High-Performance Video and Audio Capture
Available in single and multi-channel models with a wide selection of input interfaces, our high-bandwidth Pro Capture PCI Express cards capture up to four channels of HD or two channels of 4K video plus corresponding audio. Models are available with support for HDMI, SDI, DVI or analog signals and can automatically detect the input signal format, delivering reliable, high-quality video and audio capture for video professionals, systems integrators and OEM developers.
Superb Software and OS Compatibility
Pro Capture devices support Windows, Linux and macOS operating systems – including x86, x64 & ARM architectures – and offer extensive compatibility with popular streaming, live production, web conferencing, lecture capture, collaboration and medical imaging software.
Powerful and Easy-to-Integrate SDK
The Magewell MWCapture SDK provides both generic interfaces and custom APIs across OS platforms, helping developers leverage the full capabilities of Magewell capture hardware and achieve lower-latency, multi-stream capture and AV synchronization across multi-channel or even multiple capture cards.
Lower CPU Usage
All Pro Capture models feature Magewell’s FPGA-based, zero-CPU-usage video processing, providing high-quality up/down conversion and image adjustments without consuming valuable host system processing power.
