difference between a convenience accessory and true production infrastructure.

Why a PCIe Capture Card Beats USB

A PCIe capture card connects to the CPU over the motherboard's expansion bus rather than a shared USB port, so it gets dedicated, high-bandwidth throughput with lower and more consistent latency. The VC12-4K uses a PCIe 2.0 x4 interface offering 2.5 GB/s of bandwidth, well beyond what USB devices can sustain, which is what allows reliable 4K60 capture at bit rates up to 800 Mbps. Internal mounting also removes the failure points of external cables and bus-power limits. For 24/7 and mission-critical work, that stability is the whole point.

Image Processing on the Card

The VC12-4K performs hardware de-interlacing on 1080i sources and applies 3D noise reduction, cleaning the picture before it ever reaches your software. Doing this work on the card offloads the host CPU and delivers a smoother, cleaner feed for encoding and recording. The single HDMI 2.0 input includes a loop-out so you can drive a local monitor at full resolution while capturing. These are the touches that separate a professional card from a bare frame-grabber.

Multi-Card and Continuous Operation

Multiple VC12-4K cards can share a single system, letting builders assemble multi-input capture servers from a stack of identical cards. The card is rated for continuous 24/7 operation, suiting monitoring, logging, and always-on broadcast applications. It is supported on Windows 7 and newer and Linux 18.04 and newer, and works with OBS, PotPlayer, and XSplit. For a capture PC that never gets turned off, it is engineered to keep running.

Built for Capture Workstations and Broadcast PCs

The VC12-4K targets high-bitrate 4K capture stations, live streaming and recording rigs, multi-card capture servers, and broadcast production computers. Anyone assembling a dedicated capture workstation gains a card that treats 4K60 as a baseline rather than a stretch. Its internal design keeps the desk clear and the signal path short, and its processing features lighten the CPU's load. For the builder who wants capture engineered into the machine, the VC12-4K is the anchor component.
