The Purplelec 4-channel HDMI capture card is a commonly configured PCIe 2.0 card that can be used to capture four channels of HDMI input to your computer. The card supports multiple color sampling modes, 10-bit video processing, up to eight audio channels per input at 48 kHz, and output resolutions up to 2048 x 2160 and frame rates up to 144 fps. The card also features a variety of video processing functions, including cropping, scaling, deinterlacing, aspect ratio conversion, color format conversion, video frame rate conversion, and video OSD compositing.
The 4-channel HDMI capture card supports multiple cards and multiple capture streams per system, and the parameters of each stream can be adjusted independently. Other features include low latency mode, high-speed memory, and 24-hour continuous operation. The card supports the included software on Windows, Linux, and Mac operating systems, as well as multiple APIs for Windows and Linux. It also provides a Windows SDK for easy integration.
High-Performance Video and Audio Capture
Our high-bandwidth capture cards are available in single- and multi-channel models with a variety of input interface options to capture up to four channels of HD video or two channels of 4K video and corresponding audio. These models support HDMI, SDI, DVI, or ana-log signals and can automatically detect the input signal format, providing reliable, high-quality video and audio capture for video professionals, system integrators, and OEM developers.
Excellent Software and OS Compatibility
HDMI capture card devices support Windows, Linux, and macOS operating systems (including x86, x64, and ARM architectures), and provide broad compatibility with popular streaming, live production, web conferencing, lecture capture, collaboration, and medical imaging software.
Powerful and Easy-to-Integrate SDK
The SDK provides a common interface and custom API across OS platforms to help developers take full advantage of the full capabilities of Magewell capture hardware to achieve low-latency, multi-stream capture and AV synchronization across multiple channels and even multiple capture cards.
