    The new USB Capture HDMI 4K Plus supports 4K inputs up to 60fps via HDMI 2.0 connectivity, capturing them at 30fps. 4K inputs with 4:4:4 or 4:2:2 color sampling are automatically converted to 4:2:0 for capture in the NV12 or I420 color space formats, to fit within the bandwidth available in the USB 3.0 standard. 

    Like existing Magewell USB video ingest solutions, the newest USB Capture Plus models enable all types of computers including laptops to capture professional video and audio signals through a standard USB 3.0 interface, with no additional power source required. Available with SDI or HDMI inputs, the 4K USB Capture Plus devices capture resolutions up to 4096x2160, including 3840x2160 Ultra HD.

    The USB Capture HDMI 4K Plus offers loop-through connections, reducing workflow costs and complexity by enabling source signals to be sent simultaneously to additional displays or equipment without the need for external splitters or routers. This cost-effective convenience combines with the devices' rich feature set and extensive compatibility to make them ideal for both end-user applications and as 'glue' solutions for systems integrators implementing complete 4K projects.


    Both 4K USB Capture Plus devices support embedded audio in the SDI or HDMI input signal, as well as separate audio inputs and outputs for capture and monitoring: line-level analog input and output connections on the USB Capture SDI 4K Plus, and an analog microphone input and stereo headphone output on the HDMI model.

    The new 4K USB Capture Plus devices feature FPGA-based video processing, providing high-quality deinterlacing, up/down conversion and image controls while maximizing CPU availability for third-party software. FPGA-based audio processing featuring ASRC technology delivers superior USB audio handling, while the included USB Capture Utility software gives users advanced control of processing settings and access to detailed status information.

    The USB Capture HDMI 4K Plus support Windows, Mac and Linux operating systems, and offer broad compatibility with popular streaming, encoding, live production, collaboration, video conferencing and lecture capture software.

    These new external devices are the latest Magewell offerings that support the growing demand for 4K capture. Multiple models in the company's Pro Capture family of PCIe cards capture full-resolution 4K video at up to 60fps from a flexible choice of input interfaces, while the high-definition USB Capture HDMI Plus model can down-convert 30fps 4K inputs to HD for capture and recording.hdmi 4k plus.PNG

    Capture Format Setting

    Set the capture resolution, frame rate and color space. If the capture format is different with the input format, the FPGA in the capture device will automatically do up/down scaling, causing 0 CPU usage. This function is especially useful when scaling by software causes much CPU burden. 

    Audio Volume Control

    The Utility V3 can control the volume of the audio input (recording) and output (playback) of the USB capture (Plus) devices. The functions differ with models. If the system volume is changed, the parameter on the Utility V3 will also change accordingly. Users can click on the icon to quickly mute/unmute a playback/recording device.

    Utility V3 also provide functions such as cropping, deinterlacing, device name setting, aspect ratio conversion, timing adjustment, status image setting, etc.

    For detailed introduction of the settings and functions, please check the Utility V3 User Manual.
