The Blackmagic Design Intensity Pro 4K is an internal PCI Express capture and playback card designed to provide high-quality 4K video connectivity for desktop computers, bridging the gap between consumer HDMI devices and professional production software. It allows users to capture footage from 4K cameras, gaming consoles, or set-top boxes directly into their editing or streaming applications, and also play back edited content to 4K televisions or monitors. The card is particularly useful for content creators, gamers, and video editors working in a 4K environment who need a reliable, software-agnostic method to bring an HDMI signal into their computer. It supports the widespread HDMI 2.0 standard, ensuring compatibility with a broad range of modern 4K sources and displays at frame rates up to 60 frames per second.

Installed in a standard PCIe slot, the Intensity Pro 4K operates with low latency, making it suitable for live streaming applications where delay must be minimized. Its drivers present the card as a standard video device within the operating system, enabling compatibility with a wide variety of software including DaVinci Resolve, OBS Studio, Adobe Premiere Pro, and many others. The card also features an analog stereo audio input and output for capturing and playing back sound alongside the video. By offering a straightforward, high-performance path for 4K HDMI video and audio into a PC, the Intensity Pro 4K serves as a versatile and cost-effective solution for upgrading a workstation to handle ultra-high-definition content creation and distribution.
