Overview
The BG-4KCHA is an advanced USB-C 4K video capture device with a scaler, HDMI 2.0 loopout, audio, and HDR10 to SDR conversion, designed for professional HDMI video signal capturing. It uses a USB 3.1 Type-C Gen 1 (USB 3.0) interface, allowing for high-speed transmission. Additionally, the HDMI input and loopout can support up to 4K2K@60, enabling users to connect the BG-4KCHA to a 4K@60 source and capture Ultra HD (4K2K@30) video. With the capability to capture and display uncompressed HDMI video, the BG-4KCHA provides more realistic color renditions. Moreover, the BG-4KCHA employs large volume image buffer technology to effectively avoid video tearing, while the high sampling rate and accuracy result in captured videos with high sharpness, rich details, and fewer color edges.
Furthermore, the HDR10 to SDR conversion allows Playstation and Xbox players to enjoy 4K2K@60 HDR games on a 4K TV through the loopout HDMI port and record real-time 4K2K@30/1080P@120 video streams with SDR quality through the USB 3.0 port simultaneously. With its versatility and features, the BG-4KCHA is a highly capable and professional-grade HDMI video capture device for demanding applications.
* PS5 & Xbox Series X also support 1080P120.
