4K HDMI-to-USB3.0 Capturer & Recorder - 

The SY-XTREAM HDMI to USB video recorder with HDMI bypass can support resolutions up to 18Gbps (600MHz) 4K UHD with HDR (via the bypass path) while simultaneously streaming the audio and video signal at 1080p to a USB connected PC for capture or re-broadcast. HDMI sources up to 1080p are supported for capture without scaling, while 4K sources are automatically scaled down to 1080p. The use of a special video timing stabilisation feature helps to ensure that the USB capture stream does not lock up or drop, even if the HDMI input source is intermittent or becomes disconnected. Digital stereo audio from either HDMI (LPCM 2.0) or the 3.5mm analog audio input is captured with the HDMI video source and is selectable within the configuration software. USB capture is achieved using the UAC (USB Audio Class) and UVC (USB Video Class) standards, allowing the unit to support most common video capture, chat or streaming software, including support for the Free OBS (Open Broadcaster Software) streaming software which is available for Windows PC, macOS and Linux.
